Jacobs Engineering Group Inc. received a contract from NASA to provide engineering, procurement, and construction management services to upgrade the Icing Research Tunnel at Glenn Research Center in Ohio. Jacobs will design, build, and commission a new integrated refrigeration system comprised of primary refrigeration equipment, a secondary coolant loop, and a new heat exchanger. Jacobs will also design and construct a single-story, 70- by 120-ft building to house the new refrigeration system. The contract value is estimated at $16 million. Jacobs' solution will provide the ability to achieve an optimum testing environment for conducting ground, de-icing, and anti-icing research on military and commercial aircraft in uniform simulated icing conditions at airspeeds of up to 350 knot.
