Abstract: Abstract For many years, theory of similarity has been used either in aware or unaware manner in many branches of science. It turns out that it is impossible to realize the examining real phenomena and processes, or objects due to their complexity and costs. For example, the examining water flow in rivers or behaviour of manned and unmanned flying objects during the flight. In such cases, one usually builds a smaller object (or larger) in such a way that one could carry out measurements in labs by means of modern apparatus. The obtained results should be reliable, i.e. there should exist the possibility of either direct or indirect transition to the real object.
