Unmanned aerial vehicle vehicle-mounted test lift force measurement restraint device, use method and measurement method

Abstract

The invention discloses an unmanned aerial vehicle vehicle-mounted test lift force measurement restraint device, a use method and a measurement method, and relates to the technical field of unmanned machinery, and the device comprises a base, a force measurement tray, a force measurement sensor, an aircraft wheel clamp, a hoop and a fastening reinforcement member. The application method of the device comprises the following steps: detaching the wheel clamp, and pushing the unmanned aerial vehicle onto the force measuring tray; the airplane wheel clamp is reinstalled on the force measuring tray to clamp the airplane wheel; the hoop is fixed, and the hoop and the airplane wheel clamp are connected through a fastening reinforcing piece; the measurement method comprises the following steps: fixing an undercarriage of a to-be-measured unmanned aerial vehicle on the device; a measuring sensor is used for measuring the lift force, and the whole-aircraft pitching moment M generated by the lift force is solved based on the lift force of the nose landing gear and the main landing gear. The problem that the reaction force of the unmanned aerial vehicle cannot be accurately measured in a vehicle-mounted test is solved, and meanwhile, the safety of the unmanned aerial vehicle is guaranteed when the unmanned aerial vehicle encounters dangerous conditions such as gust.
