Honeywell Development of 10,000 Pound Engine on Track


Next Generation Turbofan Including Multiple Green Technologies

Engine Will Build on Demonstrated Reliability of the Successful HTF7000

NBAA, ATLANTA.- Honeywell (NYSE: HON) announced today that it is on track with its development of the HTF10000. The HTF10000 is a high-bypass turbofan propulsion system targeted for the next generation of large business jets, with the first run of the HTF10000 core engine scheduled to occur in 2008. Four over-arching tenants are guiding the design and development of the HTF10000 propulsion system: reduced cost of ownership, environmentally friendly design with reduced emissions and lower noise signature, built-in and demonstrated mature engine durability and reliability from initial production, all brought together by an early demonstration phase designed to enable a seamless entry into service.

The HTF10000 incorporates various technologies, materials and design features that enable an increase in operating pressure, temperature and speed levels targeted to further improve fuel efficiency and power to weight ratio while delivering class-leading durability and reliability.

Reduced noise signature is being driven by the forward swept fan design, which is based on a recently completed joint Honeywell-NASA program. Reductions in smoke and emissions with improvements in durability are the focus of Honeywell’s SABRE technology program which features a reduced volume Rich-Quench-Lean (RQL) combustion system.

The HTF10000 is designed to be a true “on condition” engine, with Line Replaceable Units (LRUs) that can be serviced quickly with tools common in every toolbox. The Honeywell maturity path for the HTF10000 is patterned after the highly successful market introduction of the HTF7000 in 2003 which has achieved a dispatch reliability rate of 99.95% well before achieving 250,000 hours of field experience. Adopting the same HTF7000 approach and philosophy into the HTF10000 design along with scale and technology infusion will retain the 15,000 cycle rotor lives and the inherent reliability necessary for 10,000 hours on wing for the new HTF10000 assuring the lowest real and predictable costs of operation in this thrust range as part of our industry leading MSP coverage program.

The HTF10000 design is progressing with orders for castings of blades and vanes already placed with selected suppliers. The TECH7000 is being used as an early test vehicle and work-horse to ready technologies, supporting a HTF10000 demonstration run by late next year. Early validation of critical technologies such as the forward swept fan, and reduced emissions combustion system is already underway on the TECH7000 demonstrator engine. The reduced emissions combustion system has been ‘flown’ on Honeywell’s Boeing 720 flying test bed. The design of the HTF10000 is guided by an “Advisory Board” composed of industry experts with participation from operators, including fractionals, service centers and pilots. The HTF10000 program is built around an early technology validation approach designed to reduce certification risk and deliver a well proven and thoroughly exercised design into the field.
