Abstract

The invention discloses a starting basket device capable of actively adjusting the bubble breaking pressure of a metal net curtain. The device comprises a low-temperature storage tank wrapped with a heat insulation layer, a liquid discharge outlet is formed in the bottom of the low-temperature storage tank, a starting basket is placed at the bottom in the low-temperature storage tank, an exhaust pipe is arranged at the top of the starting basket, and a second metal net curtain is arranged at an outlet in the top of the exhaust pipe; solenoids are arranged around the exterior of the low-temperature storage tank, or the solenoids are arranged in the low-temperature storage tank and soaked in liquid hydrogen and liquid oxygen fluid; the solenoids are connected with a power supply through an electric wire; an electric switch is arranged on the electric wire; a magnetic field is introduced by utilizing the characteristic of weak magnetism of liquid hydrogen and liquid oxygen, and the bubblebreaking pressure of the metal net curtain in the starting basket is changed by adjusting the electrification of the solenoids, the electrification direction, the current magnitude and the like, so that the stability of the starting basket in a liquid storage stage is improved, and the liquid filling rate in a refilling stage is increased.

Description

Technical field [0001] The invention relates to the technical field of spacecraft space liquid fuel supply, in particular to a starter basket device for actively adjusting the bubble breaking pressure of a metal mesh screen. Background technique [0002] The specific impulse of the liquid hydrogen / liquid oxygen propellant combination can reach 450s. It has been widely used in the field of aerospace propulsion. The liquid hydrogen / liquid oxygen combination has outstanding performance advantages in the upper stage of rockets and space vehicles, realizing its space safety management and Efficient utilization is of great significance to space exploration. [0003] Spacecraft using a combination of liquid hydrogen / liquid oxygen may experience multiple zero-gravity taxis and secondary ignition in space during orbit. Space ignition requires the fuel system to deliver an all-liquid cryogenic propellant without entrapment to the engine. The realization of gas-liquid separation and full-liq...
