Ready-to-use real-time simulation system – customizable for your application

The Bloomy Simulation Reference System provides a hardware in-the-loop (HIL) test environment for dynamic, closed-loop testing of many aerospace and transportation control systems. The reference system integrates the computing, I/O, and software components needed for standalone use or to form the basis of a more complex test system.

The system is comprised of standard COTS platform components from National Instruments (NI), Bloomy, Virginia Panel, and others, and provides all of the critical simulation system elements in a standard rack enclosure.

For applications which require more highly-specialized test systems, the reference system provides a jump start, shortening schedules, reducing costs, and freeing your test engineering departments to focus on the differentiating technologies which make your product unique in the marketplace.

The representative set of I/O channels in the Bloomy Simulation Reference System meets the most common requirements for HIL test of line replaceable units (LRUs) such as electronic engine controllers (EECs), full-authority digital electronic controllers (FADECs), flight control computers (FCCs), environmental control systems (ECSs), and other control systems involving temperatures, pressures, positions and actuators. The standard configuration can be expanded or tailored to the exact I/O requirements for the specific type of unit under test. Customer-provided plant and actuator models are easily incorporated into the test system software for comprehensive test coverage.

Because this simulation system is based upon COTS components from industry-leading suppliers to the aerospace and automotive sectors, the initial and overall life-cycle costs are lower, and the system’s flexibility allows reconfiguration to maintain its value through multiple programs. The Bloomy Simulation Reference System includes industry-standard components from National Instruments (NI), Virginia Panel, Bloomy, and others, which are used in other HIL Test Systems including Bloomy’s FADEC/EEC Test Platform, the Environmental Control System Test Platform, and the Flight Control Test Platform.
