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...

Embodiment Construction

[0039] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0040] The invention provides a main load-bearing structure suitable for a ballistic reentry recovery cabin, see attached Figure 1-6 , including: head shell 1, stabilizing skirt 2, skirt bottom 3, instrument panel 4, transition bracket 5, support seat 6, platform 7, umbrella cabin device 8, pull rod 9 and adjusting gasket 10;

[0041] The head shell 1 is a shell composed of a truncated cone and a spherical segment, wherein the bottom surface of the spherical segment is docked with the small end of the truncated cone;

[0042] The stable skirt 2 is a frustum-shaped shell, and three annular bosses coaxial with the stable skirt 2 are processed on the inner peripheral surface of the stable skirt 2 along its axial direction, which are respectively the upper end frame and the middle spacer frame of the stable skirt 2. And the bottom end frame; The upper end fr...
