Description

Technical Field

[0001] The present invention relates to a transplanting device, and more particularly to a transplanting device for automatically extinguishing fire after a solid rocket engine test run. Background Art

[0002] In the forward design process of a solid rocket engine, the thickness of the insulation layer is usually obtained by dissecting and measuring the engine combustion chamber after a ground ignition test. This method requires the remaining fire in the combustion chamber to be extinguished as soon as possible after the engine operation is completed. However, after the ground static test of the engine is completed, since the combustion chamber is directly connected to the external air through the nozzle, the insulation layer in the combustion chamber will continue to ablate, resulting in the fact that the dissected and measured insulation layer thickness is not the true and accurate thickness after combustion, affecting the accuracy of the design.

[0003] To prevent the ablation of the insulation layer after the engine operation is completed and to retain the true ablation state of the insulation layer after the engine operation to the greatest extent, at present, the method of manually blocking the nozzle of the engine after the test run is usually adopted, that is, a designed plug is used to block the engine nozzle, and by isolating the engine combustion chamber from the external air, the remaining fire in the combustion chamber is slowly extinguished under anoxic conditions. However, the effect of the current action mode is not obvious, and there are mainly the following two problems: First, after the engine test is completed, it is necessary to confirm safety before notifying the operator to come onto the stage, with poor timeliness and a long ablation time of the insulation layer; Second, there are still residues mixed in the combustion chamber after the engine operation and the insulation layer continues to burn, with great randomness, and the fire at the nozzle is large, resulting in a large safety risk in the process of manually blocking the nozzle.

[0004] Automatically extinguishing the fire after a solid rocket engine test run is an effective way to solve the problem of manually blocking the nozzle. To build a fast, safe, and efficient suffocating fire extinguishing ability after the engine test run, it is first necessary to introduce an automation technology suitable for the solid rocket engine test run environment, design an adjustable transplanting platform that can adapt to the special application environment of the engine test run, and break through the problems of rapid locking and reliable fixation in a large jet flow noise and strong vibration environment, so as to solve the universal application bottleneck of extinguishing fire after the test run of engines with different structures.

[0005] A suffocation and cooling device for a solid rocket motor with an application number of CN111122166 A and a publication date of May 8, 2020, includes a rotating mechanism, a feeding mechanism, a spray gun mechanism, and a pneumatic control system. The swing cylinder Q1 of the rotating mechanism drives the support arm to swing and adjust the coaxiality between the spray gun mechanism and the motor nozzle. The feeding cylinder Q2 of the feeding mechanism drives the spray gun mechanism to send the cooling medium into the motor nozzle. The device support of this suffocation and cooling device for a solid rocket motor is made of 4040 aluminum profile, which is light in weight but has significantly insufficient support stiffness. The device support is fixed to the T-shaped groove outside the test stand by means of fastening bolts, which is inconvenient to operate; due to the large inertia of the swing arm, the entire swing arm has an obvious rebound situation, and the spray gun extended during the rebound process is extremely easy to collide with the motor nozzle. Therefore, proceeding from the actual situation and combining with the test site of the test run, it is urgent to develop a stable and reliable transplanting device applicable to automatic fire extinguishing after the test run of a solid rocket motor, which can change the previous fire extinguishing method after the test run of a solid rocket motor, achieve rapid, safe, and efficient suffocation fire extinguishing after the motor test run, help optimize the design of the thickness of the motor insulation layer, and accelerate the light weight and performance improvement of the motor.
