Embodiment Construction

[0040] like Figure 1-10 As shown, the pina satellite star-rocket fixing and separating device of this embodiment includes: a base plate 1 , two pairs of satellite supporting bases 2 oppositely arranged on the fixed base plate 1 , a satellite connection and separation assembly 3 and a satellite ejection mechanism 4 .

[0041] The satellite connection and separation assembly 3 includes a titanium rod 31 installed in a pair of satellite support bases 2 and an pyrotechnic device 32 that cuts off the corresponding tie rod 31 . Each titanium rod 31 stretches out the satellite support surface 21 of the corresponding satellite support base 2 and is connected with the satellite 5 and the satellite 5 is pressed on the satellite support surface 21. Any pair of satellite support bases 2 is an angle steel structure with opposite openings. The satellite supporting seat 2 equipped with titanium rod 31 comprises vertical angle steel 23, vertical plate 24 and top plate 25 connecting angle ste...

Abstract

The invention discloses a Pico/Nano satellite and rocket fixing and separating device. The Pico/Nano satellite and rocket fixing and separating device comprises a bottom plate. Satellite supporting bases, pull rods, pull rod cut-off mechanisms and satellite popping mechanisms are fixed to the bottom plate. At least one pair of satellite supporting bases is arranged. Any one pair of satellite supporting bases is oppositely arranged in pairs. At least one pair of pull rods is arranged. Each pair of pull rods is installed in any one pair of satellite supporting bases respectively. Each pull rod stretches out of a satellite supporting face of the corresponding satellite supporting base to be connected with a satellite and presses the satellite on the satellite supporting face. According to the Pico/Nano satellite and rocket fixing and separating device, when the satellite and the bottom plate are connected, pull force and pressure exerted on the bottom plate are exerted on the same straight line, and therefore the interaction force between the bottom plate and the satellite is reasonably distributed, the integral structure is simple and stable, meanwhile, installing is convenient, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the technology of fixing and separating aircraft, in particular to a device for fixing and separating rockets of pina satellites. Background technique [0002] With the development of micro-satellites and aerospace technology, it is urgent to develop new connection and separation devices with small size, light weight, low impact or even no impact, so as to adapt to the growing micro-satellites (pico-satellites, nano-satellites) and small launch vehicles. Application requirements. The satellite-rocket separation mechanism is a mechanism that reliably connects the satellite and the rocket, and realizes the reliable separation of the satellite-rocket after it enters orbit, and plays an important role in the satellite project. At present, most of the major launch vehicles in the world use tape locking devices as the connecting and separating mechanisms for satellites and rockets. However, as the size and weight of satellites beco...
