Rocket noise models for the US Department of Defense

Accurate rocket noise prediction models are critical to support growing space defense programs. Potential deficiencies in the NASA SP-8072 model developed in the 1970s have been identified, but their impacts on accurate predictions are currently unknown. Cross-validationcomparisons to full-scale rocket measurements are needed to identify and quantify errors and to improve accuracy. This paper will review the DoD programs and policies that motivate rocket noise modeling requirements, summarize the current models in use, discuss some of the potential deficiencies of the models, and propose a roadmap for establishing confidence in models for official DoD use.
