Aircraft Engine Placement and Types

Most aircraft generate lift/thrust relying on Newton's third law of motion, which states:

• A body in rest or motion will remain at rest or motion until acted upon by an external force

• For every action there is an equal and opposite reaction

• Force is equal to mass times acceleration

• Torque is measured as a force measured by a radial distance

The main types of propulsion systems include: Propellers, __________________, Ramjets, and Rockets

• Gas Turbine

• Radial Engines

• Turbocompressors

• Inertial Engines

True or False: Diesel engines are commonly used on aircraft.

• True

• False

A two-stroke engine will be more powerful and lighter than a four stroke at the cost of:

• More pollution

• More noise

• More fuel consumption

• All of the above

All internal combustion engines operate in four stages: intake, _____________, combustion, and exhaust

Compared to two-stroke engines, four stroke engines are quieter and ______________________

Name the four types of gas turbine engines

What are the main components of a gas turbine?

• Inlet

  Compressor

  Shaft

  Burner

  Turbine

  Nozzle

• Intake

  Shaft

  Exhaust

  Piston

  Afterburner

• Cylinder

  Fan

  Intake

  Sparkplug

  Valves

• Intake

  Shaft

  Turbine

  Nose Cone

  Flaps

The two categories of gas turbine engines are

• Thrust Producing and Shaft Power

• Induction and Convection

• Reciprocating and Diesel

• Mechanical and Electric

The amount of air that does not go into the compressor of the jet engine but instead goes around it is measured as the:

• Bypass Ratio

• Fuel Efficiency

• Compression Ratio

• Gastric Bypass
