NASA署長艾薩克曼展示神秘飛行器剪影,暗示重啟高空高速飛行研究

Quick Look

NASA署長艾薩克曼在公開場合展示一架神秘飛行器剪影,外型類似SR-71「黑鳥」,並暗示NASA將重新投入高空高速飛行研究,但未確認是否為實際研發計畫。

AI-generated summary

Why It Matters

SR-71「黑鳥」是美國冷戰時期的高空偵察機,飛行速度超過3馬赫,曾被NASA用於航空研究,直至1999年退役。洛克希德馬丁曾提出SR-72概念機,但計畫後來沉寂。

〔記者吳哲宇/綜合報導〕NASA可能正在醞釀新一代高速X-飛機,NASA署長艾薩克曼(Jared Isaacman)近日公開一架神秘飛行器剪影,其修長機體、後掠翼及高度融合外型立即讓外界聯想到SR-71「黑鳥」偵察機。面對主持人直接追問,他不僅沒有說明機型,反而反問「你確定那是黑鳥嗎?」並強調NASA準備重新投入「高空、高速」飛行研究。

軍聞網站《The War Zone》報導,艾薩克曼上週在洛杉磯All-In峰會演說時,以「重建我們的X-飛機機隊」為題展示神秘剪影。他表示,NASA目前以X-59研究低噪音超音速飛行,「但這只是一個開始」,隨著NASA重新投入飛行測試並與產業界合作,未來將再次飛得像數十年前一樣高、快,「甚至更高、更快」。

請繼續往下閱讀...

主持人隨後直指照片就是SR-71,艾薩克曼卻反問「你確定那是黑鳥嗎?」當被追問究竟是什麼時,他只回答:「NASA正重新回到高空、高速飛行的行列」。

SR-71具備超過3馬赫飛行能力,雖以冷戰時期戰略偵察聞名,但NASA也曾用於航空研究,並持續操作至1999年。洛克希德馬丁則曾提出後繼「SR-72」構想,甚至規劃打造戰鬥機尺寸驗證機;不過多年公開討論後突然沉寂,目前計畫狀態不明。

報導指出,NASA展示的剪影是否代表真正存在的研發計畫仍無法確認,政府與軍火商也經常以概念圖呈現未來技術,因此不能據此認定神秘新機已進入研製。

不過,艾薩克曼確實正積極重建NASA的X-飛機研發體系。他去年12月上任第2天便要求擴大X-飛機計畫,今年3月更表示,NASA應頻繁試飛實驗機。

目前NASA最新X-飛機為X-59,今年6月首次突破音障、達1.1馬赫,未來目標為1.4馬赫;相較SR-71約3.3馬赫紀錄仍有巨大差距,但X-59主要任務是研究降低音爆,而非追求極速。

NASA今年4月另啟動「航空飛行加速器」(AFA),希望新技術在3年內進入飛行測試,研究範圍明確涵蓋超音速與高超音速。2027財年預算也把高速飛行列為重點,強調相關技術除航空運輸外,也可強化國家安全能力。

What to Watch

Space computing power, “connection” is the key

China is promoting the development of space computing satellites, from single-satellite computing to constellation networking and then to computing satellite networks. Data processing is realized in orbit through inter-satellite interconnection, and the response speed is improved to minutes or seconds. It is used in fields such as weather warning and wildfire monitoring. However, it faces technical challenges such as heat dissipation, cost and scheduling. National policies support the development of commercial aerospace to accelerate the construction of the space Internet.
