1
Q

A
The cross section of a wing. The point of maximum thickness of an aerofoil usually occurs in the first 1/3 of the chord length
2
Q
Bernoullis theorem
A
In a flow of an ideal fluid, the sim of pressure and Kinetic energy (per unit volume) remains constant.
3
Q
Ideal fluid
A
It is incompressible.
It has no viscosity.
4
Q
Pathlines
A
Show the individual trajectories of small volumes of air.
5
Q
Stream tube
A
A volume of air bounded by streamlines
6
Q
What is the coanda effect
A
When air encounters a smooth surface it will attach. It will only attach if the angle of the surface is very small
7
Q
What is the stagnation point
A
The area on the wing where the air is stationary
