Lift & Drag Devices
- Lift Devices
- Hinged/pivoted or sliding profiles near trailing edge
- Mainly used for landing to increase lift and drag
- Used for take-off on large aircraft to increase lift
- Plain Flap
- Looks like a control surface
- Flaps on two wings linked, move down together
- 55% lift increase
- Looks like a control surface
- Split Edge Flap
- 65% lift increase
- Flat metal plate which is hinged along its forward edge
- 65% lift increase
- Slotted Flap
- 70% lift increase
- Allows air from lower side of wing to upper side
- Helps prevent early flow seperation
- Helps prevent early flow seperation
- 70% lift increase
- Fowler Flap
- 95% lift increase
- Rolls bac on a track when extended
- Increases effective wing area and lowers trailing edge
- Fits into lower contour of trailing edge when retracted
- 95% lift increase
- Slat
- Moveable leading edge of the wing
- Forms a slot when extended
- 35% lift increase
- Moveable leading edge of the wing
- Hinged/pivoted or sliding profiles near trailing edge
- Drag Devices
- Spoilers
- Located on upper surface of the wing close to the trailing edge
- Increases drag
- Reduces lift
- Located on upper surface of the wing close to the trailing edge
- Air Brakes
- Located in areas where structure is strong enough to withstand heavy air-loads
- Some civil aircraft, tail cone is separated to increase total drag without affecting lift
- Some military aircraft, located on the upper surface
- Some aircraft located on the left and right sidewalls
- Located in areas where structure is strong enough to withstand heavy air-loads
- Spoilers
