Instrumentation

Health Utilization and Monitoring Systems (HUMS) and Test Instrumentation can be accomplished by use of Modular Avionics. By using a modular architecture, a test setup has high flexibility to adapt to the needs of the test as they evolve. As these test avionics may represent flight avionics, consider matching the flight configuration to minimize re-engineering and to get full system test heritage.

Test Configurations:

• HUMS - Integrated with flight avionics: Add modules to the avionics system to incorporate additional monitoring and/or control needed to perform system or sub-system tests.

• Standalone: A standalone module is optionally connected to a network and features internal data storage and a RTC battery for intermittent offline operations. The unit can be signaled from control inputs (buttons) and has status signals (LEDs) to inform user of operating state. Once configured, standalone modules just need power and something to monitor and/or control.

• Lab Bench Chassis: A basic frame supporting power input, data distribution, data recording, and network slots available for modules used in testing. This is suitable around 500Mbps of total throughput and 100 watts of total instrumentation power.

• Field Chassis: A portable test chassis similar to the Lab Bench Chassis with a carry case for easy handling, bulkhead connectors for rugged cable disconnects, internal battery for offline operation, ISM communications mesh for remote management, and GNSS for precision time and location of the portable unit.

Sensors: Thermocouple, RTD, Thermistor, Bridge (load cells, strain, pressure), ratiometric, IEPE, Cameras, Inertial, encoders, etc.

Controls: Valves, small actuators, lights, servos, etc.
