Abstract:

An engine is described that derives its propulsive energy from the flash expansion of liquid nitrogen from a liquid form to a gaseous form. The gaseous nitrogen is forced to escape from the rear of a casing of the engine, thereby providing a propulsive force to the casing. The escaping gaseous nitrogen, mixed with air, is harnessed to rotate a first fan that in turn rotates a second fan that draws air into the front of the engine. The warmer air flowing through the engine is utilized to regulate the temperature of the engine, and to facilitate the evaporation of the nitrogen propellant, thereby creating a steady state condition that may last as long as the supply of liquid nitrogen.
