American Aerospace Technology Inc’s AiRanger™ (formerly the Resolute Eagle) unmanned aircraft system (UAS/drone) successfully completed a demonstration flight on February 25 as part of NASA’s Systems Integration and Operationalization (SIO) activities. The objective of the AiRanger demonstration was to tackle key challenges to enable routine commercial UAS operations in the National Air System (NAS), including development, integration, and certification of UAS and the technologies required for safe operation with manned and unmanned aircraft traffic in the NAS. Target applications are focused on critical infrastructure missions including beyond visual line-of-sight (BVLOS) patrols over pipelines, rail, road, and agricultural environments using multispectral sensors with integrated machine learning and communications for real-time delivery of threats to damage prevention specialists via a cloud-based platform. The operation was conducted in support of the SIO program’s goal to “work toward commercial UAS operations in the NAS.”

According to David Yoel, AATI CEO “America is increasingly managed by artificial intelligence (AI) and served by unmanned aircraft. The AiRanger™ BVLOS UAS operates at medium altitudes carrying advanced sensors and AI. We are transforming the way thatthe nation’s 500,000 miles of midstream pipelines are patrolled, providing a fundamentally new and unique capability that changes the way we manage health, safety and the environment, respond to disasters, optimize operations and leverage human capital.”

On display was the AATI-developed Detect and Avoid (DAA) system that enables AiRanger to fly safely in civil airspace alongside manned aircraft. The DAA system consists of dual airborne RADAR, ADS-B, tail and wing cameras mounted on the UAS. The system’s collision-avoidance radar provides an essential safety feature for integratingunmanned aircraft into civil airspace. The DAA system included an integrated Sagetech MXS ADS-B In/Out Transponder and ACAS-based DAA components.

“Our AiRanger platform, equipped with state-of-the-art cooperative and non-cooperative DAA sensing technologies, has the ability to provide a technological leap in safe operation of unmanned aircraft in Class G airspace in the NAS. Through collaboration with modeling and simulation experts at MIT Lincoln Laboratory and Johns Hopkins Applied Physics Laboratory, we are scientifically and methodically quantifying and mitigating collision risks” said Ali Etebari, PhD, VP and GM in charge of the AiRanger.

As part of the demonstration, American Aerospace Technology Inc’s AiRanger exhibited its ability to provide a wide variety of commercial and public services using onboard sensors. Services include inspections of hundreds of miles of rail, energy pipeline, powerline, windmill, and canal infrastructure, agriculture monitoring and topological surveys, as well as wildfire and flood monitoring, and maritime surveillance.

“The flight demonstration conducted by AATI highlights how unmanned aircraft can be used to detect pipeline leaks early, reducing the likelihood of environmental damage,” said Kurt Swieringa, NASA SIO technical manager. “This activity was a collaboration between NASA and AATI to make strides toward safe routine operations of UAS in the national airspace system.”

For the demo, the AiRanger departed from the Kern County Buttonwillow Airport (L62) near Bakersfield, CA, and flew a pre-determined pipeline route from the Shafter, CA area heading westbound at 2,000 foot altitude. According to AATI, data collected during the flight will be used to evaluate detect and avoid (DAA) and command and control (C2) technologies in support of future standards development and FAA certification guidelines. AATI’s partner for certification includes End State Solutions.

Charlton Evans, CEO of End State Solutions, “This demonstration will support key milestones in certification of UAS that don’t fall under Part 107 rules and require more rigorous certification processes so they can safely and seamlessly integrate into the National Airspace just like manned aircraft. This operation should inform standards about acceptable levels of safety. NASA’s support in promoting safe integration of UAS has served as a real catalyst for the industry.”

Complex coordination with the FAA, the Federal Communications Commission and local authorities was required for the flight to occur. The airspace authorization was established through the New Jersey Institute of Technology (NJIT) in cooperation with the New Jersey Innovation Institute (NJII).

The AiRanger is a rail-launch takeoff and skid landing aircraft design powered by an 8 horsepower engine. Carrying AATI’s InstiMaps™ Automated Threat Detection sensor solution, AiRanger completed its first operational proof of concept and effectiveness trials in November of 2020. The aircraft has a range of 75 nautical miles, top speed of 100 knots and can carry payloads of up to 65 pounds, including fuel and sensors.
