Abstract
This paper presents an analytical approach for investigating speed effects on airframe noise for arriving and departing aircraft. Initial results showing the relative magnitude of airframe and engine noise are presented, along with a discussion of implications for modeling of noise-optimized advanced operational procedures. Older generations of jet engines produced significantly more noise than current-generation products, resulting in engine noise being the dominating contributor to overall noise when current environmental models were originally developed. The assumption that jet noise dominates airframe noise sources may have been reasonable in previous environmental impact studies. This paper illustrates the importance of modeling velocity effects on noise for advanced operational procedures.
