Abstract
Current activities in seals for space propulsion turbomachinery that the NASA Lewis Research Center sponsors are surveyed. The overall objective is to provide the designer and the researcher with the concepts and the data to control seal dynamics and leakage. Included in the program are low-leakage seals, such as the brush seal, the “ceramic rope” seal, low-leakage seals for liquid oxygen turbopumps, face seals for two-phase flow, and swirl brakes for stability. Two major efforts are summarized: a study of seal dynamics in rotating machinery and an effort in seals code development.
