Paraglider simulator DemoFly 4.0 – February 2008

The next, fourth version of simulator updated at 80%. Change concerned all aspect of the program. Greatly extended and are added new functions flight dynamic of paraplane, aerologic and indicator. Briefly about changes and novation:

- Optimized mode of play with wing on the land. Now possible not only stand, but also fast running before take off.

- The wing became more realistic in condition of the turbulences. Asymmetrics, frontal collapse, back collapse and transition between them and normal flight look the more realistic.

- Added indication of the overloading (the effect of the darkening in eyes).

- Removed glitches of the strange flight with impossible altitude.

- The big territory over 600 square kilometers with flat area and maintained terrain. Photorealistic panoramas due to Google maps. The one part of Honolulu Island was selected for the main prototype of terrain.

- Absolutely new model of aerologic of ground winds. Dynamically calculating zones of dynamic in depend of power and directions of winds, relief of terrain. Theoretically possible load any relief and get more realistic picture. The algorithm which used in simulator similar methods calculation of aerodynamics of resistance cars and flying machines. Winds are transformed both on vertically and on horizontally (effects of the reinforcement of wind on top of hills and weakening where it is necessary).

- Completely modernized dynamic model of thermal in average and upper zone of flow. Also added gradient crater of horizontal winds.

- Clearly simulated effect of weakening before and reinforcements after passage thermal flow of horizontal winds. The bases of thermal and processes inside it looks more naturally. Now these thermal always end by the cloud and mainly with leeward sides.

- Firstly added thermo-dynamic model of thermal flows of lower level “bubbles”. Now, warming of surface depends on the azimuth and angle of the sun lights. Warmed air bubbles leave with trigger where it must leave. The particularity: model start to work in 10 minutes after start of simulator - this time required for installing the thermodynamic balance and warming surfaces. These thermals do not get to the bases of clouds: or weaken, or dissolve by the more powerful thermals at average level. Lower level flows have a gradient crater of horizontal winds like as average level thermals.

- The comfortable user interface allows changing practically all parameters of aerologic of simulator without close program: azimuth and angel of the sun place (thermal activity), azimuth and power of winds, diameter of the thermal flow and altitude of the cloud base. Also it possible to change parameters of the wing (old-new) and etc.

- On number of requests added GPS which automatically record track of the flight in format of OZI_EXPLORER!!! And maps for it. Why invent the bicycle - OZI - a good analyzer of the flight.

- As before, the simulator is free download but now need to free register it. Unregistered version working will close in 10 mines after start. This is for following possible commercial project.
