Abstract :
The propulsion system is the driving system of each aircraft, the air as a
working fluid is correlated by the system, and the reaction of this acceleration or
acceleration produces a force on a system called thrust. As with the actual
aircraft, the selection of an improper propulsion system will result in the aircraft
not being able to fly perfectly, because the thrust of the aircraft does not work
optimally and increases the chance of an aircraft accident. Therefore we need an
electric-based unmanned propulsion system test equipment to choose the right
propulsion system.
The method used in the thesis is practice and analytics to obtain validation
and determination of dimensions in the propulsion test equipment that will be
assembled with the stages of selecting test propellers and making and testing of
the test equipment.
To validate the electric-based unmanned aircraft propulsion test
equipment by comparing the manufacturer's data and test equipment data with the
tests that have been carried out. 14x7 and 12x6 propellers are tested under the
same environmental conditions and with rotational speeds ranging from 1000-
8000 rpm. Thrust is measured or compared with the manufacturer data and the
average difference obtained from the two results is a maximum of 9,474% and a
minimum of 2,093%. In this 14x7 propeller, an average error of 5,170% was
obtained while in the 12x6 propeller an error was generated 5,570%. From the
average error produced it can be said that the test equipment has good accuracy.
