Standing normal detonation jet engine and method of producing a standing normal detonation wave

A method of producing a standing normal detonation wave in an engine, comprising:

• injecting an oxidizer and a fuel into a detonation chamber at a stoichiometric oxidizer/fuel equivalence ratio of 0.1 to 3.0;
• igniting the fuel to create a detonation wave in the detonation chamber;
• directing the oxidizer into the detonation wave at a speed that is equal to or 10% greater than a CJ consumption speed of the detonation wave;
• and
• maintaining the oxidizer/fuel equivalence ratio and the speed of the oxidizer relative to the CJ consumption speed of the detonation wave thereby causing the detonation wave to reside in a generally normal orientation relative to a longitudinal axis of the detonation chamber.

A method of producing a standing normal detonation wave in an engine, comprising:

• injecting an oxidizer and a fuel into a detonation chamber;
• igniting the fuel to create a detonation wave in the detonation chamber;
• adjusting a stoichiometric oxidizer/fuel equivalence ratio between 0.1 to 3.0 until the detonation wave has a CJ consumption speed between about Mach 4 and about Mach 6;
• directing the oxidizer into the detonation wave at a speed ratio that is between 1 and 1.1, wherein the speed ratio is a ratio of a speed of the oxidizer relative to the CJ consumption speed of the detonation wave;
• and
• maintaining the oxidizer/fuel equivalence ratio and the speed ratio to cause the detonation wave to maintain a generally normal orientation relative to a longitudinal axis of the detonation chamber.
