Williams International’s
FJ44-4A-QPM engine that
powers the Pilatus PC-24
is the latest addition to the
FJ44 family, so it is highly
efficient and reliable.The FJ44 family began in 1992 with
the introduction of the simple, rugged
FJ44-1A. Through elegant engineering
solutions such as blisks (one-piece
bladed disks), a fuel slinger (rather
than injectors), an effusion-cooled
burner (eliminating louvered layers of
sheet metal), and single-crystal turbine
blades, Williams made an engine that
was reliable, easy to maintain, and
inexpensive to own and operate.
The engine spurred the demand
for light jets, and the FJ44 product
line expanded to four base models
plus variants thereof, improving
performance and durability with
each new model. More than 5,000
FJ44 engines are in service, and have
accumulated 11 million hours, and the
FJ44-4A-QPM has built on this legacy.For the PC-24, Williams enhanced its
FJ44-4A engine with several new features:- Quiet Power Mode (QPM) , a
proprietary technology that allows

the core of the engine to be used
as a quiet, efficient, less costly
alternative to a traditional APU- Automatic Power Reserve (APR)
to boost take-off thrust on one
engine in case of an event causing
thrust loss on the other engine - A low-drag, anti-iced, noise
suppressing inlet - An EXACTTM nozzle that passively
vectors thrust to reduce handling forces
making for easier and safer take-offs
(Exhaust Angle Control Technology)
FJ44 engines are backed by the best
customer service in the industry – over
the past 18 years Williams customer
service has outscored all competitors
in surveys of owner-operators, scoring
5% higher than the closest competitor.
And in 2013 Williams added to its
Total Assurance Program (TAP Blue
maintenance plan) coverage that no
competitors can match – including repair
of foreign object damage (FOD) and
incorporation of all service bulletins.
Like all FJ44 engines, the FJ44-
4A-QPM is a two-spool, co-rotating
turbofan engine. More than half of
the air flow bypasses the core and
is remixed with the core airflow
in the exhaust; this configuration
yields high thermal and propulsive
efficiency while minimizing noise.
Engine control is provided by
dual channel Full Authority Digital
Engine Control (FADEC), which
reduces pilot workload by using
redundant computers to set engine
thrust simply based on throttle lever
angle (TLA) and flight conditions,
and to monitor engine speeds and
temperatures to prevent exceedances
that could damage the engine. •
Advancing Business Aviation:
UTC Aerospace Systems
unveils innovative new
solutions for biz jet market
- Proprietary microbiological water
purifier provides lightweight
system that requires minimal
pressure and no electrical power - Environmentally friendly handheld
cabin fire extinguisher meets ICAO
recommendations and EASA
regulations restricting and replacing
the use of Halon 1211 on aircraft
At the National Business Aviation
Association's annual exhibition
recently, UTC Aerospace Systems, a
unit of United Technologies Corp.,
unveiled a pair of innovative new
solutions for the business jet market.
The company's new proprietary
microbiological water purifier consists
of multiple layers to trap pathogens,
remove odours and neutralize
microbes. Compared to existing water
purifiers that use ultraviolet or fine
micron rating methods of sterilization,
UTC Aerospace Systems' purifier is
extremely lightweight at just over 4
pounds and requires minimal water
pressure. In addition, the unit
requires no electrical power or
wiring, has the capacity to purify
4,000 gallons over its lifetime, and
meets bacteria, virus and cyst
reduction per National Sanitation
Foundation (NSF) P231 purifier
requirements.
Currently undergoing prototype
and lab testing, the new purifier is
expected to be fully qualified in
early 2018. It is designed for use in
aircraft galleys, lavatories, potable
water tank outlets and service panel
fills, and can be scaled in size to
meet specific customer and platform
requirements.
Also at NBAA today, UTC
Aerospace Systems launched its
Kidde Halotron BrX™ handheld
cabin fire extinguisher, which uses
a non-Halon, environmentally
friendly fire suppression agent.
The new extinguisher meets the
ICAO recommendations and
EASA regulations restricting and
replacing the use of Halon 1211 on
aircraft, and is designed as a drop-
in replacement for existing Kidde
1211 extinguishers. Halotron BrX™
has passed UL 711 5B, 2B cold
temperature and FAA Minimum
Performance Standard (MPS) tests. •
