The Defense Advanced Research Projects Agency (DARPA) is poised to launch its futuristic X-65 aircraft in 2025, ushering in a new era of flight control technology.
Spearheaded by DARPA's Control of Revolutionary Aircraft with Novel Effectors (CRANE) program, the X-65 represents a paradigm shift in how aircraft are controlled, eliminating traditional moving surfaces such as flaps and rudders.
The Future of Flight Control
Since the inception of aviation, control surfaces like rudders, flaps, elevators, and ailerons have been integral to maneuvering aircraft.
However, Space.com tells us that the CRANE program seeks to rewrite this narrative. The X-65, developed in collaboration with Aurora Flight Sciences, is designed to be controlled entirely by jets of pressurized air, a groundbreaking technology known as active flow control (AFC) actuators.
This innovation aims to enhance performance, reduce weight, and simplify mechanical complexities in aircraft design.
What is the X-65?
"The X-65 conventional surfaces are like training wheels to help us understand how AFC can be used in place of traditional flaps and rudders," explains Richard Wlezien, program manager for CRANE.
"We'll have sensors in place to monitor how the AFC effectors' performance compares with traditional control mechanisms, and these data will help us better understand how AFC could revolutionize both military and commercial craft in the future."
AFC Technology in Action
The AFC technology on the X-65 involves jets of pressurized air manipulating the airflow over the aircraft's surfaces.
This method contrasts sharply with the century-old approach of using external control surfaces, marking a significant departure from the norm.
This shift is not merely experimental; it could pave the way for future aircraft designs that are lighter, more streamlined, and potentially stealthier.
According to DARPA, removing traditional control surfaces could lead to performance enhancements by reducing weight, drag, and mechanical complexity, offering a glimpse into the future of aviation. (via Defensescoop)
Aircraft Features and Modular Design
The X-65, an unmanned aircraft with a 30-foot wingspan and a weight exceeding 7,000 pounds, is comparable in size and speed to a military trainer aircraft.
The modular design allows for the interchangeability of wings and AFC systems, providing versatility for extended testing post the CRANE program.
The aircraft's maiden flight, slated for the summer of 2025, is eagerly anticipated as a crucial step in validating the AFC technology.

Timeline and Industry Collaboration
DARPA's CRANE program, comprising multiple phases, has seen collaboration with industry leaders such as Aurora Flight Sciences and Lockheed Martin.
Having completed the preliminary and detailed design phases, the X-65 is now in the manufacturing stage, with Aurora Flight Sciences at the helm.
The project, initiated in 2021, has progressed steadily, successfully completing a critical design review. The involvement of these industry giants underscores the significance of the X-65 project and its potential impact on future aviation technologies.
Anticipating the Future
As the X-65 inches closer to its 2025 maiden flight, anticipation is mounting within the aerospace community. The unique blend of conventional control surfaces and cutting-edge AFC technology makes the X-65 a testbed for future aviation advancements.
