optimal structural architecture of lambda wing uav

optimized structural architect of an unmanned lambda wing aerial vehicle (ulwav) during conceptual design has proven to be a significant challenge due to its unconventional configuration and no historical data for the structural architect. this paper aims to develop a new approach for structural design layout of new generation unconventional aircraft especially for ulwav. the first step in this approach is to investigate the affecting parameters on structural architecture of these aircrafts then using of modal analysis to identification the behavior of these unconventional geometries for a general methodology development. the result of this modal analysis is apportion aircraft geometry to conventional substructures with already well-established defined architect. ulwav structure architecture has been done by combining the structural architecture of sub-sections and with respect to requirements for systems installation, stealth design objective and packaging requirements. here the catia software is used to optimize general architect with parametric model. to validate the results, the maximum static stress and maximum displacement of the structure were calculated using msc / patran software and compared with the values obtained from the optimization process. dynamic analysis and buckling stability of structural composite shells are also controlled below. the architect methodology was applied to a case study of an ulwav. the weight of the optimized structure has also been confirmed by typical case study researches.
