Principles of flight_chapter_6

  1. 1. Principles of Flight Chapter 6 – Helicopters
  2. 2. Introduction <ul><li>A helicopter generates both lift and thrust by using its rotor blades rather than wings. </li></ul><ul><li>Blades are just wings which spin round on a central axis. </li></ul>
  3. 3. Lift <ul><li>To generate more lift the blades must be pitched to increase the angle of attack. </li></ul><ul><li>Pilots control known as the Collective pitch control. </li></ul>
  4. 4. Horizontal Flight <ul><li>The thrust is provided by tilting the disc in the direction required </li></ul><ul><li>Pilots control called cyclic pitch control or stick. </li></ul>
  5. 5. Horizontal Flight <ul><li>The thrust is provided by tilting the disc in the direction required </li></ul><ul><li>Pilots control called cyclic pitch control or stick. </li></ul>
  6. 6. Horizontal Flight <ul><li>The thrust is provided by tilting the disc in the direction required </li></ul><ul><li>Pilots control called cyclic pitch control or stick. </li></ul>
  7. 7. Horizontal Flight <ul><li>The thrust is provided by tilting the disc in the direction required </li></ul><ul><li>Pilots control called cyclic pitch control or stick. </li></ul>
  8. 8. Torque Reaction <ul><li>Is the force that tries to make the fuselage spin in the same direction as the blades. </li></ul><ul><li>Counteracted by using a tail rotor to push the fuselage in the opposite direction. </li></ul><ul><li>By altering the pitch of the tail rotor blades it can yaw the aircraft. </li></ul><ul><li>Helicopters with 2 blades – each rotor spins in different directions. </li></ul>
  9. 9. Torque Reaction
  10. 10. Torque Reaction
  11. 11. Controls <ul><li>4 Controls </li></ul><ul><li>Collective Pitch – On left hand side, pulls up to increase lift and vice versa. </li></ul><ul><li>Hand Throttle – On the collective pitch stick, twists to give more power to rotor. </li></ul><ul><li>Cyclic Pitch – Stick between legs, left to go left, forward to go forward etc. </li></ul><ul><li>Tail Rotor - Feet Pedals, Right to yaw right and vice versa. </li></ul>
