Santos Dumont Program

The year is 2005 and The Santos Dumont sounding rocket program begins, a program to develop large aluminum hybrid rockets capable of reaching altitudes as high as 8 km an possessing computer controlled telemetry and parachute recovery systems. The program was divided in to two stages the development of the SD-1 and the SD-2, the first one being a 500N rocket and the second one a 1500N rocket. Not only the rockets were developed, a test bench apparatus was constructed to test the rocket’s motors before launch. The SD-1 motor was constructed and tested several times with everything set the 2 launches were successively done and the development of the SD-2 could begin.

In 2006 the tests in the SD-2 class motor had began and the motor was fired more than 30 times in horizontal and vertical positions. In 2008 group of students from The Hybrid team went to São José dos compos with the mission to validate aerodynamic profile of the SD-2 rocket in the Brazilian Aeronautics and Space Institute. Several improvements were made in the rocket with the knowledge gained in this short period. The improved SD-2b motor is currently under qualification tests and the first launch will occur soon after.
