This week, a storm-chasing drone operated by researchers at 抖阴短视频 Boulder will get the blockbuster treatment when a version inspired by it appears in the summer popcorn flick 鈥淭wisters.鈥�

The RAAVEN drone was developed by researchers at 抖阴短视频 Boulder鈥檚 Integrated Remote and In-Situ Sensing (IRISS) program. It鈥檚 part of the Targeted Observation by Radars and UAS of Supercells (TORUS) project, a research effort that uses small drones and remote-sensing instruments to collect data on tornado formation in supercell thunderstorms. TORUS is led by principal investigator Adam Houston of the University of Nebraska-Lincoln. Brian Argrow and Eric Frew, professors in the Ann and H.J. Smead Department of Aerospace Engineering Sciences at 抖阴短视频 Boulder, are among the co-principal investigators for the project.

In trailer scenes for 鈥淭wisters,鈥� an uncrewed aircraft that matches RAAVEN swoops like a fighter jet toward storm clouds.

The RAAVEN鈥檚 appearance in the trailer surprised and delighted Argrow, its lead developer, when he first viewed it during the Super Bowl halftime this past February.

Argrow said he didn鈥檛 realize a blockbuster like 鈥淭wisters鈥� was underway when a film crew contacted him in April 2023 for permission to create a radio-controlled model of the RAAVEN. He directed the moviemakers to make arrangements with the drone鈥檚 airframe manufacturer.听

鈥淚 don鈥檛 usually watch the halftime show, so I was about to go downstairs when the trailer came on,鈥� he recounted. 鈥淚 was shocked. This really is a big movie! And as I was watching, the RAAVEN appears. I said to my wife: 鈥楧id you see that? That鈥檚 a RAAVEN!鈥欌��

However, the RAAVEN already is a star.

Since 2017, the 6-and-a-half-foot wingspan drone has played a leading role in TORUS, which combines drones and tracking vehicles to gather thunderstorm data. TORUS explores how supercell thunderstorms give rise to tornadoes, and the researchers hope to help improve tornado warnings across the country. The project also involves the National Oceanic and Atmospheric Administration鈥檚 National Severe Storms Laboratory, the University of Oklahoma's Cooperative Institute for Severe and High-Impact Weather Research and Operations and Texas Tech University.

The RAAVEN can fly as fast as 90 miles per hour and has a battery life of up to three hours, putting it ahead of standard rotary wing drones, which can鈥檛 keep up with storms moving at 30 to 60 miles per hour and often run short of battery life, Argrow said.

鈥淣o one else is doing what we do,鈥� he said, adding that it鈥檚 the RAAVEN and its mobile ground stations, authorized by the FAA, that make the research unique.
