He also constructed the first aircraft that was heavier than air. He is now recognized as the father of aviation. He came up with many principles of heavier-than-air flight.

This heat is added by injecting fuel into the combustor and igniting it on a continuous basis. The hot compressed air at point 3 is then allowed t o expand (from point 3 to 4) reducing the pressure and temperature and increasing its volume.
