Multiple-nozzle pulse discharge device on a self-propelled base

A method for generating a guidable vortex stream of an atomised mixture of agent discharged as a salvo from the multiple-nozzle pulse discharge device, wherein a range (distance) (L) and area (S) of a spread and effect area of a front of the gas dispersed vortex stream containing microparticles of the active substance generated by the pulse discharge device is shaped by generating a vortex stream by the means of a salvo of a number of similar discharge nozzles located close to each other and varying the number (n) of discharge nozzles participating in a volley, conditioned on a total amount of discharged active substance and total size of the propellant charge used in each salvo remaining constant;

• where a relationship of L and S to the value of n is graphically depicted using a sigmoid curve, where at relatively low values of n, in the range of 1-3, an increase of L and S is relatively small, where at medium values of n, in a range of 4-8, an increase of L and S is largest, and where at larger values of n, an increase of L and S is slowed;
• and where within the range of the values of n occurring in real usage situations, in a range of 1-20, respective minimum and maximum values of L and S differ from each other 4 to 5 times and respective maximum parameters of a device designed based on the method of the invention also differ by just as much from respective parameters of another equivalent pulse discharge device.
