DEVICE ALLOWING AN UNMANNED AIR VEHICLE TO TOW AN UNPOWERED AIRCRAFT, AIRCRAFT PROVIDED WITH THIS TOWING DEVICE AND METHOD ALLOWING AN UNMANNED AIR VEHICLE TO TOW AN UNPOWERED AIRCRAFT

摘要

The invention relates to a safe, polyvalent, economic and fast system for towing an unpowered aircraft. The towing device comprises: - An arm (110) for fastening to an aircraft with a rotating aerofoil, designed to be fastened perpendicularly to the plane of rotation of the rotating aerofoil; and - a traction arm (120) designed to be connected to a traction cable (130) of the unpowered aircraft, and mounted so as to pivot on the fastening arm (110) about a pitch axis (Y) perpendicular to the fastening arm. The towing device comprises: a first sensor (141), the so-called "pitch" sensor, of the angle of rotation of the traction arm about the pitch axis; and a sensor (143) of the traction force applied between the cable and the traction arm.
