EVALUATION OF C7 CATAPULT SERVICE CHANGE 140

Abstract

Installation of a catapult service change was considered a probable cause of excessive airplane nose gear loads during shipboard catapult launchings. Installation of the change in the C7 catapult at the Naval Air Test Center did not significantly alter airplane nose gear loads or catapult performance. Reduction of the flat plate launching valve orifice size from the 0.213 to 0.191 in. with the service change installed reduced C7 catapult endspeeds 4 to 5 kt. It is recommended that the specified launching valve orifice (0.213 in.) be utilized in the installation of Catapult Service Change 140. (Author)
