In a groundbreaking achievement, researchers at NASA’s Langley Research Center in Hampton, Virginia, have successfully flown multiple drones beyond visual line of sight without a visual observer. This major milestone paves the way for the advancement of self-flying capabilities in the field of air taxis. Through years of research and collaboration with the Federal Aviation Administration (FAA), NASA’s innovative automation and safety systems have proven their reliability in autonomous flight operations.
The experimental flights conducted at NASA Langley demonstrate the remarkable progress in automation and safety in drone technology. By observing the behavior of smaller drones as they navigate and avoid obstacles, researchers can gather invaluable insights into how self-flying air taxis can safely operate when integrated into busy airspace. Through this method, NASA can ensure that the automation technologies designed for air taxis are capable of withstanding the demands of high-volume air traffic in urban environments.
NASA is not limiting its research to drones alone; the agency is also testing the elements of automation technology using helicopters. This strategic approach allows for a thorough evaluation of the autonomy features of these vehicles before they are deployed for passenger-carrying purposes. NASA understands the complex nature of operating air taxis in close proximity to airports and within communities, and is committed to ensuring the highest level of safety in these environments.
To facilitate the widespread adoption of advanced air mobility (AAM), where drones and air taxis will operate simultaneously, NASA has been actively developing and testing software solutions. During the flight tests conducted at the City Environment for Testing Autonomous Integrated Navigation test range, NASA employed the ALTA 8 Uncrewed Aircraft Systems (drones). These drones were equipped with sophisticated software that enables airspace communications, flight path management, and coordination with other vehicles. Such capabilities are crucial to ensuring safe and efficient operations in a high-density air traffic scenario.
As a recognized leader in aviation technology, NASA aims to contribute to the industry’s advancement by transferring the knowledge and technology developed during their projects. By making this technology publicly accessible, NASA enables industry manufacturers to access and utilize their advanced software solutions while designing and producing their own vehicles. This transfer of technology will undoubtedly benefit the industry as a whole and accelerate the realization of safe, reliable, and efficient air taxi services.
NASA’s research includes the development and testing of several key technologies. One such technology is ICAROURS (Integrated Configurable Architecture for Reliable Operations of Unmanned Systems), which provides autonomous detect-and-avoid capabilities. By ensuring the drones can maintain a safe distance from other air traffic, ICAROURS contributes to the overall safety and reliability of self-flying vehicles. Another technology employed is NASA’s Safe2Ditch system, which enables drones to autonomously identify and select the safest landing location in the event of an in-flight emergency.
NASA’s AAM mission encompasses multiple projects, each contributing to various aspects of research. The High Density Vertiplex project, specifically focused on the evaluation of vertiports or vertiplexes, explores where air taxis can take off and land at high frequencies. By addressing the technology advancements necessary for managing multiple vertiports in close proximity to one another, NASA aims to pave the way for a seamless and efficient integration of air taxi services into urban landscapes.
The successful flights of drones beyond visual line of sight by NASA’s Langley Research Center represent an immense leap in the development of self-flying technology. Through their intensive research, NASA has demonstrated that automation and safety systems can be effectively deployed to ensure the safe operation of air taxis in a future dominated by advanced air mobility. By sharing their innovative technology and expertise with the industry, NASA further facilitates the realization of a future where self-flying air taxis offer a safe, innovative, and efficient mode of transportation.
