RTDynamics, a leading rotorcraft simulation company, has announced that it has released the 1.2 update for its helicopter flight dynamics simulation package, RotorLib.
The update includes major improvements to the flight dynamics model fidelity and the C++ API. RotorLib customers can immediately upgrade to the new version for free and use the enhanced flight dynamics models.
Rotorlib itself is a C++ programming library containing a physically based helicopter dynamics simulation model and an easy to use high-level control layer, which fills the gap between helicopter dynamics and the AI code. RotorLib applications include visual simulation and training, helicopter simulators, tactical trainer systems and “serious games”.
Version 1.2 introduces a new rotor dynamics model capable of better hover and hover to forward flight transitions as well as improved handling of general flight maneuvers. The ground contact model of RotorLib has also received a major realism upgrade. The new model is more general and allows skid and wheel parameters to be changed easily.
Another improvement is the new Updater class which solves the previous simulation step time problems. The Updater class manages the step time in real time simulations where the step time varies continuously. Tests show major stability improvements especially when ground contacts happen.
Numerious other additions like DLL interface examples, new waypoint (and route) following classes and optimizations are also included within the latest version of RotorLib.
