Three-part solid rocket aiming for a propulsive tail landing

Most hobby rockets come home under a parachute, because recovery is a solved problem in this hobby. This build throws that out: it is a solid motor rocket with custom thrust vector control, and the aim is a propulsive vertical landing in the style of Falcon 9. For a first rocket that is a bold brief, and the work behind it looks serious.



The layout is a central core flanked by two detachable side boosters. Steering comes from a gimbal driven by two micro servos through linkage pushrods, with ten degrees of deflection in each axis. The electronics stack carries a buzzer, terminal blocks and a microSD card reader breakout. Airframe sections were drawn up in Autodesk Fusion 360, and Python simulation scripts back the whole design.



What stands out to me is the discipline of the test programme. A static fire was run on a wooden A-frame swing structure, and the closing analysis shows the telemetry from that test correlating with the simulation models. PID controller parameters were tuned using multi-panel trajectory and attitude plots, a far more careful route than eyeballing gains. CAD previews of a launch pad structure for an upcoming flight test exist as well, so the next step is already in motion.



The open question is the touchdown itself. Folding-out air brakes are planned to hit the exact speed needed while falling, and the landing legs are meant to be stiff and big to maximise the chance of staying upright. A retro motor may also be used if a little extra slowdown is needed. Whether all of that comes together on the first landing attempt is the part I am most curious about.

Ten degrees per axis from two micro servos on pushrods looks like a tidy solution to me. The trade I see is that any slop in a servo-to-pushrod-to-gimbal chain matters most at small deflections, and small deflections are exactly what a hover and touchdown need. Keeping that linkage short and rigid is where I would spend my effort.

Curious what motor this is meant to fly on. Is it something off the shelf, and is one motor intended to do both the ascent and the landing burn, or would those be separate burns entirely?

The maker has confirmed it flies a prepackaged 18mm black powder motor. On the descent side, using a retro motor has been mentioned as an option if slowing down a little bit turns out to be necessary. That is as far as the motor plan has been spelled out.

Since the static fire telemetry already correlates with the simulation models, a useful variation would be running the Python scripts with the planned folding air brakes deployed at different fall speeds before the flight test. Pinning down deployment timing on the ground seems safer than gambling a landing attempt on a first guess.
