Propulsion system for airplanes

What is a propulsion system?

• a machine that produces thrust

• A part of the airplane

• To push something forward

Purposes of propulsion system

• Add better aerodynamic

• Thrust must exceed the drag force of the airplane

• save energy and fuel

Purposes of the propulsion system

• Keep the airplane on balance when it is crusing

• Save energy and fuel

• Better efficiency into airplane

With what Newton's Law does the Jet turbine works?

• 1st Law

• 2nd Law

• 3rd Law

• None of them

In which part of the jet turbine the air gets an enormous expansion?

• Compressor

• Combustion Chamber

• Turbine

• Nozzle

Truth or false?

The air lost energy when it goes through the turbine in a jet turbine

• False

• Truth

In what part of the turbine the air enters?

• Point of exhaust

• Intake

• Compressor

• Electric generator

Some of the advantages of the propeller turbines are:

• Can accelerate a large amount of air

• Requires longer runways

• Long range

• The runway must be of concret

Are components of the propeller turbines

• Turbines and pistons

• Gearbox, propeller and turbines

• Propeller, turbines and pistons

• Air, gas, mix of both

These are advantages of piston turbines, except:

• Cost-effectiveness

• Simplicity

• Velocity

• Fuel-efficiency
