The Echo I Inflation System

Front Cover
National Aeronautics and Space Administration, 1964 - Artificial satellites - 53 pages
A study has been made to determine the feasibility and selection of a subliming organic compound for inflating the Echo I satellite in a circular orbit at an altitude of 1668 kilometers. Detailed investigations have been made with regard to temperature variations of the satellite while in the sunlight and shadow, the deforming loads present in the environment of space, the rate of hole growth due to micrometeoroid bombardment, a method of selecting the proper subliming compounds, as well as the pressure time history and mass flow rate of the subliming compound vapors out of the satellite. The agreement is good between the predicted performance of the inflation system and that inferred by published experimental data.
