Chu Hummingbird Hummingbird Role - Experimental reconnaissance helicopter Manufacturer - Central Aircraft Manufacturing Company Designer - C. J. Chu First flight - 1948 (exact date unknown) Status - unknown Produced - 2 Number built - 2 The Chu Hummingbird was an experimental co-axial helicopter developed by Chinese aviation engineer Major General C. J. Chu (朱家仁) in China during the 1940s in two versions, designated the Model A and Model B. Model A was a single seat double rotor test craft used for static (non-flying) test and made its debut in March 1948. This model was destroyed when the rotor broke off. A replacement craft named Model B was introduced in 1948 and was able to fly, but the aircraft was abandoned when Chu left for Formosa. Not much is known about either model, as they were abandoned in China after 1949 as Chu evacuated to Taiwan after the victory of the People's Republic of China. A successor model, the CJC-3, was developed by Chu in Taiwan in the 1950s. Specifications (Hummingbird Model A/B) Jia or Model A Number of seats: 1 Engine: Kinner B-5 Rotor diameter: 4.8 m (approx.)

Gen. Chu Chia-Jen First flight - 1943 Number built - 1 The Chu XP-0, also known as the Chu (AFAMF) XP-0, was a Chinese fighter prototype in the Second World War. Development Designed by the Chief of the Air Force Technical Bureau, Major General Chu Chia-Jen, in 1941, the XP-0 was a single-seat fighter monoplane, the single prototype of which was produced by AFAMF in 1943. Based largely on the Curtiss Hawk 75, it was of mixed construction with wooden three-spar wings, welded steel tube fuselage and plywood skinning. It could carry up to four 20 mm cannons underwing, and had capacity to carry bombs via a centreline bomb rack, allowing it to function as a dive bomber. Operational history It was anticipated that the XP-0 would be produced in series at AFAMF No. 1 factory at Kunming, however the prototype was flown for the first time in 1943, at Yangling. After circling the airfield, the XP-0 landed too fast, ground-looped and was written off. In the meantime, the American entry into World War II meant that American fighters were available to the Chinese, removing the need for China to manufacture indigenous fighter aircraft. As such no further production was carried out. No data except armament, construction and engine have survived.
