L3 Cert Flight

The GLR Sledgehammer roared off the pad on an Aerotech M1315 motor, flying straight and punching a hole through the clouds.


Here is a short video from the flight line. It gives a sense of the sound, but misses the subwoofer feel…


She flew perfectly, the redundant flight computers performed according to plan, and the airframe returned in sections on two huge parachutes with nary a scratch. And that was all necessary to get my L3 Certification with Tripoli Rocketry Association. Now I can launch the really big stuff... woot!


Also, I’ll post the design schematics below. This is serial #001 of the Giant Leap Rocketry upscaled Sledgehammer, a unique and elegant Air Force-inspired design.
