Flashcards

Helix path

The path traced by a propeller blade as it rotates and moves forward.

Rudder

A flight control surface used to control the aircraft's yaw (horizontal turning movement).

Thrust

The force generated by a propeller that propels an aircraft forward.

Ailerons

Control surfaces located on the trailing edge of the wings, used to control roll.

Study Notes

Aircraft Components and Controls

  • The path of a propeller blade is called the helix angle.

Flight Controls

  • The rudder is the flight control that helps the plane yaw.

Propellers

  • Lift on propellers is known as thrust.

Aircraft Wings

  • Ailerons are located on the trailing edge of an aircraft wing.
  • The angle of attack is the angle between the wing and the oncoming airflow.
  • A dihedral wing structure provides greater stability and roll rates by increasing the distance between the left and right wings.
  • Anhedral wings are downward-sloping, often seen in high-performance or aerobatic aircraft.
  • The three main internal structure components of a wing are spars, ribs, and stringers.
  • The ribs of a wing are found internal to the wing, providing structural support and shape.

Primary Flight Controls

  • The primary flight controls of an aircraft are ailerons, elevators, and rudder.
