X-plane: US high-speed, runway-free rotor aircraft ready for real-world testing

Bell Textron has completed wind tunnel testing for its rotor-folding aircraft under DARPA's SPRINT program, validating stability during in-flight rotor folding and unfolding. The aircraft is now prepared for flight demonstrations, aiming to enhance speed and achieve runway independence for future air mobility and combat operations. This innovative design combines vertical takeoff capabilities with high-speed flight using a retractable rotor system and jet propulsion, potentially benefiting special operations and agile combat employment in areas with limited runways.
