Aircraft wing aspect ratio calculator software#

From what I have read, it seems Wing Aspect Ratio before Winglet Application has a bearing on the 'after-market' or 'retro-fitted' Winglet. I believe there is more to it that can be directly/mathematically calculated, in theory, before reaching the Wind Tunnel. I appreciate your insight and references, but I feel your answer is too simple. Winglets increase the effective dihedral of swept wings. See the Maughmer artcile cited previously. On sailplanes, winglets can actually improve the roll rate. See the Boeing Aero article cited previously. Winglets on swept wing commercial aircraft do not adversely affect roll response if properly designed.

This is the realm of CFD software and wind tunnel testing. We know of no mathematical process(es) which will accurately answer your specific question. There's a good explanatory article (PDF format) which can be downloaded from the Boeing web site. Toe in or out is determined by how much lifting load is acceptable at the extreme of the wing. Last question, if Winglets reduce Roll Rate, would a reduced Dihedral or even an Anhedral compensate for Winglet negative or less than desired affects?įor AR=b^2/S, the area of the winglets is added to the area of the main wing, and the height of the winglets is added to the span. Suppose an aircraft with a 9 degree Dihedral, a NACA 2412 Wing, 42 feet Span, and approximate 4.8 feet chord, what winglet would be suited, how much would the Aspect Ratio increase, and could you provide the math? Would it be just as efficient to extend the wing to achieve the same Aspect Ratio? If a Wing has a 9 degree Dihedral, then should the Winglet be perpendicular to the Wing, perpendicular to the ground, or bent outward (away from the fuselage), if so how much?Īlso, should the Winglet Airfoil be symmetrical or in the form of the Wing, say a NACA 2412, for example? Looking Top Down at a Wing with Winglets should the Leading Edges be Toed In or Toed Out? If Aspect Ratio is defined as: AR=b²/S or b/c, simply, then how does a Winglet increase Aspect Ratio? Is the Area of each Winglet added to the Area of the Wing or is it applied another way? Any Aeronautical Engineers and Test Pilots:
