Re: [PSUBS-MAILIST] Fwd: Analytical Hull Drag Techniques

[Kenneth Schulze <aquamari@cruzers.com>]

Greetings to all!
I've been quiet regarding the questions about drag and vacuum pressure at the base
of a vehicle, but I'd like to step in and recommend and excellent reference book.
The title is "FLUID-DYNAMIC DRAG" by Dr. S. F. Hoerner, 1965.  This book can be
purchased from Hoerner Fluid Dynamics, P.O. Box 65283, Vancouver, WA, phone: 360
576-3997.
This book covers an array of fluid dynamic shapes along with theory and test data.
There's even a section on water craft, surface and submerged.  Even though much of
this work was done for air craft, it really applies to any fluid medium, just be
sure to use the proper terms for water instead of air.
I hope this helps,
Ken Schulze
