The paper describes the results of the field experiment on studying solar radiation transmission in the visible wavelength range through model aerosol media formed in the lower troposphere with the help of generators installed aboard helicopters. The refractive index and the average size of the aerosol particles formed are close to those characteristic of the natural stratospheric aerosol. The composition of the equipment complex used to control aerosol optical and microphysical aerosol parameters is considered. The measurement results are in satisfactory agreement with the results of theoretical and experimental studies in simulation chambers.

The production of parts of the required quality from carbon-graphite impregnated with copper based alloys without the use of autoclaves is considered. Data on the effect of some alloying elements and inoculators on the interfacial interaction between carbon-graphite and copper alloys are presented. The structure and properties of the produced composites are studied.
