Abstract:

In response to the need of overall design of a Kliper class vehicle, the cross section of a specific configuration is divided into three shape control function. Based on the splicing conic concept, those functions are closed as a uniform cross sectional shape function, and a cluster of continuous shape cross sections is obtained by dynamically adjusting the small number of control parameters of the shape function. The hypersonic aerodynamic characteristics of the Kliper vehicle is calculated by using engineering method based on the triangular face element, and the resulting data is fitted into a fourth order polynomial, thus reducing one interpolation dimension. Reentry simulation of the Kliper and the Apollo is performed in the same long range task scenario by use of a numerical prediction\|correction reentry guidance algorithm. The reentry trajectory characteristics metrics of Kliper are significantly better than traditional vehicles.
