2024年8月22日 · The chord definition is an example. Normally, chord is the connection between the most forward part of the airfoil nose and the tip of the trailing edge, so your caliper method …

This is why I said that increasing chord will decrease stability. During design, you watch for a size called tail volume. This is the area of the horizontal tail surface, multiplied with it's lever arm …

Since the chord is squared, deeper sections of the wing are overrepresented in the result. The resulting rectangular wing will have a larger area than the original, tapered wing but the same …

2021年4月25日 · a) spanwise is from root to tip, generally following the quarter-chord line, and chordwise is the direction that gives the shortest distance from leading edge to trailing edge, …

If you increase the chord, lift goes up almost linearly and stability decreases, because now the wing's lift force has a longer lever arm in flow direction. By increasing chord, you decrease …

2020年9月29日 · The pictures below (own work) show the circulation over chord produced by camber alone (so AoA is 0°) on the left and the Birnbaum distribution alone on the right (so …

2018年4月19日 · However I would like to know the ideal/optimal chord (actually I would like to know the theory/formulas used) not a range. Imagine this: if I plot a graph of EFFICIENCY x …

2016年10月11日 · Pilots, dispatchers or load masters will calculate the weight and balance with respect to the aircraft datum. Unfortunately, we need to change where the reference point is …

2017年3月6日 · This curve is described by a polynomial function at each point along the chord axis. An airfoil may have a camber line which changes direction at one or more point, and …

2017年5月31日 · It would be a line drawn from the chord where any flow hits the leading edge, to the point where that same flow leaves the trailing edge. The fact that lines called "relative wind …
