    The NASA Quiet Engine Programme. (1971)
    In:  Other Sources
    Details
    Publication Date: 2011-08-16
    Description: Discussion of the experimental Quiet Engine developed under the NASA program to reduce jet aircraft noise levels. The current status of the program is given as follows: Aerodynamic evaluation of the three fans is complete and their acoustic evaluation is partially complete. Tests of fan casing boundary-layer section and of serrated leading edges on the half-scale B fan are complete and are underway on the half-scale C fan. Tests of the first engine with the A fan began in August 1971.

    The NASA Quiet Engine. (1971)
    In:  Other Sources
    Details
    Publication Date: 2019-07-27
    Description: The NASA Quiet Engine Program will incorporate all available noise-reduction technology into a propulsion system suitable for subsonic civil transport aircraft. Full-scale experimental hardware is being built and tested primarily for noise performance. The program is in process, and component tests to date indicate that it is possible to achieve or exceed noise reduction objectives of 15-20 PNdB below the levels of 707/DC-8 long-range transport aircraft.

    The NASA quiet engine program (1972)
    In:  CASI
    Details
    Publication Date: 2019-07-13
    Description: Initial studies on the design and testing of the quiet engine are described. The principal noise sources considered in the engine selection were the fan machinery noise and the fan and core jet noise. Nacelle acoustic linings are also mentioned. Fan and engine tests are discussed briefly and results indicate that it is possible to achieve or exceed noise reduction objectives of 15 to 20 PNdb below the levels of 707/DC-8 long-range transport aircraft.

    Technology - The essential base (1979)
    In:  Other Sources
    Details
    Publication Date: 2019-08-13
    Description: Establishing the technology base for building a strong viable space program is a complex systems problem which demands continuous attention with full recognition of the dynamic state of the environment in which we operate. In the present paper, an attempt is made to outline, in a condensed form, NASA's approach to selecting those technologies which deserve to be pursued and ensuring that the probability of selecting the right technologies is maximized.
