Claims (4)

1.      Устройство для турбулизации и ускорения фронта пламени, включающее корпус с набором препятствий-турбулизаторов и источник зажигания, отличающееся тем, что набор препятствий-турбулизаторов выполнен в виде перфорированных пластин толщиной не менее 1 мм, установленных в плоскостях поперечных сечений корпуса, с шагом, позволяющим установить не менее 2 пластин, а корпус на выходе заканчивается соплом.1. A device for turbulization and acceleration of the flame front, comprising a housing with a set of obstacles-turbulators and an ignition source, characterized in that the set of obstacles-turbulators is made in the form of perforated plates with a thickness of at least 1 mm installed in the planes of the cross sections of the housing, in increments of allowing to install at least 2 plates, and the housing at the outlet ends with a nozzle. 2.      Устройство по п.1, отличающееся тем, что отверстия в перфорированных пластинах имеют острые кромки и в соседних пластинах смещены относительно друг друга.2. The device according to claim 1, characterized in that the holes in the perforated plates have sharp edges and are displaced relative to each other in adjacent plates. 3.      Устройство по п.1 или 2, отличающееся тем, что размер отверстий во всех перфорированных пластинах остается постоянным или изменяется по мере удаления от источника зажигания, при этом в первой пластине диаметр отверстий превышает максимальный гасящий размер отверстий. 3. The device according to claim 1 or 2, characterized in that the size of the holes in all the perforated plates remains constant or changes as you move away from the ignition source, while in the first plate the diameter of the holes exceeds the maximum blanking size of the holes. 4.      Устройство по п.1, отличающееся тем, что сопло выполнено дозвуковым или сверхзвуковым. 4. The device according to claim 1, characterized in that the nozzle is made subsonic or supersonic.
