The Chinese CJ-6 was designed to replace the CJ-5 as basic military trainer. Many people think its a variant of the Soviet Yak-18A but the CJ-6 is an indigenous design. The most notable design feature is it has an aluminium alloy structure instead of the steel tube structure of the Yak design.
Early models of the CJ-6 used the 145 hp M-11ER radial engine with similarly disappointing results when it first flew in 1958. Revised power, in the form of an Ivchenko AI-14R engine, didn’t solve the problem, which called for further redesign of the aircraft.
In 1962 the Housai HS6 9 cylinder radial engine of 265HP and matching metal propeller were produced and these became a standard fit for all aircraft until 1965 where the HS-6A engine up-rated to 285HP was made available. This engine has been used up to today and has resulted in a change of designation of the aircraft to CJ-6A. All components in the aircraft are manufactured in China making the type a totally indigenous designed and manufacture aircraft.
The development of the CJ-6 took a total of four and a half years. More than 10,000 of all types are believed to have been produced.
