Stratolaunch是由泰图斯泰亿万富翁保罗·艾伦创立的航空航天公司,将世界上最大的飞机通过其第二次飞行试验,在第一次飞行后两年。

“我们是空中的!”Stratolaunch reported in a tweet

Today’s takeoff from California’s Mojave Air and Space Port at 7:28 a.m. PT marked the first time the plane, nicknamed Roc after the giant bird of Arabian and Persian mythology, got off the ground sinceStratolaunch 2019年10月的Cerberus资本管理收购

Roc rose as high as 14,000 feet and traveled at a top speed of 199 mph during a flight that lasted three hours and 14 minutes — which is close to an hour longer than2019年4月13日的第一次航班。在此期间,飞机最大速度为189英里/小时,最大高度为17,000英尺。

Zachary Krevor, Stratolaunch’s chief operating officer, said today’s flight accomplished all of its test objectives by checking the performance of improved instrumentation, a more robust flight control system and an environmental control system that allowed the pilots to work in a pressurized cockpit. Krevor said the crew included chief pilot Evan Thomas, pilot Mark Giddings and flight engineer Jake Riley.

当另一个猛烈的飞机的着陆齿轮落在跑道时,飞行的最佳时刻达到了达阵,而另一个仍然在空中。“我们最初在一个装备上触摸了,但这正是我们在跨越着陆期间使用的技术,”Krevor在降落后的电话会议期间告诉Geekwire。“虽然我们在我们的跨风限制内留下来,但我们确实有一点点跨越,而且机组人员做了一个很好的工作,使飞机降下来。”

自ROC在2019年的第一次飞行以来,这是商业模式10-year-old venturehas shifted: In its early years, Stratolaunch focused on using Roc as a flying launch pad for sending rockets and their payloads to orbit. The concept capitalizes on the air launch system pioneered by SpaceShipOne, which won financial backing from Allen andwon the $10 million Ansari X Prize in 2004,

The new owners still expect to use Roc for air launch, but the current focus is on using the plane as a testbed for Stratolaunch’s hypersonic flight vehicles, Once the plane is cleared for regular operations, perhaps next year, Stratolaunch could begin launching itsTalon-A prototype hypersonic plane

David Millman Stratolaunch的首席技术官表示,该公司计划建造三辆超音速。他说,应该为每17天至少开展一次过高度测试的方式,与20世纪60年代的X-15火箭飞机的航班速度相匹配,

超声波飞行在五倍的速度下,声速是军事应用的重要交易。据说俄罗斯和中国曾致力于过度武器制度,而美国军队热衷于保持。Stratolaunch期望其技术在五角大楼的计划中进行图。

“这正是我们正在寻找的领域之一:我们如何帮助国防部减轻所有广泛飞行测试的风险,”Millman告诉Geekwire。

Millman表示,Stratolaunch的Talon试验台将能够携带有效载荷,测试材料和飞行各种型材,这些档案可以帮助五角大楼确定超声波飞行的特点,然后才能进行昂贵的超声波车辆的昂贵的全吹飞行。

“What we’re doing is providing a path or them to test a lot of their technologies in a simpler way, in a repeatable way, in a useful way so that they can get to their all-up rounds much quicker,” Millman said.

Stratolaunch hasn’t ruled out eventually pursuing other applications for its launch system, including sending satellite payloads and船员空间飞机进入轨道。

Other companies,principally including Virgin Orbit,也在开发下一代空气发射技术。这种系统承担了更大的多功能性和更快的响应时间来启动有效载荷,因为运营机飞机可以从各种跑道起飞,在恶劣天气中飞行,从理论上在任何所需的轨道倾向中发射其有效载荷。

Stratolaunch的双胞胎机身,六个发动机ROC Airplane本身就在课堂上,凭借385英尺的世界纪录的翅膀。相比之下,修改波音747的翅膀畅通,处女轨道使用于211英尺。以前的记录架是云杉鹅,原型水上飞机1947年首次亮相并有一个320英尺的翅膀。由基于Mojave的缩放复合材料构建,Roc具有携带超过500,000磅的有效载荷的容量。
