The “nearside” plenum door (NPD) at the 39-year-old NASA Langley Research Center (LARC) National Transonic Facility (NTF) has become increasingly recalcitrant during the opening /closing sequence. The NPD is the primary means of entry into the test section for personnel and for model installation. The sliding NPD hardware guide bearings have failed three (3) times within a one-year period and “quick fixes” were able to be made to guide rails, wheels and bearings to put the NPD back into operation. The NPD no longer can utilize a “quick fix” as the rolling hardware is at its limit for further modifications. This presentation will describe the NPD situation, the findings as to the cause of the periodic NPD failures, and the solution to remove, refurbish, and reinstall the NPD.
