NASA has revealed a glimpse of its next X-plane, known as the X-70 Fractal.
Or at least what it thinks the X-70 will look like once built. The agency released a short statement on Wednesday (Nov. 4) announcing the X-plane, or experimental plane, declaring it to be a highly maneuverable test bed with a “rapidly reconfigurable flight-control technology,” allowing NASA to swap both external and internal components on-the-fly. This modular architecture will allow NASA to “explore aircraft maneuverability in ways never before demonstrated in crewed flight,” according to the agency’s statement.
The announcement was made alongside an AI-generated image showing two canted vertical tail fins emerging from swirling smoke. Little can be gleaned from the image about what final form the X-70 might take, but the tail fins are somewhat reminiscent of the Lockheed Martin F-22 Raptor or Boeing F/A-18 Super Hornet.
“The X-70 Fractal gives NASA a crewed, high-performance platform to test advanced flight-control, maneuverability, and other cutting-edge technologies in real flight,” NASA Administrator Jared Isaacman said in the statement. The NASA chief called the aircraft “just one part of this new beginning for aeronautics” and said that the agency expects the X-70 to make its first flight within two years.
“This is why people come to NASA: to build, to learn, and most importantly, to fly,” Isaacman added.
NASA’s statement fleshes out a few details about the X-70’s capabilities. According to the agency, Fractal will fly at a cruise speed of Mach .75, about the same as a Boeing 737 Classic. The X-70 will be able to reach altitudes of up to 45,000 feet (13.7 kilometers), and will have a range exceeding 1,726 miles (2,777 kilometers, or 1,500 nautical miles).
The X-70 Fractal will also be able to carry around 2,000 pounds (900 kg) of experimental payloads both internally and externally, which will allow for a “wide range of research and flight-testing opportunities,” NASA said in the statement.
NASA adds it will have a takeoff weight of 10,000 pounds (4,535 kilograms), around the same weight as the Scaled Composites- and Northrop Grumman-developed Model 437 Vanguard experimental aircraft. In fact, the two aircraft share a similar silhouette — at least in the AI image of the X-70 Fractal NASA has released so far.
The agency’s most recent X-plane, the X-59, has been flying for over a year. That jet features a radical long-nosed geometry without a forward windscreen; pilots fly by way of an augmented reality screen that combines views from sensors and a forward-facing camera.
That geometry dampens the shockwaves coming off of the X-59 when it flies faster than the sound barrier, allowing it to fly at speeds over Mach 1 without the thunderous sonic booms that typically accompany supersonic flight.
There are numerous experimental aircraft being developed by private companies, such as Boom Supersonic’s X-1 jet, which, like the X-59, aims to develop technologies that lessen the auditory impact of sonic booms on the ground.
In terms of other government X-plane projects, Boeing is working on the F-47, a next-generation stealth fighter for use by the U.S. military, and DARPA, the Pentagon’s research agency, has an X-plane project of its own known as CRANE.
