And an engineering application with DCS in Zhuzhou was analyzed.
Moreover, they concluded that the maximum cooling radius of the DCS in engineering applications should not exceed 960m[5].
And an analysis on the engineering application in Shennongcheng town project was conducted.
The results showed that thermal insulation layer with a thickness of 0.04m is appropriate in engineering applications.

Introduction Unmanned Aircraft (UA) are being used in an increasing number of civil and military applications.
In order to integrate them into civil airspace, reliability has to be ensured for the components used.
Failure Rate Model The Weibull model is one of the most commonly used lifetime distributions in reliability engineering [10].
