The Curtiss XP-62 was a prototype single-engine interceptor aircraft, that was built for the United States Army Air Forces, by the Curtiss-Wright Corporation. It first flew in 1943.
The design sought to have an improved high-altitude performance and higher speeds, at all altitudes, which was to be assisted by the 18-cylinder Wright R-3350 Duplex-Cyclone engine.[1] It was to be armed with four 20 mm (0.79 in) autocannons, a heavier armament than contemporary USAAF fighter aircraft, and was fitted with a pressurized cockpit.
Design and development
[edit]The terms of the contract proposal of 29 April 1941 called for the first flight within fifteen months of the award and meet the following objectives.
- Maximum level flight speed at 27,000 ft (8,200 m) had to exceed 468 mph (753 km/h).
- It was to feature an air-conditioned pressurized cockpit.
- Armament to be either eight 20 mm (0.79 in) cannons or twelve 0.50 in (12.7 mm) machine guns, mounted in the wings.
Two prototypes were ordered; the first designated XP-62 and the second designated XP-62A.
On 2 August 1941, the specifications were amended for the XP-62, reducing the maximum speed to 448 mph (721 km/h) with eight 20 mm (0.79 in) cannons, and increasing the loaded weight by 1,537 lb (697 kg).
During a project review of 1 January 1942, the specification was again revised, with the loaded weight reduced by eliminating four cannons and removing the propeller de-icing equipment.
On 25 May 1942 a contract for 100 P-62 fighters was awarded. However, on 27 July 1942, before production could begin, the contract for the P-62 was terminated by the USAAF because of the effect on deliveries of Curtiss-built Republic P-47G-CU Thunderbolts.[1]
While work on the XP-62A continued, it progressed slowly, owing to its low priority. Delays in delivery of the pressure-cabin supercharger and engine modifications delayed the first flight until 21 July 1943. Only a limited amount of flight testing was carried out before the XP-62A was canceled on 21 September 1943 and full performance characteristics were not obtained. The prototype was scrapped in early 1944.
