August 26, 2010 - Pratt & Whitney has completed assembly on its first PurePower PW1524G engine for the Bombardier C Series aircraft and will deliver the engine to the company’s West Palm Beach, Florida, facility later this month to initiate testing.

The engine Last Bolt Ceremony was held Wednesday at Pratt & Whitney’s Middletown Engine Center in Connecticut. This engine marks the beginning of an eight-engine validation and certification program. 

“Completion of the first PW1524G engine for testing is an important milestone for the C Series aircraft program,” Benjamin Boehm, vice president, Commercial Aircraft Programs for Bombardier, told Pratt & Whitney employees at the Last Bolt Ceremony on Tuesday.

Pratt & Whitney recently concluded PurePower engine core testing with more than 260 accumulated test hours.  In addition to the core testing, Pratt & Whitney has performed critical module-level testing for the PurePower engine program, including fan drive gear system testing with simulations of more than 60,000 takeoffs and landings, and hundreds of hours of testing on the low and high-pressure compressor with advanced designs meeting or exceeding efficiency and operability goals.

Pratt & Whitney is a world leader in the design, manufacture and service of aircraft engines, space propulsion systems and industrial gas turbines. United Technologies, based in Hartford, Conn., is a diversified company providing high technology products and services to the global aerospace and building industries.
