The result of computer and analysis based on blade elements theory shows us that we can regulate the rotate speed of wind turbine rotor by changing set angle and pitch h . variable - pitch system is the key component of the whole wind turbine , which can assure safely pitch - control and brake 本文利用葉素理論,經(jīng)計算分析得出:通過改變風(fēng)力機安裝角可以改變槳距h ,從而改變風(fēng)力機的轉(zhuǎn)速。變距機構(gòu)是變槳距控制型風(fēng)電機組實現(xiàn)變距控制和安全剎車的關(guān)鍵機構(gòu)之一,它的運動由平動和轉(zhuǎn)動兩部分組成。
Powdery propellant , oxide , polymer and agent can be mixed to make slurry explosive , the sensitivity of slurry explosive is discussed ; slurry explosive can be made into special shape destructor , it results of the area , height and setting angle of explosive is related to the destr ucted effect ; the destroying effect of slurry explosive is also studied from the experiment in the air and on the steel plate 在粉碎后的發(fā)射藥顆粒中加入氧化劑、膠凝物及交聯(lián)劑等能制成漿狀炸藥,研究了影響其感度的因素;根據(jù)漿狀炸藥的特點可以用來制造一些特殊形狀的爆破具并其進行了對比實驗;對漿狀炸藥在空氣中和鋼板上的破壞作用也進行了對比實驗研究。
