Super-circulation flow around boom thus formed gives rise to additional force directed towards part of main rotor disk with advancing blade. Second fence ensures drawing down point of boundary layer separation and simultaneously separates increased pressure zone arising under action of first fence from negative pressure zone, thus ensuring rise of pressure on tail boom surface on side of retreating blade and increasing on first boom arising under action of first fence. 
     EFFECT: increased lateral force on tail boom and creating of compensation part of reactive torque at hovering and low speeds.

Abstract: FIELD: inorganic synthesis. 
     SUBSTANCE: invention relates to preparation of salts of transition metals with organic acids, in particular to formic acid ferric salt. Method is accomplished in bead mill provided with mechanical blade-type stirrer in aqueous formic acid solution (5-10 mole/kg). Iron is used in the form of steel sidewall across the height of reactor and also as particles of reduced iron stirred with stirrer together with glass beads, and/or as broken steel cuttings, and/or yet as split cast iron in any weight proportions. Method is accomplished by continuously introducing 10-20% hydrogen peroxide solution at a rate of 0.015-0,030 mole peroxide/min per 1 kg liquid phase (salt slurry) in presence of stimulating additive, in particular iodine, bromine, alkali metal or ferrous iodides or bromides in amounts (on conversion to halogens) 0.1-0.15 vole per 1 kg reaction mixture. When 1,2-1,5 mole/kg of ferrous salt is accumulated in reaction mixture, stirring and addition of hydrogen peroxide solution are stopped, product slurry is separated from unreacted iron and/or its alloys as well as from glass beads and filtered. Filtrate is recycled into process and precipitate is recrystallized from saturated iron formate solution of aqueous formic acid solution (1-2 mole/kg). 
     EFFECT: simplified finished product isolation stage, reduced total process time, and reduced power consumption.

При этом проекции этих границ на ось симметрии профиля во всех точках совпадают с проекциями туда же границ профиля ступенчатого трансформатора, уравнениями линий потока, в поле волнового вектора которого они описываются. Таким образом, длина трансформатора равна длине ступенчатого трансформатора, то есть минимальна. 5 ил., 1 табл.
