NASA Runs First-Ever Test of New Jet Engine Tech

Dec 13,2018

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.


On today¡¯s jet aircraft, the engines are typically located away from the aircraft¡¯s body to avoid ingesting the layer of slower flowing air that develops along the aircraft¡¯s surfaces, called boundary layer. Aerospace engineers believe they can reduce fuel burn by embedding an aircraft¡¯s engines into these surfaces and ingesting the boundary layer air flow to propel the aircraft through its mission.


It sounds like a simple design change, but it¡¯s actually quite challenging. Boundary layer air flow is highly distorted, and that distortion affects the way the fan performs and operates. These new designs require a stronger fan.


To address these challenges, NASA Glenn is testing a new propulsor in its 8¡¯ x 6¡¯  Wind Tunnel. Designed by United Technologies Research Center with research conducted by Virginia Polytechnic and State University, the rugged boundary layer ingesting (BLI) inlet-fan combination is the first of its kind ever to be tested.


Commercial Aero Engine Shanghai International Forum, based on China National Special Project of Aero Engine & Gas Turbine, is located in Shanghai, China. This forum aims to support aero engine industry development through information exchanges and business cooperation. Initiated by Shanghai Society of Aeronautics and AECC Commercial Aircraft Engine Co., Ltd., this annual forum has been successfully held in the past three years. The Commercial Aero Engine Shanghai International Forum 2019 will be held in the city of Shanghai, at Jeurong Hotel, on March 20th - 21st, 2019.


The forum will analyze optimized solutions that could accelerate the establishment and improvements of aero engine fundamental technology support, R&D and production, modification and verification, product configuration through keynote speech, panel discussions, exhibitions, business meetings and media interviews. Commercial Aero Engine Shanghai International Forum 2019, as an authoritative and timely platform, promises to unite more than 200 distinguished delegates from government bureau, aero engine designer, manufacturer, tester, components providers and software companies.We look forward to meeting you in Shanghai.
