Virtual Laboratory Expands nasa Research

NASA has successfully concluded tests on a computer-generated virtual laboratory that will allow researchers, located anywhere in the world, to study potentially dangerous aircraft and spacecraft situations without risking human life.

The lab can enable research organizations to collaborate long­distance without having to be physically present at the world's larg­est flight simulator at Ames Research Center, California. It could also be used by universities, research laboratories and industry to develop a wide variety of products beyond the aerospace field. Fu-

ture uses of the laboratory being considered include designing new spacecrafts and training astronauts.

The simulator is able to move airplane and spaceship cockpits in all directions, including 60 feet vertically and 40 feet horizon­tally. There are five interchangeable cockpits that are used to simu­late the Space Shuttle, helicopters, airplanes and other aerospace vehicles.

The simulator creates a convincing environment for a pilot and is controlled by computers programmed to represent each aircraft proposed.

Computers calculate correct aircraft response when a pilot changes simulator cockpit controls. In real time, responses by the simulator include cockpit motion, images in the windshield, sounds and control readouts. Simulations are monitored from the control lab at ARC. The virtual laboratory and the «world» it cre­ates exist partly in computer memory and other physical gear.

Recently, astronauts made simulated Space Shuttle landings using a huge motion simulator at ARC while NASA engineers in Houston monitored the sessions using the three-dimensional «world» that includes video screens, computer video, two-way video conferencing, remote data access and a pilot's out-the-window scene.
