Abstract
The invention discloses a guided missile or torpedo with a surface pit structure, and the guided missile or torpedo is characterized in that the surface of a guided missile or torpedo body is provided with a plurality of pits to form the surface pit structure. According to the invention, the range and speed of the guided missile or torpedo are increased by utilizing air and water flow dynamic performances of the pit structure to reduce air and water flow resistances, so as to improve the stability; and the guided missile or torpedo with the surface pit structure, provided by the invention, has the characteristics of simple structure, low cost and high performance, and can be widely applied to military and civil fields.
Description
Technical field
The present invention relates to the surface texture of a kind of guided missile, torpedo, relate in particular to guided missile, the torpedo of surface crater structure with excellent air force and flow dynamic performance.
Background technology
Present guided missile, torpedo are for reducing air and resistance to water-flow; Adopt streamlined smooth surface structure mostly; But level and smooth surface texture, still can with air and the bigger resistance of current friction generates, therefore; Seek a kind of surface texture with excellent air and current performance, the range and the speed that increase guided missile, torpedo are one of emphasis that improves guided missile, torpedo performance.
Summary of the invention
In order to overcome and to solve the resistance that existing guided missile, torpedo smooth surface structure are produced; Influence the problem of its range and speed; The present invention provides a kind of guided missile, torpedo of surface crater structure; Utilize the air of bowl configurations and the resistance that the flow dynamic performance reduces air and current, increase range and speed, improve stability.
The technical scheme that technical solution problem of the present invention is taked is that at guided missile, the numerous pits of torpedo surface processing and fabricating, formation surface crater structure utilizes the excellent power performance of bowl configurations to reduce resistance.
According to aerodynamics and water flows mechanics principle; The guided missile of high-speed cruising, the place ahead of torpedo can produce the higher-pressure region; When flowing to afterbody again, the leading edge of air or current process guided missile, torpedo separates with guided missile, torpedo; Afterbody at guided missile, torpedo produces a turbulent wake zone, and air-flow that this is regional or flow fluctuation disturbance cause the pressure at rear lower.The scope of wake flow can influence the size of resistance, and generally speaking, the wake flow scope is more little, and the pressure at guided missile, torpedo rear is just big more, and air, current are just more little to the resistance of guided missile, torpedo.Guided missile, torpedo surface crater structure can make air, current form the very thin turbulent boundary layer that one deck is close to guided missile, torpedo surface; Make level and smooth air-flow or current more walk back along guided missile, torpedo; Thereby reduce the scope of wake flow; Guided missile, torpedo are in operation and have only head to contact with air or current with afterbody under the special air of surface crater structure, the effect of flow dynamic performance, and remainder is in the level and smooth veneer of tubular air or current, and this super cavitation phenomenon can make resistance descend; Reduce the frictional force of guided missile, torpedo and air, current greatly; The suffered resistance of guided missile, torpedo through the surperficial bowl configurations of estimation approximately has only 2/3 of surface smoothing structure, owing to resistance reduces, under the condition of equal thrust; The range of guided missile, torpedo and speed are corresponding to be improved; Also be wrapped in the state operation down of air film or current film owing to guided missile, torpedo, turbulent boundary layer can also weaken the fluctuating disturbance of air-flow and current, and the stability of guided missile, torpedo operation is improved.
In addition, the lift that the pit surface structure also can the lifting of missile, the guided missile that air spots is sliding; Being in operation produces spin, makes the air pressure of guided missile below higher than the top, under the effect of this air pressure; Guided missile under the situation that thrust does not have to change, can rise more soar farther.
Further, the surface crater structure also is applicable to carrier rocket, aircraft and shell.
Further, the surface crater structure also is applicable to submarine and naval vessel.
Described guided missile, torpedo surface crater shape can be circle, hexagon and rhombus.
The pit depth and the size on described guided missile, torpedo surface can be selected, and in general, the surface crater structure of aircraft such as guided missile is slightly shallow smaller, and the pit of ROVs such as torpedo is slightly bigger deeply.
The invention has the beneficial effects as follows that bowl configurations is adopted on the surface of guided missile, torpedo, can reduce the resistance of air or current; Increase range, improve the speed of service and stability, have simple in structure; Cost is low, and the characteristics that performance is high can be widely used in the military and civilian field.

Fig. 2 is the torpedo sketch map of pit surface structure of the present invention.
Among the figure, A101 Missile Body, A102 empennage, A103 pit; B101 torpedo body, B102 empennage, B103 pit.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Embodiment 1, and is as shown in Figure 1, is circular pit (A103) structure with the Surface Machining of Missile Body (A101), and empennage (A102) can be taked smooth structure, also can take bowl configurations.The guided missile of surface crater structure, in high-speed cruising, air forms the very thin turbulent boundary layer that one deck is close to the guided missile surface; Make air-flow more walk back, thereby reduce the wake flow scope, be in operation and have only head to contact with air with afterbody along Missile Body; Remainder is in the level and smooth veneer of tubular, and this cavitation phenomenon can make resistance descend, and reduces the frictional force of guided missile and air greatly; Under the condition of equal thrust; The range of guided missile and speed are corresponding to be improved, simultaneously, and the lift that the surface crater structure also can the lifting of missile.
Embodiment 2, and is as shown in Figure 2, is circular pit (B103) with the Surface Machining of torpedo body (B101), and empennage (B103) can be taked smooth structure, also can adopt bowl configurations.The torpedo of surface crater structure, in high-speed cruising, current form the very thin turbulent boundary layer that one deck is close to the torpedo surface; Make current more walk back along the torpedo body; Thereby reduce the scope of wake flow, be in operation and have only head to contact with current with afterbody, remainder all is wrapped in the level and smooth veneer of tubular; This super cavitation phenomenon can reduce the frictional force of torpedo and water; Under the condition of equal thrust, the range of torpedo and speed homogeneous phase should obtain improving, and attack performance also is improved.
