New Engine Design Offers Significant Operating Cost Reduction
and Increased Power
Honeywell is crowing (justifiably, no doubt) that its HTS900
turboshaft engine has received its FAA Type Certificate. The engine
was certified to the FAA's FAR Part 33 Amendment 20.
"The Honeywell HTS900 engine is a new type design engine to
provide superior performance at high, hot conditions, fuel
efficiency, and operating costs" said Mike Cuff, Honeywell Vice
President, Helicopters and Surface Systems. "This certification
demonstrates Honeywell's continued success in developing the
world's highest performance turboshaft engines for both the
commercial and military segments.
"The Honeywell HTS900 engine produces more than 1,000 Shaft
Horsepower (SHP) uninstalled at sea level on a standard day - and
has accumulated more than 1,000 flight hours," Cuff said.
"Primary benefits of the HTS900 over previous generation engines
are 5-10% lower fuel burn, on condition maintenance with no hard
time scheduled overhaul limits, and a Dual Channel Full Authority
Digital Engine Control (FADEC) to ease pilot workload and
maintenance planning. Combined, the HTS900 offers operating costs
that are 10 percent lower than previous engines." Some of the new
technologies in the HTS900 include superior high pressure ratio
Dual Centrifugal Compressor, cooled single-crystal turbine blades,
cooled turbine nozzles, effusion cooled combustor liner.
The Dual Centrifugal Compressor configuration increases engine
power output and reduces engine fuel consumption while providing
for future engine power growth.
The on condition maintenance of the HTS900 engine is enabled by
scheduled bore scope inspections which can be performed by the
operator or Honeywell.
