Payload Rocket Hercules III

The Hercules class payload transport system consists of a three stage rocket and a payload capsule. The initial concept postulated, due to jurisdictional regulations, that the rocket has to be launchable individually from any of it's stages. So, by powering the first stage only, an apogee of approximately 100 meters can be reached, 60-70m by powering the second stage alone, and around 80m using only the third stage. Ideally, all three stages would be powered, reaching an apogee of around 300m.
The payload capacity was to be at least 100 grams to allow for various telemetry systems.

Hercules III-a

The III-a variant is the first design study, computer-simulated only, without considerations for actual material availability. Note the large stabilizer fins.

Hercules III-b

The III-b variant has been designed as a techology demonstrator that uses standard components. As a result of the preceding simulations, the payload capacity could be increased to a theoretical maximum of 110g while reducing take-off weight by 12.5g. Reducing the stabilizer fin area, thereby reducing drag, increased the maximum altitude over that of the H III-a simulations.
