Hamilton Sundstrand’s propeller modernization program makes strides, offers operation and support benefits to C-130 users

Hamilton Sundstrand Corporation’s NP2000 propeller successfully completed performance testing with the U.S. Air Force on C-130H aircraft, and is nearing completion of operational evaluation by the New York Air National Guard on LC-130 aircraft, marking two more milestones in Hamilton Sundstrand’s propeller modernization program. Hamilton Sundstrand is a subsidiary of United Technologies Corporation (NYSE: UTX).

The testing with the U.S. Air Force covered complete aircraft and propeller performance gains on C-130H aircraft, after replacing the Hamilton Sundstrand four bladed 54H60 propeller with the modern NP2000 eight bladed propeller. As a result of operational evaluation on LC-130 aircraft for the past two years, the New York Air National Guard has requested the NP2000 propeller as a permanent modification for their fleet of LC-130.

The NP2000 propeller system offers many benefits to C-130 users, including shorter take-off roll, improved climb, quieter operations, and lower operating and support costs.

“Hamilton Sundstrand is very proud of the progress we are making with our propeller modernization program,” said Robert Schechtman, business development manager of Hamilton Sundstrand’s propeller systems business. “This testing has clearly identified the benefits to the operator in terms of aircraft performance and improved reliability and maintainability of the propeller system.”

Earlier this year, Naval Air Systems Command (NAVAIR) awarded Hamilton Sundstrand a contract for the procurement and installation of as many as 25 electronic propeller control system (EPCS) aircraft kits for the U.S. Navy Reserve’s C-130T aircraft and the U.S. Air National Guard’s LC-130H aircraft. EPCS kits replace 54H60 propeller mechanical controls with a system based on digital computer software and are part of Hamilton Sundstrand’s propeller modernization program, which can be applied to NP2000 propellers in the future.
