Bell, Sikorsky Readying Acap Entries
Bell Helicopter Textron and Sikorsky Aircraft this month will begin initial composite layups of parts for their entries in the U.S. Army Aviation Research and Development Command’s Advanced Composite Airframe Program (ACAP). Bell and Sikorsky are in the second phase of the program, which entails manufacture and test of three complete airframes (AW&ST Apr. 13, 1981, p. 60).
