Title:
LIGHTWEIGHT SMALL FLIGHT VEHICLE
Document Type and Number:
WIPO Patent Application WO/2015/049798
Kind Code:
A1
Abstract:
A lightweight small flight vehicle (1) that flies by rotation of a rotor (2) is characterized by being equipped with: a rotation prevention blade (5) that generates a torque about a main shaft (100) in a fuselage (10) by receiving by a blade surface (5a) an airflow that is generated in the axial direction of the main shaft (100) by the rotation of the rotor (2) in order to reduce a reaction torque that is generated in the fuselage (10) as a counteraction to the rotation of the rotor (2), the tilt angle of said blade surface being changeable with respect to the axial direction of the main shaft (100); and a control device (23) that changes the tilt angle of the blade surface (5a) in order to adjust the magnitude of the torque to be generated about the main shaft (100) in the fuselage (10).
