Abstract
A subsonic diffuser is provided for decelerating airflow provided to an air-breathing engine. The subsonic diffuser includes a duct having an inlet and an outlet, and a splitter. The cross-sectional area of the duct increases from the inlet to the outlet, and the splitter delineates a plurality of passageways through the duct. During operation, the passageways divide and decelerate a subsonic airflow supplied to the subsonic diffuser, and the subsonic diffuser delivers a decelerated airflow to the air-breathing engine.
Claims29
A subsonic diffuser, comprising:
- a duct having an inlet and an outlet, wherein the cross-sectional area of said duct increases from said inlet to said outlet, and
- a splitter in said duct, said splitter dividing the outlet into a plurality of outlet ports.
A method for decelerating airflow provided to an air-breathing engine using a subsonic diffuser, the method comprising:
- dividing a subsonic airflow supplied to the subsonic diffuser between two passageways;
- decelerating the airflow in each of the two passageways;
- and
- delivering the decelerated airflow to the air-breathing engine.
A method of designing a subsonic diffuser, the method comprising:
- providing the subsonic diffuser with a specified number of splitters;
- arranging each of the specified number of splitters to provide at least two passageways through the subsonic diffuser;
- and
- dimensioning the length of the subsonic diffuser according to the specified number of passageways.
A subsonic diffuser, comprising:
- a duct including an inlet and an outlet, and
- a means for splitting an airflow between said inlet and said outlet.
A subsonic diffuser, comprising:
- a duct having an inlet and an outlet, wherein the cross-sectional area of said duct increases from said inlet to said outlet, and
- a splitter in said duct extending from said inlet partially through the length of said duct, said splitter dividing the inlet into a plurality of inlet ports.
A subsonic diffuser, comprising:
- a duct having an inlet and an outlet, wherein the cross-sectional area of said duct increases from said inlet to said outlet, and
- a splitter in said duct extending partially across said duct.
