The expansion and contraction axial flight stable

摘要

PROBLEM TO BE SOLVED: To provide a flight machine capable of attaining a stable flight during a low-speed flight when taking off and landing, and reducing air resistance during a usual flight.;SOLUTION: A wing and a trunk being a main body are bonded by a joint which can turn with two axes perpendicular to each other as a center, a drive device which is arbitrarily turned with the two axes as a center, respectively, is provided, and thereby a roll angle and a pitch angle of the wing can be arbitrarily changed. In such a flight machine, the wing and the flunk are connected to a stretching/contraction mechanism capable of being set to an arbitrary distance. The stretching/contraction mechanism is formed as a fixed wing structure so that it is not turned by the joint by enhancing pendulum stability by being elongated to the longest length at the low-speed flight including taking-off and landing, and reducing air resistance by being contracted to the shortest length at a high-speed flight. At that time, flight control by an auxiliary wing such as an aileron provided on the wing is also performed. Furthermore, the joint is made to be a joint capable of being controlled by three axes capable of also arbitrarily changing a yaw angle, and when the wing is directed to a windward side of a lateral wind, the trunk can be directed to a flight direction.;COPYRIGHT: (C)2010,JPO&INPIT
