Using a hierarchical \"tree-like\" diagram, the user builds up a rocket using components from the extensive database of commercial products.\u003cbr\u003eThis 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.\u003cbr\u003e\u003cbr\u003eAs each component is placed into the rocket model, a diagram of the rocket is constructed on screen.\u003cbr\u003e\u003cbr\u003eBecause \u003cbr\u003eModel 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. \u003cbr\u003e\u003cbr\u003eFor Windows (32-bit Systems) [*Please review compatibility\/platform sections in 'What You Get']\u003cbr\u003e\u003cbr\u003e","brand":"Apogee Rockets","offers":[{"title":"New In Pamphlet","offer_id":46931367723286,"sku":"2548","price":42.48,"currency_code":"USD","in_stock":false},{"title":"Used In Pamphlet","offer_id":46931367756054,"sku":"91939","price":42.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0083\/0377\/1710\/products\/2023822923652.jpg?v=1700615572","url":"https:\/\/www.neverdiemedia.com\/products\/rocksim-4-0","provider":"NeverDieMedia","version":"1.0","type":"link"}
