After leaving school, Baynes started work in the fledgling aircraft industry with [[Airco|Airco (The Aircraft Manufacturing Company)]] at [[Hendon Aerodrome]].

In 1930, Baynes designed the ''Scud'' light sailplane, built at first by Brant Aircraft Limited at [[Croydon]]. The Scud was successful, and in 1931, Baynes went into partnership with E.D. Abbott as [[Abbott-Baynes Sailplanes Ltd]], of [[Farnham]], Surrey, to build [[Scud I]] sailplanes, and later the ''Scud II'' (1932). In 1935, a ''Scud II'' flown by [[Mungo Buxton]] took the British Height Record for a glider to 8,750 feet (2,666 m).

In 1935, [[Sir John Carden, 6th Baronet|Sir John Carden]], an authority on tank design who was interested in gliding, outlined to Baynes his requirements for a self-launching sailplane. Baynes designed the ''Scud III'' sailplane, built by Abbott-Baynes Sailplanes, which when fitted with an engine was called the [[Carden-Baynes Auxiliary]]. That carried a retractable 249 cc [[Villiers Engineering|Villiers]] engine mounted on top of the fuselage. The engine drove a pusher-propeller and produced 9&nbsp;bhp, and the capacity of the fuel tank was enough to run the engine for thirty minutes.

During the [[Second World War]], Baynes was the aviation adviser to [[Alan Muntz|Alan Muntz & Co]] at Heston Aerodrome, specialists in weapons systems, and he organised an aircraft division of the company.

Leslie Everett Baynes, AFRAeS (23 March 1902 – 13 March 1989) was an English aeronautical engineer.

Early life

[edit]

Born at Barnes, Surrey, on 23 March 1902 the son of James and Florence Baynes. Baynes was educated at Gresham's School, Norfolk, leaving school at the age of sixteen to join an aircraft company. He developed engineering skills at school and in industry.

Career

[edit]

After leaving school, Baynes started work in the fledgling aircraft industry with Airco (The Aircraft Manufacturing Company) at Hendon Aerodrome. From there, he moved on to Short Brothers at Rochester, where he redesigned the Short Singapore flying boat.

In 1930, Baynes designed the Scud light sailplane, built at first by Brant Aircraft Limited at Croydon. The Scud was successful, and in 1931, Baynes went into partnership with E.D. Abbott as Abbott-Baynes Sailplanes Ltd, of Farnham, Surrey, to build Scud 1 sailplanes, and later the Scud 2 (1932). In 1935, a Scud II flown by Mungo Buxton took the British Height Record for a glider to 8,750 feet (2,666 m).

In 1935, Sir John Carden, an authority on tank design who was interested in gliding, outlined to Baynes his requirements for a self-launching sailplane. Baynes designed the Scud III sailplane, built by Abbott-Baynes Sailplanes, which when fitted with an engine was called the Carden-Baynes Auxiliary. That carried a retractable 249 cc Villiers engine mounted on top of the fuselage. The engine drove a pusher-propeller and produced 9 bhp, and the capacity of the fuel tank was enough to run the engine for thirty minutes. The 249 cc Auxiliary is believed to be the lowest-powered aircraft in the history of powered flight.[1]

Also in 1935, the Mignet HM.14 Pou du Ciel "Flying Flea" built and flown by Stephen Appleby, was rebuilt by Abbott-Baynes Sailplanes, incorporating modifications designed by Baynes, who had witnessed its forced landing at Heston Aerodrome. The success of the Flying Flea family of homebuilt aircraft arose from an English translation of Mignet's book, The Flying Flea (1935), showing readers how to build their own aircraft at home. Abbott-Baynes Sailplanes Ltd went into limited production of a developed version named the Baynes Cantilever Pou.[2][3]

Following the death of John Carden in December 1935, in April 1936, Baynes set up Carden-Baynes Aircraft at Heston Aerodrome, and designed the Carden-Baynes Bee, a two-seat wooden aircraft with two Carden-Ford engines in pusher configuration.[4][5]

During the Second World War, Baynes was the aviation adviser to Alan Muntz & Co at Heston Aerodrome, specialists in weapons systems, and he organised an aircraft division of the company. In 1941, he put up a proposal for a detachable wing with a 100-foot wingspan which when attached to a tank would turn it into a glider. This concept was developed as far as the Baynes Bat prototype, with most of the test flights being piloted by Flight Lieutenant Robert Kronfeld.

Baynes also worked on designs for long-range bombers, and the V-22 Osprey was an American aircraft very similar to a bomber design submitted to the British government by Baynes during the Second World War.[citation needed]

After the war, in the 1940s and 1950s, Baynes was busy with research in the area of variable-sweep supersonic aircraft. In 1949 he applied for a patent on his design for a supersonic variable-sweep wing and tail fighter.[6] The design was built and wind tunnel test were completed successfully. However, due to budget constraints at the time, the design failed to receive government backing and was later developed in the US.[citation needed]

He also designed interiors for airliners, invented the vertical lift plane and the high-speed hydrofoil.

L. E. Baynes designed the Youngman-Baynes High Lift Research Aircraft, an experimental flying test-bed for the system of slotted flaps invented by R.T. Youngman. It used components from the Percival Proctor, and was built by Heston Aircraft Company Ltd. Test pilot Flight Lieutenant Ralph S Munday piloted the first flight at Heston Aerodrome on 5 February 1948, carrying the military serial VT789.[7]

A Scud II built in 1935 is still airworthy, and is believed to be the oldest flying glider in the United Kingdom.

Later life

[edit]

Baynes died at Swanage near Poole, Dorset, on 13 March 1989.
