DTIC ADA450419: The National Shipbuilding Research Program. REAPS 5th Annual Technical Symposium Proceedings. Paper No. 19: Interactive Lines Generation (HULGEN) With a Storage Tube (User Guide)

Given the very minimum input of length, beam, draft, prismatic and midship section coefficients, LCE, LCF, and a deck at edge definition; HULGEN computes all of the initial parameters and control curves required to produce a body plan. This body plan is not the one desired, but provides a starting point for any variations the user wants to make. The SHIP HULL FORM GENERATOR (HULGEN) uses a piecewise polynomial development and representation of an early stage design ship's body plan. It was originally written for refresh. graphics scopes with light pens. Those earlier versions of the program, although done for light pen picks, operated in a way that made conversion to storage tube graphics very practical. The displays were changed very little and the interactive light pen picks were converted to keyboard entry menus. The user now types a menu option and/or data to proceed. HULGEN was developed specifically for the early stage design problem of developing many optional hulls rapidly. At this point in the design it is important to be able to determine whether the desired hull form can be developed from the gross dimensions and form coefficients available. Hull form generation is disti
