Description
Technical field
The utility model relates to the aircraft that verts, hydrofoil and shrouded propeller fields, more particularly to aircraft of dwelling one kind more,
Specifically refer to a kind of aircraft of dwelling for installing hydrofoil additional more.
Background technique
Aircraft of more dwelling is a kind of aircraft that can while run on the water and in the air, and can be realized the water surface and rise
Drop.Currently, tradition aircraft of dwelling generally use propeller as propulsion device more, but the low efficiency of propeller and it is easy by
External interference, when the water surface takes off, resistance is larger, therefore speed when taking off is slow；Simultaneously because the low efficiency of propeller, tradition
Aircraft of dwelling more can not achieve fast and flexible varying motion.In addition, traditional propellers for dwelling aircraft use can generate more
The vortex and backflow phenomenon of blade tip, cause pneumatic efficiency low.Also, traditional aircraft of dwelling do not have mostly vertical in the water surface more
Landing ability, therefore applicable narrow range.
To sum up, it 1) can take off that can not achieve the water surface long in the water surface although tradition aircraft of dwelling have the disadvantage that more
Time slides；2) suffered resistance is big when the water surface takes off, and takeoff distance is remote；3) do not have VTOL ability.
Utility model content
Aiming at the problems existing in the prior art, the utility model discloses a kind of aircraft of dwelling for installing hydrofoil additional more, originally
Utility model can be improved the performance of aircraft using shrouded propeller substitution propeller, while to fly using hydrofoil unit
Device has the surface motions ability of fast and flexible；The utility model aircraft has both the aircraft that verts, the characteristic of foilcraft, solves
Defect in the prior art.
The utility model is realized in this way:
A kind of aircraft of dwelling installing hydrofoil additional disclosed by the utility model more, including fuselage, the wing at left and right sides of fuselage,
Fuselage lower end abdomen is equipped with hydrofoil unit, and the hydrofoil unit includes hydrofoil after hydrofoil before one group and one group, described
Preceding hydrofoil is installed on the front of belly, and the rear hydrofoil is installed on the tail portion of belly.It dwells when installing hydrofoil additional more
For aircraft in hydroplaning, face generation lift of striking mainly is cut by hydrofoil unit makes fuselage be detached from the water surface, reduces itself and the water surface
Contact area realize that the water surface quickly slides to reduce resistance.
Fuselage upper ends are equipped with tail portion shrouded propeller；The tail portion shrouded propeller two sides are equipped with one group of V
T tail, wing provide lift when carrier airflight.Vee tail is mounted on tail, and the cross of carrier movement can be improved
Longitudinal stability.Left direction rudder, right direction rudder are separately installed at one group of rudder-vator rear；The left and right wing
End upper end is separately installed with left shrouded propeller, right shrouded propeller；The lower end of the left and right wing is symmetrically installed with floating
Cylinder.Floating drum is mounted below airfoil root, and bilateral symmetry is distributed, and stabilization when aircraft water surface floating state can be improved in floating drum
Property.
Left shrouded propeller, right shrouded propeller in the utility model, tail portion shrouded propeller can vert, it can be achieved that water
Face, ground VTOL；In addition, lift and push system are mainly by left shrouded propeller, right shrouded propeller and tail portion duct
Propeller composition.
Further, the preceding hydrofoil and rear hydrofoil use SIMPLE6 aerofoil profile, are conducive to preceding hydrofoil and rear hydrofoil exists
The water surface generates smaller wave when working.
Further, tailplane is also equipped at left and right sides of the afterbody.
Further, port aileron and starboard aileron are symmetrically installed at the rear of the left and right wing.
Further, cabin cover, forward engine room lid after the front end of tail portion shrouded propeller is also sequentially installed with.
Further, the rear cabin cover, forward engine room lid use high pressure resistant glass.
Further, the left shrouded propeller, right shrouded propeller by passing through the machine of first rotating shaft and two sides respectively
The wing is connected, meanwhile, left shrouded propeller, right shrouded propeller are rotated around first rotating shaft central axes.
Further, the tail portion shrouded propeller is connected by the second shaft with fuselage, meanwhile, tail portion shrouded propeller
It is rotated around the second shaft central axes.
The beneficial effect of the utility model and the prior art is:
1) the utility model can be improved the performance of aircraft, and the duct spiral using shrouded propeller substitution propeller
Paddle is tilting duct propeller, the advantage is that duct plays preferable protective effect to the blade tip of propeller, it is suppressed that paddle
The vortex and backflow phenomenon of point；Streamline passes through duct lip, sucks duct, and the air being inhaled into passes through paddle disk, increases paddle
Disc area improves pneumatic efficiency；Meanwhile duct outside pressure is greater than inside pressure, can generate certain power, and the force vector
It is tilted to fan center, horizontal component is cancelled out each other due to symmetrical, and vertical component is additional duct lift；
2) aircraft of dwelling of the utility model install hydrofoil unit additional more, reduce the hydrodynamic resistance when water surface takes off；Hydrofoil produces
The principle of raw lift is consistent with wing, but the density of water is about 800 times of air, therefore lesser hydrofoil Area of Wetted Surface can produce
Raw larger hydrodynamic lift；Aircraft dwell in hydroplaning more, can rely on the lift of hydrofoil generation by machine as foilcraft
Body is lifted away from the water surface without contacting with the water surface, so that reducing the Area of Wetted Surface of complete machine reduces resistance, reduces the need of engine
With power, therefore the lighter engine of weight can be selected, improves the performance of complete machine；
3) the utility model makes surface motions ability of the aircraft with fast and flexible, tilting duct spiral using hydrofoil
The use of paddle enables aircraft to move vertically and flexibly varying motion mode, the utility model aircraft can have both flight of verting
The characteristic of device, foilcraft；
4) at military aspect, aircraft can be loaded in amphibious assault ship；When execution task, can in high-altitude high-performance cruise,
Distant reconnaissance is carried out, the water surface can be quickly fallen to after finding enemy, by its excellent Stealth Fighter and quick performance of moving under water
Close to target, the weapon carried after certain distance using it is reached to enemy's progress attack action；Aircraft have hydrofoil and
The rapid mobility for quadrotor of verting, can target of attack on the hop, and battlefield can be fled from rapidly；
5) at civilian aspect, aircraft can be executed for a long time using its hover characteristic and excellent water surface activities ability
Environmental monitoring task, without returning to ground.Aircraft can execute search and rescue task on the water surface, search and rescue phase with conventional helicopters
Than can directly be parked on the water surface and implement to rescue by lifting rope without rescue personnel, and then improve rescue speed and drop
Low rescue risk.Aircraft also can be widely used to travel industry, such as the water surface is gone sightseeing, flight experience.
