Lethbridge Herald, The (Newspaper) - September 27, 1972, Lethbridge, Alberta 46 THE LETHBRIOGE KERAID Wednesday, September 27, 1972 Control of violent jet winds envisioned New York Times Service WASHINGTON Wing tip Uio miniature tor- nadeos tliat trail for long dis- tances behind large aircraft, can tear light planes apart or hurl heavier ones to the ground. Prof. Shao Yuan of George Washington University here pro- poses to control the violent winds by installing little jets along (lie wing ends. Yuan's equipment is protect- ed by Patent issued recently. It Is to undergo wind tunnel tests later tills year, at the National Aeronautics and Space Administration's Langley Research Centre with funds pro- vided by the air force. Heavy air pressure below the wing causes an upward rush at the ends. To offset this turbulent wake, the patent provides for a row of openings along tlie tip through wlu'ch blasts of air or gas are blown in a tangent direction, The gas can lw bled f.-om a jet engine or air can come from a cross-flow blower. The inventor reports that pre- liminary wind tunnel experi- ments on the George Washing- ton campus have proven his sys- tem to work successfully, and that elimination of the vortices causes an increase of about 10 per cent in wing lift. As the in- vention applies also to votary wing craft, the bbde slap hbiso of helicopters is eliminated. Yuan has stu primarily aircraft vortices, but his patent covers application of the prin- ciple under water to ship's pro- peller.
