Description
Technical field
The utility model belongs to seaplane, hydrofoil field more particularly to a kind of air foil profile seaplane.
Background technique
Seaplane is a kind of aircraft that can be realized water surface landing.Currently, seaplane is sliding in order to realize the water surface
Row, usual fuselage bottom design have faulted-stage type hull, to reduce large drag forces when hydroplaning, while enhancing seaplane water
The stability of face movement.
But huge hydrodynamic resistance, water are still suffered from using the seaplane of faulted-stage type hull design in the prior art
Engine required horsepower also increases with it when the water surface of boarding a plane takes off, and in the sky when flight, engine required horsepower compares the water surface
It is substantially reduced when sliding, is easy to cause engine power to mismatch in this way, while the weight for increasing engine reduces aircraft
Payload.
Therefore, traditional seaplane has the disadvantage that resistance is larger when 1. waters surface take off；2. traditional seaplane starts
Machine power mismatches, and causes dynamical system weight bigger than normal；3. traditional seaplane can not be grown due to above-mentioned defect
Time is in hydroplaning.
Utility model content
The utility model is directed to above-mentioned problems of the prior art, discloses a kind of air foil profile seaplane, this reality
Both seaplane, hydrofoils characteristic is combined with novel seaplane, hydrofoil unit, air foil profile are set on aircraft on the water
For seaplane in hydroplaning, fuselage can be lifted away from the water surface without contacting with the water surface, to reduce by the lift that hydrofoil generates
The Area of Wetted Surface of complete machine reduces resistance, can be realized seaplane surface motions drag reduction and the quick motor function of the water surface, solves
The defect of the prior art.
The utility model is realized in this way:
A kind of air foil profile seaplane, including fuselage, the wing at left and right sides of fuselage, in fuselage lower end in the utility model
It is provided with hydrofoil unit, hydrofoil unit includes preceding hydrofoil and rear hydrofoil；Preceding hydrofoil is located at the front of fuselage lower end, and rear hydrofoil is located at
The tail portion of fuselage lower end；Preceding hydrofoil and rear hydrofoil are horizontal by 45 ° of angles.When aircraft takes off in hydroplaning or the water surface
When, preceding hydrofoil and rear hydrofoil cut face generation hydrodynamic lift of striking and fuselage are lifted away from the water surface, to reduce the Area of Wetted Surface of complete machine
Reduce resistance.
Afterbody is provided with T-type empennage, the transverse and longitudinal stability of the adjustable aircraft of T-type empennage, while winged to control
Pitching, rolling and the yawing rotation of machine.T-type empennage includes horizontal tail, vertical fin, rudder and pitching rudder, and the vertical fin is located at machine
Body tail portion upper end, horizontal tail are located at vertical fin upper end；The rudder is located at vertical fin rear；The pitching rudder is located in horizontal tail
Side；The wing both ends are provided with airscrew engine, and airscrew engine provides power for aircraft.
Further, the preceding hydrofoil and rear hydrofoil use SIMPLE7 aerofoil profile, which is conducive to preceding hydrofoil and rear water
The wing generates smaller wave when the water surface works.
Further, lower section is separately installed with left floating drum and right floating drum in the middle part of two wings, is symmetrical with face in fuselage
Face is symmetrical.Left floating drum and right floating drum can enhance stability of the air foil profile seaplane in floating on water.
Further, port aileron and starboard aileron are respectively arranged at rear above two wings of the left and right.
The beneficial effect of the utility model and the prior art is:
1) compared with traditional seaplane, the hydrodynamic(al) reduced when the water surface takes off by installing hydrofoil unit additional hinders the utility model
Power；The principle that hydrofoil generates lift is consistent with wing, but the density of water is about 800 times of air, therefore lesser hydrofoil soaks
Area can generate larger hydrodynamic lift；Air foil profile seaplane can rely on hydrofoil in hydroplaning as foilcraft
Fuselage is lifted away from the water surface without contacting with the water surface by the lift of generation, so that the Area of Wetted Surface for reducing complete machine reduces resistance, drop
The low required horsepower of engine, therefore the lighter engine of weight can be selected compared with traditional seaplane, improve complete machine
Performance；
2) the surface motions ability for the fast and flexible that the utility model makes seaplane have foilcraft the same, suffered water
Dynamic resistance greatly reduces, and engine required horsepower reduces, therefore can be lighter using weight compared to same seaplane
Engine, to improve the payload of seaplane, the utility model carrier has both the spy of seaplane, foilcraft
Property；
3) at military aspect, air foil profile seaplane relies on its quick surface motions ability and landing ability waterborne, can
Execute water life-saving, it is antisubmarine, investigation and with naval vessels prompt strike capabilities；Air foil profile seaplane is because suffered hydrodynamic resistance is small, energy
The flight of long period is enough carried out in the water surface, it is possible to which sea surprise attack operation is plunderred in execution；
4) at civilian aspect, air foil profile seaplane has both the function of seaplane and foilcraft, is suitable for cruise,
Communications and transportation and flight experience, applied widely between island.
