Ingenuity, the helicopter that arrived on the Red Planet on the Mars Perseverance rover, has made nine flights on Mars. Ingenuity’s historic achievement is the first powered helicopter flight on a terrestrial body other than Earth. According to Håvard F. Grip, Ingenuity Chief Pilot, and Ken Williford, Perseverance Deputy Project Scientist, Flight 9, wh...
左图：位于德克萨斯州圣安东尼奥的KBR设施的低压舱，通过降低舱内的气压来模拟非常高的海拔高度。舱内的实验对象经历了在更高海拔处存在的减压条件，在这种情况下，海拔高达60,000英尺。 右图:一名军事测试志愿者在接受快速减压前，穿着防护装备呼吸氧气。测试的目的是验证他使用和佩戴的设备以及生命支持系统都能正常工作。 影像来源：NASA 对于NASA的静音超音速飞行团队来说，安全是最重要的，他们正在为X-59静音超音速技术（QueSST）飞机未来的飞行测试做准备，并取得了长足的进步。为了给我们的飞行员实现最安全的环境和飞机，NASA正在与承包商KBR合作，并依靠他们的专业知识来确保飞机符合生命支持和紧急氧气系统达到所需的标准。 NASA的X-59是一架研究型飞机，旨在通过其安静的超音速技术和设计特点来消除音爆的轰鸣声...
In a series of flights between June 1-6, 2021, Stratodynamics Inc. launched its HiDRON stratospheric glider from a high-altitude balloon at Spaceport America in New Mexico. HiDRON carried technology supported by NASA’s Flight Opportunities program for the first time. The uncrewed HiDRON stratospheric glider from Stratodynamics is designed to release from a s...
In this March 2021 image, Flight Research Inc.’s Bell OH-58C Kiowa helicopter hovered over a helipad after completing an urban air mobility (UAM) approach at NASA’s Armstrong Flight Research Center. The Advanced Air Mobility National Campaign used the helicopter as a representative vehicle to better understand how a future UAM vehicle will need to operate in...
Credit：NASA 2020年，美国国家航空航天局（NASA）在月球到火星探测战略方面取得了重大进展，实现了阿尔忒弥斯（Artemis）计划的任务目标，取得了能够造福于人类的重大科学进步，并恢复了美国本土的载人航天发射能力。与此同时，NASA的专门小组迅速采取了行动，协助国家抗击新型冠状病毒肺炎（COVID-19）疫情。 NASA局长吉姆·布里登斯廷（Jim Bridenstine）表示：“NASA在疫情期间表现出的韧性和毅力给全国人民留下了深刻印象。我们与美国商业伙伴一起创造了历史，作出了开创性的发现，推动了科学进步，进一步深化了航空研究和技术研发，甚至还参与了抗击COVID-19疫情的斗争。我们度过了充满挑战的一年，取得了令人难以置信的成就，并为持续的成功开辟了道路。” NASA对美国联邦政府应对COV...
Dec. 11, 2020, marks the 50th anniversary of NASA’s Langley Research Center’s 14×22 Subsonic Wind Tunnel. The facility is used to assess aerodynamic performance of aircraft over a wide range of takeoff, landing, cruise, and high angle-of-attack conditions. It can provide acoustic, tethered free-flight, and forced-oscillation testing, motorsports researc...
An array of 960 microphones is seen here off the end of runway 11 at Boeing’s research facility near Glasgow, Montana. The microphones were used by NASA to record the sound of a low-flying 787-10 Dreamliner passing overhead as part of the Chicago-based company’s 2020 ecoDemonstrator program during late August and early September. NASA researchers are studyin...
