Last tests for launching a UNal rocket
A strength test and a communications test will provide the necessary information for launching a Universidad Nacional de Colombia (UNal) Aerospace Research and Development Group (GIDA, for its Spanish acronym) rocket.Bogotá D. C., 03 de agosto de 2016 — Agencia de Noticias UN-
One of the tests is for telemetry which will provide information on communication between land and the rocket.
The telemetry system test which will take place at the Neusa water reservoir will assess the effectiveness of the communications, in other words, verify if data is correctly communicated to the electronic land-based system, explained Óscar Iván Ojeda, Mechanical Engineering student and GIDA Coordinator.
“This test has risks. We are trying to carry out the test so we can have a line of sight of approximately tree kilometres high (1.8 miles),” he said.
The second test which will be carried out is propulsion which basically consists of measuring the force or thrust of the motor. For this they will use four different size motors but whose geometry is practically the same.
Motors are not going to fly as this is a static test. They will be fixed to the ground and measure the thrust through time with different kinds of equipment. “This will provide information to verify how standardizable the rocket can be,” said Ojeda.
This test as with all of these types of assessments will be held at the facilities of the Colombian Military Industry (INDUMIL, for its Spanish acronym) explosives factory.
“The adjustments will be ready for the launching at the end of October. There are already four educational institutions interested in participating with a useful payload of the rocket,” said Ojeda. Ricaurte School in Fusagasugá, the Abraham Lincoln School and UNal IPARM School are already working on this project.
Meanwhile the UNal Planetary Sciences Group wants to perform a test with extremophile bacteria (organisms that thrive in physically or geochemically extreme conditions) to become cognizant of some behaviorial patterns in these acceleration conditions.
They have already carried out launching and trajectory modelling (simulations) and hope the motors will produce the necessary propulsion so the trajectory will be as close as possible to the simulation.
“We need certain thrust to climb the 2.5 kms (1.5 miles) we want. If it is too far from the real curve we would have to assess if we need to change to motor or other variables related to the rocket, but we are confident regarding its behavior,” they added.
Ojeda invited students to become part of an introductory course on aerospace engineering directed to freshmen and sophomore students of any faculty.
Another invitation is for engineering students who want to become part of the group. They will publish the terms of reference on their Facebook account soon to provide the necessary profiles. There will summon approximately 10 people.(Por: Fin/HEVC/MLA
