Aerofoil Pressure Distribution
1
Q
What happen to the dynamic pressure if speed es doubled?
A
Dynamic pressure will be 4 times larger.
2
Q
On a CAMBERED aerofoil, what happen to the total reaction and the centre of pressure (CP) if the angle of attack (AoA) is increased?
A
The magnitude of the total pressure would increase and the CP would move forwards.
3
Q
On a SYMMETRICAL aerofoil, what happen to the total reaction and the centre of pressure (CP) if the angle of attack (AoA) is increased?
A
The magnitude of the total pressure would increase and the CP would NOT move.
4
Q
What happen if the camber increase?
A
The pressure between the upper and lower surfaces would change.
