An engine assembly is configured to exceed Mach. The engine assembly has a casing mechanically coupled to a jet engine such that ducting exists between the casing and the jet engine. The jet engine further includes a low pressure compression stage configured to compress a gasses. A high pressure compression stage is connected to the low pressure compression stage and configured to further compress the gasses. A combustion stage is connected to the high pressure compression stage and configured to heat the gasses to three thousand degrees Fahrenheit by back pressure. A low pressure turbine is connected to the combustion stage and configured to utilize energy in the gasses so that there is very little emission from the low pressure turbine. A shaft is connected to the low pressure turbine and configured to turn as a result of the low pressure turbine. A ducted impeller has blades wherein the blades are widest at a blade tip, narrowing down to a hub, while not over lapping and beginning with a rotation of at least 45 degrees to the shaft and of a steeper angle going toward the hub to create an even air pressure along an entire length of each blade.
