American Helicopter Museum & Education Center

The Museum’s collection contains over 16,000 items associated with rotary wing aviation. This includes books, technical papers, operating and maintenance manuals, photographs, videos, films, blueprints, hardware, and important historical artifacts. Our materials provide a documented window from the 1920’s to the present how autogiros/autogyros and single and tandem rotor helicopters have developed over time and continue to do so today. We highlight the birth of rotary wing research and production aircraft in the Delaware Valley by Harold Pitcairn, W. Wallace Kellett, Frank Piasecki, Arthur Young and others.

Researchers can request access to the Museum’s library and archives. For more information or to make an appointment, call the Museum at 610-436-9600 or send us an email at
