CJC-3 was an expermental helicopter developed in Taiwan during the 1950s under the director of Major General C.J. Chu (朱家仁).
Chu was a Chinese aeronautics engineer, who returned China following his graduation from MIT in 1926. [1] Chu joined the KMT National Revolutionary Army and was in charge of an aircraft building plant that made American rotary aircraft and Soviet Polikarpov I-15 in Yunnan.[2]
Chu developed his first helicopter in 1945 called the Hummingbird Model A. The single seat test craft never flew and was used for static tests. The aircraft was damaged when the rotor broke off. Chu began to work on another helicopter called the Hummingbird Model B. This single seat helicopter was similar to the Model A, but it was able to take flight.
Following the fall of the KMT in 1949, Chu was exiled to Taiwan and the helicopter program was scrapped. It was not until the early 1950s did Chu re-surface with a larger tandem helicopter called the CJC-3. This model took flight and tested in Taiwan in 1952. A upgraded version called the CJC-3A was introduced in 1956. Both the CJC-3 and CJC-3A were likely influenced by American helicopter manufacturer Piasecki based on the strikingly similar design.[3]
