Abstract:

This report summarizes the findings of an investigation into various possible methods of pumping hydrogen H2. The objective was primarily to find methods which might prove useful for pumping rocket plumes. A secondary objective was to select H2 pumping methods for other types of tests. The methods reported include mechanical pumping, diffusion pumping, gettering, cryosorption, chemisorption, and cryopumping. Cryosorption pumping is judged to show the most promise as a pumping method for rocket plume testing, although most of the other methods will be found useful where the pumping speed requirements are less demanding.
