Boeing HH-47 CSAR Mock-up

This Combat Search and Rescue (CSAR) mockup, given to the museum by Boeing, consists of a CH-47 Chinook airframe without the forward and aft pylons, engines or
transmissions. It was utilized as an engineering mockup demonstrator for the U.S. Air Force CSAR-X competition.

The airframe was initially a CH-47 medium transport helicopter, accumulating 3 248 aircraft hours in 14 years of service in several U.S. Army units. Later, it became the first aircraft inducted into the MH-47D program, and then modified for Special Operations Forces.

In September 2005, the airframe started its third life as the engineering mockup demonstrator for the CSAR-X competition. It was on tour with
Boeing from November 2005 to March 2009 and travelled 20,420 miles in nine states.

Although Boeing won the CSAR­ X competition, the Air Force subsequently cancelled the program and the mockup aircraft was donated to the museum for display.
