摘要

Investigations to create a new class of economical and reliable seals for rotors of turbo-driven pump unite used in liquid rocket engines were carried out on one pulsed sealing assembly with combined electro-erosional coatings in media with different thermal and physical properties ( water, liquid oxygen and nitrogen ) and in the wide range of operating conditions (n = 8400-18400 rpm, p=0,8 - 12,2 MPa). These investigations confirmed the high serviceability of the seal mentioned above.
