HTS900 Incorporates New Compressor Technology and Dual Channel
FADEC, Certification Expected by Mid-2006
As previously noted on
ANN, Honeywell has been selected to provide its new HTS900
turboshaft engine for future integration for Bell's Model 407
helicopter.
The HTS900 incorporates and features new compressor technology
for improved performance, producing more than 925 Shaft horsepower
at Takeoff Power rating at sea level on a standard day. The engine
is expected to deliver Specific Fuel Consumption levels of .54 lb
per shaft horsepower or a 5% decrease from earlier Honeywell
helicopter engines.
The HTS900 has successfully completed the first engine to test
(FETT), with a production version dual-channel full authority
digital engine control (FADEC), achieving all designed power
specifications. The dual-channel FADEC will ease pilot workload,
provide reduced support cost and simplify maintenance
procedures.
"Our new engine includes a next generation impeller, offering
state of the art aerodynamic efficiency and a rugged wide chord
axial compressor for improved erosion resistance and tolerance to
foreign object damage," said Barry Eccleston, Vice President,
Propulsion, Honeywell Engines Systems & Service. "The engine
utilizes a new cooled gas producer (GP) turbine and shroud assembly
that will deliver increased power with extremely low fuel
consumption, and have a minimum of 15,000 component cycle lives.
This combination results in very low operating costs for our
customers."
"Operators will be able to choose engine output shaft speeds
from either a 6,317 RPM version or a 9,598 RPM version for either
single and twin engine applications," said Bob Miller, Director,
Honeywell Utility and Light Helicopter programs. "Honeywell's
commitment to the helicopter industry is to continually upgrade and
improve its turboshaft engines for all rotor wing applications. Our
engine enhancements give operators improved performance,
reliability and reduced maintenance costs."
The HTS900 is based on the LTS101 family of engines that are
recognized for high reliability and low direct operating cost.
