Movie

He came from Kamieniec Podolski. He graduated from the Cadet Corps, and then studied at the Department of Aviation at the Faculty of Mechanical Engineering at Warsaw University of Technology (graduated in 1933). He collaborated on the design of the PZL.37B Łoś aircraft. From 1935, he was technical director of the Technical Institute of Gliding and Motorised Gliding in L'viv. He also continued his scientific work, and from 1936 he taught the mechanics of flight and aviation technology at the Technical University of L'viv.

He was evacuated to France in September 1939, where he worked in the aviation industry at the Bronzavia factories in Paris. After the fall of France, he was evacuated to the UK, and from 1941 he worked as head of aerodynamics and endurance at the Canadian factory of the British company De Havilland (DHC).

After the war, he settled in the US, where he became involved with the helicopter industry, first with Jet Helicopter Corp., and from 1947 at the Piasecki Helicopter Corp. (later Boeing Vertol), where he held managerial positions in aerodynamic research and advanced technologies.

He worked on aerodynamics for dual-rotor tandem helicopters. He led work on the vertical takeoff and landing Vertol 76 (VZ-2) aircraft with tilt rotors. He lectured in rotorcraft aerodynamics courses for engineers.

In 1969-75, Stępniewski lectured at Princeton University. He published nearly 100 papers, including the fundamental textbook for rotorcraft aerodynamics. He also translated scientific studies from Russian into English.

From 1975, Stępniewski was retired, but continued as a consultant with Boeing Helicopters in Philadelphia. In 1992, he founded his own company to conduct studies and translations for the military and NASA.

Stępniewski's main achievements include the formation of aerodynamics, flight mechanics, and the performance for more than 5,000 aircraft, the development of transparent methods for the calculation of helicopter aerodynamics, and the training of hundreds of helicopter professionals.
