Description

technical field

[0001] The invention belongs to the technical field of load-bearing of a recovery cabin, and in particular relates to a main load-bearing structure suitable for a ballistic reentry recovery cabin. Background technique

[0002] The ballistic type of the main load-bearing structure of the ballistic reentry recovery module refers to the reentry and return mode without attitude control after entering the atmosphere.

[0003] The re-entry recovery module must bear and transmit the launch load and escape load of the launch vehicle during launch, and it must bear loads such as overload, external pressure, and parachute opening impact when re-entering the atmosphere. Ballistic re-entry has its own characteristics. There is no attitude control measure during the re-entry process, which requires higher operational stability during the re-entry process. After entering the atmosphere, it is necessary to open the parachute to decelerate the cabin, and the moment the parac...
