* An Open Source, Object-Oriented, Cross-Platform Flight Dynamics Model in C++
|
||||||
|
|
||||||
|
* \section intro Introduction
|
||||||
|
*
|
||||||
|
* JSBSim is an open source, multi-platform, object-oriented flight dynamics
|
||||||
|
* model (FDM) framework written in the C++ programming language. It is
|
||||||
|
* designed to support simulation modeling of any aerospace craft without the
|
||||||
|
* need for specific compiled and linked program code, instead relying on a
|
||||||
|
* versatile and powerful specification written in an XML format. The format is
|
||||||
|
* formally known as JSBSim-ML (JSBSim Markup Language).
|
||||||
|
*
|
||||||
|
* JSBSim (www.jsbsim.org) was created initially for the open source FlightGear
|
||||||
|
* flight simulator (www.flightgear.org). JSBSim maintains the ability to run
|
||||||
|
* as a standalone executable in soft real-time, or batch mode. This is useful
|
||||||
|
* for running tests or sets of tests automatically using the internal scripting
|
||||||
|
* capability.
|
||||||
|
*
|
||||||
|
* JSBSim does not model specific aircraft in program code. The aircraft itself
|
||||||
|
* is defined in a file written in an XML-based format
|
||||||
|
* where the aircraft mass and geometric properties are specified. Additional
|
||||||
|
* statements define such characteristics as:
|
||||||
|
*
|
||||||
|
* - Landing gear location and properties.
|
||||||
|
* - Pilot eyepoint
|
||||||
|
* - Additional point masses (passengers, cargo, etc.)
|
||||||
|
* - Propulsion system (engines, fuel tanks, and "thrusters")
|
||||||
|
* - Flight control system
|
||||||
|
* - Autopilot
|
||||||
|
* - Aerodynamic stability derivatives and coefficients
|
||||||
|
*
|
||||||
|
* The configuration file format is set up to be easily comprehensible, for
|
||||||
|
* instance featuring textbook-like coefficients, which enables newcomers to
|
||||||
|
* become immediately fluent in describing vehicles, and requiring only prior
|
||||||
|
* basic theoretical aero knowledge.
|
||||||
|
*
|
||||||
|
* One of the more unique features of JSBSim is its method of modeling aircraft
|
||||||
|
* systems such as a flight control system, autopilot, electrical, etc.
|
||||||
|
* These are modeled by assembling strings of components that represent filters,
|
||||||
|
* switches, summers, gains, sensors, and so on.
|
||||||
|
*
|
||||||
|
* Another unique feature is displayed in the use of "properties". Properties
|
||||||
|
* essentially expose chosen variables as nodes in a tree, in a directory-like
|
||||||
|
* hierarchy. This approach facilitates plugging in different FDMs (Flight Dynamics
|
||||||
|
* Model) into FlightGear, but it also is a fundamental tool in allowing a wide
|
||||||
|
* range of aircraft to be modeled, each having its own unique control system,
|
||||||
|
* aerosurfaces, and flight deck instrument panel. The use of properties allows
|
||||||
|
* all these items for a craft to be modeled and integrated without the need for
|
||||||
|
* specific and unique program source code.
|
||||||
|
*
|
||||||
|
* The equations of motion are modeled essentially as they are presented in
|
||||||
|
* aerospace textbooks for the benefit of student users, but quaternions are
|
||||||
|
* used to track orientation, avoiding "gimbal lock". JSBSim can model the
|
||||||
|
* atmospheric flight of an aircraft, or the motion of a spacecraft in orbit.
|
||||||
|
* Coriolis and centripetal accelerations are incorporated into the EOM.
|
||||||
|
*
|
||||||
|
* JSBSim can output (log) data in a configurable way. Sets of data that are
|
||||||
|
* logically related can be selected to be output at a chosen rate, and
|
||||||
|
* individual properties can be selected for output. The output can be streamed
|
||||||
|
* to the console, and/or to a file (or files), and/or can be transmitted through a
|
||||||
|
* socket or sockets, or any combination of the aforementioned methods.
|
||||||
|
*
|
||||||
|
* JSBSim has been used in a variety of ways:
|
||||||
|
*
|
||||||
|
* - For developing control laws for a sounding rocket
|
||||||
|
* - For crafting an aircraft autopilot as part of a thesis project
|
||||||
|
* - As a flight model for FlightGear
|
||||||
|
* - As an FDM that drives motion base simulators for some
|
||||||
|
* commercial/entertainment simulators
|
||||||
|
*
|
||||||
|
* \section Supported Platforms:
|
||||||
|
* JSBSim has been built on the following platforms:
|
||||||
|
*
|
||||||
|
* - Linux (x86)
|
||||||
|
* - Windows (MSVC, Cygwin, Mingwin)
|
||||||
|
* - SGI (native compilers)
|
||||||
|
* - Mac OS X
|
||||||
|
* - FreeBSD
|
||||||
|
*
|
||||||
|
* \section depends Dependencies
|
||||||
|
*
|
||||||
|
* JSBSim has no external dependencies at present. No code is autogenerated.
|
||||||
|
*
|
||||||
