A fast Boundary Element Method (BEM) is adopted to study the shielding effects of monopoles on a BWB civil aircraft without freestream flow.The parameter studies of model fidelity of outer mold line, frequency, nacelle, model scaling and engine position on the noise shielding effects of a Blended-Wing-Body aircraft are performed. And the freestream flow effect on noise shielding is under study.
