The initialthrust is provided by the nine-engine cluster, fuelled by kerosene and liquid oxygen.
初始推进力由一拥有九个引擎的引擎组提供,使用煤油和液氧作为燃料。

Using the optimal control theory an optimal control law of agile turn is proposed enabling to eliminate velocity component in vertical director of initial sight under thrust vector control.
For high in situ stress occurred in Ertan dam area, combined action of initial in situ stress field, time and space effect during excavation and external loads arch thrust etc.
