The MathWorks, Natick, MA, has released Aerospace Toolbox, which provides reference standards, environmental models, support for importing aerodynamic coefficients, and three-dimensional visualization capabilities in MATLAB®. With a built-in interface to the FlightGear flight simulator, the new toolbox lets engineers visualize flight data in a 3D environment and reconstruct behavioral anomalies in flight-test results.

The software includes utilities for unit conversions, coordinate transformations, and quaternion math, along with standards-based environmental models for the atmosphere, gravity, and magnetic fields. Flight parameter utilities calculate such common parameters as equivalent airspeed, Mach number, and dynamic pressure.

Engineers can import aerodynamic coefficients from the U.S. Air Force Digital Data Compendium (Datcom) into MATLAB to carry out preliminary control design and vehicle performance analysis. Using the coefficients with Aerospace Blockset, available separately, engineers can calculate aerodynamic forces and moments for Simulink flight simulations.
