Abstract
A diffuser may comprise an inlet and an outlet. The inlet may comprise an arcuate shape. The outlet may comprise an annular shape. The diffuser may transition from the arcuate shape at the inlet to the annular shape at the outlet. The diffuser may comprise a radially inner wall and a radially outer wall disposed opposite the radially inner wall. The radially inner wall and the radially outer wall may partially define a duct.
Claims19
A diffuser, comprising:
- a radially inner wall including an arc angle, wherein the arc angle increases as the radially inner wall extends axially;
- a radially outer wall disposed radially outward from the radially inner wall;
- a first side wall disposed between the radially inner wall and the radially outer wall;
- and
- a second side wall disposed between the radially inner wall and the radially outer wall, the second side wall disposed opposite the first side wall, wherein:
- the radially inner wall, the radially outer wall, the first side wall and the second side wall define a duct therebetween, and
- the first side wall and the second side wall merge at an outlet of the duct.

A diffuser, comprising:
- an inlet comprising a chin portion defining a duct, the inlet defined by a first side wall, a second side wall, a radially inner wall and a radially outer wall;
- an outlet disposed axially opposite the inlet, the outlet defining an annular ring shape, the outlet defined radially between the radially inner wall and the radially outer wall of the diffuser;
- and
- a transition portion disposed between the inlet and the outlet, wherein the transition portion transitions from the chin portion at the inlet to the annular ring shape at the outlet wherein the first side wall and the second side wall merge at the outlet of the duct.
1 more element
A vehicle assembly, comprising:
- an airframe;
- a rotating detonation engine disposed within the airframe at an aft end;
- and
- a diffuser disposed in the airframe, the diffuser comprising:
- a radially inner wall and a radially outer wall disposed radially outward from the radially inner wall, the radially inner wall and the radially outer wall partially defining a duct therebetween;
- an inlet having an arc angle of the radially inner wall and the radially outer wall between 20 degrees and 120 degrees, the inlet defined by the radially inner wall, the radially outer wall, a first side wall, and a second side wall;
- and
- an outlet disposed proximate the rotating detonation engine, wherein the first side wall and the second side wall merge at the outlet.
