Transient Thermal Simulation of Apollo Spacecraft and ECS

An analytical thermal model of the project Apollo Command Module has been developed by the General Electric Co., Apollo Support Dept. for the National Aeronautics and Space Administration, Manned Spacecraft Center. This model simulates the entire spacecraft structure and the four closed fluid loops of the Environmental Control System.

The configuration of the model is discussed as well as the correlation of this type model with test data. Also covered are the environmental data used in conjunction with the model for mission analysis. Typical results of the mission analyses are discussed in more detail.
