Abstract
An injector includes an injector body that has at least an injection side surface. A plurality of passages extends within the injector body for injecting combustion fluids at the injection side surface. The plurality of passages include a first set of passages that has a first arrangement defining a first impingement point in space with regard to the injection side surface and a second, different set of passages that has a second arrangement defining a second impingement point in space with regard to the injection side surface. The first impingement point and the second impingement point are non-equidistant from the injection side surface
Claims17
An injector comprising:
- an injector body having at least an injection side surface;
- and
- a plurality of passages that extends within the injector body for injecting combustion fluids at the injection side surface, the plurality of passages including,
- a first set of passages having a first arrangement defining a first impingement point in space with regard to the injection side surface,
- a second, different set of passages having a second arrangement defining a second impingement point in space with regard to the injection side surface, and
- the first impingement point and the second impingement point are non-equidistant from the injection side surface.
A thruster comprising:
- a combustion chamber including an internal combustion zone;
- and
- an injector including an injector body having at least an injection side surface that bounds the combustion zone, the injector body including a plurality of passages that extends within the injector body for injecting combustion fluids into the combustion zone, the plurality of passages including,
- a first set of passages having a first arrangement defining a first impingement point in space with regard to the injection side surface,
- a second, different set of passages having a second arrangement defining a second impingement point in space with regard to the injection side surface, and
- the first impingement point and the second impingement point are non-equidistant from the injection side surface.
A method of controlling combustion of fluids, the method comprising:
- injecting a first stream and a second stream through respective passages of a first set of passages within an injector body such that the first stream and the second stream impinge at a first impingement point in space relative to an injector side surface of the injector body;
- and
- injecting a third stream and a fourth stream through respective passages of a second, different set of passages within the injector body such that the third stream and the fourth stream impinge at a second impingement point in space, the first impingement point and the second impingement point being non-equidistant from the injection side surface.
