AFRL F-16 X-DTTs Delivered to Aviano AFB, Italy, Upgraded With MetaVR Visuals
The Air Force Research Laboratory, Warfighter Readiness Research Division, (AFRL) updated their F-16 Experimental Deployable Tactics Trainer (X-DTT) simulators in 2010 to use MetaVR visuals and portable immersive domes. The F-16 X-DTTs are deployable, medium fidelity, in-theater training systems for keeping the warfighter proficient between missions.
For this update, the AFRL lab purchased 26 MetaVR™ Virtual Reality Scene Generator™ (VRSG™) licenses to replace its existing SDS International AAcuity PC-IG systems for the simulators. The MetaVR software runs on the existing image generator hardware with no changes required.
The X-DTT photographs on this page show the upgraded simulators during integration and testing prior to the delivery to the US Air Force in Aviano, Italy.
Each F-16 X-DTT has six projected views on the partial dome in addition to a sensor view. Each system can be used as a standalone training tool or networked with other simulators to participate in larger exercises.
The domes are constructed of fiberglass in order to provide the best possible surface that minimizes seams and reduces blemishes. Each dome is a 3.0-meter (diameter) display, providing 220-degree horizontal field-of-view (FOV) x 90-degree (+60/-30) FOV. The visual solution includes six Projection Design FL32 WUXGA projectors with wide-angle lenses; each projector has 1920 x 1200 pixel resolution. The integration between MetaVR VRSG and Scalable Display Technologies' EasyBlend FX software provides for geometry warp and the auto alignment (edge blend) of all VRSG channels, resulting in a seamless image. The system has an average blended resolution of 11.5 million pixels, equals 4.8 arc-min/OLP. An integrated adjustable truss system supports all the projection equipment, auto alignment cameras, and the HUD projector. (The separate HUD projector is not shown in the photographs.)
AFRL is a research organization chartered to develop state-of-the-art training technologies and methods that support the 21st century warfighter. The primary goals of the research division are to develop or evaluate various technologies as training and research tools and to investigate training effectiveness through assessment in a distributed mission operations (DMO) environment. The training research environment at AFRL is comprised of various simulation systems and performance measurement tools that provide warfighters with opportunities to develop and refine their knowledge and skills required to be successful in a combat environment.
The goal of the X-DTT simulators is to provide pilots with the ability to practice and maintain air combat skills in forward operating locations. These simulators are intended for use by deployed pilots who generally perform missions in support of real world operations with limited or no sorties or flying range space available for training opportunities and who might incur deficiencies in critical mission skills needed for other theaters.
The medium-fidelity X-DTT simulator consists of an F-16 Block 30 aircraft shell with the actual F-16 Operational Flight Program (OFP) and high-fidelity aircraft stick and throttle. These simulators provide the essential F-16 cockpit switches on a touch-screen LCD in front of the pilot.
The updated F-16 X-DTT simulators were delivered to and installed at the Aviano Air Base, Italy, in autumn 2010.
Background material for F-16 X-DTT at AFRL is extracted from the paper Impact of Visual Scene Field of View on F-16 Pilot Performance from the Proceedings of the Human Factors and Ergonomics Society Annual Meeting 2007.
