中文摘要 | 本文是以同時求解一組二維軸對稱圓柱座標的質量、動量、能量守恆方程式之數 值模擬方法,模擬氣體傳動式自動武器中的活塞運動情形及氣流場狀況,並探討洩氣孔在氣 筒中不同位置時對整個氣筒流場、壓力、活塞運動的影響及與射擊速率的關係,藉以瞭解洩 氣孔位置對氣動傳動式自動步槍之影響。 結果顯示活塞往復一次所需的時間隨洩氣孔位置由前至後而增加。而洩氣孔位置在較前方時 活塞運動到底衝擊速度較低,反之則較劇,同樣的,在洩氣孔位置較前方時射擊速率較高, 在後方時射擊速率較低。 |
英文摘要 | Gas operated automatic weapons are those weapons that have a gas driven mechanism to operate the bolt and its associated moving components. A portion of the propellant gas passed is drawn to activate a mechanism to retract the bolt. Given pressure versus time and velocity versus time curves at gas port, the velocity of recoil at the end of the gas piston stroke can be calculated by solving the mass, momentum, and energy conservation equations in gas cylinder. The fire rate can be controlled by adjusting the exhaust area and the location of exhaust in gas cylinder. The purpose of the paper is to find different fire rate by regulating the location of exhaust along the gas cylinder. Piston's motion is also described in this paper. |
