A Review of Resistance Prediction and Design Methods for Strut-Pod Inlets,
Abstract
Two aspects of strut-pod waterjet inlet technology are reviewed in this report. First, hydrodynamic aspects of inlet design are discussed and various design methods are presented. Second, the subject of drag prediction is briefly reviewed, state-of-the-art drag prediction methods are presented and their predictive accuracy is compared. For superhigh speed applications (approximately 100 kts), a variable area concept with auxiliary strut vanes is recommended. For speeds below 50 kts, fixed area inlets should suffice. Intermediate speed applications should be investigated on a case-by-case basis to determine if auxiliary vanes are desirable. (Author)
