Justin Hall lands the Dryden Remotely Operated Integrated Drone 2 (DROID 2) aircraft at NASA’s Armstrong Flight Research Center in Edwards, California, on Aug. 22, 2023, as part of the Advanced Exploration of Reliable Operation at Low Altitudes: Meteorology, Simulation and Technology campaign. The data gathered by studying wind from the ground to 2,000 feet could improve the safety of takeoff and landing for future air taxis and improve weather forecasts. DROID 2, a fixed wing aircraft, acted as a wind sensor during the study. The remotely piloted drone, with its 10-foot wingspan, flew repeated passes at different predetermined altitudes. It completed the last flights for the campaign on Aug. 31. See more photos from the wind study.

Rocky Garcia and Wesley James prepare a weather balloon to collect wind data at NASA’s Armstrong Flight Research Center in Edwards, California, on July 20, 2023. Researchers measured wind at altitudes below 2,000 feet using drones, sensors, weather balloons, and other technology during the Advanced Exploration of Reliable Operation at Low Altitudes: Meteorology, Simulation and Technology campaign. This information could fill knowledge gaps to resolve wind and weather unknowns that could hinder Advanced Air Mobility flights and to improve weather forecasts.

GE Aerospace and magniX have revealed the paint schemes of the hybrid electric aircraft they will fly as part of NASA’s Electrified Powertrain Flight Demonstration (EFPD) project. Under EPFD, GE Aerospace is developing a megawatt-class hybrid electric powertrain for ground and flight tests in the middle of this decade. Boeing and its subsidiary Aurora Flight Sciences are partnering with GE Aerospace to support the flight tests using a modified Saab 340B aircraft. The flight test campaigns will be based out of Aurora Flight Sciences’ facilities, including in Manassas, Virginia. For its demonstration, magniX is partnering with AeroTEC and Air Tindi to test its hybrid powertrain installed on a modified DeHavilland “Dash 7” aircraft. The flight test campaigns will be based out of the AeroTEC Flight…

NASA的X-59迈出了关键一步

NASA的X-59迈出了关键一步

ByNASA中文

NASA’s X-59 research aircraft moves from its construction site to the flight line – or the space between the hangar and the runway – at Lockheed Martin Skunk Works in Palmdale, California, on June 16, 2023. This milestone kicks off a series of ground tests to ensure the X-59 is safe and ready to fly. The X-59 is designed to fly faster than Mach 1 while reducing the resulting sonic boom to a thump for people on the ground. NASA will evaluate this technology during flight tests as part of the agency’s Quesst mission, which helps enable commercial supersonic air travel over land.

NASA’s X-59 sits in support framing while undergoing the installation of its lower empennage, or tail section, at Lockheed Martin Skunk Works in Palmdale, California, in this image from late March 2023. Once complete, the X-59 aircraft—the centerpiece of NASA’s Quesst mission—is designed to demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump. The Quesst mission will then fly the X-59 over several U.S. communities to gather data on human responses to the sound generated during supersonic flight and deliver that data set to U.S. and international regulators.

Hawaii’s big island and its two major volcanoes Mauna Kea and Mauna Loa rest under a partly cloudy sky on Feb. 8, 2022, in this view from the International Space Station. Mauna Loa, the world’s largest active volcano had been quiet for nearly 40 years. However, in 2022, the volcano began to stir, showing increased numbers of small earthquakes and subtle swelling of certain land surfaces in September. On Nov. 27, fountains of lava began spurting from the mountain’s Northeast Rift Zone and streams of molten rock flowed to the north. Ten days into the eruption, a NASA aircraft conducted its first flight over the erupting volcano. The aircraft carried NASA’s Uninhabited Aerial Vehicle Synthetic Aperture Radar system, which was used to map the volcano’s…

NASA is taking a leading role to help integrate new types of Advanced Air Mobility aircraft like air taxis and delivery drones into the sky, helping emerging markets to safely develop an air transportation system that moves people and cargo between places previously not served or underserved by aviation. NASA is working with private sector developers of electric vertical take-off and landing (eVTOL) aircraft, like Moog Surefly, to study the levels of noise ​they make. In this photo from summer 2022, the Moog Surefly vehicle hovers above an array of 28 ground-level microphones at Cincinnati Municipal Airport. The microphones picked up noise data, which researchers from our Glenn Research Center in Cleveland will analyze and share the data with Moog. Data from tests like the…

压力测试超级大黄蜂的翅膀

ByNASA中文

Teams at NASA’s Armstrong Flight Research Center in Edwards, California, recently completed stress testing on the Navy’s F/A-18E Super Hornet aircraft from the Naval Air Systems Command (NAVAIR) in Patuxent River, Maryland. The Super Hornet is seen here in a top view from March 2022 while in a wing loading test configuration at Armstrong. Understanding what stress, or strain, an aircraft can endure is critical to carrying out its intended mission. To better understand the aircraft’s capacity for strain, unique facilities can “load” the aircraft to specified stress points and document its performance. The test data resulted in the development of loads equations that calculate real-time loads experienced during flight testing, which can be compared to established design limits to ensure safety of flight and…
