Abstract

The invention relates to a grid rudder unfolding and locking mechanism for an aerospace transport vehicle, which uses a plane scroll spring to drive the grid rudder to unfold, uses the locking plane at the end of the support rib to cooperate with the locking plane on the base, and realizes the forward direction through mechanical limit. Locking, using the locking rod assembly to cooperate with the locking track surface in the inner cavity of the support rib, and realizing reverse locking through the principle of self-locking. The invention can realize the unfolding and locking of grid rudders driven and folded, and has beneficial effects such as simple structure, reliable deployment, high locking rigidity and strong bearing capacity, etc. The drop area control and fixed-point recovery provide technical support.

Description

A grid rudder deployment locking mechanism for space transporter technical field The present invention relates to the technical field of space transporter mechanisms, in particular to a kind of spaceflight transporter that is suitable for controllable drop zone The grid rudder deploys the locking mechanism. Background technique At present, my country's launch vehicle does not yet have the ability to control the sub-level drop area, and the distribution range of a sub-level drop area is generally 30% wide. km, 50 to 70 km long. At present, more than 20 to 30 space launch missions are carried out every year, and tens of thousands of people need to be evacuated each time. The wreckage destroyed houses, high-voltage lines, farmland, highways and other civilian facilities, polluted water sources, and provided safety to the lives and property of the people in the affected areas. It will cause serious harm and disrupt the normal life and production order. In addition, the...
