Tank draining, etc. For example, draining the day of a tank during a “flight” enterprise takes more than a dozen hours, while the main time costs are associated with the opening of leaks.
Since there are broad plans in Russia to quantify annual rockets, the growing need for new tank drying methods is becoming increasingly important. It was decided to take up this task at the Omsk Polytechnic University (OmSTU) – it has developed a promising drying technology based on the use of vacuum, laser, and ultrasound.
Liquid filling of metal plate cavityAs a result of the studies conducted by the university, it was found that the use of pulsed laser radiation can be realized by a 28 percent reduction in energy costs in checking the continuous operation of the laser.
In addition, the constant operation of the laser seriously increases the pressure of the initial vapors and delays emissions, while this effect is not observed during periodic (pulsed) operation of the laser.
A metal plate was taken as an experimental sample, imitating a part of an Angara-class bakarakette carrier, and experiments are currently being carried out on plates, unique microchannels, in the future it is planned to conduct studies on full-fledged tank models. racket.
