Verification and Validation (V&V) Bench

Enhancements

Armstrong engineers have developed a new simulation test bench for V&V of software and hardware for the F/A-18 aircraft. The new V&V test bench replaces a bench that was developed more than 30 years ago.

Work to date: The new and more reliable bench is particularly innovative as it integrates reconfigurable software models for multiple aircraft components. These models enable high-fidelity simulations to be performed more easily and at significantly faster rates than were possible using the old hardware-centric test bench. In addition, this approach offers more accurate predictions of behavior.

Looking ahead: The team plans to begin developing the capability to interface with a wide variety of other computers, which in turn will enable simulations of other

aircraft such as the F-15 and systems with digital flight control systems.

Benefits

Rapid data collection: Operates at faster rates, allowing for more detailed modeling

Reconfigurable: Will accommodate other aircraft via software reconfigurations

Economical: Reduces the number of expensive flight tests

Applications

F/A-18 and F-15 aircraft

Electric aircraft motors and actuators

Control systems with redundant digital flight control systems

Flight and Ground Experimental Test Technologies

Armstrong conducts innovative flight research that continues to expand its world-class capabilities, with special expertise in research and testbed platforms, science platforms, and support aircraft. Re-searchers place particular emphasis on providing accurate flight data for research aimed at designing next-generation flight vehicles. Described here are research projects that are seeking to increase safety, reduce costs, and dramatically decrease testing and approval times. Armstrong's new verification and validation (V&V) simulation test bench is particularly innovative as it integrates reconfigurable software models for multiple aircraft components. These models enable high-fidelity simulations to be performed more easily and at significantly faster rates than are possible with hardware-centric test benches.
