A pantograph serves as a vital device for the collection of electricity in trains.However,its aerodynamic resistance can limit the train’s running speed.As installing fairings around the pantograph is known to effect...
At cruising speed,one of the most significant contributing factors to train fuel consumption is aerodynamic drag,and the leading locomotive experiences much more drag than any other car in the train.This work reports ...
In this study,two dimensional unsteady flows of cylinder and cylinder with additional fairing close to a free surface were numerically investigated.The governing momentum equations were solved by using the Semi Implic...

A new method to the problem of fairing planar cubic B-spline curves is introduced in this paper. The method is based on weighted progressive iterative approximation (WPIA for short) and consists of following steps:...
With the testing fairing of LM-5 falling to the recovery airbags on its two sides,the prototype fairing separation test of LM-5 ended smoothly on July 5.The fairing would enter into its final model phase after data an...
