Tracking On The Table Flashcards
1
Q
What is effective pitch?
A
The effective pitch is the actual distance a propeller advances through the air in one revolution. Affected by forward velocity of airplane.
2
Q
Geometric pitch
A
The theoretical distance a propeller advances through the air in one revolution.
Geometric pitch = Tan–1 pitch angle · 2π · r
3
Q
What is slip?
A
The difference between geometric pitch and effective pitch
4
Q
How does a propeller produce thrust?
A
By momentum theory
5
Q
What is the propeller tracking
A
The path that the tip of the blade follows when the propeller rotates while aircraft is stationary.
