RESEARCH AND DEVELOPMENT OF NEW VERSION OF A LIFT-OFF SEAL OF OXIDIZER PUMP
OF RD191 ENGINE
Results of calculation and design works on experimental lift-off seal operating at high pressure drop and designed to sealing liquid oxygen in oxidizer pump presents are presented in article. Results of autonomous tests proving operability of seal at conditions close to operational ones are presented. Comparison of characteristics of experimental variants with base lift-off seal of RD191 engine, confirmed high efficiency of experimental seal is conducted.
Keywords: liquid rocket engine, turbopump unit, lift-off seal, test.
