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).
PIPE RESONANCE
The first control line aerobatic models that use the engine capacity of 3.5 — 7 cm3 modelers-athlete transferring from Junior level to senior championship… What it be? Youth as the original sample often chooses superprotein equipment of the world Champions or Europe and tries to copy it. In the absence of speciliaties on the model put serial domestic motor and… due to ignorance of technical and technological methods such copy get poor results and wasting time. The other extreme — a massive increase in checked malakhovich models. So there are “pilotazhki” with mediocre flight characteristics that don’t bring any sporting success.
our Readers probably know of noma abbreviation TX-200. It is the tan called autocritic original design created by the famous in the circles of avtomodelistov Kharkiv V. Taranukha, in collaboration with the candidate of technical Sciences Y. Hajnowski. Creative Union of theory and practice turned out to be quite fruitful. Today we introduce readers to one of the most interesting developments of this magnificent design of the Duo — car railroad layout, created with the extensive use of available and relatively inexpensive units.
