A rocket engine for manned or unmanned space flight and atmospheric flight uses an elongated fuel structure that is external to the combustion chamber and that is fed into the combustion chamber during operation of the rocket. The elongated fuel structure includes propellant elements and may include coolant elements and gas generating elements as well. The elongated fuel structure of one embodiment is a ribbon. The ribbon is fed between two opposed wheels of the fuel pump, which seal the engine from escaping gases while permitting the elongated fuel structure to be drawn into the engine. The opposed wheels may serve to activate the gas generating elements, so that gas pressure generated thereby drives the propellant elements into the combustion chamber of the rocket engine. The activation of the gas generating elements also provides coolant to the engine from the coolant elements, in one embodiment.
