The invention relates to a method for miniaturization design of a simulation filling storage tank and dynamic control of parallel filling and discharging of the simulation filling storage tank, belonging to the technical field of low-temperature propellant conveying. The method is applied to a parallel filling and discharging system of the simulation storage tank. The parallel filling and discharging system of the simulation storage tank sequentially comprises a filling tank, a filling pump, a filling pipeline, the simulation storage tank, an exhaust valve of the simulation storage tank, a discharging and returning pipeline and a discharging and returning tank. The method comprises the following steps: allowing the pressure P<filling> of the filling tank to be equal to the pressure P<discharging> of the discharging and returning tank so as to construct an initialized static balance state; starting step input of the filling pump, controlling the pressure P<filling> of the filling tank, the pressure P<discharging> of the discharging and returning tank and the pressure P<mold> of a simulation storage tank, and constructing dynamic balance; when flow reaches a peak value Qmax, stabilizing the flow for a period of time, and completing related test work; and gradually stopping flowing, and organizing withdrawing. According to the invention, the problem that the test coverage of an existing low-temperature filling system is not comprehensive is solved, the space and weight limitation of a large low-temperature simulation storage tank on a launching tower is solved, and stable control over the dynamic parallel filling and discharging process is achieved.
Description
technical field [0001] The invention belongs to the technical field of low-temperature propellant delivery, and in particular relates to a miniaturized design of a simulated filling storage tank and a dynamic control method for parallel filling and discharging thereof. Background technique [0002] A coastal launch site has a large-scale complex low-temperature propellant filling pipe network system with the largest scale and the highest technical level in China. The system needs to conduct a liquid nitrogen low-temperature test before the official mission. Due to the lack of rocket tanks or equivalent simulated tanks, The low-temperature filling system can only conduct small-flow tests through the discharge method, and cannot simulate real filling conditions under large-flow conditions, and the test coverage is insufficient. [0003] By adding a rocket simulation storage tank on the launch tower, a closed system can be formed with the existing low-temperature filling system...
