How was temperature and humidity maintained inside the Apollo …
Feb 28, 2018 · Temperature and humidity within the Apollo Command Module was controlled with a system of heat exchangers, electrical heaters and water-glycol (62.5 % ethylene glycol and 37.5 % water) coolant loops. The coolant loop was used to cool the electronics mounted on cold plates and also the atmosphere of the capsule.
spacex - How do the sizes of the various proposed manned …
Feb 4, 2015 · Graphic of Apollo - Orion - CST-100 - Dragon. A great picture from User3, who found it on reddit, showing the various vehicles all side by side to scale. Another good one, doing a better job of showing manned vs reentry vs service modules parts. Great summary of the various vehicles with sizes and internal volumes:
How do we control a Reentering Capsule in the denser part of the ...
Apr 28, 2020 · For Gemini, Apollo, and Soyuz capsules, lift is achieved by offsetting the center of gravity of the reentry module from the center line of the craft. This is represented in your diagram by the "location of heavy equipment" callout, and results in the tilt of the capsule relative to the flight trajectory shown.
Why did the Apollo capsule have seats if the astronauts never …
Oct 7, 2020 · The Apollo capsule had three lying seats on its bottom, but the astronauts actually never sat in the capsule: during launch, reentry and in the ocean the astronauts were lying down, while in space they were weightless.
Why did they use uprighting bags in different sizes for the Apollo …
Jul 29, 2020 · Source: APOLLO EXPERIENCE REPORT COMMAND MODULE UPRIGHTING SYSTEM. Crew relocations within the capsule were studied to be used in case of a single bag failure. The recovery diver team was trained to upright the capsule in case of a dual or triple bag failure. The emergency CM uprighting was trained in the ocean using boilerplates.
What was Apollo 11's reentry speed at parachute deployment?
Nov 4, 2013 · The normal entry region for drogue chute deployment by barometric switch (such as was the case with Apollo 11) is described at altitudes between 25,000 and 20,000 feet (7.6 - 6.1 km) and CM velocity between mach 0.225 and 0.475 that come out at roughly 70.65 - 147.25 m/s (158 - 329 mi/h or 254 - 530 km/h). That averages out at 22,500 feet and ...
reentry - At what angle did Apollo 13 need to reenter? - Space ...
In order to reenter Earth's atmosphere safely, Apollo 13 had to approach at an inclination no shallower than 5.3 degrees, and no steeper than 7.7 degrees. Come in at 5.2 degrees or below, and the blunt-ended command module would skip off the top of the atmosphere and boing straight back into space, entering a permanent orbit around the sun.
Reason for different "cone angles" of different space capsules?
Sep 12, 2015 · Early in the Apollo Program, the capsule designers were targeting L/D ratios as high as 0.5, which requires a significant angle of attack. Thus the sidewall angle of the Apollo capsule was set at roughly 32.5 degrees to minimize direct flow impingement and the associated heating effects on the sidewall, which would impact the thermal protection ...
Did the Apollo Command module really "skip" within, or off of the ...
Jan 12, 2021 · - yes, as shown in this plot from NASA Technical Note D-6725 APOLLO EXPERIENCE REPORT – MISSION PLANNING FOR APOLLO ENTRY) Points where the trajectory inflects upward are marked by me. Apollo entry guidance could fly either controlled skip or direct entry trajectories, depending on the range to the landing site.
How did the Lunar Module dock with the rest of Apollo 11 and …
Sep 10, 2017 · The Apollo spacecraft consists of three major parts: The Command Module (CM) , a conical module where the three crew members live during launch from Earth and travel to and from the moon, and which re-enters Earth's atmosphere alone at the end of the trip;
