Abstract

The invention discloses a submarine-launched unmanned aerial vehicle which comprises a vehicle body, wings and vehicle fins, wherein the vehicle body is a flying wing layout vehicle body, and the longitudinal section of the vehicle body is of an airfoil shape. A layout mode that partial wings are built in the vehicle body is adopted for the wings, the wings are held inside the vehicle body in an underwater stage, and the wings are unfolded when the unmanned aerial vehicle flies in air. A dual-vehicle fin structure is adopted for the unmanned aerial vehicle. According to the aerodynamic layout, the resistance borne by the submarine-launched unmanned aerial vehicle underwater can be effectively reduced; the pneumatic characteristic of the submarine-launched unmanned aerial vehicle in air can be considered. According to the submarine-launched unmanned aerial vehicle, the characteristics of a flying wing layout airplane and an underwater weapon are integrated, and the problems of storage and emission of the submarine-launched unmanned aerial vehicle are solved through folding and unfolding of the wings. The submarine-launched unmanned aerial vehicle is capable of effectively combining the property of the unmanned aerial vehicle in water and air.

Description

A kind of diving penetrated unmanned plane

Technical field

The invention belongs to unmanned plane design field, particularly a kind of diving penetrated unmanned plane.

Background technology

Diving and penetrating unmanned plane is to be carried by submarine, the unmanned plane that the modes such as the main torpedo tube by naval vessels, modular mast, ballistic missile canister launcher are launched.Submarine Combat personnel control unmanned plane and airborne equipment thereof, for information scouting, targeted surveillance, target, hit, injure the combat duties such as assessment, after task completes, by submarine or ground party B personnel, are reclaimed or self-destruction.Be mainly used in: battle reconnaissance, battlefield early warning, combat success assessment, communication transfer.

The appearance of diving and penetrating unmanned plane, the unfavorable situation while making submarine and the antagonism of antisubmarine strength is greatly taken on a new look.Unmanned plane volume little, stealthy good, voyage is far away, can allow submarine launch unmanned plane outward in the firing area of antisubmarine weapon platform, unmanned plane, from can be motor-driven to specifying waters delay emission after ship, have guaranteed the disguise of submarine.Unmanned plane has certain flying height, its airborne reconnaissance equipment can cover more wide region, obtaining reconnaissance, by data link, passes in time submarine, expands the search coverage of submarine, extend pre-warning time, improve the perception of submarine to battlefield.The reconnaissance that submarine provides according to unmanned plane can be formulated in time battle plan, determine target attack parameter, accomplish to gain the initiative by striking first.The latent unmanned plane of penetrating utilizes its airborne equipment can also carry out relay guidance and injure evaluation tasks, and unmanned plane carries after offensive weapon, can also implement to attack to target, and becoming passive protection is active attack.But dive at present and penetrate unmanned plane and have the problem that suffered resistance and the skyborne aeroperformance of unmanned plane cannot be taken into account under water.

Summary of the invention

The object of the present invention is to provide a kind of diving to penetrate unmanned plane, its aerodynamic arrangement makes aircraft can effectively reduce suffered resistance under water, can take into account the skyborne aerodynamic characteristic of unmanned plane simultaneously.And solve storage, the transmitting problem of diving and penetrating unmanned plane by the folding and expanding of wing.Thereby realize this dive penetrate unmanned plane good under water and aerial performance.

A kind of diving disclosed in this invention penetrated unmanned plane, comprises fuselage, wing and vertical fin, it is characterized in that: described fuselage is Flying-wing, and fuselage elevation profile is Airfoil, and wing adopts part to be built in the arrangement of fuselage, and afterbody is installed vertical fin; When this, dive and penetrate unmanned plane under water time, a wing part closes at fuselage interior, is longitudinal sweepback folded state; When this, dive and penetrate unmanned plane when aerial, wing launches.

As the further improvement of technique scheme, described Airfoil aspect ratio 3.5-4.5, root sends than 2.0-3.5, and relative thickness of airfoil is 10% ~ 14%.

Another kind as technique scheme improves, and described vertical fin adopts twin vertical fin structure.

As the further improvement of technique scheme, described twin vertical fin aerofoil profile aspect ratio 3-4.5, root sends than 2.5-3.5, and relative thickness of airfoil is 10% ~ 12%, is the symmetrical airfoil vertical fin of angle in 90 °.

Another kind as technique scheme improves, and described wing is trapezoidal straight midsetwing.

Another kind as technique scheme improves, and described trailing edge is provided with flaperon.

A kind of diving of the present invention penetrated unmanned plane, and body fuselage elevation profile, by being adopted Airfoil, can guarantee the latent skyborne aeroperformance of unmanned plane of penetrating in suffered resistance under water at the latent unmanned plane of penetrating of minimizing; Can also effectively reduce the shared spatial volume of unmanned plane, be applicable to box transmitting or launch by the torpedo pipe of submarine.

The specific embodiment

Below in conjunction with accompanying drawing, embodiments of the present invention are elaborated.

As shown in Figure 1 (a) and Fig 1 (b) shows, a kind of dive of the present invention penetrated unmanned plane and comprises fuselage 1, wing 2, flaperon 3 and vertical fin 4.Fuselage 1 is Flying-wing's fuselage, can effectively reduce resistance under water.Wing 2 is trapezoidal straight midsetwing, and part is built in fuselage 1, for producing the major part of lift.Wing 2 trailing edges are provided with flaperon 3, for controlling the direction of aircraft.Afterbody is installed vertical fin 4 for guaranteeing unmanned plane course characteristic, and described vertical fin 4 adopts twin vertical fin structure.

Above-mentioned wing adopts high aspect ratio wing, aspect ratio 6 ~ 8, and taper ratio 2.5 ~ 3, aerofoil profile is selected the high lift high lift-drag ratio profile that relative thickness is 10% ~ 14%.Above-mentioned twin vertical fin is the symmetrical airfoil vertical fin of angle in 90 °, vertical fin aspect ratio 1 ~ 2, and taper ratio 2.0 ~ 3.5, relative thickness of airfoil is 10% ~ 12%.

As shown in Fig. 2 (a), Fig. 2 (b) and Fig. 2 (c); latent, penetrate unmanned plane from Launched From Underwater; when it is under water time; dive and penetrate unmanned plane wing 2 for longitudinal sweepback folded state; flaperon 3 parts are shunk in fuselage interior; the resistance of wing 2 is also protected to flaperon 3 structures simultaneously reducing water, simultaneously the wing section in water can effectively guarantee again fuselage steadily.

As shown in Fig. 3 (a), Fig. 3 (b) and Fig. 3 (c), in preset height, (be assumed to be 10m transmitting under water, being preset as unmanned plane height increases after 10m) wing 2 becomes straightened condition from longitudinal sweepback folded state, dives to penetrate unmanned plane and from submersible pneumatic layout, become aerial aerodynamic arrangement.But consideration actual conditions, such as reasons such as wave, fixed high inaccurate, instrument errors, these wing 2 expansion processes likely under water, aerial or by completing in aerial process under water.Affected by the side force of the generations such as wave, wind-force less, can reduce the possibility that unmanned plane side direction is toppled

The concrete application approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
