VERTICAL TAKEOFF AND LANDING FLIGHT VEHICLE WITH FOREIGN MATTER REMOVAL MOVABLE PART

摘要

To reduce an accident during flight such that a vertical takeoff and landing flight vehicle, which flies in the sky, collides a foreign object such as birds or the like.SOLUTION: A propeller 4 and an engine for rotating the propeller are located in a frame 2 of a thruster which generates lift and thrust in a vertical direction of a vertical takeoff and landing flight vehicle. The frame of the thruster has such a structure that a foreign matter entry prevention member 5 is located on an air intake port 3 which is formed in a round cylindrical shape. An edge 5d of the foreign matter entry prevention member is held by a guide rail 2a provided at an upper part of the frame of the thruster. One to several auxiliary wings 5c are provided on the foreign matter entry prevention member. A net is stretched over the foreign matter entry prevention member, a foreign matter, which is pulled into the air inlet port 3 by a suction force from above, is stopped by the foreign matter entry prevention member, and the foreign matter entry prevention member is rotated as a foreign matter removal movable part 6 by air current hitting on the auxiliary wings, thereby shaking off the foreign matter.SELECTED DRAWING: Figure 1
