The Lockheed Martin X-55 is a test vehicle as part of the US Air Force's Advanced Composite Cargo Aircraft (ACCA) program .
description
The X-55 is a modified version of the Dornier 328JET that was converted by Lockheed Martin in the Skunk Works as part of the ACCA project . The project was designed by the Air Force Research Laboratory of the US Air Force and is used to research new composite materials . The fuselage was replaced by a 16.8 m long and 3.05 m wide plastic cell in order to achieve weight savings. In particular, it should be determined whether the lighter plastic cell can withstand the high loads and enables lower maintenance cycles. The entire ACCA program serves as basic research for an as yet undefined successor model for the heavy strategic C-5 transporter.
