New LILE, new name: Atauúba

January 10, 2012 Comments off

The Hybrid Team has elected a new name for their most new rockets: Atauúba (“incendiary arrow” – in Tupi), this rocket is a reformulation of the old LILE, that will serve to new purposes.
The Hybrid Team wants to launch 2 Atauúba rockets, the first (Atauúba-1) will be until march and will have only the basic telemetry, this launch will validate the rocket. The second (Atauúba-2), the rocket will contain a lot more of sensors and will able us to make several tests that will give us the basis for the bigger rocket that will be design in the end of the year.

Launch of new LILE rocket scheduled

January 2, 2012 Comments off

It was scheduled the launch of the new LILE rocket for the first quarter of 2012. This rocket will have basically the same configuration of the original rocket, but with a new telemetry based on open-source platform Arduino.

The rocket will be scaled to support the telemetry and a new parachute recovery system. A ground station will also be developed to receive the signal from the rocket and localize it after the flight.

Despite of being old and relatively less complex than the Santos-Dummont rockets, the LILE rocket was chosen for this next mission precisely because of it extreme simplicity, so we can test several systems that will serve as basis for subsystems, like control system, in bigger rockets.

The organization of the “N-PRIZE Prize” has just confirmed on his website ( the official inscriptions of two Brazilian teams to participate in this competition. They are: “Edge Of Space” as the 38th team entered and “Coyote Rockets” as the 39th team of 39 international teams already confirmed.

Just last week the organization of n-prize has announced the enrolling of a new team in the competition, the NTA (Núcleo Tecnológico do Agreste) a Brazilian team. We welcome the NTA as colleagues and friends because our success is the success of Brazil.

Hybrid Team’s new logo

May 9, 2011 Comments off

New project new logo. With the coming new test campaign and the improvements on the modular test bench the team decided to come up with a new logo. The responsible for the development of the new design was industrial designer João de Castro  a friend and collaborator of the group.

According to João the new design was aimed to reflect 2 different aspects: Have direct connection with the older logo, resemble the logo of the University of Brasilia (UnB) . The new logo represents a curved horizon line resembling the effect of Fisheye  lenses.

Ladies and gentlemen the new logo:

Status Report on UnB’s N-prize team

May 5, 2011 Comments off

This week we debut our blog and officially initiate our public activities. We have already made the firsts sketches of our nano satellite launcher. The launcher the SD-NP (SantosDumont N-prize) will be a multistage hybrid  rocket based in a Paraffin/H2O2 (Hydrogen Peroxide) combustion pair. The peroxide was chosen over the nitrous oxide (N2O), the oxidizer normally used by the team, due mainly to it’s low cost, R$ 3,8/kg contra R$42/kg do N2O, and it’s storability. Hydrogen peroxide in concentrations as hight as 70% (aqueous solution) can be easily acquired in Brasil and is produced here. The specific impulse, the efficiency of a rocket, of a paraffin/H2O2 (70%) rocket is around 190 s for low chamber pressures and as high as 242 s for high pressures (sea level values). The combination of medium specific impulses, very low costs and storability made H2O2 the obvious choice.

On the following weeks we will develop a MultiDisciplinary Optimization (MDO) algorithm to select the best configuration for the SD-NP.  The resulting optimum rocket will form the basis for the SD-NP’s final engineering design.

We are currently searching for sponsorship for light weight aluminum tubing and hydrogen peroxide.
