Aircraft generators of fine ice particles on liquid nitrogen «GMCHL-A».

  The GMCHL-A generator provides a maximum reagent flow rate of 30 g/s with a refilled mass of liquid nitrogen of 96 kg, power consumption at a supply voltage of 27 V is not more than 162 W. Realizing the need for nitrogen generators during large-scale work to improve weather conditions in megacities, on the initiative and at the expense of the ATTECH Agency, more than 10 quick-detachable nitrogen generators were manufactured, which were equipped with aircraft of various types (An-12, Il-18, An-72, An -26, An-30, An-28, M-101T «Gzhel»). Installation of the GMCHL-A generator on board an aircraft (helicopter, plane) does not require special design modifications. The design of the generator allows the installation of a pylon with a nozzle on technological hatches or on a porthole plug. On fig. Figure 1 shows an aircraft nitrogen generator on the An-12 aircraft, and Figure 2 shows its general view.

Rice. 2. General view of GMCHL-A

  If necessary, to ensure the operation of the GMCHL-A generator during the entire flight, an additional number of Dewar vessels with nitrogen of the SK-40 type are loaded on board the aircraft. Aircraft nitrogen generators can be installed on aircraft with both pressurized and non-pressurized cabins.

  An important argument in favor of the use of nitrogen generators in production work on active exposure is that the cost of exposure to clouds using liquid nitrogen is significantly lower than the cost of exposure to granular carbon dioxide.

  The experience of work on the active influence on supercooled clouds confirmed the expediency of using liquid nitrogen aircraft generators.
