FIELD: aircraft engineering.SUBSTANCE: flap dive comprises flaps, carriages, links, levers and translating drives. This device comprises flap turn-and-deflect kinematic systems. Turn system allows flap turn with angular shift relative to aircraft Z axis. Note here that as-extended flap stays at position whereat wing trailing edge is parallel with flap leading edge to make the clearance, invariable over the wing span. Deflect system deflects the flaps through preset angle. Note here that as-developed flap can turn about axis Z in flap weight beam. All displacement of the flap are actuated by the rotation of shaft-hole pair.EFFECT: higher efficiency of takeoff-landing performances, decreased weight and sizes.5 dwg |
