Final phase – flight testing — of a multi-blade propfan, under development in a 3-year U.S. programme, is expected later this year. Shown is the prototype undergoing static tests in Southern California last year. The goal is to produce a more fuel-efficient propulsion system for commercial aircraft. The programme, called Propfan Test Assessment (PTA), is directed by the U.S. National Aeronautics and Space Administration.
