Abstract:
A Centerline Compression Turbofan Engine reconfigures the current technology eliminating the shaft and placing the combustor at the intake of the engineTurbine blades mounted on the inside of consecutive rings are curved and angled so that they compress air towards the centerline and backward along the axis of the engine as they rotate. High speed exhaust gasses from the combustor coming into contact with the turbine blades provide the rotational drive for each turbine blade array.Exhaust gasses from the combustion chamber and air from the intake are compressed through consecutively smaller turbine blade arrays along the entire length of the engine until it exits the variable exhaust nozzle.Said configuration produces a jet of a high speed exhaust gas for propulsive purposes.
