Standartenführer in wartime Germany, and was responsible for the most powerful turboprop engine ever built, the Kuznetsov NK-12, while interned in the Soviet Union under Operation Osoaviakhim following World War II.
context_section_description: After work on the 012 was halted, design and construction of the 6,000 horsepower Jumo 022 began, with Brandner overseeing construction of the project. This project's Soviet name was the TW-2 and NK-4. The engine passed a state-examination in October 1950. This engine paved the way for the TV-022 and 2TV-2F.
