DARPA's X-65 experimental aircraft nears flight testing phase

🔑 Enhanced Key Takeaways

• •The X-65 is part of DARPA's CRANE (Control of Revolutionary Aircraft with Novel Effectors) program, which aims to optimize aircraft design by removing complex mechanical moving parts.
• •The aircraft features a modular design, allowing for the testing of different wing configurations and active flow control actuators to validate performance across various flight regimes.
• •Active flow control (AFC) technology uses pressurized air jets to manipulate the airflow over the wing surfaces, providing control authority that traditionally required heavy, maintenance-intensive flaps and slats.
• •The X-65 is a full-scale, uncrewed X-plane designed to demonstrate that AFC can provide sufficient control for high-speed flight, potentially enabling stealthier and more efficient airframe designs.
• •Aurora Flight Sciences, a subsidiary of Boeing, is leveraging advanced computational fluid dynamics (CFD) and wind tunnel testing data to refine the AFC nozzle placement and pressure requirements prior to the first flight.
