Post-war, Mironov developed methods for aerodynamic research using free-flying models, making a breakthrough in collecting in-flight data concerning wing profile pressure distribution at transonic speeds.

[2] In 1968-1975, Mironov together with V. S. Grachev conducted flight studies of the aerodynamic characteristics of an experimental ogival delta wing designed for the then developing supersonic airliner Tupolev Tu-144.

He played a major role in the USSR's communication with the International Civil Aviation Organization in the development of aircraft type certification and noise regulation, especially for supersonic transport aeroplanes.

Regarding the MiG-15 training flight accident, Mironov developed and publicly supported a scientifically-grounded position against numerous different explanations and conspiracies.

When Utkin died in 1981, Mironov became the institute's chief (1982),[16] serving until Konstantin Vasilchenko [ru] was appointed in 1985.

Lasting issues in his left elbow hindered Mironov's ability to train and apply for a test pilot position.

However, he passed the check flight with the institute's senior test pilot, proving he could fly light transport aeroplanes such as the Po-2.

[7] Mironov's flight training in gliding started before the war in Chkalov Central Aero-club in Moscow under the supervision of Sergei Anokhin.

[7][18] Mironov's flight instructor was Margarita Ratsenskaya, the aero-club's gliding squad commander and Anokhin's wife.

[7] Mironov was married to Olga Yevgenevna Rudneva (Russian: Ольга Евгеньевна Руднева; 1919–2017) for 77 years.

[5][19] Their daughter, Olga Maksakova (Mironova) (Russian: Ольга Арсеньевна Максакова (Миронова); born 1946) is a psychotherapy practitioner and a Doctor of Medicine working for the Burdenko Neurosurgery National Research Center.

[21] On his 100th birthday ceremony on 25 December 2017, Mironov was awarded a Chest Badge "Medal of Small Arms Maker M.T.
