Sky Clear 1: Precipitation Control

Inserting of hygroscopic reagent in clouds with help of rocket system is essentially new technology (wasn't used in industrial scales before). This method based on inputing of the certain quantity of hygroscopic reagent inside a "feeding" area of the cloud, below a level of condensation. The height of reagent imputing is about 1-1.5 km above the ground (for this purpose we produce big rocket system "Sky Clear-5") however, in certain situations, you can use a simple means of small radius of action.

The advantage of this means is:
  • ease of use, the very low price, ecological cleanliness
  • minimum flight altitude ( < 500 meters)
  • minimal amount of pyrotechnic material (110 g)
  • complete absence of explosive substance
  • Jet cartridge "Sky Clean I" is designed for filling powder reactants (approximately 250 g) in the following versions:
    • hygroscopic (stimulation of precipitation from warm clouds)
    • hygroscopic - ice-forming (stimulation of rain and hail prevention)
    • ice-forming (anti-hail works )
Sky Clear I, Jet cartridge
Jet cartridge "Sky Clean I" are started from a container and have characteristics:
  Length of container with reagent, mm.     390  
  Leight of starting container, mm.     580  
  Common length of cartridge, mm.     550  
  Weight, kg.     0.9  
  Calibre, mm     50  
  Maximum altitude, m.     500  
  Mass meteorological reagent, g.       250-350  
  Method of dispersing of reagent    pneumatic  
  Number of active nuclei at 1 cartridge    hygroscopic = 2,50E+14  
  ice-nucleation (-10oC)= 1,50E+15  
  ice-nucleation + hygroscopic = 2,50E+14 + 8,50E+14  
  Time of work of engine, sec.    0.5     Jet cartridge on a test bench
  Start velocity, m./sec.    75  
 depending on the type of reagent
