Solution Approach 1:

The patent applies parameter changes by transitioning from conventional combustion to detonation combustion, fundamentally changing the combustion parameters (pressure, temperature, reaction rate) to achieve superior heat production efficiency. The detonation wave creates extremely high temperature and pressure conditions that conventional combustion cannot achieve, directly resolving the contradiction between heat production efficiency and energy loss.

Inventive Principle:

Solution Approach 2:

The rotating detonation combustor utilizes periodic detonation waves that travel around the annular combustion chamber, creating cyclic high-energy events. This periodic action allows continuous heat generation with each detonation cycle, improving overall system productivity while maintaining energy efficiency through the self-sustaining nature of the detonation process.
