Abstract
PURPOSE: To achieve shortening of a landing run distance by composing a flap of an aircraft to be operated upward automatically or manually after grounding at the time of landing for generating negative lift downward to improve braking effect by friction with a road surface. CONSTITUTION: An aircraft comprises main wings 1, flaps 3', and legs 11. In this case, the flap 3' is composed in such a way that it can be operated more upward than a neutral position. A flap actuation operation device 12 is mounted on an airframe for determining if the aircraft is grounded or not, determining if upward operation of the flap 3' is to be conducted automatically or manually, giving drive command for the flap 3', etc. When the aircraft is running at a specified speed V after landing, the flap 3' is operated upward to generate negative lift L downward. A large friction is thus generated between the aircraft and a road surface, so aircraft braking effect is improved. Landing run distance can thus be shortened.
