Abstract

It is common to see clouds in the form of the sky, known as contrails, which are behind the engines of a reaction plan. What is not always visible is a wind whirl that comes out of the top of each wing - like two small horizontal tornadoes - leaving behind a turbulent awakening behind the vehicle. Awakening is a destabilizing flight hazard, especially for smaller aircraft that have the same flight path. Recent research at the University of Illinois has shown that although most of the wings used today create these turbulent vortices, wing geometry can be designed to reduce or eliminate almost the entire comma. In the study, the characteristics of vortex and awakening were calculated for three classical wings: wings and elliptical wings developed in the classical R.T. Jones and Ludwig Prandt. "The configuration of the elliptical wings has been used as the gold standard of aerodynamic efficiency for the best part of a century. We teach our students that they have optimal load characteristics and that they are often used when looking at wings efficiency, for example by minimizing traction, said Phillip Ansell, assistant professor at the Department of Aerospace Engineering at U of I. In a previous experimental study on optimizing wing configurations, Ansell has learned that you can achieve the efficiency of the wing system with a non-elliptical wing profile. Previous academic studies have shown that, in theory, there are other models that actually offer less resistance to a flat wing for a fixed amount of elevator generation. But what is missing is a real apple experiment - something else to prove it. In this new research, Ansell and his graduate student, Prateek Ranjan, used the real data from the previous study to analyze the configurations of the three wings. "We followed this because we saw a certain curiosity in our measurements in the previous experiment." In this new study, we simulated the flow of these three wings and we saw significant differences in how the vortexing and awakening of three Wings Wings Jones and Prandtl did not have peaks like elliptical wings, they had a more gradual deformation of the entire ditch than the immediate consistency of change. Now we know we can delay the formation of structures, the vortex awakens and increases our wishes for distance to pass 12 times, making it weaker and less dangerous for the plane to pass through it. “We look at how wing wings and information can be used to understand how the wind swirl process takes place. This study allows us to be aware of how the wings configuration affects wind formation and wakes up studying the extremes of the wind immediate and delayed, Ansell said. Interestingly, I found that one of the worst offenders creating vortexes is really the distribution.”
