| Abstract: | Based on the formula for calculating random errors ofwind tunnel Testing data, which have been giyen in lecture one, thecomposition and infuence factors of the errors in wind tunnel flow parameters, aerodynamic pressure coefficients, force and moment coefficientswcre analysed. The variation law of the errors in these parameters andcoefficients were also indicated |
