Abstract
A wave guide assembly for a control and diagnostic system for a machine, the wave guide assembly includes a housing defining an exterior surface and an internal cavity extending between distal ends. A wave guide is defined within the internal cavity. At least one open conduit is defined within the internal cavity providing a space for routing conductors through the housing. A fluid passage is defined within the internal cavity separate from the wave guide. A control and diagnostic system for a machine and a gas turbine engine are also disclosed.
Claims20
A wave guide assembly for a control and diagnostic system for a machine, the wave guide assembly comprising:
- a metal tube defining an exterior surface and an internal cavity extending between distal ends, the internal cavity of the meta tube including a cross-section defining a wave guide centered within the cross-section for providing a pathway for wave form signal communication between distal ends of the metal tube,
- at least one open conduit separate from the wave guide providing a space for routing conductors through the metal tube between distal end, and
- a fluid passage separate from the wave guide.
A control and diagnostic system for a machine comprising:
- a main transceiver mounted proximate the machine, the transceiver generating and receiving radio frequency waves corresponding to information for control and monitoring of engine operation;
- a wave guide assembly in communication with the main transceiver, the wave guide assembly including a metal tube including an interior surface and an internal cavity and an end fitting attached to each end of the metal tube, the internal cavity of the metal tube including in cross section a wave guide defining a transmission path for a wave form signal communicated with the main transceiver and a fluid passage separate from the wave guide defining a flow path for fluid;
- a fluid source in communication with the fluid passage of the wave guide assembly;
- and
- at least one remote transceiver attached to an end of the wave guide assembly and in communication with the main transceiver through a wave form signal communicated through the wave guide;
- and
- at least one fluid device in fluid communication with the fluid passage defined within the wave guide assembly.
A gas turbine engine comprising:
- a control and diagnostic system including:
- a main transceiver mounted proximate the gas turbine engine, the transceiver generating and receiving radio frequency waves corresponding to information for control and monitoring of engine operation;
- a wave guide assembly in communication with the main transceiver, the wave guide assembly comprising a metal tube including a cross-section defining an internal cavity and an end fitting attached to each end of the metal tube, the cross-section of the metal tube including a wave guide defining a transmission path for a wave form signal communicated with the main transceiver and a fluid passage separate from the wave guide that defines a flow path for fluid;
- a fluid source in communication with the fluid passage of the wave guide assembly;
- and
- at least one remote transceiver attached to an end of the wave guide assembly and in communication with the main transceiver through a wave form signal communicated through the wave guide;
- and
- at least one fluid device in fluid communication with the fluid passage defined within the wave guide assembly.
