FIELD: agriculture, in particular, irrigation equipment. SUBSTANCE: air irrigation system has aerostatic aircraft having surface directed to Sun and covered with solar energy absorbers. Solar energy is directed through cable to solar batteries suspended to aircraft from bellow. Solar batteries are connected with heating and refrigerating units positioned within aircraft in contact with gas. Heating unit is switched on to to heat gas and, consequently, increase lifting force, and is switched off to maintain lifting force at constant level. Refrigerating unit is switched on to reduce gas temperature and, consequently, aircraft lifting force. As a result irrigation system advancement speed is reduced along irrigation trace. EFFECT: increased efficiency by increasing or reducing gas temperature and, consequently, aircraft lifting force and provision for ecologically clean irrigation system. 4 dwg |
