Ch 4 - Aerodynamic Force Flashcards
1
Q
Total Pressure =
A
= Static Pressure + Dynamic Pressure
= Static Pressure + 1/2rhoV^2
2
Q
Aerodynamic Force =
A
= Pressure x Area
3
Q

A
Has:
- Viscosity
- Compressibility
In the real world
4
Q

6
Q
Aerodynamic Force =
A
= Pressure x Area
Total reaction goes through the Centre of Pressure
- > Lift
- > Drag
