According to defense Commentary website reported on November 6, 2012, the U.S. Navy has a very strong dependence, the navy has been looking for new methods to improve the type of engine fuel combustion efficiency for the gas turbine propulsion. The scientists from the Naval Research Laboratory (nrl) is currently studying the complexity of the physical principles of the rotating detonation engine (rotating detonation engine, rde), rotating detonation engine can be significant cost savings by reducing the fuel consumption of the gas turbine.

The majority of the U.S. Navy's aircraft gas turbine propulsion, similar to the engine used in the basic principles and civil aircraft engine. At the same time, the Navy is also dependent on gas turbine engine to provide the impetus for a large number of warships and electricity.

Even if future warships are "all-electric" propulsion system, these warships still need to gas turbine propulsion systems and other critical systems need to provide electricity. Developed a able to meet both the needs of the Navy's warships, and also be able to provide the engine of fuel efficient utilization, the primary task of the researchers.

U.S. Navy gas turbine has attractive, the reason is that the gas turbine, small size, big power, completely independent, and easy to maintain. U.S. Navy currently used by the gas turbine based on the Brayton thermodynamic cycle, the air in the engine compression and combustion is performed under a constant pressure in the fuel mixture, and outputs the propulsive power or electricity. In order to significantly improve the performance of gas turbine engines, researchers need to jump out of the Brayton cycle to develop new, more innovative alternatives.

Naval Research Laboratory scientists believe that the alternative detonation cycle gas turbine Brayton cycle is a viable option. Naval Research Laboratory in the past decade has been engaged in research detonation engine, and achieved good results in the research of pulse detonation engine (pulse detonation engine, pde).

Rotating detonation engines utilize the detonation cycle gas turbine engine can achieve higher fuel efficiency. Naval Research Laboratory scientists have rotating detonation engine simulation model is established on the basis of the previous conventional detonation research. The scientists believe that the rotating detonation engine to increase the power output by 10%, while a 25% reduction in fuel consumption.
