World of models

Very often the students see on television or in a magazine, the launch of the spacecraft, have a vital interest in how this happens. If I could build such a rocket! And-models are very close to real rockets: same shape, only the size is much smaller.

-Models of missiles play a big role in aerospace education of youth. In the process of working on them, “the rocketeer” learn to read, match and draw up the technical documentation, get acquainted with history of creation and development of space-rocket techniques, study design missiles. At the same time, the process of learning the fundamentals of designing and manufacturing of individual components and the whole model. In this creative process, develop skills of solving technical problems, chief of which is the creation of a flying copy of the rocket.

In this post we will talk about the design of foam electrics.

In recent years modelers have gained access to great material to create flying models. This is a finishing foam ceiling panel with dimensions of 500×500 mm with a thickness of from 3 to 6 mm. a Large part of such panels from the front side is decorated with various raised patterns, but the market fall and the leaves with a smooth surface — that they should be given preference. From these panels, you can produce almost all the main parts of the model from the wing spars and ribs to of the fuselage frames and plating. By the way, if you could purchase a plate of 6 mm thickness, it is easy to do a 3-mm plate, spreading the workpiece on two 3-mm with a glow current of nichrome wire.

Parameters and characteristics of the model correspond to the categories Ѕ8А and Ѕ8В. The diameter of the container under the engine selected in accordance with a cross-section of the sleeve (MRD-2,5-3-3 or MRD-5-3-3). We present several design and technological recommendations for the production model.
