Abstract
The utility model discloses a microminiature pulse engine, including the cabin body, igniter, powder column, fender medicine board and spray tube, the circumference equipartition has the exhaust hole on keeping off the medicine board, and the one side that just keeps off the medicine board is provided with protruding piece uniformly, the one end fixed connection igniter of the cabin body, other end fixed connection spray tube, powder column keep off the medicine board and install between powder column and spray tube in arranging the cavity at cabin body middle part in, keep off one side that the medicine board has a protruding piece just to the spray tube, and it is inconsistent with the convergent portion of spray tube to keep off the protruding piece of medicine board outer fringe, and it is spacing in the internal axial displacement that does not take place in cabin with the powder column to keep off the medicine board, and protruding piece increases the clearance between fender medicine board and the spray tube convergent portion, the utility model discloses it is inconvenient, dangerous to solve traditional pulse engine powder charge, powder column incomplete combustion, and the sweay is less, the less problem of thrust.
Description
Technical field
This utility model relates to the technical field that projectile correction controls, and is specifically related to a kind of microminiature pulsed motor.
Background technology
The domestic field being modified controlling by pulse vector technology revised in actuator in the airborne equipment part of Correction Projectiles is but without obtaining substantial progress, still in the primary research stage.
Traditional pulse vector correction actuator is because only performing discontinuous limited number of time action, without target goal continuously for a long time as guided missile, also need not cannon and Shell-feeding system being transformed, therefore the application of actuator reduces the cost of guided missile.There is significant limitation in range of application in traditional Impulse Thruster, when ensureing structural safety, its impulse value is less than normal, it is impossible to effective longitudinal direction (orientation) is moved is modified, it is necessary to carry out innovative design from structure and principle.
It is as follows to there is shortcoming in traditional Impulse Thruster:
1, powder charge is inconvenient；
2, powder column incomplete combustion, is sprayed body by air-flow；
3, sweay is less, and thrust is less.
Utility model content
In view of this, this utility model provides a kind of microminiature pulsed motor, it is possible to solving traditional pulsed motor powder charge inconvenient, dangerous, powder column incomplete combustion, sweay is less, the problem that thrust is less.
Realize the technical solution of the utility model as follows:
A kind of microminiature pulsed motor, including nacelle, igniter, powder column, grate and jet pipe；
On described grate, circumference is evenly equipped with steam vent, and the side of grate is provided with protruding block equably；
One end fixed connection point fire tool of nacelle, the other end fixes connecting spray nozzle, powder column is placed in the cavity in the middle part of nacelle, grate is arranged between powder column and jet pipe, grate has the side of protruding block just to jet pipe, grate outer rim protruding block is inconsistent with the converging portion of jet pipe, and powder column is limited in nacelle and axial displacement does not occur by grate, and protruding block increases the gap between grate and jet area contraction section.
Further, described nacelle is cylindrical empty cavity configuration.
Further, described powder column is hollow cylindrical structural.
Beneficial effect:
1, this utility model adopts the powder column of molding as main charge, has easy installation, easily produce compared with existing microminiature pulsed motor, the feature that explosive payload is big, drastically increases the safety of microminiature pulsed motor assembling process.
2, this utility model is owing to adding grate, not only effectively fixes the position of powder column, and stops unburned powder column to spray with gas, improves the combustion rate of main charge.Protruding block on grate adds the gap between grate and jet pipe, adds the free air space of high-temperature fuel gas, it is prevented that grate deforms in hot environment and causes combustion gas successfully not spray from jet pipe.
3, the amount of main charge is directly proportional to specific impulse；The main charge selected due to this utility model uses the powder column of molding to increase total dose and the burning area of medicine, effectively raises the speed of combustion gas ejection, increases the momentum of burning.

Detailed description of the invention
Develop simultaneously embodiment below in conjunction with accompanying drawing, this utility model is described in detail.
This utility model provides a kind of microminiature pulsed motor, as described in Figure 1, including nacelle 1, igniter 2, powder column, grate 4 and jet pipe 5；The structure of jet pipe 5 is as shown in Figure 4.
As it is shown on figure 3, circumference is evenly equipped with multiple steam vent on described grate 4, and the side of grate is provided with protruding block equably；
One end fixed connection point fire tool 2 of nacelle 1, the other end fixes connecting spray nozzle 5, powder column is placed in the cavity in the middle part of nacelle 1, cavity in the middle part of nacelle 1 is combustor 3, grate 4 is arranged between powder column and jet pipe 5, and grate 4 has the side of protruding block just to jet pipe 5, and grate 4 outer rim protruding block is inconsistent with the converging portion of jet pipe 5, powder column is limited in nacelle 1 and is not subjected to displacement by grate 4, and protruding block increases the gap between grate 4 and jet pipe 5 converging portion.
Described nacelle is cylindrical cavity structure.
Described powder column is hollow column structure.As shown in Fig. 2 (a) and (b).
Work process: when igniter 2 receives ignition order, lead fire tool ignition charge within 2, ignition charge burning produces heat, combustor 3 pressure in microminiature pulsed motor nacelle 1 becomes big simultaneously, when reaching main charge burning-point, ignite the main charge fixed by grate 4, produce substantial amounts of heat and gas further increases the pressure of microminiature pulsed motor inner trajectory, when reaching certain pressure intensity value, gas is sprayed from jet pipe 5 by the pore of grate 4, under the effect of opposing force, revise body lengthwise position.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
