After a few weeks without posts, we're back. And with a great news. Our group is participating on N-Prize competition.
We still working in our VLNS, but in break times we're projecting a very small and cheap rocket to reach Earth orbit with no more than £999,99.
We're making a few simulations to decide stage mass, ignition point and orbit insertion, to low cost and achieve desired performance.
We will launch this rocket (VLFS or Fempto-Satellite Launch Vehicle, in portuguese) on ground and in a launch rail (just like sounding rocket). I'ts preliminary design is showing about 327kg loaded and divided in 5 Stages. We still need to optimize its 1st and 2nd stage. 3rd, 4th and 5th stage will be tested soon.
While that, our main project (VLNS) is growing. Now we're working in a control system plataform to improve its confiability.
This year we hope to test a few components.
