The Williams FJ44 Engine –
Breakthrough
Technology
FJ44-2A
The FJ44-2A is a remarkably
efficient fanjet that provides
superior performance. Applying Williams International’s
third-generation wide-sweep fan
technology, the light weight and outstanding efficiency of the FJ44-2A enables aircraft to attain cruise performance
that is competitive with much larger, more expensive
business jets, while retaining the low operating and
acquisition costs associated with turboprops. The FJ442 was first FAA certified in 1997 and has become the
engine of choice for numerous aircraft.
The FJ44-2A uses the same core and LP turbine as
Williams’ FJ44-1. The unique fan and compressor sections of the FJ44-2A are a direct result of over 30 years
experience with integrally bladed fans and compressors
(blisks) used in various Williams International turbofan engines.
The FJ44-2A maintains the modest turbine temperatures of the FJ44-1 and retains all of Williams
International’s unique low-cost turbofan technology,
such as the uncooled, high-pressure turbine, effusion-cooled combustor, and high-work, two-stage LP
turbine. These components have all been thoroughly
tested and proven for long endurance and long cycle
life in the FJ44-1 program. A version of the FJ44-2 has
been tested to 65,000 feet pressure altitude.
The outstanding combination of thrust, weight, and
specific fuel rate at 40,000 ft., Mach 0.8 makes the
FJ44-2A the ideal choice when you seek cruise performance for the dollar.
FJ44-3A
Ever since the reliable FJ44 family was launched
with the FJ44-1 turbofan, Williams International been
building on its technology and its tradition of success.
The FJ44-3A was FAA certified in 2004. Performance
for this engine is truly breathtaking! Thrust-to-weight
ratio is increased dramatically over its predecessor.
Efficiency improvement gives additional fuel savings.
Truly a world class turbofan engine for FAR 23 and FAR
25 airplanes.
The unique fan and compressor sections of the FJ443A are a direct result of over 30 years experience with
integrally bladed fans and compressors (blisks) used in
various Williams International turbofan engines.
The FJ44-3A maintains the modest turbine temperatures of the FJ44-1 and FJ44-2 while retaining all
of Williams International’s unique low-cost turbofan
technology, such as an uncooled, high-pressure turbine, an effusion-cooled combustor, and a high-work,
two-stage LP turbine.
The remarkable combination of thrust, weight, and
specific fuel rate at cruise makes the FJ44-3A the perfect choice for the utmost in performance and value.
