to the Virtual Tour of the NASA Glenn Icing Research Tunnel! This
Web site was developed to accompany the Icing Research Tunnel (IRT)
series of videoconferences. The videoconferences introduce the NASA Glenn Icing
Research program and provide a tour of
Research Tunnel. The site includes
background information on the history of the Icing Research Tunnel,
research that is conducted in the IRT, images of the main components
of the tunnel, archived video from the videoconferences, and Web-based
The NASA Glenn
IRT is the oldest and largest refrigerated
icing wind tunnel in the world. It has been used to research ice detection
systems and develop icing technologies used on many of today's aircraft.
The IRT is able to duplicate nature's icing conditions that aircraft
typically encounter. The conditions are simulated using a refrigeration
plant and a spray bar system that generate an icing cloud in the tunnel.
The IRT has played a role in developing, testing, and certifying methods
to prevent ice buildup on aircraft.
Today the Icing Research
Tunnel is used to investigate:
- Low-powered electromechanical
deicing and anti-icing fluids for use on the ground
- Deicing and anti-icing
research on STOVL rotor systems and certification.
- Certification of ice
protection systems for military and commercial aircraft.
The IRT is capable of producing
airspeeds from 50 to 400 mph and temperatures as
low as -20o F.
It has ten spraybars with
one hundred nozzles that produce supercooled water droplets that can
form a 4 ft high by 6 ft wide ice cloud.
Branch at NASA Glenn Research Center
performs research activities related to the development of methods for
evaluating and simulating the growth of ice on aircraft surfaces, the
effects that ice may have on the behavior of aircraft in flight, and
the behavior of ice protection/detection systems. The Branch uses the
Icing Research Tunnel and the Twin Otter Icing Research Aircraft to
