A pulse detonation rocket engine, having at least two detonation chambers. The rocket propelled vehicle includes at least one fuel delivery system in fluid communication with each of the at least two detonation chambers, and at least one oxidant delivery system in fluid communication with the detonation chambers, along with fast-acting valves to inject fuel and oxidant controlledly into the chambers. An ignitor in each of the detonation chambers intermittently initiates detonation of a fuel and oxidant mixture in the chamber, in a controlled cycle, to provide motive force. Also provided is a combined cycle engine, able to operate in air breathing mode, oxidant augmented mode, and as a rocket engine. The combined cycle engine includes at least one detonation chamber, and may include a plurality of such chambers. The invention further provides methods of intermittently detonating sequentially created fuel and oxygen mixtures in these engines, and methods of using these engines.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.] A method of sequentially detonating a fuel and oxidant mixture in a rocket engine, the method comprising:(a) commencing a pulse detonation cycle by creating a detonable fuel and oxidant mixture in a first of a plurality of detonation chambers of a rocket engine, by controlling the amount of fuel supplied by a fuel injector, and supplying an amount of oxidant sufficient to produce a detonable fuel-oxidant mixture to the chamber;(b) igniting the fuel and oxidant mixture in the first detonation chamber to cause a detonation;(c) expelling combustion products of the detonation from the detonation chamber through a nozzle;(d) creating a buffer composition in the first detonation chamber after igniting a fuel and oxidant mixture from a previous cycle and before commencing a next pulse detonation cycle; and(e) controlling timing sequence of oxidant and fuel injection, and ignition by a programmable digital signal processor;whereby continuous pulsed detonation is achieved by performing steps (a) through (d) in a predetermined sequence under control of the digital signal processor for each of the plurality of detonation chambers, and by repeating the cycle commencing with step (a) for the first detonation chamber.
