Sierra Nevada Corp. has selected Parker Aerospace Gas Turbine Fuel Systems division’s thermal-management equipment to cool and heat its autonomous landing system (HALS) on Sikorsky UH-60 Black Hawk helicopters. Sierra Nevada has a contract to fulfill the degraded visual environments (DVE) operational-needs statement issued by the U.S. Army aviation-networks mission-planning program directorate.

The HALS system combines real-time, three-dimensional images with satellite digital-terrain imagery and DVE-specific guidance symbols for takeoffs, approaches and landings in fog, “brownouts” and other reduced-visibility conditions. “The systems will be installed [for use] in extremely harsh environments with high levels of vibration, sand, dust and heat,” said SNC HALS program manager Bob Lombard.

Among its myriad products, Parker Aerospace provides many items for the Rolls-Royce Trent XWB engine that will power the Airbus A350. Components include: the pneumatics system for engine controls, including intermediate- and high-pressure (IP and HP) compressor bleed, cooling-air control, engine-section stator and nacelle anti-ice, pressure regulator, solenoid actuators and check valves, as well as low-pressure and IP and HP turbine-case cooling valves and actuators; the engine build unit, including hydraulic fluid conveyance to transmit hydraulic power between engine-mounted pumps and the aircraft; the oil system, including main pump, surface-cooler valve, variable-frequency generator cooler valve and front-bearing housing valve; and the combustion system high-temperature flexible hoses.

 

New Management

Roger Sherrard has been appointed as the new president of Parker Hannifin subsidiary Parker Aerospace (Hall 4 Stand A18). He will replace Bob Barker, who is retiring after 39 years with the company. Meanwhile, Greg Crowe has been named Parker Aerospace operations vice president and Frank Dubey has been appointed vice president and general manager of Parker Aerospace Control Systems.

Sherrard will be responsible for fiscal and operational aspects of the group’s seven divisions. Most recently, he was president of Parker Hannifin’s automation group, leading development, manufacturing and marketing of pneumatic and electromechanical systems and machine- and factory-automation components.

In his new role, Crowe will take responsibility for finance and operations at Parker Aerospace’s Fluid Systems, Control Systems and Stratoflex Products divisions, from his previous position as fluid-systems vice president and general manager.
