The propeller and view of the aircraft model

  The propeller is a power of changing engine into the tension apparatus. Propeller efficiency will affect to the model aircraft flying achievements directly.There is no doubt that it is very important in the aircraft competition.just like the sales to the online shop .It is very similar to the works of the propeller blades and wing. If the blade is taken down to observe, you will find that it is a distorted view of the wing. The blade section and wing profile are almost the same. The blades and wings difference is that the movement of the wings in the air is substantially flat movable and the blades round the propeller shaft rotation, and forward with the aircraft one thousand. Propeller Rally is generated by the paddle movement in the air. Due to the blade have both the rotational movement and the forward movement, the stream blowing blades comprises two parts: the part of the airflow from the side perpendicular vertical to the propeller shaft, and another portion of the airflow that is front parallel to the propeller shaft.

  A aircraft model in a horizontal state, placed in the middle of three mutually perpendicular planes, and make one of the longitudinal axis perpendicular to the plane body, and in parallel with the other two planes. If we see the model aircraft from three directions at a sufficiently far place, and to painting shape that we saw on each plane, that is, to make the projection of the model aircraft in a three mutually perpendicular plane, and then develop these three perpendicular flat, you can get the picture - top view, side view and front view. Under normal circumstances, these three views can be comparatively expressed the shape and the main dimensions of a model airplane.

  When actually drawing the model aircraft drawings, in order to save the drawings, three position is in a more compact side. But no matter how placed, we must develop the ability of imagining a complete three-dimensional model airplanes in accordance with the principles of the three-view.it is very important to make a good aircrafts. by the way, the engine is very important, many people use the gasoline engine for their aircraft model, it is a good choice, why not?
