MetaVR Visuals Used in Northrop Grumman Aerial Refueling Operator Simulator

Northrop Grumman, bidder for the US airforce tanker program, uses MetaVR visuals in its aerial refueling simulation. In support of its KC-45 Advanced Multi-role Tanker Transport (AMTT) proposal, Northrop Grumman built an Aerial Refueling Operator (ARO) simulator to use as an advanced-concept demonstrator. For this proposal, Northrop Grumman Corporation teamed with EADS to compete for the U.S. Air Force’s next-generation air refueling tanker, to replace the aging KC-135 Stratotanker.

Using the MetaVR™ Virtual Reality Scene Generator™ (VRSG™) as its 3D visualization system, the advanced-concept demonstrator traveled to the 2005 Airlift/Tanker Association (A/TA) in Nashville, Kentucky, and to the 2006 Air Force Association (AFA) Air Warfare Symposium in Orlando, Florida. The simulator is used to promote discussion and evaluation of future refueling concepts, and to provide an interactive refueling simulation experience.

Off-the-shelf functionality available in MetaVR’s VRSG software enabled the simulator part of the demonstrator to be constructed in a short amount of time. By using DirectX, a true 3D stereoscopic display was implemented without additional software development. The simulation flies over MetaVR’s round-earth formatted (Metadesic) North America 3D terrain.

The software simulates both the AMTT’s flying boom operations and hose and drogue refueling operations, including features such as Air Refueling (AR) flight patterns, collision modeling, and refueling contact modeling. This version of the ARO simulator models fifteen boom receivers and ten drogue receivers.
