MTU Aero Engines held a “last bolt” ceremony to mark a major milestone in the development of Pratt & Whitney’s PurePower PW1524G geared turbofan engine slated to be used on Bombardier C Series. The company developed the engine’s turbine, which will now be sent to Pratt & Whitney to be installed on the first PurePower PW1524G engine. The engine will then begin testing procedures.
We hear a lot about turbofan engine research, in such things as unducted fans, open-rotor designs and geared turbofans. Where is rotorcraft engine technology headed?
Over the last year, Van Horn Aviation (Booth No. 3409) has introduced new tail-rotor blades for the Bell 206 and 206L models that the company says significantly reduce noise, pedal forces and maintenance requirements and have a higher life limit than OEM blades. The new 206L tail-rotor blades received an FAA STC on February 8.
CFM International continues to work “on a daily basis” with Boeing and Airbus on new engine applications for the 737 and A320 families, according to Eric Bachelet, president and CEO of the General Electric-Snecma joint venture.
Bombardier Learjet 60, Palm Springs, Calif., March 31, 2007–N244X, operated by Jet Solutions, suffered a loss of power in its left engine while cruising at 41,000 feet msl.

The comment period on the FAA’s proposed changes to Part 23 certification regulations governing very light jets (VLJs) has closed, and commenters on the proposal submitted approximately 30 opinions about the notice of proposed rulemaking (NPRM).
While focused on delivering geared turbofan (GTF) engines for the new Mitsubishi MRJ and Bombardier C Series, Pratt & Whitney is turning its attention to the wider applications of a technology that offers a 12- to 15-percent improvement in fuel burn by allowing the engine fan and low-pressure turbine to operate at optimum speeds.
Making its first-ever appearance in the Middle East, the U.S. Air Force F-22 Raptor is flying over each day from Al Dhafra airbase, Abu Dhabi, for its 14-minute display slot. Major Dave “Zeke” Skalicky is showing off America’s top-of-the-line stealth fighter with a serious of gravity-defying maneuvers.
Embraer has selected the Rolls-Royce AE 3007A2 engine to power the Brazilian manufacturer’s new Legacy 650, it was announced here yesterday.
Certification of the 9,200-pound thrust turbofan is expected in late 2010, in time to enter service with the first aircraft before the end of the year.
Dassault Falcon 900B, Gatwick, UK, Jan. 20, 2007–The UK’s Air Accidents Investigation Branch (AAIB) has ruled the probable cause of the uncontained engine failure was the fracturing of a stage-two low-pressure (LP) turbine blade due to a casting defect, with the possibility that this was caused by a third-stage blade failure.
