X-1800 (XH-2600)
Type 24-cylinder H-engine
National origin United States
Manufacturer Pratt & Whitney
First run 1940
Number built 1

The Pratt & Whitney X-1800 (later enlarged as the XH-2600) was an H-block aircraft engine project developed between 1938 and 1940, which was cancelled with only one example being built.

Design and development[edit]

The X-1800 was a watercooled 24-cylinder H-block of 2,240 in3 displacement;[1] this was later expanded to 2,600 in3 displacement.[2] It was intended to be used in the Vultee XP-54, Curtiss-Wright XP-55 Ascender, Northrop XP-56, Lockheed XP-49, and Lockheed XP-58 Chain Lightning. Projected performance was to be 1,800 to 2,200 hp (1350-1640 kW), with a turbocharger to secure high-altitude performance. The designation came from the intended power rating rather than the more usual cubic inch engine displacement figure.[3]

The target date for series production was 1942. In 1940, however, performance on the test bench did not continue to improve, demonstrating a need for considerable additional development effort. Pratt & Whitney subsequently ended development of the X-1800 in October 1940, with only one built, to concentrate on radial engines.
