Catapult Launch Fatigue Investigation of the Model E-1B/C-1 Airplane

Abstract

A laboratory fatigue investigation was performed on an E-1B fuselage with a reinforced catapult keel to determine if it could sustain the loads associated with 3,000 catapult launches. The bulkhead at fuselage station 135 failed after 8,420 test cycles of the catapult start of run condition. Using a test scatter factor of 2, this is equivalent to 4,210 service catapult launches. The holdback structure failed after 8,188 test cycles of the catapult release condition. Again, using a test scatter factor of 2, this is equivalent to 4,094 service catapult releases.
