The rounded shape (blunt body) of a capsule forms a shock wave that keeps most of the heat away from the heat shield, but a thermal protection system is still necessary. The space capsule must be strong enough to withstand reentry forces such as drag , and must reenter at a precise angle of attack to prevent a skip off the surface of the ...
All three designs employed a mission module cabin separate from the command module (piloting and re-entry cabin), and a propulsion and equipment module. Martin studied three different reentry module shapes, including a conical capsule vehicle similar to the STG configuration. GE also studied several reentry module shapes.
This provided a rotational moment during reentry, angling the capsule and providing some lift (a lift to drag ratio of about 0.368 [13]). The capsule was then steered by rotating the capsule using thrusters; when no steering was required, the capsule was spun slowly, and the lift effects cancelled out.
Apollo Command Module and its position on top of Saturn V. The command module was the control center for the Apollo spacecraft and living quarters for the three crewmen.
The Crew Module Atmospheric Re-entry Experiment (CARE) is an experimental test vehicle for the Indian Space Research Organisation's future ISRO orbital vehicle called Gaganyaan. [1] It was launched successfully on 18 December 2014 from the Second Launch Pad of the Satish Dhawan Space Centre , by a LVM3 designated by ISRO as the LVM 3X CARE mission.
Gemini SC-2 (Spacecraft No. 2) was the second NASA Project Gemini full-up reentry capsule built. This McDonnell Gemini capsule was the first space capsule to be reused, flying twice in suborbital flights. SC-2 flew on Gemini 2 and OPS 0855 flights.
The assembled SHEFEX II body. SHEFEX (Sharp Edge Flight Experiment), is an experiment conducted by the German Aerospace Center (DLR), for the development of some new, cheaper and safer design principles for space capsules, hypersonic vehicles and spaceplanes with re-entry capability in the atmosphere and their integration into a complete system.
Project FIRE (Flight Investigation Reentry Environment) was a United States NASA effort to determine the effects of atmospheric entry on spacecraft materials. [1] [2] Project FIRE used both ground testing in wind tunnels and flight tests to test the effects of reentry heating on spacecraft materials, using a subscale model of the Apollo Command ...
