A Spacecraft Explosive Separation-Guided Safe Recovery Test Device

Abstract

The invention belongs to the spacecraft structure dynamic test technical field and relates to a spacecraft explosion separation guiding type safety recovery test device. The spacecraft explosion separation guiding type safety recovery test device is characterized in that the spacecraft explosion separation guiding type safety recovery test device comprises an aircraft main bundling device connecting section and main bundling devices; the upper part of the aircraft main bundling device connecting section is connected with a boundary simulation device through a cabin section change-over connection tool; one end of each main bundling device is in bundling connection with a spacecraft, and the other end of the corresponding main bundling device is connected with the upper part of a guiding type recovery device; the lower part of the guiding type recovery device is fixed onto the ground through hinges; a sensor is installed in the aircraft main bundling device connecting section; the sensor is connected with a test system; buffering recovery pads are laid on the ground; and after a test is started, the main bundling devices are unlocked and separated, and the separated main bundling devices and the guiding type recovery device rotate along the hinges.

Description

technical field [0001] The invention belongs to the technical field of spacecraft structural dynamics test, and in particular relates to a spacecraft explosion-separation-guided safe recovery test device. Background technique [0002] Various separation actions during rocket flight, such as interstage separation, star-rocket separation, fairing separation, and unlocking of the main binding device, must be unlocked through the explosion of pyrotechnics. The size of the explosive force and the accuracy of the explosion time directly affect the separation effect and attitude control, and the strong high-frequency impact environment generated by the explosive device itself affects the performance of the equipment on the arrow. From the perspective of overall design, it is necessary to simulate the state of explosive separation in flight on the ground, and comprehensively study the environmental problems, design problems, and separation attitudes of various stages in the state of...

Problems solved by technology

[0007] The technical problem solved by the present invention is: in order to overcome the deficiencies in the prior art, the present invention provides a kind of spacecraft explosion separation guide safety recovery test device, which adopts the "rotation guide + sliding pair" safety guide recovery test device, so that the separated The ball stud can slide freely along the adjustable screw while rotating and brake and recover safely through the buffer recovery pad. The braking and recovery process automatically adapts to the separation movement track of the ball stud, which solves the gap between the ball stud and the ball stud seat. Intermittent penetration produces stagnation, which leads to the problem of not being able to unlock and separate normally
