Common UAS Configuration- Rotary Wing Flight

Lift is generated from a rotating wing called a rotor. A motor or engine drives a rotor through the air in a circular motion and if the RPM of the rotor and the AOA of the rotor blades are at the proper angle, the rotor produces lift. 

3

Multiple Select

Select two advantages of a rotary-wing UAS.

1

They are capable of VTOL and hovering flight operations

2

They can perform aerial tasks in where is limited space for takeoff and landing operations

3

They have a longer flight and on- station mission duration

4

They require less energy than fixed-wing aircraft

4

Rotary-wing aircraft must have at least two rotors to provide stability and control and fall into two categories.

5

Multiple Select

Which are the two categories of rotary-wing aircraft?

1

Helicopters

2

Multi-rotor

3

Fixed-wing

4

VTOL

6

Helicopters generally have a single primary lifting rotor and two or more blades where the AOA of each can be controlled individually or collectively. 

7

Multiple Select

Select two disadvantages of helicopters.

1

Not capable of carrying heavy payloads

2

Power required by the rotor to counteract the torque of the main rotor makes it less efficient than rotary-wing UAS

3

The main rotor blade moves very fast and creates a hazard

8

To increase the payload capacity of a multirotor vehicle, an even number of rotors that alternate in direction can be added to the arms of the vehicle. 

9

Multiple Choice

How do these additional rotors help in the event of a motor/rotor failure?

1

They add a level of propulsion and vehicle redundancy

2

They allow the vehicle to fly higher and avoid crashing into objects

3

The enable the vehicle to return to home quickly

10


A tri-copter is a multi-rotor with only three sets of lifting rotors. Movement is generated by a tail rotor that pivots laterally and uses a servo to change the lift vector to control the yaw axis of the vehicle. 

11

Multiple Choice

Why are tri-copters less efficient than multi-rotor vehicles with an even number of rotors?

1

Because they have to use special power systems.

2

Because they have to use a vectored thrust to control yaw.

3

Tri-copters and multi-rotor vehicles with an even number of rotors are equally efficient.
