Abstract

The invention relates to a manned lunar surface lander sealed cabin. The sealed cabin comprises a shell (1), a plurality of reinforcing beams (2) uniformly distributed on the inner wall of the shell (1), and a plurality of composite port frames (3) arranged on the shell (1), wherein the shell (1) is formed by sequentially connecting an ellipsoidal cabin shell (101), a cylindrical cabin shell (102)and a frusto-conical cabin shell (103). According to the structure arrangement of the manned lunar surface lander sealed cabin, the sealed cabin has the performance of low average density (1.9 gram per centimeter), high bearing capacity and reliable sealing, and can meet the structure lightweight requirement of the manned lunar surface lander. The cabin structure with a carbon fiber laminated structure as the main body can achieve an extremely high load to weight ratio according to the characteristics that the average density is low and the anisotropic mechanical properties can be optimized and designed.

Description

technical field [0001] The invention relates to the design field of manned spacecraft, in particular to a sealed cabin of a manned lunar surface lander. Background technique [0002] The manned lunar surface lander is the farthest end of the lunar landing speed increment chain, and there is a strong demand for lightweight systems. In terms of structural design, compared with the unmanned lunar lander, the carrying capacity is approximately doubled, and it is required to have a sealing function and higher safety and reliability. It has been demonstrated that the weight ratio of the traditional structural design scheme cannot meet the requirements. [0003] The airtight cabin is an important section of the manned lunar surface lander. It is the cockpit for astronauts to land on the moon, return and work and live on the moon. Its structure takes into account the functions of load bearing and sealing. The airtight cabin of traditional manned spacecraft is made of aluminum allo...
