Astrium has done considerable work already on the Romeo rocket engine that would power the climb to space, and wind tunnel testing has proven the aerodynamic shape.

Astrium公司已经对Romeo火箭引擎进行了相应的改造工作，以驱动飞船爬升至太空，并且风道测试已经证实了气动外形。公司很快将会开始火箭发动机测试。

The calculated piston wind velocity accords with the measured result on site through making a comparison with tunnel aerodynamic test data of real vehicles.

以实车的隧道空气动力学试验资料为参照进行对比计算，计算活塞风速度与实测结果较好符合。

Therefore, lucubration of tunnel aerodynamic effect's mechanism and corresponding alleviation measure is very necessary.

因而，对于隧道空气动力学效应的作用机制和其减缓措施进行深入研究是非常必要的。
