NASA carbon fiber glider to gather weather data during flight
The teams are still working on the design but the aircraft is expected to have a wingspan of about 3 feet and will be made of double ply, carbon fiber.

NASA Armstrong Flight Research Center staff and students are working on a carbon fiber glider that could deliver more accurate, immediate and economical information on severe weather like hurricanes. Called the Weather Hazard Alert and Awareness Technology Radiation Radiosonde (WHAATRR) Glider, the vehicle could potentially save the National Weather Service up to $15 million a year compared to current methods and with faster and more reliable data, says project manager Scott Wiley.
In addition to NASA and the National Weather Service, the WHAATRR Glider could benefit the National Oceanic and Atmospheric Administration and potentially serve as an airborne sciences platform, Wiley says. The data obtained from such gliders could reduce costs incurred from unnecessary airline delays and potentially save aircraft and lives, he added.
Students and Armstrong staff have been developing the glider based on the Prandtl-M aircraft to fly in the atmosphere of Mars. The teams are still working on the design but the aircraft is expected to have a wingspan of about 3 feet and will be made of double ply, carbon fiber. One of the first tests will be an air launch from 20,000 feet from a weather balloon, Wiley says. Simultaneously, sensors, instrumentation and flight control software and hardware will be prepared for the aircraft’s ultimate test in the early development phase – a drop from 100,000 feet altitude and remotely piloted to a predetermined destination.
Another expected contribution of such vehicles is the ability to gather research to improve weather forecast models on Earth and in space. The glider development also could bolster the goal of flying on Mars to collect atmospheric information to inform exploration decisions.
