ANEC I and II
The ANEC I and ANEC II were 1920s single-engine ultralight aircraft designed and built by Air Navigation and Engineering Company Limited at Addlestone Surrey.
The ANEC I and II, designed by W.S Shackleton, were amongst the earliest ultralight aircraft; they were very small, wooden, strut braced high-wing monoplanes.
The first ANEC I, G-EBHR, first flew at Brooklands on 21 August 1923. It was the first aircraft with an inverted engine, a 696 cc 16 hp Blackburne Tomtit, to fly in the UK.
Two aircraft were built in the UK, and one in Australia by George Beohm, who later went on to design the other aircraft. E. W. Beckman, the owner, intended to enter it in the Low-Powered Aeroplane Competition held at Richmond in December 1924, but it was not completed until the following year. The first of the two built in the United Kingdom in 1923, G-EBHR, was exported to Australia in late 1924.
The ANEC II was an enlarged version of the ANEC I built for the 1924 Lympne light aircraft trials competition.As permitted by revised competition rules, it was a two-seater and its more powerful 1,100 cc Anzani inverted V twin-cylinder had the greatest capacity allowed. The wing area was increased to accommodate the extra weight by a span extension. It was also 5ft longer than the mk I Engine problems kept it from flying in the competition and out of the Grosvenor Trophy race.Just one example was completed.
In 1927 a new owner refitted it with a 32 hp Bristol Cherub III flat twin engine, a larger rudder, and a more conventional undercarriage with larger wheels mounted on a cross axle.In 1931 yet another new owner fitted a heavier 30 hp ABC Scorpion engine, another flat twin and, to keep the weight down,and reworked it as a single seater. It was in this condition when it was acquired by Richard Shuttleworth in about 1937.It is currently airworthy and can be seen at Shuttleworth.
