Abstract
It is well known that the Busemann biplane can completely cancel the shock waves propagating to the farfield, in two dimensional linear theory with no lift. A new concept of a boomless supersonic transport, which aims for a complete cancellation of the sonic boom of a supersonic transport by applying this theory, is proposed. As a first step, thee performance of Busemann biplane is evaluated, beyond 2D(two dimensional) linear theory. Effects of the nonlinear terms are investigated using 2D Euler simulations. Optimization is carried out to investigate how close the nonlinear analysis results compare to results from linear analysis.
