Bell Textron has been selected to proceed to Phase 1B of the Defense Advanced Research Projects Agency’s (DARPA) Speed and Runway Independent Technologies (SPRINT) X-Plane program. This significant development underscores Bell’s pivotal role in advancing the next generation of air mobility platforms through the exploration of enabling technologies and integrated concepts aimed at achieving a transformative blend of aircraft speed and runway independence.
The SPRINT program is geared towards the design, construction, and flight testing of an X-Plane—an experimental aircraft intended to demonstrate the essential technologies and integrated concepts essential for future air mobility platforms. Having successfully completed Phase 1A, which included a conceptual design review, Bell is poised to embark on preliminary design efforts for the SPRINT X-Plane.
Jason Hurst, Executive Vice President of Engineering at Bell, expressed enthusiasm regarding the company’s progress, stating, “We completed our initial risk reduction efforts with our sled test demonstration at Holloman Air Force Base, and we look forward to building on this success with our continued work with DARPA.”
Bell’s risk reduction testing at Holloman Air Force Base in late 2023 showcased several key technologies, including folding rotor, integrated propulsion, and flight control systems. Leveraging its investment in High-Speed Vertical Takeoff and Landing (HSVTOL) technology, as well as its extensive experience with X-plane development, Bell is well-positioned to contribute to the advancement of the SPRINT X-Plane program.
The HSVTOL technology pioneered by Bell combines the vertical takeoff and landing capability of helicopters with the speed (exceeding 400 knots), range, and survivability of jet aircraft. With over 85 years of experience in developing high-speed vertical lift technology, Bell has played a pioneering role in shaping innovative VTOL configurations, including the X-14, X-22, XV-3, and XV-15 for NASA, the U.S. Army, and the U.S. Air Force. Drawing from its rich history of fast flight, which includes the iconic Bell X-1, the company continues to push the boundaries of aviation innovation.
