WebDec 14, 2000 · The waves interact causing vibrations as great as 20mm. These vibrations shake the ballast, which can lead to track alignment and sleeper support problems, requiring frequent remedial work. Problems with the bow wave effect have caused speed restrictions to be imposed on high-speed lines at Ledsgard in Sweden and at Stilton Fen near … WebFeb 1, 2016 · In a probe and drogue aerial refueling system, the bow wave of the receiver aircraft will produce a strong aerodynamic effect on the drogue once the receiver follows the drogue at a close distance ... tidb prometheus

WebApr 1, 2016 · The wind effect from the receiver aircraft is generally referred to as the forebody effect 2 or the bow wave effect 7.As shown in Fig. 1, a strong bow wave induced by the forebody of the receiver will change the flow field that the drogue is exposed to, and the forebody flow field tends to push the drogue away when they are close to each other … WebThis paper proposes a lower order dynamic model to describe drogue dynamics under the bow wave effect. The model consists of two components: one is a second-order transfer function matrix to describe the drogue dynamics, and the other is a nonlinear function vector to describe the bow wave effect model. A closed-loop simulation including the ... WebA special type of bow, called a bulbous bow, is often used on large power vessels to reduce wave-making drag.The bulb alters the waves generated by the hull, by changing the pressure distribution ahead of the bow. Because of the nature of its destructive interference with the bow wave, there is a limited range of vessel speeds over which it is effective. tidb parser github
