• Abstract:
  Naval Air Warfare Center Aircraft Division (NAWCAD) supported a series of engine stand tests led by the Federal Aviation Administration’s Civil Aerospace Medical Institute (FAA/CAMI) as part of a congressionally mandated aircraft air quality study. Experiments were conducted at the Kansas National Gas Machinery Laboratory (NGML) from May 16th to 19th, 2022. Engine tests simulated bleed air-contaminated events by injecting aircraft fluids into an engine system. NAWCAD collected 56 air samples using tri-bed sorbent tubes to detect Volatile Organic Compounds (VOCs) resulting from these events. Samples were processed and analyzed by Gas Chromatography- Mass Spectrometry (GCMS) per an adapted EPA TO-17 method at the Naval Air Station (NAS) Patuxent River. To the extent of the data, chemical analysis of the samples demonstrated that VOCs are present in the bleed air stream when aircraft fluids enter the engine system. Overall, each fluid category showed a distinctive VOC emission profile. However, significant residual fluid was observed between injections that negatively affected the chemical analysis of these emissions.
