Abstract
A pressure simulator is disclosed. The pressure simulator may include a supply inlet, a venturi coupled to the supply inlet by a supply conduit, the venturi including a vacuum output, and a first simulator output coupled to the vacuum output by a vacuum conduit. The venturi is configured to receive a compressed gas from the supply inlet and to provide a vacuum to the first output via the vacuum conduit.
Claims20
A pressure simulator, comprising
- a supply inlet,
- a venturi coupled to the supply inlet by a supply conduit, the venturi including a vacuum output, and
- a first simulator output coupled to the vacuum output by a vacuum conduit,
- wherein the venturi is configured to receive a flow of compressed gas from the supply inlet and to provide a vacuum to the first simulator output via the vacuum conduit.

A portable apparatus for testing an electronic engine controller of a gas turbine engine, comprising:
- a housing;
- a power supply module mounted within the housing;
- an interface test adaptor mounted within the housing;
- and
- a pressure simulator mounted within the housing, comprising
- a supply inlet,
- a venturi coupled to the supply inlet by a supply conduit, the venturi including a vacuum output,
- a first simulator output coupled to the vacuum output by a vacuum conduit,
- a first high pressure conduit connecting the supply inlet to the first output,
- a first switch positioned downstream of the supply inlet and upstream of the venturi, the first switch configured to selectively connect the supply inlet to one of the venturi and the first simulator output,
- wherein the venturi is configured to receive compressed gas from the supply inlet and to provide a vacuum to the first simulator output via the vacuum conduit and wherein the first simulator output is configured to supply one of a vacuum input and a positive pressure input to a sensor of an electronic engine controller.
