2021年1月15日 · Best lift-drag ratio for most applications, sport airplanes, sailplanes, and semi-aerobatic planes. Symmetrical. Mostly for aerobatic planes, cuts through the air evenly, and generates the same lift in up or down orientation. Great for precision aerobatics. Reflexed. Offers auto stability properties, it’s used mostly on flying wings for that.

2018年12月4日 · Which is best? Let’s break down the main categories to give you a better idea of which airfoil is right for your airplane. Symmetrical . Mostly for aerobatic planes. Cuts through the air evenly. Easy to trim. Great for precision aerobatics. Semi-Symmetrical . For sport planes, semi-aerobatic planes and sailplanes. Excellent lift-drag ratio ...

2014年3月14日 · The most advanced airfoil design in RC planes is in sailplanes built for multiple tasks (thermal climbing/racing). These are airfoils that allow changes to the shape, in flight (such as Martin Hipperle designs). Sailplanes use airfoils with 8-9% thickness, but these are much too thin for powered planes.

2019年1月6日 · All of the popular airfoils for rc planes I have found so far fly most efficiently at high CL compared to others like the NACA 4 digit series, which I don't want because it makes the plane fly slower and make more induced drag.

2016年6月5日 · More than 40 airfoils were tested to choose the best stable airfoil. The main conclusions are: 1. An airfoil is stable if with increase of AoA the CP point moves from the nose to the tail, and the Moment, measured at 1/4 c, is usually increasing with increase of AoA. 2.

2022年10月18日 · Another airfoil choice would be a traditional flat bottom airfoil like you'd see on an old trainer, but add in a few degrees of incidence and you'll have a serious heavy lifting machine. A Clark style airfoil would work well too, but be a bit more efficient than a traditional RC trainer flat bottom airfoil.

2023年11月7日 · In other words, a well build tiny trainer in the hands of a skilled pilot can out preform the best airfoil that is poorly built & flown by a novice. Your choice of airfoil may change the performance by 10-20%, your piloting skill's and build quality can easily exceed that.

2011年5月9日 · I'm thinking of designing my own airplane and was wondering which airfoils are best suited to the speed envelope of the modern pattern planes. I'm looking for the actual airfoil design, not symmetrical, semi-symmetrical, etc...

If the plane is to be a precision aerobat then a symmetrical airfoil is most appropriate because it flies the same in any given attitude. If the plane is to fly slowly or carry a load but is not intended to do aerobatics then a flat-bottom or under-cambered airfoil should be considered.

2020年6月14日 · The correct airfoil depends on what Reybolds number you fly at. For the Reybolds number that most RCscale aircraft fly at, Clark Y and PSU 94-097 are good airfoils. Feel free to browse the airfoils on airfoiltools.com. The airfoils are given as a set of coordinate points which can be imported into your CAD/analysis program of choice
