DM-3 Major Test Objectives

Overview

• Demonstrate compliance to ballistic performance requirements at a 90oF PMBT

• Assess ballistic predictions with high aft segment mach number and erosive burning at the 90oF PMBT requirement

• Assess reduced insulation thickness as it approaches the projected flight profile

Verify PBI-NBR field joint performance at the upper temperature requirement

• Evaluate aft dome flow characteristics and effect on insulation and boot at the 90oF PMBT requirement

• Verify nozzle erosion at the 90oF PMBT requirement

• Verify nozzle bondline performance at the upper extreme temperature requirement

• Evaluate FNR flat development and potential abnormal erosion

Assess performance of ENKA CCP in ply-lift prone locations

Evaluate nozzle contour change

• Evaluate silica cowl performance
