10 Questions
What effect does using flaps have on the lift coefficient (CL) and drag coefficient (CD)?
Increases CL and CD
In a constant altitude coordinated banked turn, what is the relationship between the bank angle and the speed of the aircraft?
Bank angle and speed are inversely related
Which statement accurately describes an aerofoil with zero camber?
It produces lift at all angles of attack
How do Bernoulli's principle and fluid dynamics relate to the relationship between speed and pressure along a streamline?
Speed increase is associated with pressure decrease
What are the aerodynamic characteristics of the aircraft in clean configuration based on the provided information?
CL increases linearly with αS
For an aerobatics airplane flying in balanced straight and level flight at V = 50m/s with α = 1°, what should the speed (Vif) be to perform balanced inverted flight at the same altitude and α = -1°?
Vif = 61.3 m/s.
In calculating the stall speed of an airplane with CL = 0.2 + 0.2α and given parameters, what is the stall speed (VS) for an airplane of mass 1200 kg and wing surface 8m²?
VS = 31.3 m/s.
