FUEL-HEATING UNITS FOR AIRCRAFT TEST STANDS
Abstract
Object of the invention: A unit for preheating fuel in aircraft test stands, which includes in itself a preheater of the liquid heat carrier with electrical heaters and a pump as well as a preheater of the fuel with coil-pipe heat exchangers, joined by tube connections which has the distinguishing feature that for the purpose of shortening the time and expenditure of electrical energy for heating the heat carrier and the fuel, and also for simplifying the design and operation of the unit, it in the preheater of the heat carrier is constructed in the form of two coaxial vertically disposed cylinders, provided with electrical heaters while at the same time in the cavity of the lesser cylinder there is mounted a pump joined by a vertical shaft with a two-speed electrical motor which assures the circulation of the heat carrier through the pipe coils of the preheater of the fuel or the controllable crossover connection in the heating up of the heat carrier.
