Battle readiness and fighting capacity of military technology of Russian Federation air Force is substantially defined by high tactical and operational characteristics. One of perspective directions of increase of tactical and operational characteristics of military technology is addition of components in hydrocarbonic fuel for the purpose of obtaining fuel mix with a disperse phase on the basis of water as alternative fuel for internal combustion engine. For mixing, homogenization and hashing of fuel mix various devices are used, most effective of which are dynamic devices. The article offers the design of dynamic device combining the functions of the pump, allowing to use it for fuel mix preparation with a disperse phase on the basis of water. Rotary-pulsation device prepares the mixture of various quality - with different diameter of drops of water. For definition of diameter of drops of water in mix it is necessary to define critical speed of movement of drops of water in a stream of at which a process of its crushing is possible. The problem has been solved on the basis of mathematical modeling of a current of two liquid media through working bodies of dynamic device. The mathematical dependence abtained as a result of modeling allows to define theoretical diameter of drops of water in the fuel emulsion, prepared on dynamic device depending on its constructive sizes (width of an aperture, radius of a rotor, length of the modulator, hydraulic resistance of the modulator) and operating modes (time of processing, angular speed of rotation of a rotor, pressure difference for modulator device) of the device. The device under discussion allows to provide additional crushing and hashing of fuel drops emulsion. Thus the size of drops of a disperse phase on the basis of water decreases 10 times that allows several times to lower power expenses per volume of prepared petrol emulsion
