Noise characteristics of supersonic passenger planes
Abstract
In the present paper, the noise characteristics of a supersonic transport are studied as a function of the craft's performance and specifications. The results of a parametric analysis of the influence of noise abatement measures on the parameters of the airplane are examined, showing that the noise-optimal cruising parameters differ appreciably from the fuel-optimal parameters. The noise-generating features of an SST and methods of reducing noise are discussed. It is shown that substantial noise abatement can be achieved by increasing the L/D ratio and by using variable-cycle engines.
