Abstract
An additively manufactured attritable engine includes a compressor section, a combustion section, a turbine section, and an engine case wall, which surrounds the compressor section, the combustion section, and the turbine section. The engine case wall includes a first cavity embedded in the engine case wall that defines an injector that is in fluid communication with the combustion section. The engine case wall includes at least one second cavity embedded within the engine case wall and defines at least one cooling channel that is in thermal communication through the engine case wall with the injector.
Claims8
A method of testing a fluid dispensing system in an attritable engine that includes a fuel line and an N number of injectors, the method comprising:
- injecting a cooling fluid into a cooling hole for each of (N−1) injectors;
- inducing a first phase change to a flow test fluid in each of the (N−1) injectors, preventing flow through each of the (N−1) injectors;
- and
- measuring a first flow rate of the flow test fluid through an unblocked injector.
