Two of the more unusual exhibits at the Midland Air Museum, Coventry Airport, are Boulton Paul P.111A experimental delta VT935 and, looming in the background, Armstrong Whitworth Argosy G-APRL.

Треугольное крыло Р.111 имело угол стреловидности по передней кромке 45". Возможность замены законцовок крыла упростила их сравнительный анализ. Размах крыла самолета с законцовками как на снимке уменьшался до 7,82 м, а площадь - до 25,01 м2, по сравнению с заостренными законцовками.

The sole Boulton Paul P. 111, VT 935 was contracted in November 1946 under Specification E.27146 to research delta wing handling at high speed and first flew some three years, nine months later, on 6 October 1950. The P.111's sole stable-mate, the P. 120, VT 951 employed the same basic wing and fuselage, but carried a much modified fin and rudder, to which had been added an all-flying, or slab tailplane mounted two-thirds up the fin. The P.120 first went aloft early in August 1952. Quite what these machines were envisaged to achieve with the relatively modest 5.100lb s.t of their single Rolls-Royce Nenes begs a host of questions. The highest speed known to have been reached by the P.111 in level flight was Mach 0.935 at 35.000 feet, or 622mph, during 1953 trials. (Boulton Paul)

Built to specification E.27/46 for research into delta-wing aerodynamics, the Boulton Paul P.111 VT935 had a Rolls-Royce Nene engine. Chief test pilot Ben Gunn undertook taxying trials on Pendeford’s grass runway on May 5, 1950, but the first flight took place at Boscombe Down. The little delta is preserved at the Midland Air Museum, Coventry.

The characteristic nose-up ground attitude of the aircraft is apparent in this picture, as is the tall pointed fin - the extreme tip of which was designed to be removable for inflight comparison of sharp and blunt tip profiles.

The short-lived Boulton Paul P. 120, first flown on 6 August 1952, ended spectacularly a little over three weeks later, on the 29th. The highest speed known to have been reached by the P. 120 was Mach 0.68 at 4.000 feet, or 518mph, moments before it lost its left-side elevon. Fortunately, Boulton Paul's Chief Test Pilot, A.E. 'Ben' Gunn ejected successfully, going on to end his career in airport management.

6 августа 1952г.: построенный для изучения аэродинамики дельтовидного крыла и оснащенный двигателем Nene, самолет Boulton Paul P.120 разбился 28 августа, налетав всего 11 часов.
The sole Boulton Paul P. 120 had one of the shortest flying careers of all, even for a research aircraft. The second of two Boulton Paul P.111 research machines, VT951 became the P. 120 when it was decided to equip the aircraft with a revised fin and rudder to which a 'slab', or all-flying tailplane was attached.

VT951, the P.120, was designed to investigate the interaction between a delta wing and a horizontal tailplane. It was painted in the colours seen here - gloss black with a yellow cheatline - in order to steal the 1952 Farnborough Show limelight from Avro’s blue and vermilion pair of 707 research deltas.
