Abstract

The invention discloses a polyxeny aircraft additionally provided with a hydrofoil, and belongs to the field of aslant-rotation aircrafts, hydrofoils and ducted propellers. A hydrofoil device is installed at the belly part of the lower end of an aircraft body, and a tail part ducted propeller is installed at the tail part of the upper end of the aircraft body; a set of V-shaped empennages are installed at the two sides of the tail part ducted propeller; a left ducted propeller and a right ducted propeller are installed at the upper ends of the ends of left and right aerofoils respectively; floats are symmetrically installed at the lower ends of the aerofoils. According to the polyxeny aircraft, the ducted propellers are utilized for replacing propellers, the performance of the aircraft canbe improved, the left ducted propeller, the right ducted propeller and the tail part ducted propeller can aslant rotate, and vertical take-off and landing of the aircraft on the water surface and theground can be achieved; meanwhile, the hydrofoil device is adopted, so that the aircraft has the quick and flexible water surface movement capability, and has the features of aslant-rotation aircrafts and foilcrafts.

Description

technical field

[0001] The present invention relates to the fields of tilting aircraft, hydrofoils and ducted propellers, in particular to a multi-dwelling aircraft, in particular to a multi-dwelling aircraft equipped with hydrofoils. Background technique

[0002] Multi-living aircraft is an aircraft that can operate on water and in the air at the same time, and can take off and land on water. At present, propellers are generally used as propulsion devices in traditional multi-habiting aircraft, but the efficiency of propellers is low and they are easily disturbed by the outside world. Aircraft cannot realize rapid and flexible changes in motion. In addition, the propellers used in traditional multi-habiting aircraft will generate vortex and backflow phenomena at the tips, resulting in low aerodynamic efficiency. Moreover, most traditional multi-habiting aircraft do not have the ability to take off and land vertically on the water surface, so the scope of application is na...

Embodiment Construction

[0030] In order to make the object, technical solution and effect of the present invention clearer and clearer, the following examples are given to further describe the present invention in detail. It should be pointed out that the specific implementations described here are only used to explain the present invention, not to limit the present invention.

[0031] Such as figure 1 Shown, the polyhedous aircraft of the present invention that installs hydrofoil additionally comprises fuselage 16, the wing 3 on left and right sides of fuselage 16, and left aileron 12 and right aileron are symmetrically installed at the trailing edge place of left and right wing 3 5.

[0032] A hydrofoil device is installed on the abdomen of the lower end of the fuselage 16, and the hydrofoil device includes a group of front hydrofoils 1 and a group of rear hydrofoils 14, and the front hydrofoil 1 is installed on the front part of the fuselage 16 abdomen, so The rear hydrofoil 14 described above i...
