Investigation of Internal Corrosion and Evaluation of Non-Skid Coatings on Mark 7 Jet Blast Deflectors
Abstract
The Mark 7 Jet Blast Deflector (JBD) is a 36 foot by 14 foot aluminum barrier erected at a 50 degree angle to the flight deck, for the purpose of protecting waiting aircraft and handling personnel from the jet blast of a plane being launched. In order to cool the panels enough to allow safe passage of personnel and machinery and to prevent actual physical damage to the JBD by the heat of the jet engines, sea water is pumped through the internal passages of the panels. Ships personnel, in the past, have reported that internal corrosion was a continuing maintenance problem, requiring frequent and costly rework. NAVAIRENGCEN undertook a program to assess the severity of corrosion damage occuring on the JBD's and to investigate potential methods for controlling internal corrosion. NAVAIRENGCEN also initiated a study to further evaluate the relative ability of metallic non-skid coatings to perform in the JBD carrier deck environment.
