Paris 2011: Boeing Adds Hamilton Sundstrand to KC-46 Tanker Team

Boeing has added Hamilton Sundstrand to its team of suppliers on the KC-46 aerial tanker, awarding it a contract to supply its environmental-control system, electric-power generation system, emergency ram-air turbine system, fans and engine bleed-air system, engine controls and accessories, bleed-air leak detection system and the engine/APU fire detection and overheat detection system.

The equipment either replicates the hardware or is based on the systems the company supplies for the Boeing 767-400 airliner. However, adoption of some of the systems on the KC-46 will require software modifications, said Hamilton Sundstrand.

Separately, the Windsor Locks, Connecticut-based United Technologies subsidiary recently finished performance testing of its NP2000 propeller with the U.S. Air Force’s C-130H transport and the New York Air National Guard has nearly finished operational evaluation on LC-130s.

The testing with the USAF covered complete aircraft and propeller performance gains on C-130Hs, after replacing four-bladed Hamilton Sundstrand 54H60 propellers with modern, eight-bladed NP2000s. Meanwhile, after a two-year evaluation, the New York Air National Guard requested a switch to the NP2000 propeller as a permanent modification for its fleet of LC-130s.
