Description

Oblique emission supporting and orienting device and emission method using same

Technical Field

The invention relates to a rocket and missile launching device, which is mainly used for realizing the supporting and orienting of the rocket and missile launching device and inhibiting sinking and low head disturbance caused by oblique launching.

Background

Tilt launching is an important mode of rocket and missile launching all the time because of high aiming precision and no need of complex turning control algorithm and power device. During oblique launching, the directional supporting mode has an important influence on initial disturbance of rocket and missile launching, and further influences subsequent flight trajectory or control efficiency.

At present, the rocket and missile inclined launching directional support mainly adopts two forms of non-synchronous derailment and synchronous derailment. When the projectile is launched off-orbit at non-same time, after the mass center of the projectile leaves the directional support structure, the moment generated by the gravity of the projectile at the rear support position can cause the rocket and the missile to generate obvious low head angle and low head angle speed, and the initial disturbance of the launching is larger. And when the projectile body is launched off the track, the supporting structure slides away simultaneously when the projectile body moves in the launching device, so that low-head disturbance can be effectively reduced, but the projectile body is still positioned in the launching device after the rear part is supported off the track, the whole sinking of the projectile body under the action of gravity requires the launching device to have a larger yielding distance, and a larger structural dimension is required in the height direction. The low head disturbance of the non-simultaneous derailment and the sinking distance of the simultaneous derailment become important factors for restricting the design of the rocket and missile inclined launching device.

On the launch support, the usual types include various forms of guide feet, adapters, belts, etc. The traditional supporting structure adopts a single supporting form, the supporting load born by the projectile body in the launching process is mainly used for balancing gravity and restraining motion disturbance beyond the launching direction, comprehensive application of the supporting structure and the supporting load is less considered, and no matter which single supporting structure is adopted, the low-head disturbance and the sinking suppression of the launching are difficult to realize simultaneously.

For the above reasons, the present inventors have made intensive studies on a tilt-emitting mechanism, and have expected to design a tilt-emitting support orientation apparatus and an emitting method using the same, which can solve the above problems.

after the rear adapter leaves the track, the projectile body is mainly subjected to downward gravity acting force and downward acting force of the guide rail on the rear supporting legs 8, at the moment, the projectile body cannot be obviously lowered, and the arrangement position of the rear supporting legs 8 is close to the tail of the projectile body, so that the lowering of the projectile body and sinking of the projectile body can be effectively restrained until the projectile body leaves the track completely.

The rear adapter is arranged at a position relatively close to the tail part of the projectile body, the time from the rear adapter to the complete derailment of the projectile body is smaller than the time from the mass center to the derailment of the rear adapter, so that the time length of the launching stage of the phenomenon of low head and sinking in the projectile body launching process can be greatly shortened through the rear adapter and the rear support leg, and the final low head and sinking amount of the projectile body are smaller.

The invention has been described above in connection with preferred embodiments, which are, however, exemplary only and for illustrative purposes. On this basis, the invention can be subjected to various substitutions and improvements, and all fall within the protection scope of the invention.
