Abstract

This work is focused on effect of inplane loading on sound generated by an airplane taking off from a floating runway. Assuming runway as a simple, infinitely long beam, modeled as a Timoshenko-Mindlin plate floating on water, an expression for sound radiation incorporating inplane loading is developed, for a wave number ratio of 0.1 to 2.2, to study effect of varying take off speeds and inplane loading. In developing this expression, a Fourier transformation in space in wave number domain is utilized rather than using wave propagation method to reduce analysis to a substructure.
