The shipboard effect of helicopter has adverse effect on the flight safety.

In this paper,we simulated the dynamic jet flow field formed by the shipborne solid rocket motor jetting on the shielding board,based on the 3-D thin-layer approximation N-S equations,using Finite Differential Method and also selected observation points to simulate the flow field parameters of immobility point.

The assessment of surface warship combat effectiveness under complicated electromagnetic environment(CEE) is of great importance for the use of surface warship in sea battlefield with information,up to now the study is still on theory.

Both the interfacial effect of solid-liquid and gas-liquidcan influence the heat transfer characteristic.

In this paper, six wollastonite fillers with different kinds of surfaces characteristics were designed to modify properties of polypropylene and the effects on the mechanics performance, interfacial effect and crystallizing behavior of composite material were studied.
