世界一流宇航公司對亞軌道軍事運輸表示興趣
[據《國際飛行》雜誌2009年3月19日報導] 美國國防工業的一些大型公司開始對亞軌道飛行潛在的軍事化應用展開研究。諾格公司、普拉特惠特尼集團以及阿連特技術系統公司(ATK)都已經在一次內部會議上向美國政府的國家太空安全辦公室(NSSO)提交亞軌道運輸建議書。
2月24-26日,NSSO舉辦了一次科技論壇,號召從事亞軌道旅遊業的公司提供議案。但是幾家一流的宇航公司也受邀出席會議,另外還包括美國空軍研究實驗室、太空與導彈司令部以及NASA的商業乘員與運輸辦公室。
除一流宇航公司以外,亞軌道航太飛行公司也出席了這次內部會議。它們包括:Rocketplane公司、Xcor宇航公司以及秘密研製亞軌道火箭和太空艙的Blue Origin公司。
Blue Origin公司的高級顧問羅伯特•米爾曼與私人航太飛行聯盟主席佈雷特•亞歷山大共同做了大會報告。E’Prime 宇航公司也做了關於美國太空飛機系統的報告,該公司曾利用美國“和平衛士”(Peacekeeper )洲際彈道導彈技術研製火箭。其中提到的飛行兩用機理念類似于NASA艾姆斯研究中心上世紀60年代M-2的設計。E’Prime一直在爭取擺脫國際條約對洲際彈道導彈技術的束縛,以及管理和資金上的挑戰。維珍銀河公司只作為觀察者參加。
NSSO對近場技術表示興趣。近場技術能夠在2小時內執行發射,並可在2小時的飛行時間內將200千克重的有效載荷送到9250千米外的目標位置。2月,NSSO發佈一項包含上述要求的徵求書,並且表示更感興趣的是能夠通過亞軌道將13360千克重的載荷送入戰區的能力。各公司已經在3月15日之前提交資料。預計建議書徵求將隨後發佈。
這個2小時的回應要求與美國國防部的作戰及時回應太空辦公室的要求類似。 作戰及時回應太空辦公室曾在2006年授予諾格公司運載火箭調查合同,並在2008年12月授予ATK公司首顆衛星的子系統合同。 (中國航太工程諮詢中心 曲佳 侯丹)

Aerospace primes show suborbital military transport interest

Potential military applications for suborbital spaceflight are being studied by some of the biggest players in the US defence industry. Northrop Grumman, Pratt & Whitney and Alliant Techsystems (ATK) have all made suborbital transport proposals in closed sessions to the US government's National Space Security Office (NSSO), Flight International can reveal.
As reported earlier this month (Flight International, 10-16 March), an NSSO technology forum at Lackland AFB in Texas from 24-26 February featured proposals from companies associated with suborbital tourism. But it has emerged that several aerospace prime contractors also took part, along with the US Air Force Research Laboratory and space and missile command, and NASA's commercial crew and cargo office.
The NSSO is interested in near-term technologies that can launch on 2h notice and deliver within a 2h flight time a 200kg (440lb) payload to a destination 9,250km (5,000nm) away.
In February it released a request for information describing this and preferred future capabilities that included 13,360kg payloads being suborbitally delivered into theatre. The 2h response requirement is akin to the Department of Defense's Operationally Responsive Space office's needs. Companies had till 15 March to submit their information. A request for proposals is expected to follow.
As well as the aerospace primes, suborbital spaceflight companies also had closed sessions. These included Rocketplane, Xcor Aerospace and Blue Origin, which is developing its suborbital rocket and capsule in secrecy.
Blue Origin's general counsel Robert Millman gave a closed session presentation aided by Brett Alexander, Personal Spaceflight Federation president and a consultant to Blue Origin.
Alexander also gave a conference presentation about the commercial human spaceflight industry and told Flight International that "all the right people" were there from the DoD, but it is "nowhere near an acquisition". He says Blue Origin spoke about its suborbital activities.
E'Prime Aerospace, a company developing rockets using US intercontinental ballistic missile Peacekeeper technology, gave a joint closed session presentation with US Space Plane Systems, which has a lifting body concept that is similar to the NASA Ames Research Center's 1960s M-2 design. E'Prime has struggled with international treaty restrictions on ICBM technology, management board changes and funding challenges. Virgin Galactic only attended as an observer.
Under the Operationally Responsive Space office initiative Northrop was contracted to examine launch vehicles in 2006 and in December ATK won a subsystem award for the first satellite.
