A nonlinear model consisting “yaw, roll, longitudinal, lateral and pitch” has been developed in which, tire and suspension characteristics have been considered. Tire model is based on the elliptic concept and tire Calspan data. According to this tire model, cornering force and aligning moment are computed as a function of slip and camber (inclination) angles, normal load, tire adhesion characte...

MOTIVATION A number of inconsistencies in genome annotations are documented among bacterial strains. Visualization of the differences may help biologists to make correct decisions in spurious cases. RESULTS We have developed a visualization tool, CAMBerVis, to support comparative analysis of multiple bacterial strains. The software manages simultaneous visualization of multiple bacterial geno...

This paper presents an adaptive control approach for flutter suppression of a performance adaptive aeroelastic wing equipped with a variable camber continuous trailing edge flap design. The adaptive control approach is based on the optimal control modification method augmented to a linear quadratic gaussian optimal control design. A model reduction based on a singular perturbation approach is p...

Leading-edge vortices that form at offdesign conditions can profoundly influence the aerodynamic characteristics of highly swept slender wings. predict wing geometry effects on the progressive spanwise development of leading-edge vortices is presented. This method, which can account for sweep, camber, twist, airfoil shape, flap deflections, and planform shape, is shown to be a useful tool for a...

A new optimization approach for robust design, design for multi-objective six sigma (DFMOSS) has been developed and applied to robust aerodynamic airfoil design for Mars exploratory airplane. The present robust aerodynamic airfoil design optimization using DFMOSS successfully showed the trade-off information between maximization and robustness improvement in aerodynamic performance by a single ...

Abstract―This paper illustrates the theory behind computational fluid dynamics (CFD) of flow though a gas turbine engine low pressure compressor. The goal of study is to develop a tool to perform shape optimization of low speed airfoils. Mathematical model and computational tool are developed using programming software. Analytical solution is developed to create airfoil geometry. The NACA 4 dig...

During the hypersonics activities of the 1960s, thin shock-layer theory was developed as a rst-order correction to Newtonian theory, in the hope of gaining insight into eÆcient lift at very high speeds. The wings are limited to conical geometry, but can have arbitrary transverse camber. Good predictions were made of the forces generated by delta and caret wings, but no optimization studies were...
