A ground-air amphibious search and rescue flying vehicle

Abstract

The invention discloses a flying car. The flying car comprises a car body, a parafoil for supplying flying lift, and a power switching device for switching land and air; a propeller is mounted at the tail part of the car body for supplying power for air flight; the parafoil includes a canopy, and a parachute cord for realizing the force traction between the car body and the canopy; a power device is an engine arranged at the head part of the car body; and the power switching device finishes the output switching of a rear wheel transmission shaft and a rear wheel and the propeller in the car body. An air-ground amphibious flying car is realized according to the invention, is simple in structure, and is efficient and quick in working mode switching; the switching of ground and air working modes only needs a short period of time; the mutual switching between the two modes can be finished within about 10 minutes; and an air-ground amphibious search and rescue platform driving technology is simple, easy-learnt, safe, reliable and low in controller training cost.

Description

technical field [0001] The invention belongs to the field of search and rescue, and more specifically relates to a land-air amphibious search and rescue aircraft. Background technique [0002] After natural disasters or accidents, it is necessary to carry out emergency rescue to the disaster-stricken area or the area where the accident occurred, while ground search and rescue vehicles can only drive on road conditions such as roads, and the area to be rescued is often difficult for motor vehicles to reach directly, and the field of view of ground search and rescue The search and rescue efficiency is low, and it is often difficult to cross road obstacles due to road damage and congestion in the area to be rescued; while the air search and rescue has the characteristics of fast arrival and high search efficiency, but is limited by the landing field and cannot be launched at will. Therefore, there is a need for a vehicle that can operate on the ground and can be changed to a fl...

Problems solved by technology

[0002] After natural disasters or accidents, it is necessary to carry out emergency rescue to the disaster-stricken area or the area where the accident occurred, while ground search and rescue vehicles can only drive on road conditions such as roads, and the area to be rescued is often difficult for motor vehicles to reach directly, and the field of view of ground search and rescue The search and rescue efficiency is low, and it is often difficult to cross road obstacles due to road damage and congestion in the area to be rescued; while the air search and rescue has the characteristics of fast arrival and high search efficiency, but is limited by the landing field and cannot be launched at will. Therefore, there is a need for a vehicle that can operate on the ground and can be changed to a flight mode when encountering a roadblock, so as to overcome obstacles by flying, and there are some flying cars in the prior art, but these The main function of the flying car is to be used as a means of transportation for the flying car, and most of them use folding wings and propellers as the power of the flight to fly, which will cause the shortcomings of the heavy weight of the aircraft and the complexity of the power system required, which leads to the application In search and rescue, it is not possible to flexibly switch between ground and air modes, so it is extremely necessary to design an amphibious aircraft that can flexibly switch between modes
