In order to understand high power rocketry enough to launch and successfully recover an L1 rocket, you must read, live, and understand the following information.
L1 rocket certification allows individuals to launch rockets with an impulse up to 640 Ns. The requirements include:
- The airframe must be built by the user with external markings for the centers of gravity and pressure. Rocket kits may be used.
- A standard parachute must be used for recovery, even if a dual-deployment method is used.
- An H or I motor may be used (with impulse < 640 Ns).
- No electronics or altimeter is required.
Following the launch, the rocket will be inspected; should the airframe be deemed suitable for flight given a new motor, it will have passed L1 certification. Failed deployment, motor cato, drifting beyond a particular range (see launch officer), or the violation of other safety codes will result in a failure. L1 certification, however, is an excellent introduction to the basic operations of rockets and recovery!
