Phase IV Jet Propellant (JP)-8 Fuel Performance Test. XM20 Bridge Erection Boat (BEB)

摘要

The primary mission of the bridge erection boat (BEB) is to assist U.S. Army Multi-Role Bridge Company (MRBC) units in maneuvering, construction, and operation of the improved ribbon bridge (IRB) during bridging and rafting operations. As a secondary function, the BEB can be used for safety boat, troop and cargo transport, and patrol and reconnaissance missions. The BEB is a 27- by 8-ft aluminum hull, twin engine, twin hydrojet powered vessel. The XM20 BEB is powered by twin Cummins 6BTA 5.9-L, six-cylinder, four-cycle 260-hp marine diesel engines equipped with in-line fuel injection pumps. Testing was performed from 27 November 2007 through 17 January 2008 at Spesutie Narrows Waterway, U.S. Army Aberdeen Test Center (ATC). This test was a follow-on effort to U.S. Army Test and Evaluation Command (ATEC) Project No. 2006-DT-ATC- BEBSX-D1897. The test objective was to determine if the Cummins XM20 engine and in-line fuel injection pump configuration were fully functional when operated with JP-8 fuel.
