Thrust Propulsion - CORRECT ANSWER-Methods of generating thrust that
involve increasing the velocity of a flow of air in a direction opposite to the
proposed travel of the vehicle.
Propeller - CORRECT ANSWER-Produces a moderate increase in velocity for a
relatively large mass of air.
Jet Engine - CORRECT ANSWER-Produces a much higher increase in velocity
for a smaller mass of air.
Rocket - CORRECT ANSWER-Produces an enormous increase in velocity for a
small quantity of gas.
Engine Efficiency - CORRECT ANSWER-The performance of the aircraft
increases if the specific weight of an engine is decreased.
, Reciprocating Engines - CORRECT ANSWER-Produce approximately 1 HP for
each pound of weight.
Specific Fuel Consumption - CORRECT ANSWER-The fuel flow divided by
brake horsepower, describing the fuel economy of aircraft engines.
Durability - CORRECT ANSWER-The amount of engine life obtained while
maintaining the desired reliability.
Reliability - CORRECT ANSWER-Determined by maintenance, overhaul, and
operating personnel.
Operating Flexibility - CORRECT ANSWER-The ability of an engine to run
smoothly and give desired performance at all speeds from idling to full-power.
Compactness - CORRECT ANSWER-The shape and size of the engine must be
compact for proper streamlining and balancing of an aircraft.
Piston Engine - CORRECT ANSWER-The usual choice for aircraft whose
cruising speeds will not exceed 250 MPH, chosen for its excellent efficiency.
Turbocharged Engine - CORRECT ANSWER-A piston engine modified for high
altitude use using exhaust.
Supercharged Engine - CORRECT ANSWER-A piston engine modified for high
altitude use using an accessory drive.
