42-623: The Miles M.57 Aerovan was a British twin-engined short-range low-cost transport aircraft designed and produced by Miles Aircraft . It was primarily used for freight and passenger services. Development of the Aerovan started during the latter years of the Second World War as an affordable freighter suitable for both civilian and military purposes. It was suited to austere operations, and possessed an atypically high payload capacity for its power output. Relatively large payloads, including
84-552: A 5/6th scale replica of the Armstrong Siddeley Mamba turboprop nacelle for the Miles Marathon ; it was also subsequently outfitted with ailerons in line with the standard flaps. Even prior to the Aerovan entering quantity production, Miles had ambitions to produce multiple derivatives of the type. One such design was a specialised aircraft for the air observation post role, intended to be operated by

After 17 days of sitting, the jury stopped the case against Miles and Sir William, and they were discharged. They had appeared on charges of inducing people to acquire shares in the company by making a misleading forecast and dishonestly concealing a material fact in a prospectus. According to Flight , "Twenty of

However, Miles' work was not met with approval, the company being censured for building the aircraft without authorisation and work on the project was suspended on the ministry's orders. Work on the Aerovan
210-648: A diverse range of operations; more obscure uses included the movement of livestock across the English Channel and as a flying removal van . The majority of Mk 3 and 4 Aerovans were employed on passenger and freight services, charter work and joyriding in the UK and in the Near East . Meridian Air Maps operated Aerovan 4 G-AISF on aerial survey work from October 1955 until it crashed on takeoff from Manchester (Ringway) on 29 April 1957. The accident resulted in
252-445: A four-man crew and featuring an enlarged glazed canopy to provide an all-round view in combination with a glazed rear fuselage section. Work was also undertaken on a flying boat derivative that would have had a single-step hull, keeping the rear freight door above the waterline with the assistance of two stabilising floats carried on outriggers set on either side of the hull. Both designs would have retained significant commonality with
294-471: A large clear perspex canopy which formed the front dorsal part of the pod, while the pod-shaped fuselage was lined with four or five circular windows on either side for use by passengers. Access to the cabin and cockpit was via a door on the starboard side. For additional comfort, amenities such as soundproofing were typically installed. The Aerovan's lifting capabilities were such that payloads could weigh up to one tonne, along with sufficient volume to enable
336-686: A pair of Blackburn Cirrus Major piston engines. To facilitate easy loading, the entire rear of the fuselage was a door, necessitating the use of a relatively high tail boom. The prototype was constructed at Miles' Woodley factory in Berkshire . On 26 January 1945, this prototype conducted the type's maiden flight , piloted by Tommy Rose. The performance of the prototype was immediately positive, proving to be both comfortable and relatively easy to fly. It proved to have an atypically high payload capacity for an aircraft of such power, being capable of lifting payloads in excess of its own weight when operated in
378-606: A prospectus was issued in March, 1947 (before the accounts for 1946 were published), the directors should reasonably have been expected to know that all was not well with the company, and when, in August, 1947, a dividend of 7% per cent and a bonus of 24% were recommended, they should reasonably have been expected to know that a big loss was being suffered by the company. Charges were brought against Sir William Malcolm Mount and F. G. Miles. There were 24 charges regarding publication of
420-545: A range of curious prototypes. A company was founded in 1928 by Charles Powis and Jack Phillips as Phillips & Powis Aircraft (Reading) Ltd . In 1929 they opened Woodley Aerodrome , near the town of Reading , Berkshire. In 1936, Rolls-Royce bought into the company. Although aircraft were produced under the Miles name, it was not until 1943 that the firm became Miles Aircraft Limited when Rolls-Royce's interests were bought out. The company needed to increase production of
462-475: A rescue plan could not be drawn up until the audit was completed. The principal trade creditors were: Blackburn Aircraft Ltd., De La Rue Extrusions Ltd., Smiths Aircraft Instruments Ltd . and the Sperry Gyroscope Co. Ltd . Mr. F. G. Miles announced the payment of the 4% per cent preference dividends out of his own resources of £8,600. After Miles Aircraft had been taken over by financiers in 1947,

While Miles intended to produce the Aerovan for the British Army as a wartime asset, development was put on hold by order of the Air Ministry until the end of the conflict. On 26 January 1945, the maiden flight of the Aerovan took place. Quantity production formally commenced during 1946, although customer demand exceeded
546-817: A specifically formed company, the Western Manufacturing Estate Ltd, the name "Western" referring to its location on the Woodley aerodrome. This company later merged with the Adamant Engineering Company Ltd. to form the Adwest Group. Miles also manufactured ballpoint pens designed by László Bíró through an associated company, the Miles Martin Pen Co. Ltd. In 1948, F.G. Miles founded F. G. Miles Limited, which continued to produce aircraft under
588-545: The English Heritage Archive ), Miles Development Products Ltd, Miles Electronics Ltd, Miles Marine & Structural Plastics Ltd and Jet Tanks Ltd. The group was initially based at Redhill, but moved to Shoreham in 1953. Miles Electronics was involved in the manufacture of flight simulators; this division merged with the UK arm of the Link Trainer flight simulator company and was later acquired by
630-548: The H.P.R.1 Marathon . The Miles Aeronautical Technical School was taken over by the Reading Technical College . Other products in which Miles had interests included photocopiers; this business became Copycat Ltd, which was acquired by the Nashua Corporation in 1963. The Philidas locking nut unit became an independent company. The bookbinding machinery and actuator production were taken over by
672-508: The Master advanced trainer, as well as the Martinet and Monitor target tugs . The aircraft designed by Miles were often technologically and aerodynamically advanced for their time; the M.20 emergency production fighter prototype outperformed contemporary Hawker Hurricanes , despite having fixed landing gear. The X Minor was a flying testbed for blended wing-fuselage designs, although
714-530: The Singer Corporation . In 1975 Hunting Associated Industries acquired a controlling interest in F. G. Miles Engineering and all its subsidiaries. The company was renamed Hunting Hivolt and Jeremy Miles, the son of Fred Miles (who founded the firm), became a non-executive director on the board. Other companies included Miles HiVolt Ltd and Miles-Dufon Ltd (this company went into administration on 15 April 1980). Design work between F. G. Miles Ltd and

By swapping the engines, the maximum speed could be increased by up to 20 mph and the rate of climb by up to 50 per cent. The Aerovan was principally operated by civilian customers, with demand for the type from such operators outstripping Miles' production capacity. These aircraft were often used for
798-930: The French company, Hurel-Dubois , resulted in the HDM.105 – a standard Miles Aerovan fitted with an Hurel-Dubois high-aspect-ratio wing. This work led to the Hurel-Dubois HD.34 and the Short Skyvan series of aircraft. The company's earlier aircraft include the Hawk Trainer and its military variant, the Magister , as well as the Messenger and the Gemini . During the Second World War, it produced
840-641: The Miles Messenger and to do so it took over a former linen mill in Banbridge , County Down, Northern Ireland for the production of components of the aircraft. A hangar at RAF Long Kesh was used for assembly of the aircraft and flight testing was carried out at the airfield. The company moved to Newtownards following the end of the war in 1946. The company opened the Miles Aeronautical Technical School in 1943 under
882-510: The Miles brand. The company was based on two sites, Redhill Aerodrome and Shoreham Aerodrome . In 1961, the aviation interests were purchased (along with Auster Aircraft Limited ) by British Executive and General Aviation Limited ( Beagle Aircraft ), initially as Beagle-Miles Ltd, with George Herbert Miles as Chief Designer and Technical Director. The company adopted a group structure with subsidiary companies as follows: Meridian Airmaps Ltd (whose collection of aerial photographs forms part of

1050-407: The company's production capacity. The Aerovan was primarily flown by commercial operators, but was also operated by a number of military users. Numerous variants were developed, and further models were envisioned, including a flying boat model; however, production was halted as a result of the company's bankruptcy in late 1947. Work on the Aerovan commenced during early 1944, being envisioned from
1092-514: The configuration being generally reminiscent of the Miles Messenger . The wing featured electrically actuated flaps that could be adjusted to any angle, which were a recent innovation. On the ground, steering was achieved either by differential braking or differential operation of the throttles. The Aerovan had a relatively deep-sided forward fuselage, which necessitated the use of a large fin area. A pair of pilots were accommodated within
1134-525: The country. A single Royal New Zealand Air Force (RNZAF) aircraft was converted for aerial fertiliser spreading , while a second for aeromagnetic survey work, although it proved to be unsuccessful. A single Mark 4 was used for research with a Hurel-Dubois high aspect ratio wing in 1957, being then known as the Miles HDM.105 . The prototype, which was retroactively designated the Mark 1, was later fitted with

Able to use relatively short landing strips, it was repeatedly flown into settlements and Jerusalem airport in the face of defensive rifle fire. On 17 July 1948,
1218-564: The design and manufacture of aircraft was ended by the new Board. At this time the company had some £5 million worth of business in hand, including substantial orders for the Messenger and the Gemini. In 1948 an application by the Board of Trade for the appointment of an inspector to investigate the affairs of Miles Aircraft Ltd. was granted by Mr. Justice Roxburgh. The B.O.T. case was that when

1344-524: The fuselage and the use of porthole windows rather than rectangular ones. Quantity production of the Aerovan properly commenced during 1946; the majority of aircraft sold were to civilian operators, both domestic and overseas, although some military customers, including Israel and New Zealand , also emerged for the type. Following negotiations, a licence was granted for the Aerovan to be manufactured in France, but no such aircraft were ever manufactured in
