Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
The present invention is that a kind of rotation controls solid rocket divert and attitude control motor, as shown in Figure 1, comprises aircraft skin body 1, rail control power system 2 and appearance control power system 3.
As shown in Figure 2, rail control power system 2 comprises two precise tracking 4;
Precise tracking 4 as shown in Figure 3, comprises precise tracking housing 12, precise tracking heat insulation layer 13, precise tracking powder column 14, rail control combustion gas 90 degree of pipelines 15, precise tracking jet pipe 16;
Identical with Conventional solid rocket motor, bond between two between precise tracking housing 12 and precise tracking heat insulation layer 13, between precise tracking heat insulation layer 13 and precise tracking powder column 14; Rail control combustion gas 90 degree of pipelines 15 are connected with the eccentric blast tube of precise tracking housing 12 by screw thread; The ablation caused for avoiding high-temperature fuel gas, rail control combustion gas 90 degree of pipelines 15 and precise tracking jet pipe 16 adopt high temperature resistant composite (such as C/SiC, C/C etc.), adopt thread connecting mode between the two.
The large and small gear of driving gear set 9 is fixedly connected with the axle of precise tracking 4, the running shaft of rail control driver 7 respectively.
Rail control rolling bearing 10 is placed in the side of driving gear set 9 near precise tracking 4, be convenient to precise tracking 4 rotate, the axle interference fit of its inner ring and precise tracking 4, outer shroud and precise tracking support 8 are connected, and precise tracking support 8 is fixed on (link such as bolt does not illustrate in the drawings) on aircraft skin body 1 by links such as bolts.
Rail control driver 7 is positioned at rail control rolling bearing 10 side, and rail control driver 7 shell is fixedly connected with rail control servo fixing frame 6; Rail control servo fixing frame 6 is fixed on (link such as bolt does not illustrate in the drawings) on aircraft skin body 1 by links such as bolts.
Two precise tracking 4 are staggered relatively, can independently rotate, and therefore only to two motors axially retraining, need provide axially locating and support reaction at two ends by the shaft shoulder of respective rail control rolling bearing 10 and precise tracking 4.Place rail control between two motors and connect rolling bearing 11, make both rotation non-interference, the inner ring of bearing and outer shroud respectively with two engine shaft transition fit.
The effect of rail control power system 2 is that therefore the jet pipe 16 of precise tracking 4 should be in the centroidal planes of aircraft, and two motors are staggered relatively up and down, axis and aircraft dead in line for aircraft provides the power of crossrange maneuvering.Precise tracking structure is similar to Conventional solid motor, and rail control powder column 14 is cigarette burning, and the high-temperature fuel gas of generation, through the crooked pipeline 15 of 90 degree, is discharged by rail control jet pipe 16.During work, each precise tracking 4 integral-rotation, because its rotary inertia is comparatively large, rail control servo driver 7, by driving gear set 9 transmission, drives precise tracking 4 to rotate.
Appearance control power system 3 as shown in Figure 4 and Figure 5, comprises four attitude control engines 5.
The effect of appearance control power system is for aircraft provides the moment of pitching, driftage and rolling, and therefore attitude control engine 5 arranged off-centre is in the head end of aircraft or end, and running shaft is with aircraft axis being parallel but do not overlap.4 attitude control engines 5 circumferentially distribute.
Attitude control engine structure is identical with precise tracking structure, only has the difference of size, does not do repeat specification at this;
Appearance control driver 17 shell is fixedly connected with appearance control servo fixing frame 18, and appearance control servo fixing frame 18 is fixed on aircraft skin body 1 by links such as bolts.The axle of attitude control engine 5 is fixedly connected with by coupling with the running shaft of appearance control driver 17.To use in appearance control rolling bearing 21 under rolling bearing 19 and appearance control, so that attitude control engine 5 rotates.Two bearings is placed in the upper and lower end of attitude control engine 5 respectively, the axle interference fit of inner ring and attitude control engine 5, and outer shroud is connected with attitude control engine upper bracket 20, attitude control engine lower support frame 22 respectively.Attitude control engine upper bracket 20, attitude control engine lower support frame 22 are fixed on aircraft skin body 1 by links such as bolts.
During work, each attitude control engine 5 integral-rotation, its rotary inertia is less, and appearance control servo driver 17 can directly drive attitude control engine 5 to rotate.
On this basis, according to actual needs, the number of motor can be adjusted, as shown in Figure 6, comprise three precise tracking.For meet simultaneously precise tracking axis to overlap with aircraft axle and jet pipe in conplane requirement, precise tracking 23 is annular, is positioned over one heart outside precise tracking 24.Precise tracking 24 is identical with aforementioned precise tracking 4 structure with precise tracking 25, does not do more descriptions.Control for the independence realizing precise tracking 23 and precise tracking 24 rotates, the rotating shaft designs at precise tracking 23 two ends is hollow-core construction, and the running shaft of precise tracking 24 extends there through, and two engine revolution axles rotate with one heart and do not contact.Now, the housing diameter of precise tracking 23 is comparatively large, and the external diameter of corresponding aircraft casing is comparatively large, and precise tracking 25 exists larger space, therefore, four attitude control engines 26 can be arranged in precise tracking 25 around, to make compact structure.
Rail control power system of the present invention comprises multiple (two and more than) precise tracking, places up and down.The structure of each precise tracking is substantially identical, forms primarily of rail control thruster, rail control servo-system, rolling bearing and fixed connecting piece.The structural type of rail control thruster is identical with general solid engines, powder column axis and aircraft dead in line, and the high-temperature fuel gas that powder column burning produces, through the pipeline of bending 90 degree, is sprayed by jet pipe, produces horizontal thrust.A rolling bearing is respectively placed with, so that engine revolution before and after precise tracking.Bearing outer ring is fixed on aircraft skin body by support.Rail control driver is fixed on aircraft skin body by support, drives rail control thruster integral-rotation by driving gear set.
Appearance control power system of the present invention: comprise four attitude control engines, eccentric placement, circle distribution.The structure of attitude control engine is substantially identical with precise tracking.Difference is, the axle of appearance control driver is directly connected on attitude control engine, drives appearance control thruster integral-rotation.
