Effect of inplane loading on sound radiation of a floating runway when an airplane is taking off
Keywords:Moving Load, Timoshenko-Mindlin plate, Floating runway, Inplane loading.
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.
