While still an undergraduate he began his collaboration with TsAGI (Central Aerohydrodynamics Institute in Zhukovsky) where he conducted research on experimental and theoretical thermodynamics of air-to-air and surface-to-air missiles until 1958.

In 1958, following an invitation by academician Georgy Petrov, Ryzhov joins the Keldysh Research Centre (at the time known as NII-1); here his work focused on high speed aerodynamics.

In 1961-1992 and since 1999 he has worked at the Moscow Aviation Institute: docent, professor, pro-rector, rector (1986-1992), head of the aerodynamics department since 2003.
