NASA - National Aeronautics and Space AdministrationCleveland, OH – Car, truck, train and aircraft manufacturers have made great strides in recent years to reduce fuel consumption, resulting in consumer savings and lower emissions. With NASA’s help, the aircraft industry is striving to increase fuel efficiency even more.

One way to do that is to create new aircraft engine designs. Engineers at NASA’s Glenn Research Center in Cleveland are testing a new fan and inlet design, commonly called a propulsor, which could increase fuel efficiency by four to eight percent more than the advanced engine designs airlines are beginning to use.

NASA Dryden Flight Research Center

NASA - National Aeronautics and Space AdministrationEdwards, CA – Aeronautics researchers at NASA’s Dryden Flight Research Center recently completed flight tests of a unique experimental jet engine inlet design in the Channeled Center-body Inlet Experiment, or CCIE.

The experimental inlet was checked out on NASA Dryden’s F-15B aeronautics research test bed aircraft, which continues to be an innovative and cost-effective tool for flight test of advanced propulsion concepts.

NASA Dryden’s F-15B research testbed aircraft flew the CCIE experimental jet engine inlet to speeds up to Mach 1.74, or about 1.7 times the speed of sound. (NASA / Jim Ross)
