As is known, highest content the silver compounds (AgJ and similar) in products of burning and therefore high activity of pyrotechnic mixture, reaches by burning this mixture under high pressure. It's most successfully realized through burning pyrotechnic mixture in a mode of the mid-flight engine. In this case it is possible to find a working pressure that would be optimal for output of ice-nucleation aerosol. The rockets with use of ice-nucleation solid propellant are known and applied all over world. However uniqueness of production of the company consists in use of IHF with very high content of ice-nucleation composition in its structure, without degradation of ballistic characteristics of the fuel. It results in very high output of ice-nucleation aerosol in combination with rather small amount of silver compounds in IHF.

We have developed the "know-how" of dual-mode engines (first mode is starting, without ice-nucleation composition in structure of a fuel; the second mode is mid-flight). There is an opportunity to adjust parameters of modes in any range, which is necessary for the customer. Rocket "Sky Clear-6" produced by our company has the following characteristics. In a rocket "Sky Clear-6" used different silver compounds. For comparison they were recalculated on AgJ.

 In a rocket "Sky Clear-6" uses other silver compounds. For comparison we the recalculated this on AgJ.
Now our company starts development of a product "Sky Clear-7" with the contents of silver compounds in recalculation on AgJ about 2 % and common ice-nucleation activity approximately 1.2E+16 per rocket.
