American Helicopter Museum

The American Helicopter Museum & Education Center (AHMEC) is located at 1220 American Boulevard, West Chester, Pennsylvania, United States. The transport museum focuses on rotary-wing aviation history, science and technology. The collection contains over 40 civilian and military autogyros, convertiplanes, and helicopters, including some early-generation models. The museum also has an extensive research library, the Renzo Pierpaoli Memorial Library, which contains documents, artifacts, films, and memoirs that museum members can use.

The museum strives to restore and display historic aircraft and chronicle the origin and development of rotary-wing aircraft. The museum's exhibits chronicle the efforts of pioneers like Harold Frederick Pitcairn, Mr. W. Wallace Kellett of Kellett Autogiro, Arthur M. Young and Frank Piasecki, and today it continues to record the new and ever-expanding role of the U.S. helicopter industry. The exhibits span the history of rotary-wing aircraft from the earliest rotorcraft to the latest developments in tiltrotor. AHMEC is one of only two museums in the world currently displaying a V-22 Osprey.
