Lift (Chapter 6)

Question 1

AoA - increase

Coefficient of Climb - increase

Answer 1

Thickness of aerofoil. As the thickness of the aerofoil increases, so does the coefficient of lift as well as the angle of attack, before it can stall (Critical angle)

Question 2

AoA - Constant

Coefficient of Climb - Increase

Answer 2

Camber of an aerofoil. As the camber is increased in a positive manner, the coefficient of lift is increased but the critical angle remains the same.

Question 3

AoA - Decreases

Coefficient of Lift - Increase

Answer 3

This is the addition of a trailing flap. The increase in the camber creates a larger coefficient of lift but a smaller critical angle

Question 4

Point of stall also known as…(instead of AoA)

Answer 4

Critical angle

Question 5

Coefficient of lift…

Answer 5

Is a dimensionless number which shows how natural an aerofoil is at being able to produce lift.

Question 6

Cambered aerofoil producing a greater AoA and a greater coefficient of lift

Answer 6

Low speed aerofoil

Question 7

An aerofoil producing a smaller AoA and smaller coefficient of lift…

Answer 7

High speed aerofoil
