The Hawker P.1052 was a British experimental aircraft that was built by Hawker Aircraft for the Royal Aircraft Establishment to carry out experiments with swept wings.
construction and development
In order to meet the specifications E.38 / 46 of the Ministry of Aviation, the P.1052 was developed. The Hawker P.1052 corresponds to the Hawker P.1040 ( Hawker Sea Hawk ) in most aspects, with the main difference that the wings are swept at an angle of 35 °. The tailplane was reduced in size. The first prototype (VX272) flew for the first time on November 19, 1948 and the second prototype (VX279) on April 13, 1949. In the winter of 1949/1950, both wings and the fuselage of the first prototype were reinforced after structural tests on a third, non- airworthy, airframe. Around the same time, the second prototype was equipped with a variable tailplane. In 1950 this aircraft was converted to a single jet outlet and a swept tail unit under the designation Hawker P.1081 . Its rear fuselage was then reinforced and fitted with a catch hook and delivered with some delay to the first prototype. The only remaining P.1052 was equipped with a streamlined cockpit canopy and a cross tail, this improved its high-speed behavior. In May 1952, after some delay, attempts to take off and land on board the HMS Eagle (R05) were carried out. For this, the P.1052 was equipped with the longer landing gear of the Sea Hawk. The last change to the P.2052 was implemented in June, a tailplane with variable sweep was installed for high-speed tests by the Royal Aircraft Establishment. After an emergency landing in September 1953, the Hawker P.1052 was decommissioned. A rocket motor assisted version of the P.1052 with the Armstrong-Siddeley-Snarler engine, known as the P.1078, was the subject of a design study. However, this was not built as work on the Hawker P.1072, which was based on the unearthed P.1040, was further advanced. No more Hawker P.1052s were built and work shifted to the P.1067 ( Hawker Hunter ). The P.1052 was part of the transition from the straight wings of the Sea Hawk, which was equipped with a centrifugally powered engine, to the swept wing fighter powered by an axial engine, such as the Hawker Hunter.
