Abstract
An aircraft engine emulator comprises a housing; at least one actuator or emulated actuator disposed within the housing; at least one sensor or emulated sensor disposed within the housing; and a wired connection configured to connect the at least one actuator or emulated actuator and the at least one sensor or emulated sensor for communication with components on board an aircraft, wherein the aircraft engine emulator is configured to take the place of an engine to the components on board an aircraft that has at least one missing or non-functional engine.
Claims15
An aircraft engine emulator comprising:
- a housing;
- at least one actuator or emulated actuator disposed within the housing;
- at least one sensor or emulated sensor disposed within the housing;
- and
- a wired connection configured to connect the at least one actuator or emulated actuator and the at least one sensor or emulated sensor for communication with components on board an aircraft,
- wherein the aircraft engine emulator is configured to present to functionality of components on board an aircraft having at least one missing or non-functional engine, a substitution for non-operating engine states.
An aircraft engine emulation method comprising:
- emulating an actuator interface of an aircraft engine with at least a first component disposed within a non-engine portable housing;
- emulating a sensor interface of the aircraft engine with a second component disposed within the non-engine portable housing;
- and
- connecting the first component and the second component for communication with an aircraft that has at least one missing or non-functional engine, so as to take the place of the at least one missing or non-functional engine for purposes of interfacing with other components on board the aircraft but not for propelling the aircraft.
A method comprising:
- determining which aircraft systems depend on an engine under manufacturing or ground maintenance conditions;
- identifying which signals are exchanged between these systems and the engine;
- identifying sensors, actuators and controllers involved;
- identifying electrical interconnection of components;
- measuring electrical quantities of the sensors (resistance, impedance, and capacitance);
- defining which sensors will be used and which sensors will be replaced with non-sensor electrical components;
- packing all components in an external box to build a GSE;
- and
- building an interface wiring based on engine electrical interconnection diagrams.
