launching tube (水雷等的)發射管。

launching ways

In order to open the cover of a concentric canister launcher ( ccl ) automatically with the jet during its launching , four schemes are put forward , viz . fracturable cover , eccentrically positioned interior and exterior launching tubes , jet guides of assymmetric construction , and covers made of heterogeneous materials 摘要為實現導彈自力發射時同心發射筒前蓋自動向一側開啟,討論了4種燃氣開蓋方案:易碎蓋方案、內外筒偏心蓋方案、半導流錐方案和各向異性材料發射筒蓋方案,并用數值方法模擬了各種方案的筒內復雜三維流場。

Those above exploitation of technologies created good conditions for our company to develop the important new products such as the super high power launching tubes and the export electronic tubes and so on 上述工藝的開發成功為我公司超大功率廣播發射管和出口的電子管等重點新產品的研制創造了良好的條件。
