We finally have a first drawing of our rocket for N-Prize Race. Its preliminary design is just to help us to improve its aerodinamics.
Together with VLNS, we are calculating a better trajectory for VLFS (Fempto-Sattelite Rocket Launcher in Portuguese). But, due to some N-prize rules, we must to reduce costs. So, we are planning a ballistic trajectory with minimum control system.
This procedure implies in a low precision satellization but allow to keep launch cost below £999,99. Even with this simplification, our calculation show launcher capable to put about 50g in a 800km (SMA) orbit. Therefore, will be necessary to put about 35g of weight in upper stage to achive request orbit with a 15g satellite.
But, for us, the biggest challenge is to keep sattelite mass between limits. Unfortunatelly our recent design (transmissor only) was weighting above 40g. Send at least 9 orbit comprovation at about 800km will be our biggest achievement.
Soon as possible, we will show some drawings and static tests.
