Spacecraft venting analysis
Webthe consumables analysis is worst-case. Some consumables are sized for a worst-case scenario other than total mission duration; for example, nitrox quantity is driven by the vent and repress scenario (see page 4). CCT-REQ-1130 specifies that systems used to control a catastrophic hazard shall be redundant, which includes the ECLSS. Web6. jan 2024 · Concept of Thermodynamic Vent System. In a TVS, when the tank pressure is controlled by gas venting, the amount of propellant loss can be reduced by protecting against heat intrusion from the outside. At the same time, heat from inside the tank can be released by another method, as shown in Fig. 1.
