- Summary:
- The difficulties experienced in properly holding thin tipped or tapered aerofoils while testing on an N.P.L. type aerodynamic balance even at low air speeds, and the impossibility of holding even solid metal models, at the high speeds attainable with the National Advisory Committee's wind tunnel, necessitated the design of a balance which would hold model aerofoils of any thickness and at speeds up to 150 m.p.h. In addition to mechanical strength and rigidity it was highly desirable that the balance readings should require a minimum amount of correction and mathematical manipulation in order to obtain the lift and drag coefficients and the center of pressure.
