Čaj Zvono XV-15 je eksperimentalni avion koji je pokazao izvodljivost i performanse tiltrotor tehnologije. Tiltrotor je vrsta aviona koji može poleteti i sleteti vertikalno kao helikopter, ali takođe može nagnuti svoje rotore napred da leti kao avion. Bell KSV-KSNUMKS je razvio Bell Helicopter Tektron u saradnji sa NASA-om i američkom vojskom u KSNUMKSs i KSNUMKSs. To je bio drugi uspešan tiltrotor avion posle Bell KSV-KSNUMKS, i prvi koji je postigao velike brzine leta preko KSNUMKS km / h. Bell KSV-KSNUMKS je imao dva turbovratila motora montirana na rotirajućim gondola na vrhovima krila, koji je vozio tri lopatice propelera koji bi mogli da funkcionišu kao rotora ili propelera.
The engines were connected by a driveshaft that allowed power transfer in case of engine failure. The aircraft had a fixed wing and a conventional tail with a horizontal stabilizer and a vertical fin. The pilot controlled the aircraft using a cyclic stick, a collective lever, and pedals, similar to a helicopter. The Bell XV-15 made its first flight on May 3, 1977, and completed its flight test program in 2003. During its 26 years of service, it performed over 200 hours of flight and demonstrated various capabilities such as hover, transition, cruise, autorotation, and crosswind landing. It also participated in several public demonstrations and air shows, attracting interest from both military and civilian customers. The Bell XV-15 paved the way for the development of the V-22 Osprey, a tiltrotor aircraft that entered service with the US Marine Corps and the US Air Force in the 2000s. The Bell XV-15 also inspired other tiltrotor projects such as the AgustaWestland AW609 and the Bell V-280 Valor.
