RDSwin allows engineering students to take an aircraft design from first conceptual layout through functional analysis, leading to performance, range, weight, and cost results. By automating the grunt work of vehicle analysis, RDSwin makes enough time for the student to truly learn design. RDSwin integrates Design Layout (CAD), aerodynamics, weights, propulsion (jet & prop), stability & control, sizing, range, performance, and cost analysis. All new, all-original code (even the CAD module), all optimized for aircraft conceptual design and analysis. A true 32-bit Windows Application, with Windows pulldown menus, popup boxes, fonts, graphics, dialog boxes, clipboard read/write, Undo/Redo, and more. RDSwin outputs analysis results and program data to popup boxes, text files, Windows printers, or directly to your spreadsheet, word processor, or internet browser.
