Meggitt (Stand A536) is introducing a number of products, including new developments in engine monitoring equipment revealed by its Vibro-Meter subsidiary. Fitted on the Boeing 737, for example, the new vibration monitors continuously check specific engine bearings and detect unusual signatures using advanced signal processing.
For the last few years, much of the buzz in the turbine engine world has focused on the new small powerplants from Pratt & Whitney Canada, Williams and the Honda-GE Engines joint venture to propel the emerging class of very light jets. Now the spotlight has shifted somewhat, to advanced technology aimed at developing state-of-the-art engines in the 10,000-pound-thrust class for a new breed of large business jet.
Honeywell’s turbine engine folks are poised for show and tell about something new from something old–the time-tested TFE731 turbofan family–and something a lot newer: advanced technology aimed at developing a state-of-the-art engine in the 10,000-pound-thrust class.
With fuel prices at noticeably higher levels and Stage 4 noise requirements proposed to take effect next January 1, industry and government are working furiously on ways to make turbine engines even more efficient, while further reducing emissions and noise output. NASA is leading the charge, with plenty of help from the engine manufacturers themselves.
Bell says its new anti-torque system will offer directional control, reductions in main rotor speed and noise and higher cruise speeds–up to 170 knots. Bell will evaluate the Propulsive Anti-Torque System (PATS) next year using a full-size gas turbine engine, inlet fan, bifurcated ducting and a series of test thrusters.
