Chapter 5 - Aerofoil Pressure Distribution Flashcards
1
Q
What is the Suction Peak
A
Where the static pressure is at least of the aerofoil
2
Q
Why does a symmetrical aerofoil at 0 degrees create drag?
A
Because of form drag
3
Q
What happens to the CofP and stagnation point on a symmetrical aerofoil at a higher AOA
A
CofP does not move
Stag moves under the aerofoil
4
Q
What happens to the CofP and stagnation point on a cambered aerofoil at a higher AOA
A
CofP moves forward
Stag point moves into the downwash because of upwash
5
Q
The pattern of pressure determines the CofP which two things change it
A
AOA
Camber
not flow speed
6
Q
Equation for aerodynamic Force =
A
F = q S Cf
7
Q
equation for Cf =
A
q S
8
Q
Or pressure wise Cf can be expressed as
A
Dynamic Px
