WebAccording to Europe’s vision for aviation , technological breakthroughs are necessary to accomplish a major step towards the environmental goals of a 75% reduction in CO 2 emissions per passenger/kilometre, a 90% cut in NOx emissions, a 65% reduction of perceived aircraft noise levels (all percentages referred to the transport aircraft ... WebThe trailing-edge wing flaps aim to improve aircraft aerodynamic efficiency and reduce takeoff and landing noise. Fiber optic sensors, previously employed to sense environmental characteristics like temperature and pressure, now provide an important understanding of an advanced aircraft’s structural shape.
Flap Side-Edge Noise Prediction Within Conceptual Aircraft Design
WebNov 19, 2024 · The most promising tip treatment tested was the trailing edge (TE) notch at a radial location of 0.95 r /R with a double slot width and a double depth (DSDD). The … WebApr 7, 2024 · The flap side-edge is a vital contributor to airframe noise. In this study, we propose a novel flap side-edge noise reduction method based on the concept of active blowing air. A long slot is opened from the flap’s lower surface to the tip surface to induce a secondary jet flow, which is driven by the local pressure difference between the … joe taylors catering
