  1. Rotation Detonation Engines work on basic thermodynamics: the higher the starting burn, the more efficient the engine ought to be. What stops the highest temperatures: materials. Diesels have to use inter-coolers after the turbo-boost just to save the engine. From a purely thermodynamic point of view, the ideal engine wouldn't have one. (Highest efficiency would degrade unit specific output -- less HP.) RDE hopes to fuse the episodic burn seen in ICE engines -- where the burn temperature is quite high compared to the containment metals -- with the flow through seen in open Brayton cycle engines. ( gas turbines ) If RDE geometry can be solved, the Big Change would first show up in the use of MUCH cheaper metals for turbines. RDE tech would not change the nature of after-burners. They'd still be fuel pigs. For ultra-speed applications, we've already hit the wall in terms of materials. RDE -- it is hoped -- would allow super exotic performance when exotic materials were employed. It'd be like a rocket motor that does not need regenerative cooling. (The latter chills expansion gases that you really wish to keep super hot.) Such wasted thrust is most evident in the classic NASA footage of the Saturn V at lift off. A skirt of un-burnt propellant shoots down -- hiding the flame -- until about 2 meters below the nozzles. Then the gas bursts blindingly white hot. Of course, the whole idea of using naval air against Red China is a joke. As seen in 1945, carriers sail close only to deliver the coup de grace. Red China will be defeated by radio announcement. Once the USN broadcasts that merchants sailing to Red China are suicidal -- no-one will do so. There will be no repetition of the Battle of the Atlantic. (1939-1945) Red China's war industries will collapse faster than Putin's.
