Ishikawajima-Harima J3

J3
Type Turbojet
National origin Japan
Manufacturer Ishikawajima-Harima
Major applications Fuji T-1
Kawasaki P-2J

The Ishikawajima-Harima J3 was a Japanese turbojet aircraft engine. It was the first jet engine designed and built in Japan after the Second World War and was used to power the Fuji T-1 trainer and as a booster engine in the Kawasaki P-2J patrol aircraft.

Design and development

Development of the J3, the first Japanese post-war jet engine,[1] intended to power the Fuji T-1 jet trainer, was begun in 1955 by the Nippon Jet-Engine Company, with Ishikawajima-Harima Heavy Industries (IHI) being designated prime contractor in 1959.[2][3] The resulting engine was a small, simple axial-flow turbojet.

The first pre-production engine began flight testing in a Curtiss C-46 testbed in February 1960, with production deliveries beginning in April 1962.[4]

Operational history

While the J3 was designed to power the Fuji T-1, it was not ready in time and the first version of the T-1 was powered by imported British Bristol Orpheus engine. The J3-IHI-3 version of the engine equipped the later T-1B version.[4] A more powerful version of the J3, the J3-IHI-7 was used to re-engine the T-1Bs and as booster engines for the Kawasaki P-2J maritime patrol aircraft.[5]

Variants

J3-1
Nippon Jet-Engine Company prototype.[3][6]
J3-IHI-3
Initial production version for Fuji T-1B trainer. 11.8 kN (2,645 lbf) thrust.[4]
J3-IHI-7
More powerful version used as auxiliary engine in the P-2J and to re-engine T-1B trainers. 13.7 kN (3,080 lbf) thrust.[5]
J3-IHI-F
Aft-fan variant[4] — the later Ishikawajima-Harima F3 turbofan engine began flights in 1985.[7]
