2007 Curtiss-Wright XP-55 kylantysis (kompanijos pavadinimas CW-24) yra 1940-ųjų Jungtinių Valstijų prototipinis naikintuvas, kurį pastatė Curtiss-Wright. Kartu su "Vultee XP-54" ir "Northrop XP-56" jis atsirado dėl Jungtinių Valstijų armijos oro korpuso pasiūlymo R-40C, paskelbto 1939 m. lapkričio 27 d. orlaiviams, kurių našumas, ginkluotė ir pilotų matomumas pagerėjo virš esamų naikintuvų; tai specialiai leido netradicinius orlaivių dizainus. Labai neįprastas dizainas savo laikui, jis turėjo canard konfigūraciją, gale sumontuotą variklį, nuvalomus sparnus ir dvi vertikalias uodegas. Dėl savo stūmimo dizaino jis buvo sarkastiškai vadinamas "Asilu". Kaip ir XP-54, "Ascender" iš pradžių buvo sukurtas "Pratt &; Whitney X-1800" varikliui ir turėjo būti pertvarkytas, kai šis variklio projektas buvo atšauktas. Tai taip pat buvo pirmasis "Curtiss" kovotojas, naudojęs triratį važiuoklę.

General Characteristics and Role

The Curtiss XP-55 Ascender (Curtiss-Sperry Model 24) was an experimental fighter prototype developed for the U.S. Army Air Forces (USAAF) during World War II. It was the product of the 1940 “R-40C” proposal for unconventional aircraft designs, alongside the Northrop XP-56 Black Bullet and Vultee XP-54 Swoose Goose. The Ascender featured a highly radical and futuristic design for its time: a tailless canard configuration with the engine mounted at the rear, driving a pusher propeller. This layout was intended to improve aerodynamics and provide an unobstructed forward field of fire. Despite the design’s potential, the XP-55 suffered from stability issues, poor low-speed performance, and did not live up to performance expectations, leading to its cancellation after three prototypes were built.

Powerplant and Design

Engine: One Allison V-1710-95 (F23R) liquid-cooled V12 engine.
Power Output: 954 kW (1,275 hp).
Propulsion: 3-bladed propeller in a pusher configuration (at the rear).
Maximum Speed: 628 km/h (390 mph; 339 kn) at 5,800 m (19,000 ft).
Range: 1,040 km (650 mi; 560 nmi).
Design Layout: Canard (small horizontal surface in the nose) and a mid-set wing with twin tail booms supporting the rudders. The main wings were swept back slightly.
Pilot Safety: Due to the rear-mounted propeller, the pilot was equipped with a system to jettison the propeller assembly before bailing out in an emergency.

Armament (Intended) and Service

Intended Armament: 2 x 20 mm cannon and 2 x .50 in (12.7 mm) machine guns, all mounted in the nose. (Prototypes often flew with reduced or no armament).
Service History: The first prototype crashed due to a stall/spin in a test flight. Despite modifications to the second and third prototypes, they were ultimately outclassed by conventional and early jet fighters.
Legacy: The XP-55’s radical configuration helped advance research into canard aerodynamics, a concept later successfully used in aircraft like the Saab Viggen and Eurofighter Typhoon.
