Abstract
The invention is a propulsion system. In detail, the invention comprises a hollow housing having a longitudinal axis and an inlet end and an exhaust nozzle end. A shaft is rotatively mounted along the longitudinal axis within the housing, extending from the inlet end to the exhaust nozzle end. A fan is attached to one end of the shaft in proximity to the inlet end of the housing. A turbine, having a plurality of blades, is attached to the opposite end of the shaft in proximity to the exhaust nozzle end of the housing. A solid propellant rocket motor is detachably mounted to the housing, having a thrust axis alignable with the longitudinal axis of the housing such that, when the motor is ignited, at least a portion of any exhaust gases therefrom are intercepted by the blades of the turbine for driving same.
