4-這是一篇美國的AeroSpace America在2018年針對混合式火箭的報導。
不過可能之前沒有說明得很清楚導致報導內容有點錯誤...(因為小編都PO中文居多啦XD) 我們做推力控制的引擎是使用"雙氧水"混合式推進系統， 之前也有PO在FB過。如下方連結: (https://www.facebook.com/ARRCRocket/videos/1288540024624534/) 。目前正在將其推力放大至120-150 kgf, 而這更是HTTP-3A火箭計畫中不可或缺的一部份, 其設計就是要用來做推力向量控制使用。 未來我們將陸續公開HTTP-3A的計劃內容，請大家盡請期待吧~
A recently reported The 2018 Year In Review of Aerospace America has reported ARRC's research in hybrid rocket propulsion using cheap and simple ball valve for precise throttling of H2O2/plastic hybrid rocket engine.
The report is basically correct, but with a mistake that we are using H2O2, not N2O for this technology.
Our throttlable hybrid rocket engine applies H2O2 and plastic as fuel and oxidizer respectively.
A typical hot-fire video clip can be found at https://www.facebook.com/ARRCRocket/videos/1288540024624534/
And we are currently scaling it up to 120-150 kgf and apply it to the HTTP-3A rocket for the TVC purpose.
More development activities will be released as time goes on.
