The Blackburn Beverly













I have fond memories of the Blackburn Beverly from when I went inside one as a young teenager at RAF Hendon. This aircraft was sadly scrapped in 1981. I still remember being overwhelmed by the size of it plus the smell of it inside.
The first flight was on the 20th June 1950 (then called the GAL60) this aircraft then evolved into what we know as the Beverly today. A total of 47 were made and only one aircraft survives today at Paull near Hull. They served the RAF well around the world from 1956-67 as a heavy load, short field, dropping aircraft

Arado Ar 232

The Arado Ar 232 (German: "Millipede"), sometimes also called Tatzelwurm, was one of the first truly modern cargo aircraft, designed and built in small numbers by the German firm Arado Flugzeugwerke during World War II. The design introduced, or brought together, almost all of the features now considered to be "standard" in modern cargo transport aircraft designs, including a box-like fuselage slung beneath a high wing; a rear loading ramp (that had first appeared on the December 1939-flown Junkers Ju 90 V5 fifth prototype four-engined transport via its Trapoklappe); a high tail for easy access to the hold; and various features for operating from rough fields. Although the Luftwaffe was interested in replacing or supplementing its fleet of outdated Junkers Ju 52/3m transports, it had an abundance of types in production at the time and did not purchase large numbers of the Ar 232


















The Ar 232 design resulted from a tender offered by the Reichsluftfahrtministerium (German Air Ministry, RLM) in late 1939 for a replacement for the Ju 52/3m transport. Both Arado and Henschel were asked for rear-loading designs powered by two 1,193 kW (1,600 hp) BMW 801A/B radial engines, which was just entering prototype production and not currently used on any front-line designs. The Arado design beat out Henschel's after an examination of the plans, and an order for three prototypes was placed in 1940.

Wilhelm van Nes led the design of the Ar 232. He began at the cargo area, with a bay directly behind the "stepless cockpit" that was 6.6 m (21 ft 7¾ in) long, 2.3 m (7 ft 6½ in) wide and 2.0 m (6 ft 6¾ in) high. Typical designs of the era would use a side-mounted door for access, but the Ar 232 used hydraulically powered clamshell-doors on the rear of the bay with a ramp to allow cargo to be rolled into the hold. The tail control surfaces were mounted on the end of a long boom to keep the area behind the doors clear so trucks could drive right up to the ramp, much like the 1944-era American Fairchild C-82 Packet of a differing twin boom fuselage configuration. The high-set tail on its "pod-and-boom" configuration fuselage allowed the Ar 232 to be loaded and unloaded faster than other designs.

For short-field performance, the Ar 232 incorporated Arado's own "travelling flap" design for the entire rear surface of the wing. Even loaded to 16,000 kg (35,270 lb), it could take-off in 200 m (656 ft). This distance could be further reduced by using rocket assist (RATO) for take-off, and either parachutes or reverse RATO for landing.

The most noticeable feature of the Ar 232 was the landing gear. Normal operations from prepared runways used a tricycle gear, but the struts could "break", or kneel, after landing to place the fuselage closer to the ground and thereby reduce the ramp angle. An additional set of ten or eleven smaller, non-retractable twinned wheels per side supported the aircraft once the main landing gear's lever-action lower oleo-strut suspended arm - carrying the main gear's wheel/tire unit - was "broken", or could be used for additional support when landing on soft or rough airfields. The aircraft was intended to be capable of taxiing at low speeds on its row of small wheels, thus being able to negotiate small obstacles such as ditches up to 1.5 m (5 ft) in width. The appearance of the row of small wheels led to the nickname "millipede". In flight, the main legs fully retracted into the engine nacelles, while the fixed support wheels remained exposed and the nose wheel only semi-retracted.

Normally operated by a crew of four, the pilot was the only member without two roles. The navigator operated a 13 mm (.51 in) MG 131 machine gun in the nose, the radio operator a 20 mm MG 151 cannon in a rotating turret on the roof, and the loadmaster a 13 mm (.51 in) MG 131 machine gun firing rearward from the extreme rear of the cargo bay above the cargo doors

Even before the prototypes were complete in 1941, the Focke-Wulf Fw 190 project had been earmarked to use the BMW 801A/B, and was proving to be a capable design. Production of the BMW 801 was insufficient to supply this new demand, and the Ar 232 was forced to use another engine. Eventually, the BMW Bramo 323 from the Junkers Ju 352 was selected instead, as it was already in production and could meet requirements if the Ar 232 really did replace the Ju 52/3m in service. The prototypes were far enough along that switching engines would have seriously delayed the program, so the first two were to be completed as the Ar 232A, and the third and a newly ordered fourth as the Ar 232B. The third and fourth prototypes (and all production aircraft) used four engines (in place of the two specified in the RLM specification) in order to provide the desired performance.


The first two prototypes, bearing the Stammkennzeichen alphabetic codes GH+GN and VD+YA respectively, started trials in early 1941. The first flight resulted in the collapse of the nose gear, but the millipede wheels saved the aircraft from damage. A further ten pre-production machines were built, and were used operationally as the Ar 232A-0 while awaiting production versions. In general, the Ar 232 completely outperformed the Ju 52/3m. It carried roughly double the load over longer distances, operated from shorter runways and rougher fields if need be, and cruised about 70 km/h (44 mph) faster.

The Ar 232B program ran at the same time. With four 895 kW (1,200 hp) Bramo 323s, power increased from 2,386 kW (3,200 hp) to 3,580 kW (4,800 hp), solving the A model's problem of having little excess power in case of engine failure. This change also required the wing to be extended slightly, the span increasing just over 3 m (9 ft 10 in) in total. The extra weight of the engines also moved the center of gravity forward, which was offset by extending the cargo area rearward another meter.

Two four-engined prototypes were ordered, the V3 and V4, and V3 first flew in May 1942. A further 10 were then ordered as the Ar 232B-0, and were used widely in an operational role. However, this was the only order for the design, as the Luftwaffe gave transport aircraft production a very low priority. Many of those produced were used by Arado to transport aircraft parts between its factories, and did not see front-line service.

Plans were also made to replace the outer wing sections and control surfaces with wooden versions to conserve aluminium. Originally to be known as the Ar 232C, the design dragged on and was later renamed the Ar 432. Plans were finally put into place to start production in October 1945, but the war ended without even a prototype being produced. Two even larger planned versions, the Ar 532 and the Ar 632, would have almost doubled the wingspan to 60 m (196 ft 10 in) and added another two engines.

Two of the B-0s were captured by British forces at the end of the war. After test flights by Eric "Winkle" Brown, who gave the design excellent marks, they were used by the Royal Air Force on flights between England and Germany after the war.

Payen PA-22/PA-112

Roland Payen evolved a radical tandem-wing configuration which he dubbed the Fléchair, the short-span tapered foreplane carrying a combination of ailerons and flaps and the 67-deg aft plane carrying combined elevator-flaps, the pilot’s cockpit fairing into the vertical tail surfaces. In 1938, Payen proposed to the Ministère de l’Air a lightweight fighter version of the PA 112, a racing aircraft then being developed by the Sociêté Co-operative d’Etudes et Productions Aéronautiques (SCEPA) to the Fléchair configuration and intended to participate in the 1939 Coupe Deutsch de la Meurthe. The PA 112 was to be a retractable monowheel undercarriage with outrigger skids retracting into the aft plane. Weighing only 948 lb (430 kg) empty and 1,345 lb (610 kg) loaded, the PA 112 had extremely small overall dimensions which included a span of 13 ft 7¾ in (4,16 m) and a length of 22 ft 1 in (6,74 m), height being 6 ft 11 in (2,11 m), and it was rather optimistically anticipated that a maximum speed of 360 mph (580 km h) would be attainable. The projected lightweight fighter derivative, the PA112 Cl, was to have had two wing-mounted 7,5-mm machine guns and a 20-mm cannon firing through the extension shafts of the Salmson engines, and an elaborate mock-up of the proposed PA112 Cl was built, this, in fact, utilising the airframe of one of the two PA 100 Coupe Deutsch racing aircraft. Possibly as a result of the dramatically unorthodox nature of the proposed PA 112 Cl, no contract was forthcoming from the Ministère de lAir.
























Although no example of the PA 112 was completed and the 1939 Coupe Deutsch was destined never to take place, development of the Fléchair concept continued with the PA 22 which was of similar configuration to the PA 112 but had a conventional engine installation and a conventional fixed tailwheel under-carriage. The PA 22 had originally been built to test the Mèlot ramjet but was eventually to be completed in 1939 with a 180 hp Régnier R6 inverted inline air-cooled engine. After completion, it was mounted in the Chalais- Meudon wind tunnel where it was found by the German occupation forces who expressed some curiosity as to its possible flying characteristics. Accordingly, it was transferred to Villacoublay where it was flown for the first time by Jacques Charpentier in October 1942. A flight test programme was conducted, but before this could be completed, the German authorities decided that the PA 22 should be taken to Rechlin. However, on the pretext that a number of modifications were necessary, Payen succeeded in having the prototype returned to his factory at Juvisy where it was intended to make changes to the undercarriage, mount supplementary fuel tanks and fit a variable-pitch propeller. In the event, these modifications were still in process when the factory was hit during an Allied bombing raid on the Juvisy railway yard, the PA 22 being destroyed.

The DH.91 Albatross. One of the most beautiful British airliners ever built.

Frobisher
















The aircraft was remarkable for the ply-balsa-ply sandwich construction of its fuselage which was later made famous in the de Havilland Mosquito bomber. Another unique feature was a cooling system for the air-cooled engines that allowed for nearly ideal streamlining of the engine mounting. The first Albatross flew on May 20, 1937. The second prototype broke in two during overload tests but was rebuilt and it and the first prototype were used by Imperial Airways.

Although designed as a mailplane, a version to carry 22 passengers was developed; the main differences were extra windows and the replacement of split flaps with slotted flaps. Five of these made up the production order delivered in 1938/1939.

Operational history:
As normal for the Imperial Airways fleet of the time, all were given names starting with the same letter, and the first aircraft's name was also used as a generic description for the type overall, as "Frobisher Class". This tradition, which came from a maritime and railway background of classes of ships and locomotives, lasted well into post-war days with BOAC and BEA.

The first delivery to Imperial Airways was the 22-passenger DH.91 Frobisher in October 1938. The five passenger carrying aircraft were operated on routes from Croydon to Paris, Brussels and Zurich. After test flying was completed the two prototypes were delivered to Imperial Airways as long-range mail-carriers. The only significant season of their operation was the summer of 1939, when they were the main type on the two-hourly London Croydon to Paris Le Bourget passenger route.

With the onset of World War II, the Royal Air Force considered their range and speed useful for courier flights between Great Britain and Iceland and the two mailplanes were pressed into service with 271 Squadron in September 1940. Both aircraft were destroyed in landing accidents in Reykjavík: Faraday in 1941 and Franklin in 1942.

The five passenger aircraft were used by Imperial Airways, (BOAC from September 1940) on Bristol-Lisbon and Bristol-Shannon routes from Bristol (Whitchurch) Airport. One aircraft Frobisher was destroyed during a German air raid on Bristol in 1940, One (Fingal) was destroyed in a crash landing following a fuel pipe failure in 1940 at Pucklechurch, while Fortuna crashed near Shannon Airport in 1943. This accident was found to be due to deterioration of the aircraft's plywood wing structures. The two surviving aircraft were found to have similar problems and so Falcon and Fiona were scrapped in September 1943.

Aircraft:

Faraday
Mail carrier variant was delivered to Imperial Airways in August 1939 as Faraday and registered G-AEVV. It was transferred to BOAC when it was formed in 1940 but was impressed into Royal Air Force service with serial number AX903 for operation by No. 271 Squadron RAF. It was destroyed in a landing accident at Reykjavik on the 11 August 1941.

Franklin
Mail carrier variant was delivered to BOAC as Franklin and registered G-AEVW. Impressed into Royal Air Force Service with the serial number AX904 for operation by 271 Squadron. It was destroyed when the landing gear collapsed on landing at Reykjavik on the 7 April 1942.

Frobisher
Passenger variant was registered G-AFDI and delivered to Imperial Airways (later BOAC) as Frobisher in 1938. It was destroyed on the ground during a German air attack on Whitchurch Airport on 20 December 1940.

Falcon
Passenger variant was registered G-AFDJ and delivered to Imperial Airways (later BOAC) as Falcon in 1938. It was scrapped in September 1943.

Fortuna
Passenger variant was registered G-AFDK and delivered to Imperial Airways (later BOAC) as Fortuna in 1939. Destroyed in a crash landing near Shannon Airport, Ireland on 16 July 1943.

Fingal
Passenger variant was registered G-AFDL and delivered to Imperial Airways (later BOAC) as Fingal in 1939. Destroyed in a crash landing near Pucklechurch, Gloucestershire, England on 6 October 1940.

Fiona
Passenger variant was registered G-AFDM and delivered to Imperial Airways (later BOAC) as Fiona in 1939. It was scrapped in September 1943.

Operators;
Imperial Airways which was reorganized as British Overseas Airways Corporation received all seven aircraft.
Royal Air Force
No. 271 Squadron RAF operated two aircraft taken over from BOAC.

Focke-Wulf Fw 187

The Focke-Wulf Fw 187 Falke (Falcon)... was developed as a high-performance fight in the late 1930s. Designed by Kurt tank was also behind designing the beautiful looking Fw 200 Condor. The Luftwaffe in the end did not feel it fitted in with what they wanted and in the end only nine were built.
It first flew in May 1937. One and two seat prototypes we built. It suffered with trouble during development. One aircraft crashed after stalling, a couple crashed on landing and after an engine fire. Operationally three were used to defend of F-W’s factory. Another three were used in Norway, and one was used in Denmark. Pilots reported it was as good if not better than the Bf 110! It certainly looked better.

Handley Page Herald


LAU  HP.7 Herald 101 HK-715 c/n151









Page updated 30/8/15
In the mid 1950s the Handley Page Aircraft Company developed a new fast short-range regional airliner, intended to replace the venerable Douglas DC-3, particularly in third-world countries. The design, originally known as the HPR-3 Herald, emanated from the drawing office at Handley Page (Reading) Limited - the former Miles Aircraft factory site, which had developed an earlier airliner design, the Miles Marathon. The Herald was an extensive re-development of the original concept of the Marathon, notable for its high mounted wing. The HP Reading division succeeded in producing a modern design with excellent flight and performance characteristics. However, the company made a serious misjudgement which was, in the end, to cost the company dearly, and the Herald missed its chance, like some other classic British aircraft of the time.

demonstrating at the Farnborough Airshow in September 1955

A couple that never got off the drawing board:
HP .127

HP.124
































The HPR-3 Herald originally had four piston engines, like the smaller Marathon. The Herald's engines were 870 hp (650 kW) Alvis Leonides Major 14-cylinder radial piston engines, driving three-bladed propellers. By now, however, the Rolls-Royce Dart turboprop engine had shown proven success in the Vickers Viscount. HP failed to take early account of this in the Herald design phase; particularly the market desire for the new turboprops. This misjudgement and the ensuing delay was to prove a costly mistake for the company.
However, the Herald was advanced in many ways for the time. Its pressurised cabin up to 30,000 ft (9,140 m), could seat up to 47 passengers in the series 100 (up from 44 originally) and could easily exceed 300 mph (480 km/h) in level flight. Initial climb rate was over 1,800 ft/min. The first "Herald" prototype, G-AODE, first flew on 25 August 1955 and was demonstrated at the Farnborough Air Show two weeks later. Although Queensland Airlines, Australian National Airways, and Lloyd Aéreo Colombiano had initially placed 29 orders, these were later cancelled with only the first prototype completed. As a result Handley Page belatedly realised it had to make a major change to the engine configuration, if the Herald was to have any chance in the market.
There had already been a very substantial investment in the Herald project, such that the Management held a meeting to discuss continuation. Handley Page decided to press ahead with the Herald project, in an effort to recover the investment; announcing a new uprated version, reworking the wing to use Rolls-Royce Dart turboprops fitted with 12.5 ft (3.81 m) variable pitch four-blade Dowty Rotol props, and lengthening the fuselage by 20 in (51 cm). The first prototype series 100 first flew in 1958. Now designated the HPR.7 Dart Herald, the new aircraft entered production in 1959. The first order was placed by BEA.
The Herald attracted much early interest around the world because of its astonishing short field performance and excellent flight characteristics, but Handley Page failed to close many of the deals, as the F-27 and the HS.748 had become rival offerings, both of which were significantly cheaper. There has been some speculation about the origin of the F-27 design, which first flew earlier than the Herald in turboprop configuration. A key design feature of the Herald was the high mounted wing but notably with an upswept dihedral. In addition, the Herald's vertical fin is covered in miniature aerofoils, adding further to the Herald's excellent stability.
Pilots reported the Herald flew like a dream; very stable in the air, yet highly manoeuvrable even at slow speed. Ground handling was said to be the Herald's only vice due to an overlarge tail fin. Credit for the Herald's useful wing and aerofoil features was due to the company's wing design office, which had garnered an unrivalled reputation for advanced wing design, including the crescent wing of the Victor bomber. Handley Page invented the Slot, later referred to as the Handley Page Slot, without which most modern aircraft would not be nearly so easy to manage at slow speeds.Despite the rework, that transformed the HPR.3 to the HPR.7 Herald, only four of the original 47 seat Series 100 HPR.7s were built. Believing a yet larger version was needed, HP turned to Series 200 production, which featured a further 3 ft 4 in (1.07 m) stretch of the fuselage, seating up from 47 to 56 and corresponding increased weights. Series 200 production began in 1961. The first production model was delivered to Jersey Airlines in January 1962. However, by this point all sales momentum had been lost, and only 36 examples of this major production model were eventually built during the six years of production.
The Herald Series 400 was specially developed in 1964 as a "tactical transport" built for the Royal Malaysian Air Force, with a strengthened cabin floor. HP suspected that the Herald was still too small and so a 60-seater Series 700, powered by Dart 532s and having increased fuel and weights was designed.
A late attempt was made to revive sales when speculative production commenced on eight Series 700 airframes. The project was cancelled as several of the airframes were approaching completion. The partially completed airframes were scrapped. The 50th, and last, Herald (a series 200 for Israel's Arkia) was flown and delivered in August 1968, after which Herald production ceased and attention turned to the HP.137 Jetstream.
The Herald's last ever passenger flight was operated by British Air Ferries in 1987 doing subcharters for Ryanair on the Waterford-Luton route.  A durable and reliable aircraft, capable of being heavily worked, many continued on as freighters, plying the night sky across Britain and the near continent, for several operators including Royal Mail, BAF, Channel Express, DHL, Elan, Securicor and others; transporting papers, milk, parcels, post, tomatoes, flowers, and other goods round the clock. Some aircraft were in a specially convertible configuration, flying passengers by day and goods all night, but by 1999 the only one remaining in service, was a series 400 G-BEYF with Channel Express; it was retired at the end of March that year.
It is widely thought that the misjudgements made during the Herald project, necessitating major design changes so late in the design cycle, was to prove the company's fatal mistake. Moreover, HP had been doggedly independent throughout its history. The UK Government favoured placing orders for military and civilian aircraft with the newly merged aircraft constructors, British Aircraft Corporation (BAC) and Hawker Siddeley (HS). Sir Frederick Handley Page was very much against consolidation. Even after his death in 1962, the company continued to plough on as an independent constructor. But this policy saw HP lose out to BAC and HS in military and civilian orders by Government, with the notable exception of the HP Victor, which sold on its undoubted merit.
The demise of Handley Page was unfortunate. The company made a series of catastrophic errors, not least of which was failing to judge the changing needs of the airlines that expressed early interest in the Herald. The company did not have the stomach to press ahead in a difficult economic climate effectively competing with a much larger company. Development of the Herald had proven to be an extremely expensive project. Despite much hope over the Jetstream 137, and possible new variants of the Herald, with eight speculative builds at various stages of completion, Management made the difficult but brave decision to wind the company up.
Handley Page went into voluntary liquidation on the close of its books on 31 March 1970. The profitable HP.137 Jetstream operation and drawing and design staff were the only useful parts of Handley Page left, but it was not enough for the company to survive as Handley Page. The Jetstream operation was sold and transferred to Scottish Aviation, later to become a subsidiary called Jetstream Aviation. This company was later acquired by and absorbed into British Aerospace. The Jetstream went on to be a successful commuter airliner.
A belated attempt to revive the Herald design as a pure jet-powered development was shown in model form at the Farnborough Airshow in 1962. The basic Herald components were incorporated along with a stretched fuselage, with two Rolls-Royce Spey turbo-fan engines slung in pods under the wings. Other modifications included a shorter wingspan and revised tailplane mounted midway up the vertical tail. No interest was evoked in the "Jet Herald" with the project being stillborn.

Vickers Vanguard

The Vickers Vanguard was introduced in 1959 as a development of the successful Viscount. It came into service just before the first of the large jet-powered airliners that in the end stole it's thunder. Just 44 were built, with deliveries to Trans-Canada Air Lines (TCA) and British European Airways (BEA).
Both airlines converted a lot of them to freighters and this gave them a new lease of life as they ended up with other carriers. The last one retired to Brooklands in 1996 and is the only one remaining fully intact.

Boulton Paul Defiant

The Boulton Paul Defiant was a two-seat fighter with a four-gun power-operated turret. It had no forward firing armament, which meant it could not shoot down enemy aircraft from behind. It was intended primarily as a bomber interceptor, but the turret fighter concept was outmoded and the extra weight made the aircraft sluggish in combat. In early battles over Dunkirk, Defiants had proved very vulnerable to conventional enemy fighters. RAF Fighter Command rashly sent its two Defiant squadrons - Nos. 141 and 264 - into action in July and August, which resulted in two separate massacres at the hands of the Luftwaffe. As a consequence the aircraft played no further part as a day fighter in the Battle.

DH.89 Rapide on floats


Several (about 10 as far as I can find out) Dragon Rapides were adapted for service on floats. The floatplane adaptations were performed by De Havilland of Canada, where they were fitted with Edo floats and a long dorsal fin.
