Decades of VTOL research, autonomous systems development, and integrated testing continue to support the maturation of next‑generation vertical‑flight technologies.

Aurora Flight Sciences, a Boeing company, supports customers developing next‑generation vertical flight systems. With more than 30 years of experience in autonomy and rapid prototyping, the company provides an end‑to‑end ecosystem that helps customers reduce technical risk, validate performance, and bring advanced aerospace technologies to market faster.

A Proven Foundation in VTOL Innovation

Aurora’s legacy in vertical flight spans rotorcraft research, vertical takeoff and landing (VTOL) demonstrators, and advanced small unmanned aircraft systems (sUAS). Through this work, the company has developed a strong understanding of the unique challenges associated with vertical lift. Aurora applies that knowledge to structure development efforts around a progressive, risk‑reducing test approach. Early testing is conducted in controlled environments, with subsequent phases incrementally increasing complexity and fidelity as systems demonstrate readiness.

GoldenEye: Early VTOL Development

The GoldenEye family of ducted fan VTOL aircraft established Aurora as an innovator in unmanned vertical flight.

  • GE‑100, Aurora’s first VTOL aircraft, first flew in 2003 and served as the foundation for later aircraft.
  • GE‑50, introduced in 2004, explored patented free‑wing technology and fully autonomous flight. It also received three experimental airworthiness certificates from the FAA in 2007, enabling it to operate in the National Airspace System.
  • GE‑80, first flown in 2005 became the first ducted fan UAV to operate using a heavy fuel engine, advancing propulsion options for compact VTOL systems.

Aurora’s first unmanned vertical‑lift aircraft, the GE-100 prototype, completed its first flight in 2003.

Passenger Air Vehicle (PAV): Urban Air Mobility Prototype

Aurora’s electric VTOL Passenger Air Vehicle first flew in 2019 and contributed to industry efforts in autonomous urban air mobility. PAV was designed for fully autonomous operation and integrated intelligent flight‑management capabilities for each phase of flight. The program informed requirements and design considerations for future autonomous and electric vertical‑lift concepts.

Aurora’s autonomous eVTOL PAV prototype first flew in 2019.

Autonomous Aerial Cargo Utility System (AACUS): Human-Machine Teaming

AACUS was designed to demonstrate how autonomy could support cargo resupply for the U.S. Marine Corps. The system combined radar, LIDAR, and autonomy algorithms to convert a conventional helicopter into a pilotless platform capable of operating in challenging environments. AACUS was vehicle‑agnostic and required minimal operator training.

The American Helicopter Society (AHS) recognized the program with the 2018 Howard Hughes Award for contributions to rotorcraft technology.

Aurora initially tested AACUS on a Boeing unmanned H‑6U Little Bird and a Bell 206. In 2017, Aurora conducted a major demonstration at Marine Corps Base Quantico using a modified UH‑1 Huey known as AEH‑1. The aircraft completed an autonomous mission that included route selection, obstacle avoidance, landing zone adjustment, and final approach based on simple commands from a handheld tablet.

Simulation and Hardware-in-the-Loop Testing

Aurora’s Hardware‑in‑the‑Loop Simulator (HILSIM) allows engineers to evaluate flight-critical software and hardware in a controlled, high-fidelity environment before the aircraft ever leaves the ground. This capability supports early integration, shortens test campaigns, and reduces the risk sometimes associated with flight testing.

HIL simulation is a vital part of Aurora’s flight test process, reducing risk and shortening test schedules by validating software, hardware, and interfaces before an aircraft reaches the flight line.

The company’s flight simulation lab in Cambridge, MA supports applied research and prototype development, enabling engineers to rapidly prototype, test, and refine new aircraft technologies. The lab features a reconfigurable environment for autonomy testing and human machine integration. The lab has supported numerous research and development efforts, including the Pilot Cognitive Inference project, which used biometric sensors to analyze pilot workload and situational awareness.

Across simulation, UAS testing, surrogate aircraft, and optionally piloted flight, Aurora applies a consistent approach focused on credible data and progressive risk reduction. The company continues to support customers developing advanced VTOL and autonomous aircraft by providing technical expertise, established platforms, and a comprehensive test environment built for system maturation and validation.
