Survey of Semi-Empirical Jet Noise Models for Preliminary Aircraft Engine Design

Scientific research studies on jet noise generation have been ongoing since the early 1950s, when turbojets were first used in commercial aircraft. Several numerical methods developed with aim of reducing environmental issues related to impact community annoyance. Among them, development fast and comprehensive tools for prediction captured attention researchers engineers, being very useful preliminary design phase aircraft engines. This work deals an extensive survey James R. Stone’s models, initially formulated National Aeronautics Space Administration (NASA) by Modern Technologies Corporation (MTC), their implementation a contemporary framework. The models are validated simulating different engine settings nozzle configurations taken from literature main scope highlighting strengths weaknesses semi-empirical formulations setting guidelines effective use during phases next supersonic
