e/Hyper engine

Information
has gloss	eng: The hyper engine was a 1930s study project of the United States Army Air Corps, an effort to develop an aircraft engine capable of delivering 1 horsepower per cubic inch (46 kW/L) of engine displacement. The USAAC funded development of an engine of about 1200 cubic inches (20 L), hoping the engine's smaller size would lead to better streamlining and improved range. The engine did not enter volume production because it had been matched by existing designs by the time it was perfected.
has gloss	eng: The hyper engine was a possible aircraft engine model that could produce 1 horsepower per cubic inch of engine displacement. The term hyper engine was used only in the United States, where the Army Air Corps gave people money to make a hyper engine that had an area of 1,300 cubic inches. This happened in the 1930s. They thought that this would better help with streamlining and to help get a better range. Unfortunately, none of these designs ever made it past the production stage.
