AI Technical Summary
Technical Problem
Inadequate fuel/air mixing in existing rotary detonation burners leads to inefficiency, and detonation in a single annular space presents thermomechanical design challenges.
Method used
A rotary detonation burner is designed, which uses radial inner walls and radial outer walls to define an annular chamber, and divides the burner inlet end into multiple mixing zones by at least one baffle, and sets multiple oxidizer and fuel inlets to realize the generation and transmission of multiple pairs of detonation waves.
Benefits of technology
It improves the efficiency and operational freedom of the burner, reduces the challenges of thermomechanical design, and enhances the propulsion and energy conversion efficiency of combustion products.

Abstract
The present disclosure relates to a rotary detonation combustor including a front wall, a radially inner wall, and a radially outer wall. The front wall is disposed at an inlet end of the rotary detonation combustor. The radially inner wall surrounds a longitudinal axis and extends downstream from the front wall to an outlet end of the rotary detonation combustor. The radially outer wall extends downstream from the front wall to the outlet end and surrounds the radially inner wall to define at least one annular cell between the radially inner wall and the radially outer wall. At least one partition is proximate the inlet end and defines at least two mixing zones. A plurality of oxidizer inlets and a plurality of fuel inlets are disposed at the inlet end in fluid communication with the at least two mixing zones.
