Brazilian Space Agency rocket engine test vai national
Filed Under (Space) by admin on 11-08-2008
The president of the Brazilian Space Agency (AEB), Carlos Ganem, explains how the test will be the engine of the new national satellite launch vehicle (VLS), which means the resumption of the project of developing a Brazilian rocket.
The Brazilian Space Agency (AEB) vai test this week, on August 6, in Sao Jose dos Campos, the engine of development in Brazilian rocket to launch satellites, known as the VLS-1B.
In preparation for the resumption of the project, the agency maintains technical measures have been taken to strengthen safety. The concern of AEB is to prevent accidents such as occurred in 2003, at the base of Alcantara (MA), when 21 technicians of the Brazilian Space Program died during tests, started the engine in the explosion of a rocket, on the eve of the launch.
Test bench
“It will be a test bench, which makes no movement, not to be a simulation of the shot that engine. It will allow us to check how many go with the improvements seen the future launch of the rocket on a real, which must be given in 2012. Several security requirements were explored in order to achieve better performance and an upgrade of the technical scope of the project, “said the president of the United States Agency AEB, Carlos Ganem.
In overseeing the technical adequacy is the coordinator of vehicles launched from the AEB, Ulysses Côrtes Oliveira. He said the design of the VLS-1B passes through a “critical review” of all its major components.
Thermal protection
“The part of thermal protection will be tested. Another change was the increase in empty space for the expansion of gases and the most significant change in the ignition system, mechanical device security, which keeps the energy transferred by circuits so unwanted,” Oliveira explained.
All the operational cost which involves the test of the engine is estimated at $ 1 million. According to the president of AEB, a figure consistent with the target pursued by the technological project of the launcher of satellites.
Costs compatible with the benefits
“The numbers in a space programme surprised by the magnitude, but also surprising are the benefits that generates for the whole of Brazilian society. There is no telecommunications programs that can not support a satellite, you do not convincing tracking air traffic without satellites There is no diplomatic communications with government and security without satellites, “argued Ganem.
The schedule of the government provides two laçamentos trial before the full and official forecast for 2012. In 2010 it launched a first version of the VLS-1B without charge, partly supplied, and the following year a second version, with tanks full. “It is an important step to test, in addition to engines, the whole geometry of the network and electrical towers,” stressed the coordinator Oliveira.
