Pioneering Plane's Flight Delayed: A New Way to Steer

A futuristic aircraft, the X-65, is set to take to the skies in late 2027, pushing back its initial flight date by over two years. This experimental plane, crafted by Aurora Flight Sciences, a Boeing subsidiary, is part of a Defense Advanced Research Projects Agency (DARPA) initiative. Its unique feature? It steers using bursts of air instead of traditional mechanical parts like flaps and rudders. The X-65 is designed to test "active flow control, " a concept that uses air bursts to alter airflow over the wings, causing the plane to shift direction. This method is more energy-efficient and could lead to lighter, more aerodynamic aircraft. DARPA's goal is to revolutionize aircraft design, making it more efficient and less complex. In January 2023, Aurora Flight Sciences received a $42 million contract to design the aircraft. By late 2023, the program passed a critical design review and moved into its third phase, where a full-scale prototype was built. Initially, the plane was expected to start flight tests in summer 2024, with a 30-foot wingspan and a top speed of Mach 0. 7. However, the program faced setbacks. The costs to produce the prototype exceeded expectations, leading DARPA to pause development and restructure the program. In August, a new partnership was formed, with Aurora becoming a co-investor. This restructuring aimed to make the project more affordable for the government. Despite these challenges, the X-65's construction is on track to finish in January. Ground testing is expected to begin late next year or in early 2027, with flight tests following in late 2027. The plane will feature 14 effectors across its flying surfaces to produce the necessary air bursts. Aurora Flight Sciences remains optimistic, stating that the X-65 will be an enduring flight test asset. The technologies and data from this project could pave the way for future aircraft designs and research missions.
