(2) fuselage interior of the present invention in aircraft front end installs lift fan, jointly forms bikini power arrangement, for aircraft provides stable lift with rear portion vectored thrust device.Described vectored thrust mechanism, without external screw propeller, enables aircraft among a small circle, realize vertically/short take-off and landing (STOL), and can realize aerial low speed cruise and hover and aerial efficient vector motor-driven;
(3) the Moving mechanism in the present invention can change centroid position under different flight state, for aircraft promotes airworthiness and stability, makes flying instrument for multi-pose flight performance;
(4) wing machine rotary folding system in the present invention is by wing by the system folding under different demand of fold mechanism, thus can reduce the storage space of aircraft, convenient transport and throwing in, and aircraft can be made to cruise in small space cruise.

Detailed description of the invention:
See accompanying drawing 1,3, based on Moving technology can floating type folded wing lifting body aircraft, it comprises: lifting body fuselage 1, after two that are connected with lifting body fuselage 1 41, two, front wings, wing 42 adopts blended wing-body formula tandem wing layout, and aircraft also comprises: Moving mechanism 2, vectored thrust mechanism 3 and wing rotary folding mechanism 4;
The fuselage of lifting body fuselage 1 for providing lift for aircraft is overall during a kind of flight, can reduce wing area by actv. like this, and make aircraft still have superior aerial cruising ability;
After two 41, two, front wings, wing 42 adopts blended wing-body formula tandem wing layout to be: front wing 41, wing 42 share the aerodynamic arrangement of lift before and after apportion between two jointly; This layout can make the span of wing reduce, and makes aircraft more flexibly small and exquisite;
