Some excellent works such as sherpa in germany, phase-II in cosmos in france, XT912, XT582 in airborne in australia, etc. have appeared abroad, and the domestic initiative is late, but some good works such as FY450, FY550 have also appeared.

The power delta wing comprises a delta wing, a fuselage, a landing gear and a power device. The power delta wing holds two persons, and usually provides power by a piston type aero-engine, so that a propeller is driven to propel the aircraft forwards. The fuselage is suspended under the delta wing through the hinge, and the pilot realizes the balance and the flight of aircraft through controlling the removal to relative focus position of both.

Compared with the conventional low-altitude sports small aircraft, the dynamic delta wing has the advantages of simple structure, low cost, excellent performance and wide application field, and is mainly embodied in the following aspects:

(1) compared with rotor aircrafts such as autorotation gyroplanes and the like, only one propelling propeller is needed to be installed at the tail end of the aircraft body, and a special reaction torque paddle is not needed, so that the flight safety is high;

(2) compared with a light small aircraft with fixed wings, the take-off and landing running distance is short, the flight stability is good, and the low-speed performance of a medium-low altitude is good;

(3) the structure is light, the manufacture and the control are simple, the disassembly is convenient, the triangular wings are foldable, the transportation and the maintenance are easy, the cost is low, the safety is good, and the like.

The existing power delta wing has the following defects: the piston type aircraft engine is adopted to provide power, so that the propeller is driven to propel the aircraft forwards, the engine is complex in structure and heavy in weight, and the engine is installed at the tail of the delta wing, so that the improvement of the weight balancing and the stability of the whole aircraft is not facilitated.
