Pratt & Whitney Canada’s PW307B Engine Selected to Power Bombardier’s All-Composite Learjet 85

May 13, 2008 – Bombardier Aerospace has announced its all-composite Learjet 85 aircraft will be powered by Pratt & Whitney Canada (P&WC) PW307B engines. The Learjet manufacturer also announced it selected Innovative Power Solutions (IPS) advanced DC Brushless Starter/Generator (BS/G) System as the engine starter solution for the new midsize jet.

At 6,100 pounds of take-off thrust, the PW307B engine incorporates a suite of advanced technologies, including a TALON(TM) low-emissions combustor, an advanced shock-management fan for increased flow capacity, and powdered-metal, high-pressure turbine disks for improved efficiency. The result is superior performance, better fuel consumption and improved operating economics, together with Pratt & Whitney Canada's trademark dependability. "Our companies have worked together for many years on the Learjet 60 aircraft platform, which features the most fuel efficient engine among current production midsize jets," said David Coleal, vice-president and general manager, Learjet. "Our new alliance builds on this success to offer an aircraft and powerplant solution that will deliver exceptional value for operators, featuring superior performance combined with reduced emission levels and low noise."

Pratt & Whitney Canada's PW307B turbofan engine offers the least environmental impact of any engine in its class with a reduction in nitrous oxide emissions that betters International Civil Aviation Organization standards by over 30 per cent. The PW307B also meets Zurich 5 emission requirements for no landing fee surcharges.

"We are very pleased to join Bombardier as the engine supplier of choice in the Learjet 85 program," said Claude Lachapelle, vice-president, Business Aviation, Pratt & Whitney Canada. "The new-generation PW307 is the perfect engine for the midsize jet market, and we believe the combined strengths of the Learjet 85 and PW307B will result in great value for the customer."

Advanced Brushless Starter/Generator system incorporates cutting edge technology IPS' state-of-the-art 500 Amp, 18KW DC Brushless Starter/Generator Systems will be used on both the Learjet 85 aircraft's PW307B engines and the APU. The system has undergone comprehensive evaluations at P&WC on the PW307B engine, demonstrating superior engine start performance under various environmental and input power conditions.

"Our BS/G System offers superior efficiency and reliability as well as reduced complexity, maintenance requirements and weight; all of which contribute to significantly lower life cycle costs and enhanced operational capabilities," said Eli Liebermann, president, IPS. The IPS BS/G System combines both start and power generation functions, thus eliminating traditional air turbine or other dedicated engine start systems, resulting in significant benefits.
