Utilize the rotating electrical machines drive to rotate the baffle and carry out turnover motion, when the notch on rotating the baffle aligns with the jet orifice 1 on the cylinder block on certain direction, compressed high-pressure gas can be followed jet orifice 1 and discharged to realize the change of aircraft in aerial direction.

Preferably, the shape of the cylinder body is a disc-shaped structure, and the structure can avoid interference of external environments (sundries, branches and the like) to flight in order to realize flight under more working conditions, particularly to flight in a jungle.

Preferably, the piston is arranged in a spoke-shaped structure, the structure is favorable for realizing air suction, and the function of self-separation to close attachment of the piston and the piston cover plate is realized by adopting a purely mechanical structure method.

Preferably, an air jet control valve is arranged at each air jet 2 on the lower surface of the cylinder block, and the discharge amount of high-pressure air can be effectively controlled by controlling the opening size of the air jet control valve.

Compared with the prior art, the vertical take-off and landing jet aircraft without the rotor wings provided by the invention has the following advantages:

(1) powering with compressed high pressure air, rather than fuel jets;

(2) by opening different air jets, a fast steering and a large angle steering, for example 180 ° reversal, can be achieved.

(3) Because no propeller is arranged, the safety of outdoor use is improved, and the durability of the outdoor use is improved;

(4) due to the addition of the air bag device, the buoyancy generated by the air bag in the air is utilized to offset a part of gravity, so that the rapid takeoff can be realized, and the endurance time is longer under the same energy condition;

(5) is suitable for flying in jungles.
