Description

Technical Field

[0001] This invention belongs to the field of artillery projectile launching technology, specifically relating to a design method for pre-launch locking to resist launch impact and prevent seeker image unlocking. Background Technology

[0002] To improve the battlefield survivability of weapon systems, image-guided projectiles are used, enabling "fire-and-forget" operations under conditions of clear line of sight. After firing a shell, the gunner can immediately withdraw or fire the next shell. This requires: 1) Before firing, the image-guided projectile must lock onto and track the target; 2) After pressing "fire," the projectile must reliably track the target and ultimately destroy it under the conditions of launch impact and flight vibration.

[0003] Clearly, it is difficult to achieve the requirements of locking onto and tracking the target before launch, resisting the impact of launch after launch, reliably locking onto the target, and meeting the requirements of simple processing technology, convenient operation, and low cost using existing methods. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a design method for pre-launch locking, anti-launch impact, and anti-loosening guidance head image. The projectile employs a television / infrared image homing guidance method. After the gunner searches for and identifies the target, they switch the field of view to the guided head of the canister-loaded projectile, which has locking and tracking capabilities. The optical axis of the guidance head is adjusted to press against the target and lock. Before launch, the target is locked, and the receipt of a firing signal by the canister-loaded projectile guidance head is used as the launch condition; that is, if the canister-loaded projectile guidance head does not receive a firing signal, firing is prohibited. After pressing the firing button, the canister-loaded projectile guidance head receives the firing signal, and the optical axis is in an electrically locked state. After the projectile has completely exited the canister, the electrically locked state is released. After the launch disturbance disappears, the canister-loaded projectile guidance head returns to automatic tracking state until it hits the target. Compared with existing technical solutions, this invention provides more reliable guidance head resistance to launch impact and anti-loosening performance. The workflow, structure, and manufacturing process are simple, and the reliability is high, making it highly applicable.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows:

[0006] Step 1: The shell uses a TV / infrared image homing guidance method. After the gunner searches for and identifies the target, he switches the field of view to the tube-loaded shell seeker with locking and tracking capabilities, adjusts the optical axis of the seeker, presses down on the target and locks on.

[0007] Step 2: Lock onto the target before firing. The firing condition is that the seeker of the canister projectile receives a firing signal. That is, firing is prohibited if the seeker of the canister projectile does not receive a firing signal.

[0008] Step 3: After pressing the fire button, the shell seeker receives the fire signal and the optical axis is in the electric lock state;

[0009] Step 4: After the shell has completely exited the tube, the electric lock is released; after the firing disturbance disappears, the shell's seeker returns to automatic tracking mode until it hits the target.

[0010] The beneficial effects of this invention are as follows:

[0011] Compared with existing technical solutions, the seeker of this invention has more reliable performance in resisting launch impact and preventing unlocking. The working process, structure and manufacturing process are simple, the reliability is high, and it has great potential for widespread application. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] The technical problem this invention aims to solve is a design method for missile pre-launch locking, resistance to launch impact, and prevention of seeker image lock-off. The projectile employs a television / infrared image homing guidance system. After the gunner searches for and identifies the target, they switch their field of view to the canister-mounted projectile seeker, which has locking and tracking capabilities. They adjust the seeker's optical axis to lock onto the target and fire the projectile, which is then launched from the canister by the thrust of the launch engine. Normally, to ensure gunner safety, the propellant in the engine must burn completely inside the launch canister, and the launch engine stops operating before the projectile exits the canister. The entire launch process is relatively short, and the projectile will experience a significant launch impact. To prevent seeker lock-off caused by launch impact, this invention uses the receipt of a firing signal as the launch condition. Upon receiving the firing signal, the seeker increases the damping of the frame-type stabilization platform, and the optical axis is essentially in an electrically locked state. After the projectile completely exits the canister, the "electric lock" state is released. This method effectively reduces image shaking caused by launch impact, prevents seeker image lock-off, and achieves a "fire-and-forget" operational effect. The workflow is described below. Figure 1 See the schematic diagram of the shell launching device. Figure 2 See guide head locking and unlocking. Figure 3 .

[0017] The advantages of the technical solution are: 1) To prevent the seeker from disengaging due to the impact of the launch, the seeker receiving a firing signal is taken as the launch condition, that is, if the seeker does not receive a firing signal, firing is prohibited; 2) After pressing "fire", the shell can still reliably track the target under the conditions of launch impact and flight vibration, and eventually destroy the target.

[0018] Example:

[0019] The target is locked before launch, and the launch condition is that the seeker receives a firing signal. That is, if the seeker does not receive a firing signal, firing is prohibited.

[0020] Pressing the "fire" button triggers the seeker head to receive a firing signal. This increases the damping of the frame-type stabilization platform, and the optical axis is essentially in an electrically locked state. Once the shell has fully exited the tube, the "electric lock" state is released. This method effectively reduces image shaking caused by the firing impact, preventing the seeker head image from losing lock. After the firing disturbance disappears, the seeker head returns to automatic tracking mode until it hits the target, achieving a "hit and forget" combat effect.

[0021] Compared with existing technical solutions, the seeker of this invention has more reliable performance in resisting launch impact and preventing unlocking. The working process, structure and manufacturing process are simple, the reliability is high, and it has great potential for widespread application.
