My build of the Rosuette A which is Blue Dog Bureau’s approximation of the Diamant A rocket which was France’s first rocket which launched their first satellite, the Asterix, in 1965. The launcher is three stages with a lower liquid stage followed by two solid stages. This makes precise orbits impossible but provides a lot of power to get a small payload into a relatively high orbit.

The first stage, a liquid engine with an additional four verniers, should get your payload into the upper atmosphere with the second stage, the first solid stage, taking over and sending your apogee to somewhere between 250 and 700km (some tests put it as high as 900). The third and final stage will reach the perigee and put you into an orbit along with reaching your apogee even further. Most of my test flights put me around a 1,500km apogee with a perigee between 200 and 500km however you can time the final stage’s firing to adjust this considerably.

The BDD’s approximation of the Asterix has been included as a test payload but any payload that can both fit under the fairings and is approximately 100kg should give you a similar performance. Due to the power behind the solid stages you could possibly launch an even heavier payload into a lower orbit but it may have a negative effect on your initial launch TWR (thrust-to-weight ratio).

I have adjusted some of the thrust limits and fuel supplies to several stages to keep the rocket more manageable and to give it the appearance of different capabilities from other Rosuette variants.
