The drag curve or drag polar is the relationship between the drag on an aircraft and other variables, such as lift, the coefficient of lift, angle-of-attack or speed. It may be described by an equation or displayed as a graph (sometimes called a "polar plot"). [1] Drag may be expressed as actual drag or the coefficient of drag. tata harrier 2022 launch dateWebSep 30, 2015 · Lift The lift curve slope of a flat plate is the same as that of regular airfoils, complete with stall. They have a zero-lift angle of attack of 0° (obviously) and separated flow on the suction side. The maximum lift coefficient of 0.7 to 0.8 is reached at moderate angles of attack - details depend on the aspect ratio. tata harrier airbags

"Webassumes a linear lift-curve slope for the airfoil sections that form the wing. This lift-curve slope is typically close to 2π lper radian. As mentioned before, LLT is based on a linear relationship between section lift and section angle of attack. With this linear assumption, and with the assumption of a straight lifting line, the theory provides " - Effect of aspect ratio on lift curve slope
