-Moving along the orbit many satellites require precise orientation of certain surfaces in the right direction - relative to the Earth, the Sun, stars or some other way. For example, ​to put the camera ​on the ground ​or solar panels ​on the Sun. There are several known approaches for solving this problem.One of them is the use of jet (rocket) orientation engines, which by expending the working body causes the spacecraft to rotate in the desired direction relative to the center of mass. The special ​advantage of this method is the speed and accuracy of the turn. Engine-fans (EF) are analogue of jet engines ​in this case.+When in orbitmany satellites require precise orientation of certain surfaces in the correct ​direction - relative to the Earth, the Sun, stars or some other reference point. For example, the camera ​should be oriented towards ​the ground ​and the solar panels ​should be oriented towards ​the Sun. There are several known approaches for solving this problem. ​For example, you can use jet (rocket) orientation engines, which causes the spacecraft to rotate in the desired direction relative to the center of mass.

 In our model free rotation of the model is possible only around one axis, the vertical one. Therefore, it is recommended to install at least two fan units on the "​satellite",​ which provide turns in the horizontal plane both clockwise and counterclockwise. For maximum efficiency fan units must be maximally separated from each other and from the "​satellite"​ axis of rotation when assembling the spacecraft. In each block there are two fans: one is responsible for rotating the spacecraft clockwise, the second for turning counterclockwise - depending on which sign is indicated in command signal for the whole block. Blocks are controlled programmatically independently of each other. In our model free rotation of the model is possible only around one axis, the vertical one.
