His chief engineer during this period was another Swiss Louis Massuger. Traditionally aircraft engines were manufactured by machining separate steel cylinders and then bolting these assemblies directly to the crankcase. Birkigt's novel solution called for the engine block to be formed from a single piece of cast aluminum and into which thin steel liners were secured. Manufacturing an engine in this way simplified construction and resulted in a lighter yet stronger more durable engine. Hispano-Suiza's aero engines produced at its own factories and under license became the most commonly used aero engines in the French and British air forces powering over half the alliance's fighter aircraft. Increased demand during World War I required licensing of this engine manufacturing in France England and the U.S. The Wright-Martin Aircraft Corporation later the Wright Aeronautical Corporation acquired the American rights and claimed improvements during further development.
