The quality of steelwork products depends on the geometric precision flat products. Heavy-plate rolling mills produce plates for large-diameter pipes and use in shipbuilding, mechanical engineering, construction. This is why requirements are so stringent. Today’s Mills 5000 up to 5 m width; operation these units shows ‘camber’ defects axial shift roll at stand exit point. induces greater loss m...

The accelerated growth in aircraft industries desire effectual schemes, programs, innovative designs of advanced systems and facilities to accomplish the augmenting need for home-free air transportation. In this paper, a contemporary conceptual design of a cambered airfoil has been proposed in order to providing augmented effective lift force relative to the airplane, and to eliminating drawbac...

To find nontrivial high dimensional integrable models (especially in (3+l)-dimensions) is one of the most important problems in nonlinear physics. A systematic method to find some nontrivial high dimensional integrable models is established by means of noninvertible deformation relations. Starting f rom a noninvertible Miura type transformation, we find that the (l + l)-dimensional sinhGordon m...

Aerodynamic design optimization of an airfoil for the Mars exploration airplane has been demonstrated by using an evolutionary algorithm. The adaptive range genetic algorithm is used for efficient and robust design optimization. Two-dimensional Navier-Stokes solver is used for accurate aerodynamic performance evaluation. The present computation is parallelized on the SX-6 vector computers in In...

This paper presents a distributed parameter optimal control method. The state-space equation of wing bending-torsion aeroelasticity is formulated using aeroelastic differential operators. The optimal control problem is formulated as linear quadratic regulator in a Hilbert inner product space. The solution to the optimal control problem leads to a differential operator Ricatti equation. Using a ...

A robust technique for determining the wing kinematics, body position and attitude of a free-flight dragonfly is described. The new method is based on a projected comb-fringe technique combined with the natural landmarks on a dragonfly, allowing us to establish the local body-centered coordinate system with high accuracy, and to measure the body attitude at any instant. The kinematic parameters...

The objective of this paper is to describe a model for the simulation lateral dynamics vehicle, specifically buses, under variable trajectory conditions, such as camber and radius curvature; in addition, speed added parameter. study prevention vehicle rollover sideslip. An 8 degrees freedom was developed, considering front rear section bus with its respective suspension system, both sections ha...
