AGK - Essential Physics Flashcards
1
Q
How do internal combustion engines generate thrust?
A
They burn fuel with air to generate thrust.
2
Q
How do piston engines turn a propeller?
A
Piston engines combust gas to generate pressure which turns the propeller.
3
Q
How do gas turbine engines work?
A
They combust gas to turn a fan rearwards at high speed.
4
Q
What is the formula for thrust?
A
F = M x (Vjet - Vflight)
Vjet = Speed of the air exiting the turbines.
Vflight = Speed of the air.
5
Q
What does torque depend on?
A
- The force applied.
- The length of the lever arm connecting the axis.
- The angle between the two.
6
Q
What is the formula for power?
A
Power = force x speed
