NASA engineers initiated a groundbreaking study in March, using a network of ground sensors to gather data from an experimental air taxi. Their goal? To safely integrate air taxis into urban airspace, regardless of weather conditions. This research focuses on collision avoidance and landing operations, ensuring efficient and safe air transport.
Over the years, NASA explored how wind, shaped by buildings and terrain, influences aircraft performance. The current study examines another type of wind—generated by the aircraft itself. Using Joby Aviation’s air taxi demonstrator, researchers collected airflow data near NASA’s Armstrong Flight Research Center in Edwards, California. The Joby aircraft’s six rotors allow for vertical takeoffs and landings while tilting for lift during flight.
NASA observed how the air pushed by the rotors creates turbulent, circular wind patterns. These turbulence effects are crucial, impacting not only the aircraft itself but also nearby aircraft and individuals on the ground. Measuring this turbulent wind proves challenging. Therefore, NASA upgraded its sensors with advanced lidar technology. This system employs lasers to precisely measure distances, mapping out wind patterns effectively.
“Understanding the turbulence effects is vital for safe, efficient flights,” a lead researcher emphasized. Alongside the ground sensors, NASA established additional monitoring nodes, including radar, cameras, and microphones. These nodes will track the air taxi’s movements over time, providing rich data for analysis.
This distributed sensing technology will play a key role in future air taxi operations. By tracking aircraft in urban traffic corridors, it enhances collision avoidance and improves air traffic management. “Our early research offers a chance to test technologies critical for airspace monitoring,” a project lead noted.
Additionally, the data from this experimental study will help refine the technology necessary for safer air taxis in busy areas. This research supports companies developing air taxis and drones, underpinning advancements in the field.
Overall, NASA’s initiatives under its Advanced Air Mobility mission aim to provide vital data to guide the future of electric air taxis and drones, paving the way for innovative transportation solutions in urban settings.
