2. Standard Engine used in
small aircraft
Piston torque and
horsepower are decided by
bore and stroke
Generally powers a propeller
Can be found in most
transportation vehicles
Supercharges and Turbos
can be added to increase
power output
3. A radial engine has 1
or more rows of
cylinders arranged in a
circle around the
crankcase.
Every row must have an
odd number of
cylinders, in order to
operate smoothly.
4. The incorporation of Ethanol into
the production of airplane engines
is a big breakthrough in the fight
for supporting nature and
reducing the amount of fossil
fuels used in everyday flying.
Fagen Inc. has taken Ethanol to a
new level. It is now used for high
performance stunts in air shows,
instead of having low HP.
For Example: The Ethanol-
Powered Fagen MX2 has a
whopping 400+ HP and top speed
of 275 mph.
5. Internal Combustion
engine; uses a rotary
design
4 Stroke Cycle
Developed in the 1950’s
and only recently was
perfected by Mazda
Simpler, Lighter, and have
less moving parts than
piston powered engines of
the same power output
6. Uses updraft from the
props to store energy
Able to use solar power to
help fly
Some have a battery for
takeoff. After takeoff, it
runs completely on solar
power.
Generally glider shaped,
for maximum lift with
minimum power
7. Very inefficient design for an aircraft engine
Drives a compressor which fires into the jet
engine
Very fuel inefficient and produces less or
equal power as a conventional jet engine
8. Low fuel economy, however, cheap and easy to
build.
Not very fast
Pulse jet diagram: First part of the cycle: air flows
through the intake (1), and mixed with fuel (2).
Second part: the valve (3) is closed and the ignited
fuel-air mix (4) propels the craft.
Used in a few
German planes
9. BMW 803 – one of the
most powerful attempts
at a hyper engine.
28-Cylinders, 3950
Horsepower
Crankshaft was too weak,
so they used direct
connected props.
HP/LB ratio is about 0.6
10. Uses direct cycle jet
engines powered by a
nuclear reactor
Soviets were putting in
great effort into
developing the engine
Very unsafe, however
very powerful if
successful
