Experiments Of Propeller-Induced Flow Effects On A Low-Reynolds-Number Wing, Gavin K. Ananda, Robert Deters, Michael S. Selig
Experiments Of Propeller-Induced Flow Effects On A Low-Reynolds-Number Wing, Gavin K. Ananda, Robert Deters, Michael S. Selig
Publications
Novel findings are discussed in this paper that will be especially beneficial to designers and modelers of small-scale unmanned air vehicles and high-altitude long-endurance vehicles that both operate at low Reynolds numbers (Re = 50,000-300,000). Propeller-induced Oow effects in both tractor and pusher configurations on a recta ngular wing using the Wortmann FX 63-137 airfoil (a common low-Reynolds-number high-lift airfoil) are presented in this paper . Significant performance benefits can be found for a wing in the tractor configuration. Experiments, including trip tests and upper-surface oil Dow visualization, show and verify that the propeller slipstream induces early transition to turbulent …
Aerodynamic Analysis Of Low Speed Wing Design Using Taguchi L9 Orthogonal Array, Kenneth Witcher, Ian Mcandrew, Elena Vishnevskaya
Aerodynamic Analysis Of Low Speed Wing Design Using Taguchi L9 Orthogonal Array, Kenneth Witcher, Ian Mcandrew, Elena Vishnevskaya
Publications
The study of aerodynamics has been preoccupied with understanding flight at increasing speeds and ultimately supersonic. Today, this pursuit has advanced the science for both Hypersonic and Transonic flight to near Mach 1 supporting economical commercial flight operations. This research presents the data from a Taguchi array on low speed with twin wing designs to establish the design parameters for their use in low speed and high altitude. Also presented is how aerodynamic advantages can be achieved through understanding the interactions of parameters and their use. This is compared to operational effectiveness when applied to remotely piloted aircraft that are …

Preparing students to be successful in STEM careers is important to foster continued growth in the US and the world. The Real World Design Challenge is a high school design competition focused on the area of aviation. Students work in teams to solve a real world problem using professional tools. The 2018 challenge marks the tenth anniversary of this program. The first students to compete in this competition are now in the work force. This paper describes the background of RWDC, the different challenges that have been used throughout its ten years, the current precision agriculture challenges using UAS, and …
