| UTM Wind Tunnel Test June 01, 2016  UTM Wind Tunnel Test team. Published aircraft performance data for multicopter, unmanned aircraft system (UAS) vehicles, such as quadcopters and octocopters (often referred to collectively as drones), are currently lacking. With the rapidly increasing popularity of such vehicles, researchers, system designers, and operators need to develop better models to accurately predict their performance and model their trajectories. To collect such performance data, a joint wind tunnel test was conducted in winter 2015 in the U.S. Army's 7-ft. by 10-ft. Wind Tunnel at NASA Ames Research Center (Moffett Field, CA). Three NASA Aeronautics Programs participated in this test: the Airspace Operations and Safety Program (AOSP)'s UAS Traffic Management (UTM) subproject, the Transformative Aeronautics Concepts (TAC) Program’s Design Environment for Novel Vertical Lift Vehicles (DELIVER) subproject, and the Advanced Air Vehicles Program’s (AAVP's) Revolutionary Vertical Lift Technology (RVLT) project. During this wind tunnel entry, five multicopter UAS vehicles were tested: 3D Robotics' SOLO and Iris+, DJI’s Phantom 3 Advanced, Drone America’s DAx8, and Straight Up Imaging's Endurance. Data on forces and moments, as well as electrical power as a function of wind speed, rotor speed, and vehicle attitude, were measured. The initial results were presented during the American Helicopter Society (AHS) International’s 72nd Annual Forum at West Palm Beach, FL, May 16-19, 2016. The Multicopter UAS Wind Tunnel Test Team's work, with contributions from the Aviation Systems Division (code AF) and the Aeromechanics Office (code AV), was also recognized with the Franklin Award for Outstanding Contribution to the Powered-Lift Field by the San Francisco Bay Area Chapter of AHS International. The award citation read: “For successful planning and execution of the first wind tunnel test performed to acquire experimental data for performance and acoustics of five multicopter unmanned aircraft systems in the Army 7- by 10-Foot Wind tunnel.” (POC: Jaewoo Jung) + Back to Top |
