Rotary Wing Quadcopter Theory

What is the opposing force experienced by a motor/engine when it spins a rotor?

• Thrust

• Torque

• Reaction torque

• Hover

How can the torque effect be overcome in a quadcopter?

• By increasing the speed of all 4 rotors

• By decreasing the speed of all 4 rotors

• By placing rotors spinning in the same direction diagonally apart

• By using a tail rotor

Which action is achieved by increasing the speed of the 2 rotors facing the intended direction of movement?

• Roll

• Pitch

• Yaw

• Hover

What is the purpose of the tail rotor in a helicopter?

• To generate lift

• To provide stability

• To counterbalance the torque effect

• To control the pitch

Which axis of flight motion is responsible for rotation about the lateral axis?

• Roll

• Pitch

• Yaw

• Hover

How can rolling be achieved in a quadcopter?

• By increasing the speed of the 2 rotors facing the intended direction of movement

• By decreasing the speed of the 2 rotors facing the intended direction of movement

• By increasing the speed of the remaining 2 rotors

• By decreasing the speed of the remaining 2 rotors

Which action is achieved by decreasing the speed of the 2 rotors facing the intended direction of movement?

• Roll

• Pitch

• Yaw

• Hover

Which axis of flight motion is responsible for rotation about the longitudinal axis?

• Roll

• Pitch

• Yaw

• Hover

What is the purpose of the rotor in a helicopter?

• To generate lift

• To provide stability

• To generate torque effect

• To control the pitch

Which axis of flight motion is responsible for rotation about the vertical axis?

• Roll

• Pitch

• Yaw

• Hover
