For the past 6 months or so Oberth and I have been plugging away at another iteration of the rocket we flew last September. Last weekend at Aeropac's Mudrock we flew the rocket and managed to squeeze out a little more altitude and speed than the previous configuration. Now that we don't have a rocket to construct, its build thread time!
We hadn't really thought of a name for the rocket on launch day and Tony (tfish) decided the rocket should be called "My Little Pony." Tony put it on the flight card which I guess makes it the official name. Since the rocket is really an iteration on Honey Badger 2, and my creativity is limited, the intended name was HB2.1.
Improving the Design
The launch of Honey Badger Two was by all measures successful, but realizing that we were still not design optimized in a few areas we decided to take another look at polishing the design around the N5000 before moving to bigger and better things. The motor not the best for altitude but it had proven reliable and we had a baseline for comparison. We identified four categories of improvement; reliability, mass reduction, drag reduction, and motor efficiency and prepared to implement them across the following:
Fins:
Reliability, Drag Reduction, Mass Reduction
Motor Case:
Mass Reduction, Drag Reduction
Nosecone:
Serious Mass Reduction
Electronics:
Reliability, Mass Reduction
Motor Components:
Mass Reduction, efficiency
The ultimate goal was to move to a larger design with confidence in the fins and electronics. The secondary goal was to break 60k feet with a mid sized N motor.
We'll update this thread over the next couple weeks with all the pictures taken during the launch, flight and recovery.
