從數發試驗回收的鋼托的表面燒蝕痕跡,可判斷相近撞擊速度下反應的烈度不盡相同。It is these particles that can change nitriding layer microstructure and that accelerates the layer formation. nitrogen is infiltrated through the surface of metals and it changes the chemical components. as a result, the surface of metal has good performance with high hardness, high resistant attrition, high fatigue strength, high resistant erode and resistant die burn
這些高能粒子可以改變滲層組織,結構和促進化學反應過程,加速滲層形成,使氮元素滲入金屬表面,從而改變金屬表面的化學成分,使之具有高硬度、高耐磨性、高疲勞強度、高腐蝕能力及抗燒傷性。The simulations results show that the spoiler is available to make the fuel and the oxidizer coming from the former to stay in the cavity for a long time, to let the fuel and oxidizer mix and burn completely. since there is a high temperature zone forming by vortex in the middle of the motor, it required a restricted thermal protection. the plate with holes decreased the vortex function in the cavity, which could not promote the combustion efficiency, but to decrease temperature in the cavity and be benefit to thermal protection of the wall
計算結果分析表明:擾流板可以使燃料和氧化劑在擾流腔內的滯留時間加長,促進燃料與氧化劑的摻混燃燒,提高燃燒效率,但由於渦流在發動機的中間部位形成了高溫燃燒區域,致使局部燃料和絕熱層燒蝕速率增大,加大了熱防護的難度;孔板結構減弱了擾流腔內迴流區的漩流作用,不能增加推進劑燃燒效率,但可以使擾流腔內的溫度降低,給壁面熱防護帶來好處。Based on that, the system developed for ablation area measurement combines mechanics, optics and computer organically, according with the development trend of instrument towards high precision > integration and intelligentizing. it has been in work with excellent efficiency
