    The CF6 Jet Engine Performance Improvement - Low Pressure Turbine Active Clearance Control (1982)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: A low pressure turbine (LPT) active clearance control (ACC) cooling system was developed to reduce the fuel consumption of current CF6-50 turbofan engines for wide bodied commercial aircraft. The program performance improvement goal of 0.3% delta sfc was determined to be achievable with an improved impingement cooling system. The technology enables the design of an optimized manifold and piping system which is capable of a performance gain of 0.45% delta sfc.
