Cubewano will reveal
dramatically reduced fuel consumption figures in its lightweight
heavy fuel rotary engines at AUVSI's Unmanned Systems North America
2011.
The
British engine maker, which is
exhibiting on stand 1715 at the show, has developed a new injection
system which has as reduced specific fuel consumption (SFC) from
1.1lb/hp/hr at cruise to below 0.6lb/hp/hr across the entire
workable throttle range.
Craig Fletcher, founder and CEO of
Cubewano, said: "Rotary engines are not typically known for their
fuel efficiency, so after conquering the challenge of producing
a
high power to weight ratio rotary
engine which would run on heavy fuel we
turned our attention to reducing fuel consumption.
"Our new injection system, which currently
has a patent pending, has dramatically reduced SFC at full and part
throttle - offering efficient power generation from our
exceptionally lightweight engines."
Cubewano, based near Birmingham in the
United Kingdom, designs, develops, tests and manufactures small,
high quality internal combustion engines. Its
engines were perfected as part
of the U.S. Army's Class 1 increment 2 programme to develop the
next generation of unmanned air vehicles.
The company's range of rotary Wankel
engines is designed to be light, quiet with very low vibration,
running on multiple fuels including heavy fuel (JP8).
All Cubewano engines are fuel injected with
electronic engine management to maximise power, fuel efficiency,
reliability and emissions requirements. All engines are developed
with field requirements in mind.
Cubewano has developed, manufactured and
tested engines with power ranging from 3hp to 16hp in both air and
liquid cooled variants.
