低腔壓高濃度過氧化氫混合式火箭引擎之研究

為了解決Nitrogen oxide的問題,作者林育宏 這樣論述:

本論文為混合式火箭系統入軌段火箭引擎的前期研究,除了高引擎效率的要求外,更需要精準的推力控制與降低入軌段火箭的結構重量比,以增加入軌精度與酬載能力。混合式火箭引擎具相對安全、綠色環保、可推力控制、管路簡單、低成本等優點,並且可以輕易地達到引擎深度節流推力控制,對於僅能單次使用、需要精準進入軌道的入軌段火箭推進系統有相當大的應用潛力。其最大的優點是燃料在常溫下為固態、易保存且安全,即使燃燒室或儲存槽受損,固態的燃料也不會因此產生劇烈的燃燒而導致爆炸。雖然混合式推進系統有不少優於固態及液態推進系統的特性,相較事先預混燃料與氧化劑的固態推進系統及可精準控制氧燃比而達到高度燃燒效率的液態推進系統,混

合式推進系統有擴散焰邊界層燃燒特性,此因素導致混合式推進系統的燃料燃燒速率普遍偏低,使得設計大推力引擎設計時需要長度較長的燃燒室來提供足夠的燃料燃燒表面積,也導致得更高長徑比的火箭設計。針對此問題,本論文利用渦漩注入氧化劑的方式,增加了氧化劑在引擎內部的滯留時間,並藉由渦旋流場提升氧化劑與燃料的混合效率以及燃料耗蝕率;同時降低引擎燃燒室工作壓力以研究其推進效能,並與較高工作壓力進行比較。本論文使用氮氣加壓供流系統驅動90%高濃度過氧化氫 (high-test peroxide) 進入觸媒床,並使用三氧化二鋁 (Al2O3) 為載體的三氧化二錳 (Mn2O3) 觸媒進行催化分解,隨後以渦漩注入的

方式注入燃燒腔,並與燃料聚丙烯(polypropylene, PP)進行燃燒,最後經由石墨鐘形噴嘴 (bell-shaped nozzle) 噴出燃燒腔後產生推力。實驗部分首先透過深度節流測試先針對原版腔壓40 barA引擎在低腔壓下的氧燃比 (O/F ratio)、特徵速度 (C*)、比衝值 (Isp) 等引擎性能進行研究,提供後續設計20 barA低腔壓引擎的依據,並整理出觸媒床等壓損以及燃燒室等流速的引擎設計轉換模型;同時使用CFD模擬驗證渦漩注射器於氧化劑全流量下 (425 g/s) 的壓損與等壓損轉換模型預測的數值接近 (~1.3 bar)。由腔壓20 barA 引擎的8秒hot-f

ire實驗結果顯示,由於推力係數 (CF) 在低腔壓引擎的理論值 (~1.4) 相較於腔壓40 barA引擎的推力係數理論值 (~1.5) 較低,因此腔壓20 barA引擎的海平面Isp相較於腔壓40 barA引擎的Isp 低了約13 s,但是兩組引擎具有相近的Isp效率 (~94%),且長時間的24秒hot-fire測試顯示Isp效率會因長時間燃燒而提升至97%。此外,氧化劑流量皆線性正比於推力與腔壓,判定係數 (R2) 也高於99%,實現混合式火箭引擎推力控制的優異性能。透過燃料耗蝕率與氧通量之關係式可知,低腔壓引擎在相同氧化劑通量下 (100 kg/m2s) 較腔壓40 barA引擎降低

了約15%的燃料耗蝕率,因此引擎的燃料耗蝕率會受到腔體壓力轉換的影響而變動,本論文也針對此現象歸納出一校正方法以預測不同腔壓下的燃料耗蝕率,此校正後的關係式可提供未來不同腔壓引擎燃料長度設計上的準則。最後將雙氧水貯存瓶的上游氮氣加壓壓力從約58 barA降低至38 barA並進行8秒hot-fire測試,結果顯示仍能得到與過往測試相當接近的Isp效率 (~94%),而此特性除了能讓雙氧水及氮氣貯存瓶擁有輕量化設計的可能性,搭配具流量控制的控制閥也有利於未來箭體朝向blowdown type型式的設計,因此雙氧水加壓桶槽上的氮氣調壓閥 (N2 pressure regulator valve)

將可省去,得以降低供流系統的重量,並增加箭體的酬載能力,對於未來箭體輕量化將是一大優勢。

二維材料於邏輯元件與記憶體內運算應用

為了解決Nitrogen oxide的問題,作者鍾昀晏 這樣論述:

半導體產業在過去半個世紀不斷地發展,塊材材料逐漸面臨電晶體微縮的物理極限,因此我們開始尋找替代方案。由於二維材料天生的原子級材料厚度與其可抑制短通道效應能力,被視為半導體產業極具未來發展性材料。此篇論文為研究二維材料二硫化鉬的N型通道元件之製作技術與其材料的特性與應用。首先,我們使用二階段硫化製程所製備的二硫化鉬沉積高介電材料並使用X-射線能譜儀(XPS)與光致發光譜(PL)進行分析,量測二硫化鉬與四種高介電材料的能帶對準,參考以往製程經驗,可結論二氧化鉿是有潛力介電層材料在二硫化鉬上,並作為我們後續元件的主要閘極介電層。接著使用二階段硫化法製作鈮(Nb)摻雜的二硫化鉬,P型的鈮摻雜可提升載

子摻雜濃度用以降低金半介面的接觸電阻,透過不同製程方式製作頂部接觸和邊緣接觸的兩種金半介面結構,傳輸線模型(TLM)分析顯示出,邊緣接觸結構比頂部接觸結構的接觸電阻率低了兩個數量級以上,並藉由數值疊代方式得知層間電阻率是導致頂部接觸結構有較高接觸電阻率主因,並指出邊緣接觸之金半介面在二維材料元件的潛在優勢。在電晶體研究上,我們使用化學氣相沉積(CVD)合成的二硫化鉬成功製作出單層N型通道元件,將此電晶體與記憶體元件相結合,用雙閘極結構將讀(read)與寫(write)分成上下兩個獨立控制的閘極,並輸入適當脈衝訊號以改變儲存在電荷儲存層的載子量,藉由本體效應(Body effect)獲得足夠大的

記憶區間(Memory window),可擁有高導電度比(GMAX/GMIN = 50)與低非線性度(Non-linearity= -0.8/-0.3)和非對稱性(Asymmetry = 0.5),展示出了二維材料在類神經突觸元件記憶體內運算應用上的可能性。除了與記憶體元件結合外,我們亦展示二維材料電晶體作為邏輯閘的應用,將需要至少兩個傳統矽基元件才可表現的邏輯閘特性,可於單一二維材料電晶體上展現出來,並在兩種邏輯閘(NAND/NOR)特性作切換,二維材料的可折疊特性亦具有潛力於電晶體密度提升。我們進一步使用電子束微影系統製作奈米等級短通道元件,首先使用金屬輔助化學氣相沉積 (Metal-as

sisted CVD)方式合成出高品質的二維材料二硫化鎢 (WS2),並成功製作次臨界擺幅(Subthreshold Swing, S.S.)約為97 mV/dec.且高達106的電流開關比(ION/IOFF ratio)的40奈米通道長度二硫化鎢P型通道電晶體,其電特性與文獻上的二硫化鉬N型通道電晶體可說是相當,可作為互補式場效電晶體。另一方面,深入了解二維材料其材料特性後,可知在厚度縮薄仍可保持極高的機械強度,有潛力作為奈米片電晶體的通道材料。故於論文最後我們針對如何透過對元件製作優化提供了些許建議。
