Parameterized Modeling of Blended Wing Body Aircraft Based on Multi-Scale CST Method [PDF]
In the parameterized modeling of blended wing body aircraft, the commonly used CST method has weak local deformation control capability, while the Non-Uniform Rational B-Splines(NURBS)method has the problem of too many global parameters.

Evolutionary Design via Indirect Encoding of Non-Uniform Rational Basis Splines
A novel approach to produce 2D designs by adapting the HyperNEAT algorithm to evolve non-uniform rational basis splines (NURBS) is presented. This representation is proposed as an alternative to previous pixel-based approaches primarily motivated by ...

Ruling Based Design Method of Curved Origami
ABSTRACT Curved origami attracts the attention of designers in recent years for the potential in the field of building structures for free form curved design. For practical use, the design methods are required to link the mathematically obtained curved surface and the requirements of architectural functions.

Objective This study explores the application of Eurasian eagle‐owl wing characteristics to the design of folding wings for flying cars. By analyzing the aerodynamics of the eagle‐owl wing, we aim to innovate folding wing configurations to improve lift, reduce drag, enhance flight stability, and ultimately increase the overall energy efficiency and ...

One dimensional non-uniform rational B-splines for animation control
Most 3D animation packages use graphical representations called motion graphs to represent the variation in time of the motion parameters. Many use two-dimensional B-splines as animation curves because of their power to represent free-form curves.

Aerodynamic performance analysis of a little penguin wing and penguin‐inspired wing is numerically conducted at a chord‐based Reynolds number Re = 105 to assess its feasibility for use in microair vehicles (MAVs). The results strongly suggest that penguin‐inspired wing shape performs in a superior manner at higher angles of attack (AOAs) in comparison ...

Constant‐Ratio Blended Models of Curves and Surfaces in Euclidean 3‐Space
We consider a simple blending method for parametric curves and surfaces. The described blending method offers a systematic approach to creating smooth transitions between parametric curves and surfaces while maintaining Cn‐continuity. It utilizes the parametrizations of the original objects to achieve predictable variations in shape and enables the ...

CONIC SECTIONS - AN INTRODUCTION TO THE RATIONAL SPLINES
The rational splines have been included in the IGES (International Graphics Exchange Specification) standard for about ten years, but they have been subjects of interest since 1967 [1].
