Wing Structural Weight Approximations
The paper explores the effect of numerical noise and uncertainties on response surface approximations for wing bending material weight for a high speed civil transport (HSCT) design. The accuracy of the response surface approximations is improved by identification and repair of outliers present in the data due to noisy structural optimization. The use of correction response surface approximatio...
متن کاملDesign and Analysis of Aircraft Wing
In the present study, a general aviation airplane is designed and analyzed. The design process starts with a sketch of how the airplane is envisioned. Weight is estimated based on the sketch and a chosen design mission profile. A more refined method is conducted based on calculated performance parameters to achieve a more accurate weight estimate which is used to acquire the external geometry o...
متن کاملConceptual Design of Conventional and Oblique Wing Configurations for Small Supersonic Aircraft
A design process that included high and low fidelity modeling integrated through Kriging-based fits of the high fidelity results was developed and demonstrated on conventional and oblique wing designs. Additional design variables are required when higher fidelity models are introduced, and rather than sub-optimize the design (for example using additional design variables to minimize drag), the ...
متن کاملISOGEOMETRIC TOPOLOGY OPTIMIZATION OF STRUCTURES CONSIDERING WEIGHT MINIMIZATION AND LOCAL STRESS CONSTRAINTS
The Isogeometric Analysis (IA) is utilized for structural topology optimization considering minimization of weight and local stress constraints. For this purpose, material density of the structure is assumed as a continuous function throughout the design domain and approximated using the Non-Uniform Rational B-Spline (NURBS) basis functions. Control points of the density surface are...
متن کاملParametric wing profile description for conceptual design
Introduction A fundamental part of aircraft design involves the wing airfoil optimization, establishing an outer shape of the wing which has good aerodynamic performance, good internal volume distribution for fuel and systems and which also serves as an efficient structural member supporting the weight of the aircraft. As for all optimization tasks, the complexity of the problem is directly cou...
