Advance drag reduction technique
Advance drag reduction technique
(OP)
Hi everyone,
I'm doing a research on advance drag reduction technique that are being used or have the potential use on aircraft. Would anyone know any useful sites or books about this ?!
Thanks heaps
Andy

RE: Advance drag reduction technique
Burt Rutan's designs are almost an education in drag reduction. The Questair Venture is a totally different approach, reducing wetted area and using long, high aspect ratio wings.
LoPresti makes many items for reducing drag on existing planes.
Fin type vortex generators are commonly used on lightplanes
Air flow is an incredibly complicated area of study where what sounds logical doesn't always work, and theoretically ideal designs using laminar flow or supercritical airfoils may create dangerously unstable designs.

Hope this helps. For good reviews and papers, check out JFM, Physics of Fluids, Annual Review of Fluid Mechanics, Progress in Aerospace Sciences, AIAA Journal and Journal of Aircraft, and the Aeronautical Journal (RAeS). There are also plenty of books out there. You may want to check out the book by Gad-el-Hak and visit his website.

for reduction of induced drag you may want to visit www.winggrid.ch where new non-classical concepts are exposed.
