Airborne aerosol complex SAG-26KS (Fig. 1) is a fundamentally new launcher with reusable barrels for caseless pyrotechnic active elements «Rain-S» and «Rain-K», while the elements «Rain-S» are designed for horizontal seeding clouds along the flight path of the aircraft, and the Dozhd-K elements carry out vertical seeding of clouds similar to PV-26 aircraft squibs. The barrels are quick-detachable elements and can be interchanged.

The technical characteristics of the active elements «Rain-S» and «Rain-K» are similar to the corresponding characteristics of the SAG-26 generators or PV-26-01 squibs. The difference from the latter lies in their design — in the absence of metal cases, the functions of which in the SAG-26KS complex are performed by reusable barrels, which ensures a significant reduction in the cost of consumable elements.
Technical characteristics of the active elements «Rain-S» and «Rain-K»
|Characteristic||Active element “Rain-S”||Active element “Rain-K”|
|Caliber (diameter), mm||20,0||24,5|
|Working time, s||360||40|
|Weight of pyrotechnic composition, g||150||70|
|Yield of ice-forming aerosol at -10°C, 1/g||1,5*1015||3,4*1014|
The launch of the active elements «Rain-S» and «Rain-K» in the SAG-26KS complex is provided using a remote control. The control panel (Fig. 2) in automatic mode ensures the operation of 1 to 12 cassettes (beams), each of which is equipped with 32 active elements, that is, it allows you to initiate the launch of up to 384 active elements. The control panel is designed to work with both SAG-26KS and SAG-26V aircraft aerosol systems. The remote control is located in the cockpit and allows the operator to launch singly and in series.

The use of these complexes with the use of «sleeveless» active elements equipped in cassettes with reusable barrels will make it possible to seed clouds with ice-forming aerosol both at the top and under the base of the cloud at a lower cost.
