A reentry capsule is the portion of a space capsule which returns to Earth following a spaceflight. The shape is determined partly by aerodynamics; a capsule is aerodynamically stable falling blunt end first, which allows only the blunt end to require a heat shield for atmospheric entry.

The proposed CEV reentry capsule is to reenter the Earth’s atmosphere at an angle of tilt in order to achieve a hypersonic lift-to-drag ratio, L/D = 0.5, during reentry (compared to L/D = 0.3 for the Apollo capsule).

2010年2月9日 · When they fired the explosive bolts to separate the Soyuz 11 reentry capsule from another stage of the spacecraft, a critical valve was jerked open. One hundred miles above the earth, the...

In this chapter we explore the mission requirements of vehicles entering an atmosphere—whether returning to Earth or trying to land on another planet. We consider what engineers must trade in designing missions that must plunge into dense atmospheres (Figure 4.1.7-1). When we’re through, you may never skip rocks the same way again!

2021年9月17日 · The reentry capsule of the Shenzhou XII mission, with mission commander Major General Nie Haisheng, Major General Liu Boming and Senior Colonel Tang Hongbo inside, touched down at 1:34 pm at the Dongfeng Landing Site in the Badain Jaran Desert. 2021年9月17日13点34分，神舟十二号载人飞船返回舱载着航天员聂海胜、刘伯明、汤洪波在巴丹吉林沙漠东风着陆场着陆。 三位航天员身体状态良好，空间站阶段首次载人飞行任务取得圆满成功。

The reentry capsule of the Soyuz spacecraft is known by its Russian acronym "SA" for spuskaemy apparat or descent apparatus, which is officially identified as Descent Module. It is the only section of the vehicle, which returns to Earth at the end of the mission.

2021年6月24日 · One of the most harrowing parts of a spacecraft’s journey is atmospheric entry. When it collides with the air at thousands of kilometres per hour, the gasses heat up to extreme temperatures. Anything without a heat shield quickly disintegrates. Why does this heating occur? The answer is NOTfriction! The truth is much more complicated.

2021年10月3日 · In this study, the hypersonic aerodynamic characteristics of re-entry capsules designed with hyperbolic contours were investigated using the CFD code, FaSTAR, developed by Japan Aerospace Exploration Agency (JAXA).

2021年8月28日 · The reentry capsule is small in size, light in weight, and requires high accuracy in the configuration of the center of mass. The configuration design of the reentry capsule requires the lateral layout of the recovery system, which requires …

2023年10月13日 · Re-entry capsules, designed with blunt-body shapes to endure hypersonic air velocities and heat, encounter instability in the low subsonic regime during the final descent phase. Ensuring a controlled descent with the appropriate attitude for deploying deceleration systems becomes paramount.
