The introduction of the Bombardier CSeries in 2014 will bring the first application of the next generation of engines for narrow-body aircraft, the Pratt & Whitney PurePower 1000G geared turbofan.  The combination of a new engine and an advanced high technology airframe will generate a very substantial change in the environmental impact of airplanes, the largest we’ve seen since the first generation noisy cigar tube engines were replaced by high bypass engines in the 1980s.  Continue reading
