چکیده
|
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. © 2013 aname publication. all rights reserved.
