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.
