Controls And Their Effects

Question 1

When the pitch horn is attached to the trailing edge of the blade , raising the collective will cause the swash plate to (rise, fall) so that the blade angle will (increase, decrease)

Answer 1

Fall
Increase

Question 2

Using collective (will, will not) effect the amount of total rotor thrust and it (will , will not) change the orientation of total rotor thrust.

Answer 2

Will
Will not

Question 3

Moving the cyclic control (will, will not) raise or lower the swash plate but it will ——- the swash plate so that ( all blades together, individual blades) obtain changes to their (blade angle, angle of attack)

Answer 3

Will not
Tilt
Individual blades
Blade angle

Question 4

Cyclic and collective controls activate the ——- plate (or star) of the swash plate and control inputs are transferred to the blades via the ——- plate (or star)

Answer 4

Stationary
Rotating

Question 5

The function of a correlator unit is to (increase, decrease) engine power as te collective is raised. As altitude is gained the correlater unit becomes(more, less) effective.

Answer 5

Increase
Less

Question 6

When a blade flaps up , the centre of gravity moves (in towards, out from) the axis of rotation and as the blades (increase, decrease) its speed it will move (forward, rearward) on its lead lag hinge. This is known as ——- effect.

Answer 6

In towards
Increase
Forward
Coriolis

Question 7

Periodic drag changes occur in forward flight when (blade angle, angle off attack) change because of blade flapping.

Answer 7

Angle of attack
