Model Rocket Builder 4.0 PC FLOPPY design analyze build rocketry hobbyist tech! Type: Application Platform: Windows Publisher: Apogee Rockets Released: 1996 Media: 3.5 Floppy Model Rocket Sim 4.0 (1996) (3.5" FLOPPY)This program is an ideal design and analysis tool for the rocketry hobbyist. Model Rocket Sim starts out by leading the user through a simple process for describing a rocket. Using a hierarchical "tree-like" diagram, the user builds up a rocket using components from the extensive database of commercial products.This designs with nose cones, body tubes, transitions, fins (elliptical, trapezoidal, and arbitrary shapes), internal tubes, centering rings, couplers, bulkheads, engine blocks, sleeves, arbitrary mass objects, launch lugs, parachutes, and streamers. Each component's material, dimensions, and position within the rocket are specified using a very simple interface. For custom work, this sim allows the user to define new materials, shapes, sizes, and components.As each component is placed into the rocket model, a diagram of the rocket is constructed on screen.Because Model Rocket Sim carefully keeps track of the dimensions of each component, it is able to determine the weight distribution of the rocket design, and hence the rocket's center of gravity (CG). Additionally, components are assigned drag values which are tabulated to arrive at a center of aerodynamic pressure (CP). With CG CP in hand, the system determines the static stability of the rocket. This uses three different approached to calculating CP. It uses the Barrowman equations we're all familiar with, as well as the simplistic "cardboard cutout" method.
