ABSTRACT:
A system or method of propelling a vehicle with a multimodal propulsion system is provided. This multimodal propulsion system includes a primary inlet, a high-pressure gas generator, a gas generator exhaust system, a secondary fluid inlet, and a propulsion exhaust system. The primary inlet receives an incoming fluid flow that is provided to the high-pressure gas generator. The high-pressure gas generator coupled to the primary inlet produces a high-pressure exhaust from the incoming fluid flow. The high-pressure gas generator exhaust and secondary inlet couple to the propulsive exhaust system which mixes the two flow streams. The secondary flow may be gaseous or liquid fluid flow such as air flow for airborne flight and water for waterborne operation. The mixed fluid flow is expelled by the propulsive exhaust system that can propel the vehicle.
