An air-breathing rocket engine with an hourglass-shaped outer shell and an interior portion situated entirely within the front end of the outer shell. The interior portion includes a funnel-shaped intake that terminates in a floor and an inner front wall that forms a first circumferential gap between the inner front wall and the outer surface of the funnel-shaped intake. The intake has a central aperture that is in fluid communication with the throat and exhaust areas within the outer shell. A second circumferential gap is formed between the outer surface of the front inner wall and the inner surface of the front end of the outer shell and is in fluid communication with the throat and exhaust areas within the outer shell. One or more injector ports and one or more ignition ports are situated at the front end of the second circumferential gap.

An aerospace hybrid hypersonic propulsion system which has a common core airflow path through the engine combining subsonic, transonic, supersonics and hypersonic propulsion system and architecture in such a way that five known engine cycles known in the art are configured and connected to operate seamlessly with a hybrid electric and thermal cycle.

A combustor of a jet engine includes a fuel injector, an igniter for igniting a gas mixture of air and fuel, and a flame holder. The igniter is disposed in the flame holder. After an activation of the igniter, the igniter disappears, and a space after the disappearance functions as a flame-holding space.

An engine system that produces all required thrust for an aerospace vehicle from takeoff through space operation utilizing a turbo ram rocket exhaust nozzle and M-Spike rocket consisting of airbreathing and non-airbreathing propulsion apparatuses. The airbreathing system consists of a turbine engine, a ramjet or scramjet, and the non-airbreathing system is a rocket motor. The turbine engine consists of a turbojet or turbofan configuration. The air breathing turbine, ramjet or scramjet feature an air inlet mechanism, and combustion fuel. The non-airbreathing rocket system includes separate oxidizer system, and either a separate or same source of combustion fuel as the turbine. Airflow velocities in the turbine bypass duct, and burner system, include subsonic and supersonic velocities for ramjet or scramjet operation. The rocket engine utilize either cryogenic or a non-cryogenic fuel and oxidizer system.

A cover for an intake of an air-breathing engine in a missile is disclosed. The cover comprises a closure for closing the inlet so as to prevent ingress of debris; and a fastening attachable to an aircraft-mounted launcher and configured such that the cover remains attached to the aircraft on launch of the missile.

A jet engine for propelling aircraft, capable of providing thrust from rest to high speeds is provided. The engine has an axial compressor (16) or several axial compressors located on the same plane and is driven by a gas generator. At the outlet of the turbine there is a gasification chamber (23) into which more fuel is injected. Combustion of the gases from the gasification chamber is performed in two combustion chambers (18) with a rectangular cross-section, separated by a central body (10). The exhaust of the gases is performed in nozzles, each with a square convergent/divergent cross-section (19) and (21). The cross-section of the throats (26) can be adjusted by means of two mobile elements (20). The final section of the central body (10) forms a wedge-shape (27), enabling the continued expansion of the exhaust gases.
