Hyper engine

The hyper engine was a possible aircraft engine model that could produce 1 horsepower per cubic inch (46 Kilowatt per Litre) 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 and all of the programs were canceled. The surviving engines became museum pieces.
