Boeing Asset Hydrofoil Advanced Surface Ship Evaluation Tool Module User Manual Vol 4B, Version 2, April 1986(0125)
The HANDE user manual and theory manual were combined into a single ASSET/ HYDROFOIL user manual. The Foilborne Hydrodynamic Module is a module in the ASSET/ HYDROFOIL synthesis process. Its primary purpose is to compute: 1) the foilborne drag at input design speed and design weight, 2) the foilborne drag at input range speed and at 50% fuel load, 3) the takeoff hump drag and corresponding speed, and 4) if requested, the waterjet propulsion system inlet duct area required for takeoff. The pertinent parameters calculated in the module are passed to the other modules via the current model. With the exception of the waterjet inlet duct sizing, the Foilborne Hydrodynamic Module does not modify foil/strut assembly geometric parameters, and its only output is the foilborne and takeoff drags and corresponding takeoff speed. Although this module is designed for integrated operation within the synthesis loop, it is capable of independent operation if desired; however, during independent operation, it must be recognized that to compute consis-tent drags, proper geometric input data will be required for both the hull and foil/strut assembly. All this input data enters the module through the current model. It should be noted that the exclusion of interfacing parameters during independent operation may lead to erroneous conclusions.
