Parker Aerospace, a business segment of Parker Hannifin Corporation (NYSE: PH), the global leader in motion and control technologies, has been selected by Sierra Nevada Corporation (SNC) for its Helicopter Autonomous Landing System (HALS) program.

Parker Aerospace's thermal management systems (TMS) organization will provide SNC with thermal management solutions that enable HALS to be initially integrated on UH-60 Black Hawk helicopters. SNC was awarded a contract to fulfill the degraded visual environments (DVE) operational needs statement issued by the US Army Aviation Networks Mission Planning Program Directorate. SNC's HALS combines real-time 3D imagery with digital terrain map, satellite imagery, and DVE specific guidance symbology to provide a complete DVE solution for takeoff, approach, and landing operations in fog, brownouts, and other DVEs. The initial HALS deliveries will be used in support of Operation Enduring Freedom.

"Parker is supplying us with the thermal management systems that will provide cooling and heating for our critical HALS electronics," said Bob Lombard, SNC's HALS program manager. "The systems we will be supplying the Army will be installed in extremely harsh environments with high levels of vibration, sand, dust, and heat," added Lombard. "We have been very happy with Parker's thermal management products and support over the last several years as we have progressed through a series of HALS development and flight testing phases."

Parker Aerospace's TMS organization is located in Liberty Lake, Washington, and Mentor, Ohio, and is part of the Parker Aerospace Gas Turbine Fuel Systems Division. The team specializes in thermal management systems, including liquid-cooled environmentally sealed enclosures, cold plates, and heat rejection products for harsh environments in defense, aerospace, and industrial applications. The TMS organization works with other Parker divisions to provide motors, controllers, pumps, valves, quick disconnects, and other fluid distribution products to provide complete thermal management systems solutions to military and aerospace customers.
