FUEL-HEATING UNITS FOR AIRCRAFT TEST STANDS

摘要

The proposed unit, as compared with the known ones, has a simplified design in its construction, is more convenient in operation, and more reliably assures a constant temperature of the heated fuel in the process of tests of the fuel aggregate. For this purpose the preheater of the carrier is designed in the form of two coaxial vertically disposed cylinders filled with heat carrier and provided with electrical heaters, the lesser cylinder having installed in it a pump jointed "by a vertical shaft with a two-speed electrical motor mounted on the flange of the cylinder.
