Ground-mounted microphones would pick up ultralow-frequency sound waves produced by clear-air turbulence, the leading cause of inflight injuries and fatalities
12 April 2021 The HiDRON stratospheric glider, a joint project between UAVOS and STRATODYNAMICS, has successfully carried out its regular test flight. UAVOS’ operators launched the stratospheric aircraft from a high-altitude balloon carrying a technology supported by NASA’s Flight Opportunities program successfully deploying an experimental payload to 24 km altitude and back. Extensive testing was performed to test operation in high altitude flight regimes utilizing UAVOS’ autopilot system and payload test services. A launch routine was tested allowing a safe transition from free-fall t...
1 April 2021 Whether it’s in the wake vortex of airplanes taking off or in seemingly calm air, there are few issues more meddlesome to flight than turbulence. Not only can these “horizontal tornadoes” make air travel uncomfortable and possibly dangerous, but attempts to avoid them can consume large amounts of fuel. Researchers at NASA have developed technology to find these zones, and with some engineering ingenuity, they could revolutionize both flight planning and aeronautical research. Not Your Typical Microphone Everything in the atmosphere can make a sound. Volcanoes rumble, waterf...
