The challenge of moving from a laboratory set up and into a flyable - in line - type rocket is not as simple as it may sound.
By early 2009 Copenhagen Subrobitals was building flightware in the form of a nitrous oxide / epoxy workhorse motor named HATV.
The HATV is a powerful, yet crude, 220 mm diameter hybrid booster.
It produces some 12 kN thrust with a combustion time of 20 seconds.
The thrust time history is very regressive making it ideal for a passive stable rocket that needs high initial acceleration followed by a longer phase of sustained thrust.
The HATV design work very well, and they are the first step to closing the gap form amateur size rockets to the very powerful and dependable big machines needed to propel us to space.
