【 摘 要 】

This report covers the entire effort of GE Global Research's NASA Prime Contract NNC15CA02C "Evaluation of Low Noise Integration Concepts and Propulsion Technologies for Future Supersonic Civil Transports". GE Global Research was supported by GE Aviation and Lockheed Martin in exploring the potential of wing shielding, flight path optimization, and jet noise technology to target aggressive community noise levels of 10 EPNdB lower than Chapter 14 for a future (mid-term) commercial supersonic transport aircraft.
