Abstract:

This book contains an investigation of two interrelated problems finding optimal material distribution in the wing structure and selecting the structural-technological solutions. The optimal law of material distribution is found by the methods of nonlinear programming. On the basis of replacing a variable function by a set of discrete parameters, the calculational relations criterial functions, conditions, restrictions corresponding to the numerical and analytical methods of solving the design problem and various calculational schemes for the wing are obtained. First, the simplest cases are presented - single load system, absence of heating, isotropic structure, etc. On the basis of these cases, general relations are derived permitting consideration of the effect of aerodynamic heating, the load spectrum, and pliability of the wing fastening. The transition from the calculational scheme to the structural scheme and selection of the optimal structural-technological version of the wing are carried out on the basis of analyzing the additional weight, sources of which are the stability of the structural elements, reliability, technological factors and operating conditions.
