Lift Flashcards
1
Q
what angleof attack will give you 0 lift?
A
-4 aka
2
Q
with symmetrical areofoil what happens to centre of pressure when AoA is increased?
A
centre of pressure does not move.
3
Q
what is the equation for aspect ratio?
A
= span/chord
= span^2/area
4
Q
what does high aspect ratio due to Climax?
A
it increases. Clmax
5
Q
what is a high aspect ratio wing?
A
these are wings which look like glider wings long and thin
6
Q
what affect does high aspect ratio have on symmetrical aerofoils?
A
it has no affect on symmetrical areofoils.
7
Q
what does wing sweep do to cL max?
A
wing sweep lowers CL max but increases the angle of attack that the stall occurs
8
Q
what does High aspect ratio do to critical aoa?
A
decreases critical angle of attack.
