Abstract


The main objective of this work was to present the specifi cation of
an experimental fi ring test stand for liquid rocket engines (LRE) and develop
a program for control and acquisition of data. It provides conditions to test
rocket engines with thrust from 50 to 100 kgf. A methodology for laboratory
work implementation using information technology, which will allow the
automatic and remote functioning of the test stand, permits users to input
the necessary data to conduct tests safely, achieve accurate measurements
and obtain reliable results. The control of propellant mass fl ow rates by
pressure regulators and other system valves, as well as the test stand data
acquisition, are carried out automatically through LabVIEW commercial
software. The test stand program is a readable, scalable and maintainable
code. The test stand design and its development represent the state of art of
experimental apparatus in LRE testing.
