Pratt & Whitney is celebrating 100 years of aircraft engine innovations while marching full-speed ahead to the next generation of more efficient and sustainable propulsion technologies. 

According to Michael Winter, the chief scientist at Pratt & Whitney parent company RTX, changes in engine architecture over the past 100 years have led to several step-changes in capabilities. For example, the invention of the air-cooled radial engine in the 1920s improved the thrust-to-weight ratio by a factor of 2.5 compared with earlier piston engines.
