As a designer our task is to generate fuselage through conic lofting method. If an intermediate C/S shape is elliptic then, what should be the appropriate value of conic shape parameter? Correct Answer 0.4142-0.5
Given, intermediate cross section = elliptic. Conic shape parameter CSP = DS / DC, where D = midpoint of line drawn from end point A to end point B, C = tangent point, S = shoulder point. When CSP = 0.4142 and AC = BC then it will generate circular shape. Now, when CSP = 0.5 it will produce parabola. Hence, to generate elliptic cross section value of CSP should be between 0.4142 and 0.5 based on our requirement.
