چکیده
A parallel numerical optimization method for the airplane wing design has been established The extension of traditional Evolution Strategies by new and alterna tive methods combined with a load management for parallel processes leads to the MEPO optimization system The concept of the system allows bene cial usage of parallel processing features for running the optimization algorithms as well as the application speci c simulation codes In this way unacceptable turn around times in the design process of airplane wings can be reduced signi cantly The low amount of communications between computer processor units makes it possible to employ workstation clusters e ciently Coupled with simulation codes of DASA and DLR a powerful program system for optimizing airplane wing designs has been created Highly promising results in the calculation of wing shapes for the future Airbus A XX now lead to a commercially usable program

On the Design of Nonlinear Discrete-Time Adaptive Controller for damaged Airplane
airplane in presence of asymmetric left-wing damaged. Variations of the aerodynamic parameters, mass and moments of inertia, and the center of gravity due to damage are all considered in the nonlinear mathematical modeling. The proposed discrete-time nonlinear MRAC algorithm applies the recursive least square (RLS) algorithm as a parameter estimator as well as the error between the real ...
متن کاملFatigue Life Assessment of Composite Airplane Wing Subjected to Variable Mechanical and Thermal Loads
The purpose of this paper is to estimate the fatigue life of an airplane wing with laminated composite skin, subjected to variable mechanical and thermal loads. To achieve this aim,at first, the three-dimensional model of airplane wing was drawn in CATIA software. Then, by transferring the model to the ABAQUS software, the finite element model of the wing wascreated. H...
متن کاملGenerating Airplane Wings for Numerical Simulation and Manufacturing
We describe an algorithm for automated generation of multi-parted airplane wings from a cross-section given by a point cloud and the top view of the wing. The relative thickness of the wing (thickness/chord) can be varied from section to section. A rounded tip with two design parameters and GC1-continuity at the crossing to the wing is automatically computed. Constrained approximation and fairi...

In the present paper we give account of an effort that aimed at the unification of the whole geometric preprocessing that preceded the wind tunnel readings with a realistic airplane wing model in a recent research project. This preprocessing includes the automated generation of the CAD models which were used for the manufacturing of the multi-parted wing-fuselage configuration and the generatio...
