The new M250-C47E improves efficiency and
performance, using proven technology already
demonstrated in the field. These include a five
percent improvement in ‘hot and high’ power and
a nearly eight percent increase in rated takeoff
power to 700 shaft horsepower. Specific Fuel
Consumption (SFC) is reduced by a typical two
percent and engine reliability is increased.
Greg Fedele, Rolls-Royce, Senior Vice President
Helicopters, said, “The newest evolution of the
M250 engine will deliver improved power and
reliability with reduced fuel consumption. Both
commercial and military customers will benefit
from these improvements as we continue to evolve
the proven legacy of the M250 engine.”
The Allison Model 250, now known as the
Rolls-Royce M250, (US military designations T63
and T703) is a highly successful turboshaft
engine family, originally developed by the
Allison Engine Company in the early 1960s. The
Model 250 has been produced by Rolls-Royce since
it acquired Allison in 1995. Rolls-Royce has
delivered more than 31,000 M250 engines, with
the fleet totalling over 223 Million flight
hours. |
