Predecessors to OpenVSP including VSP [1] and Rapid Aircraft Modeler (RAM) were developed by J.R. Gloudemans and others [2] for NASA beginning in the early 1990s. [3] OpenVSP v2.0 was released as open source under the NOSA license in January 2012.
Trim drag, denoted as Dm in the diagram, is the component of aerodynamic drag on an aircraft created by the flight control surfaces, [1] mainly elevators and trimable horizontal stabilizers, when they are used to offset changes in pitching moment and centre of gravity during flight.
The drag curve or drag polar is the relationship between the drag on an aircraft and other variables, such as lift, the coefficient of lift, angle-of-attack or speed. It may be described by an equation or displayed as a graph (sometimes called a "polar plot"). [1] Drag may be expressed as actual drag or the coefficient of drag.

English: Drag curves for an aircraft with a given weight in flight. The parasitic drag increases with the square of flight velocity; The lift-induced drag decreases with the square of velocity. As a result, the total drag (the sum of both components) typically has a minimum value.
Simulation of an airplane using Open VOGEL, an open source framework for aerodynamic simulations based in the UVLM. The Vortex lattice method, (VLM), is a numerical method used in computational fluid dynamics, mainly in the early stages of aircraft design and in aerodynamic education at university level.
Since most avionics manufacturers see software as a way to add value without adding weight, the importance of embedded software in avionic systems is increasing. Most modern commercial aircraft with auto-pilots use flight computers and so called flight management systems (FMS) that can fly the aircraft without the pilot's active intervention ...
