Abstract : On 20 May 1969 in Compressor Plant No. 1 of the Supersonic Wind Tunnels, Exterior Ballistics Laboratory, a stoppage of air flow through the labyrinth seals of the centrifugal air compressors caused about 20 gallons of lubricating oil to be drawn into the compressors and main air piping system used in the operation of the supersonic wind tunnels. Air seal operation, the oil problem and clean-up are discussed. (Author)
