Aircraft

Abstract

The invention provides an aircraft. The aircraft comprises a passenger compartment and a bottom compartment, wherein the bottom compartment is of an opened box structure and comprises a driving deviceand one group of mechanical arm assemblies or more; each mechanical arm assembly comprises two swinging arms, the two swinging arms form an adjustable included angle through a rotary mechanism, propellers are respectively arranged at one end, corresponding to the included angle, of each of the two swinging arms, and the propellers are extended and retracted into the bottom compartment along withthe swinging arms by adjusting the included angle; the driving device adopts motors, the motors comprise a first motor and a second motor, the first motor is used for driving the rotary mechanism, andthe second motor is used for driving the propellers. By adopting the technical scheme, the aircraft has the advantages that the structure is simple, and the operation is easy; the propellers are extended and retracted into the bottom compartment, so that the size of the whole aircraft is smaller, the aircraft is more flexible, and the accident risk due to collision of the propellers during low-altitude flight is reduced.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to an aircraft capable of flying at low altitude. Background technique [0002] With the development of society, people have higher and higher requirements for means of transportation, and the demand for low-altitude aircraft is even stronger. At present, in the field of low-altitude manned aircraft, helicopters are the most common, and they can fly at relatively low altitude and low speed. Since the helicopter has a single-rotor with tail rotor layout, but the tail beam leads to a large parking area, the carried tail beam and the long-distance tail rotor drive shaft are easily damaged, the risk of collision is high, and the hovering performance is unstable. The aircraft is disclosed, especially the quadcopter with mature technology, which can even fly close to the ground. The four rotors are separately driven by four motors. The operation is simple, small and flexible, but the rot...

Problems solved by technology

[0002] With the development of society, people have higher and higher requirements for means of transportation, and the demand for low-altitude aircraft is more intense. At present, in the field of low-altitude manned aircraft, helicopters are the most common, and they can fly at relatively low altitudes and low speeds, but Since the helicopter has a single-rotor with tail rotor layout, but the tail boom leads to a large parking area, the carrying tail boom and the long-distance tail rotor drive shaft are easily damaged, the risk of collision is high, and the hovering performance is unstable. The aircraft is disclosed, especially the quadcopter with mature technology, which can even fly close to the ground. The four rotors are separately driven by four motors, which is simple to operate, small and flexible, but the rotor of the quadcopter is fixed. The bottom surface will also occupy a relatively large area when flying, which is easy to collide and cause traffic accidents
