A development of longitudinal static stability analysis method of a Wing-In-Ground effect vehicle in cruise during the design process

The height static stability of a wing can be a main concern for conceptual design of wing-in-ground effect (WIG) crafts. In this research, the stability of a rectangular and compound wing was computationally predicted in ground effect. A realizable k-ε turbulent model was used for simulation the flow filed over the wing surfaces. First, the drag coefficient and lift to drag ratio of numerical simulation were validated by experimental data of the rectangular wing. Next, the stability of the compound wing respect to different ground clearances will be determined and compared with rectangular wing. This study illustrated a deep understanding of static stability of present compound wing in ground effect, which eventually can be a guideline for researchers and designers of WIG craft.

In recent years, with the growth of the power grid power load, the power system voltage static stability problems gradually appear,The study found that, often from the system voltage stability the weakest node set off, and gradually into the surrounding weak (nodes) regional spread. How to determine the system key nodes and area is PSASP voltage static stability analysis method, from the essence of voltage stability and principle, to calculate the power of each node Leading voltage instability mode participation factors to determine the size of voltage stability judgment the weakest node or area.

Solid Edge

A static-stability calculation method for ships which use the second-development of Solid Edge is presented in this paper. The second-development of Solid Edge applied Visual Basic to divide the waterplane and measure the parameters concerned static-stability calculation such as the volume and center of the underwater model. Furturemore, it makes the statics-stability calculation be convenient that the paragraph of static-stability is calculated on the parameters and the dismiss angle is returned. According to the comparison of the experiments and the theory, including different forms of superstructure models, it can be proved that this method is reliable and effective in the static-stability calculation for ships.
