PF-1A Engine

Soon after China successfully made its first jet engine, design and development of a new engine started. In August 1956, Shenyang Aeroengine Design Office (SADO) of SEF was formed. Wu Daguan was appointed its director and Yu Guangyu as chief designer. This office later became the Shenyang Aeroengine Research Institute (SARI).

The first design task given to SADO was to develop an engine with WP5 engine as reference, which had the thrust of 15.7 kN (1,600 kgf). The engine was named PF-1A and was going to be installed on the Chinese designed trainer JJ-1. The AIB pointed out: the task was not only to have the thing designed, but also "to train the engineers, accumulate data and to form the design team".

The preparation for the development started from the end of 1956 and the design and the preparation of trail production were completed in 1957. The fact that the engine was to be designed purely by China, gave fresh initiative to the workers. All the detail parts were finished within 100 days and the first prototype was assembled half a year later.

After 20 hours' ground test, the engine made its maiden flight on JJ-1 in July 1958. It proved the first step to the engine design was basically successful. Under the circumstances of lacking design experiences and basic test facilities, this design was practical. It met the principle of ."do the things with one's ability and advance by regular steps."

Later because the end user changed their training system, the development programs for PF-1A engine and JJ-1 trainer were stopped.
