The temperature distribution on the skin of the stratospheric airship plays an important role in its thermal behavior. In order to analyze the temperature distribution on the skin of the stratospheric airship, a 3-parameter thermal model is investigated. Firstly, a 3-parameter thermal model for the skin is established under the condition that the attitude of the stratospheric airship changes slowly...
An asymptotical trajectory optimization method is proposed to solve the two dimensional trajectory optimization problem on circumstances that the singular perturbation is inapplicable, generally because the time scales of the motion model is not of different order of magnitude. Finding the cause of the coupling between velocity and sideslip angle is the exist of induce drag, the path can be optimized...
