DARPA X-Plane Designed To Maneuver With Just Bursts Of Air Finally Gets Its Wings

Summary

Aurora Flight Sciences, a Boeing subsidiary, has announced a significant milestone in the development of the X-65 experimental drone under DARPA's CRANE program, with the aircraft's triangular wings now being integrated at its Virginia facility. The X-65 is a groundbreaking aircraft that uses Active Flow Control (AFC) technology, employing bursts of highly pressurized air through 14 embedded effectors to maneuver instead of traditional moving control surfaces like flaps and rudders. The drone features a unique Co-Planar Joined Wing design with a 30-foot wingspan, weighs approximately 7,000 pounds, and is built as a modular platform to allow wing sections and AFC effectors to be swapped out for extended future testing. To reduce risk and establish performance baselines, the aircraft will be equipped with both traditional control surfaces and AFC effectors, with successive tests progressively replacing conventional controls with the air-burst system. Despite facing delays and cost overruns since the program launched in 2020, Aurora is now targeting a first flight in the coming year, with the technology holding significant promise for improving the stealth, efficiency, maneuverability, and reliability of future military and commercial aircraft.

Key Takeaways

  • 1. The X-65 experimental drone uses revolutionary Active Flow Control technology, replacing traditional moving control surfaces with bursts of pressurized air to achieve roll, pitch, and yaw movements
  • 2. Aurora Flight Sciences has completed a major construction milestone by delivering and integrating the aircraft's triangular Co-Planar Joined Wings, moving the program closer to its first flight target
  • 3. The modular design of the X-65 allows wing sections and AFC effectors to be easily swapped, ensuring the aircraft can serve as a long-term test platform beyond the CRANE program
  • 4. AFC technology offers substantial benefits including improved aerodynamic efficiency, reduced weight, fewer mechanical failure points, lower maintenance requirements, and enhanced battle damage resilience
  • 5. The elimination of traditional control surfaces is particularly valuable for stealth aircraft design, as conventional moving surfaces create radar cross-section vulnerabilities that AFC technology could potentially eliminate
