6 Diesel Fuel Can Hit by PELE An advanced weapon and space systems company31 Test Summary All targets were incapacitated except the APC at 5000 ft ground-to-ground. PELE ignited residual fuel in AC-130 wing foam and diesel fuel in5-gallon fuel can. The round met or exceeded performance projections. Air Force assessor. Air Force down-selected to the PELE round because Qualification Testing showed it to be as good or better than the PGU-28/B, especiallyif you factor in the life cycle cost advanced weapon and space systems company32 Conclusion20 mm x 102 mm PELE cartridge offers: Combined HE and KE performance characteristics 100% safe No reactive materials and no fuze High reliability and long shelf life Low cost standard materials, simple manufacturing, short lead times One round for all combat and training round (reduced logisticburden) Can be optimized for individual customer s requirements Ready for service ballistic match to PGU-27 and PGU-28/B, existingignition system and no impact to aircraft operating systems ( software) or handling equipmentPELE is an ideal form-fit-function tactical advanced weapon and space systems company33 Acknowledgements Diehl BGT Defence GmbH & Co.
