,Best wing system: an exact solution of the Prandtl’s problem,were obtained through an approximate procedure. In the present paper we obtain an exact solution of Prandtl’s problem. In particular, we prove that the lift on the horizontal wings results of the superposition of a constant and an elliptical distributions and, on the vertical wings, it is butterfly

Numerical simulation of the dynamics of boats by a variational inequality approach,ynamics of a rowing boat, simulated as a rigid body. We focus on an approach based on formulating the floating body problem as an inequality constraint on the water elevation. A splitting procedure is used to develop an efficient numerical scheme where the inequality constraint is imposed only on a

Concepts of Active Noise Aircraft Cockpits Reduction Employed in High Noise Level,est of researchers. Also, some commercial applications were initiated by leading manufacturers. For this purpose, fundamentally different approaches were used. While active noise compensation reduces the noise level by generating an interfering antinoise, structural vibration control aims to limit s

Best Initial Conditions for the Rendezvous Maneuver,ity of the chaser spacecraft vis-à-vis the target spacecraft. In this research, the initial separation velocity components are assumed free and the initial separation coordinates are subject to only the requirement that the chaser-to-target distance is given. Within this frame, two problems are stud

Variational Approach to the Problem of the Minimum Induced Drag of Wings, theory, based on a variational approach, is proposed in order to revise such a problem and provide one with a support for optimizing more complex wing configurations, which are becoming of interest for future aircraft. The first step of the theory consists in finding a class of functions (lift dist
