Abstract :
Engine test bed is a tool used for testing in the development of new aircraft
engines when installed into aircraft to determine the capabilities of each engine.
This engine test bed manufacturing aims to meet the needs of the learning process
in supporting practical activities. By determining the geometry, modeling,
material selection, manufacture, and testing of the engine test bed, it will know the
good engine performance before use.
The manufacturing method used to manufacture the engine test bed uses
cutting, drilling, welding and threaded fasteners. And using practical and
analytical methods to get test data validation.
The manufacturing process for this engine test bed starts with the
manufacture of the main structure consisting of the manufacture of a test table,
load cell holder, sliding rail, manufacture of engine mounting, manufacture of
protection structure and ends with assembly. Furthermore, in this study, the
preparation of the test was carried out by collecting data, the results of the engine
test obtained were then validated by comparing the value of the static thrust
calculator and the test data of the test equipment that had been carried out, then
looking for the value of the fuel consumption used. The measured thrust results
were compared with the static thrust calculator values obtained by an average
difference. From the results of the comparison of errors on the test equipment, the
22×8 propeller (4.5cm chord) obtained an average error of 4.178%. While the
propeller 22×8 (chord 5cm) the error generated is 3.719% and from the value of
fuel consumption obtained it produces 588,600-20,708 (N/kW.hr) this shows a
good level of decline, so the engine used is more efficient in use. From the test
results, it can be said that the engine test bed has accuracy and can produce good
engine performance
