Young conovici-only pilots rarely taken for the creation of highly complex models. Basically they design a simple and feasible model of universal definition, which are equally suitable for testing of flight control avionics complex, and for competitions. We must remember that half of success on the performances of only pilots — the run-in, reliable motor. More suited KMD-2,5 and MDS-MDS or a 3.5-4 in export performance. It is simple, technological and, most importantly, “volatile” model — is proposed for the attention of young korovikov. Pilotage designed based on the available materials instead of lime for many parts, you can use high quality blanks from aspen, alder or poplar.
Amateur designers sometimes even adulthood may surprise the naive, and young, on the contrary, thoughtful and original solutions. And as an interesting personality, whose signature is a brief article describing the construction.
In the magazine we told about the methods of choosing the parameters of the resonant pipes (“modelist-Konstruktor” No. 9 for 1995) for highly accelerated engines. Fulfilling the wishes of modelers, editors have been asked to continue this theme of the master of sports V. Fontecha from Cherkassy (Ukraine). As you know, at the time of opening of the exhaust window motor is formed as the shock wave represents the process of propagation of a pressure pulse with velocity V=20 sqr(T) (T — exhaust gas temperature in OK).
