Abstract
This study investigates the forces exerted on a fluid spraying system in a drone through experimental tests. In this system, water is pumped from the ground to the high altitudes. Due to the importance of accurate estimation before design and implementation in real conditions, the effects of changing each of the sub-systems have been tested on both ground and low altitudes. The study of these forces, range, flow and pressure of the fluid in this system requires testing in different hoses and nozzles. In this article, two types of hoses with diameters of ¾ in and 1 in and nozzle with diameter of 9 mm have been studied. Also, the effect of different heights of the system (7 and 11 meters) and different angles of the nozzle have been investigated. The results of this test led to the development of equations essential for calculating the flow rate, pressure and range of the spraying fluid at any desired height to restrain the reaction force of the nozzle. The result of this research can be used in the design and optimization of high-altitude fluid spraying systems. In this article, the height of 20 meters as a desired height for designing the system is examined due to the achieved formulas and its results are presented.
