The new, 3B1 variant of the General Electric CF34 turbofan, has been launched by Austrian operator, Tyrolean Airways. The Innsbruck-based carrier selected the engine to power four Canadair Regional Jets, the first of which will be delivered in December 1995. The -3B1 has a redesigned first-stage compressor blisk and more efficient high-and low-pressure turbines which give 2% higher climb thrust and a 3% specific-fuel-consumption performance, compared with the CF34-3A1 now used on the aircraft.
