Glider simulator motion platform
During my internship at Stellenbosch university (South Africa) we designed and built a low-cost motion platform for a glider simulator. The simulator was intended for aspiring glider pilots to be able to practice takeoff, aero-tow and landing so they would less training in an actual glider before being able to fly solo.
the platform for this simulator should be capable of simultaneous pitch and roll motion, at angle up to 30 degrees.
In order to achieve the desired angles we used the CV (constant velocity) joint of a car: it was capable of reaching the target angles and was stiff in the yaw direction. Two electromotors were used to power the platform, one per axis. The pyramidal construction of the tube frame was used to bring the center of gravity closer to the center of rotation.
The simulator uses home entertainment flight simulation software (Microsoft Flight Simulator or XPlane). The aircraft accelerations were output to the motion platform through our own washout filter software: the washout filter set the angle of the motion platform that would give the pilot the same sensation as he would feel in the real aircraft.
Boeing737 Simulator
Sim-Industries is a startup company that designs and builds flight simulators for training of airline pilot. For EPST in Maarssen we built a fixed-base Boeing737NG simulator. It has an enclosed cockpit with a curved 180 degree screen for the outside visual, working glass cockpit, MCP, center console and overhead panels and powered control column and elevator trim. I was involved with modeling and implementing the systems functionality and adjustment of the flight model so the aircreft responses match those of the real plane. The simulator has been FNPT2 certified.
Haptic feedback animation for Nissan
The TU Delft has been developing a haptic feedback on the steering wheel of a car for Nissan. This haptic feedback is intended to assist the driver when taking corners or with obstacle avoidance. The animation was made to support a short presentation to Nissan finance department for continued funding. The funding has been received.
The actual animation cannot be shown due to a non-disclosure agreement.
CP-GPS animation
The orientation of any object can be measured with a high accuracy using GPS (Global Positioning System) antennas and the carrier wave signal from the GPS satellites. A new approach to this problem that was developed at the Aerospace Software and Technologies Institute (ASTI).
A presentation was given to several surveying companies. In order to help convey the essence of the new approach without going into too much technical detail, an animation was made. The animation can be found
here.
In the animation the phase of the carrier wave from the GPS satellite to the antennas is shown, together with the relevant geometries. It becomes clear from the animation that, when the number of carrier wave cycles between antennas is unknown, multiple solutions can exist. The intersection point of the circles determines the location of one GPS antenna with respect to the other, resulting in an estimate of the orientation of the object to which the antennas are attached.
