ServoFlight: pneumatically actuated full flight simulator

One of the most important components of an aircraft ground testing infrastructure is hardware and software test benches with complete or partial imitation of the aircraft in complex, on-board electronic equipment and controls. The development and debugging of such complexes is a complicated problem. The solution for this problem is presented in in the form of the automatic test complex for unmanned aerial vehicle engines and propulsion devices mounted on the Gough–Stewart platform manipulator. The complex is based on the modular measuring platform and also includes a set of various sensitive elements for forces, vibration, speed, torque, video and sound registration. The article also describes the procedure for one of the functional assessment stages of the U AV engine test complex, notably, the assessment of the tensometric measurement accuracy. Further development of the complex associated with the software implementation of atmosphere, wind turbulence models and modules for preliminary formation of test scenarios-UAV flight paths.

To make motion perception more realistic, a current-implemented classical washout motion cueing algorithm (CWMCA) is extended to a model predictive motion cueing algorithm (MPMCA) for a seven-cylinder pneumatically actuated Stewart platform. Through this enhancement, not only are potential predictive signals taken into account, but also comprehensive information and data sets relating to the mechanical limitations of the simulator platform. The significantly increased information content enables the calculation of far more specific targeted requirements for the platform. First, the platform kinematics are derived and its physical platform constraints are examined. Furthermore, the CWMCA is extended and transformed into a state space-based motion cueing algorithm for the purpose of setting up a linear quadratic MPMCA. Finally, the MPMCA is simulated and evaluated with respect to its degree of realism.
