Description

The FJ44-1 is a two shaft engine featuring a single-stage fan with integral single-stage low pressure (LP) axial compressor and a centrifugal high pressure (HP) compressor. These are driven by a two-stage LP and single-stage HP turbine respectively. The combustion system is single annular.

Rolls-Royce and Williams International partnered in 1989 to design, produce and support the two-shaft FJ44.

The FJ44 family was launched with the FJ44-1 which was certified in 1992. The original business jet application was the Cessna CitationJet, which entered service in 1993. The CitationJet was replaced by the CJ1, which entered service in March 2000. The CJ2 entered service in December 2000. To date, 600 CitationJets, CJ1s and CJ2s have rolled out of the Cessna factory.

Compact and lightweight, the FJ44 brings the smoothness and economy of the turbofan to a sector of the aviation market previously served solely by turboprops.

The Royal Swedish Air Force has re-engined its SK-60 trainers with FJ44-1C engines to give improved performance characteristics and reduced life cycle costs.

The FJ44-2C is an advanced, highly reliable engine designed and qualified for aerobatic manoeuvring. The all-altitude capability, combined with its excellent thrust-to-weight ratio, fuel efficiency, and low acquisition and operating costs, make the FJ44-1C the best choice for trainer aircraft.
