This is exceptional. Joe Barnard didn't use a leg dampening with a ratchet that probably could've grantef him a landing sooner. Also, the fact that you could launch again the same day shows a great approach to your design process, and proves that simpler, quicker testing is more important than almost anything, as well as that the product is not the product itself but the whole process of testing and the production.

Very nice engineering! The lunar module had similar dampening to this - except theirs didn't need to be reused. They absorbed the impact using aluminium crumple zones. I think this is also the reason the ladder was so far off the ground as the landing impact was less than they expected, so it didn't crumple all the way. Can't wait to see your next project!

Very cool. Back in late '74 while I was in the eighth grade I bought a Centuri Eagle which included a launch pad. The original launch wire bent so I replaced with one that had spring steel. The rocket was great--plastic fins, plastic nose cone, and chute which I later replaced with a streamer. With a C6-5 it could reach 1100 feet and with a C6-7, 2000 feet but I preferred a C6-5 so I would not lose the rocket on the way down. Sometimes the chute would not deploy but the rocket, with its strong plastic fins, never broke. Called a 'beginners' rocket, that depended on engine choice and the size of the launch field. I always used my high schools launch field, and I flew the rocket until 77, so I got in an amazing number of flights until the rocket was lost when it got caught by an odd thermal. Your rocket is quite cool. Where I live now, in Phoenix Arizona, I can see the Space X launches from Vandenberg depending on their flight path--amazing since the base is 500 miles distant as the crow flies. This link is a bit of history about the Centuri Eagle, which I also demonstrated once for my grammar school, and the minute it reached just below the cloud base, it started to pour so my principal--still good friends in his late 80's, said I and my assistant 'seeded the clouds'. I graduated from that school the following summer and still have my eighth grade diploma. www.rocketreviews.com/centuri-engineering-co-screaming-eagle-john-lee.html

I was thinking about the motors. Model rocket engine design is simplistic, with a hollow cylinder of fuel grain burning on the inside face. There are two processes in motion: one, the engine gets lighter over time, increasing acceleration towards the end of the burn. And two, the burning surface is larger toward the end of the burn, which means more thrust and higher acceleration. It seems if you are willing to put in some work, you could taper off the thrust in a predictable manner. The Space Shuttle SRBs start with a star-shaped (more like sprocket-shaped) core cast into the grain. This gives it way more surface area at the beginning of the burn. If you were to make a clay star-shaped (sprocket-shaped) casing, with the teeth on the inside wall, when the grain is cast into the casing, it would have a tapered acceleration toward the end. The burning surface would decrease over time. Tinkering with the number of teeth in the sprocket, the depth and taper angle, you would be able to fine-tune the thrust to your liking. I've never seen anyone try this. If anyone has a video on it, it would be fascinating to watch.
@hagerty19522 ай бұрын
James - You've just touched on a subject that has religious ferocity in amateur rocketry almost as intense as the motor/engine one in model rocketry! I actually got to crawl around inside the bore of a Shuttle SRB engineering mockup (well, the top segment, anyway) as part of a job I was quoting. This was a completely accurate casting, it just didn't have any AP in it (only the PB rubber and aluminum powder). I had to stick my head into the narrow neck-down at the top to look down the slots in the grain. There were 11 of them (always an odd number so that no two openings face each other) and more that a little awe-inspiring, considering what this machine does!

Instead of having a suspension, wouldn't you be able to have landing spikes instead of legs. If the rocket comes down, it would drive the spikes into the ground, preventing it from jumping back up, because of the sliding friction with the ground. Just a thought, don't know if this is viable. And this would obviously only work when landing on soft surfaces.

That would be pretty likely to just tip over if there were too much lateral velocity. It's also questionable whether the thing weighs enough to drive itself deep enough to secure itself.

May even consider using five legs. Five legs make it even harder to tip over. The government had tons of four leg chairs they bought for everyone in the electronics repair shop. And so many were easily able to tip them over trying to slide them around. So they got rid of all the four legged chairs and bought five legged chair and that stopped the tip over instantly... Just an idea!

I'd change one bit of the suspension: A delayed reset. After deployment, if it bounces or takes off again, it'd allow you multiple tries at landing instead of the one-shot catch mechanism. A piston would let you control the reset timing with air orifice size. Spring to absorb & dampener to extend the release time of that absorbed energy.

Browning A5 shotgun uses short recoil operating principle. The barrel reciprocates to cycle the action. Its damper is a split bronze ring that slides on the magazine tube. The barrel has a guide ring that also slides on the magazine tube. This ring has a female internal chamfer which mates to the bronze ring’s external chamfer. When the gun fires the barrel starts back and the chamfers squeeze the bronze ring on the magazine tube for friction damping. (Also the barrel recoil spring is between the bronze ring and the receiver…so the ring always has a bit of force on it) The system in the video does not dissipate energy, but transfers it to the spring.

I think air bleed dampers might get a better landing result than springs. A bit like a bicycle pump type setup. You could 3D print them also, using solid and flexible filament for the piston seal. Basically make a miniature cylinder pump with bleed valve on each leg. It could have a gentle spring inside to return the piston when no load is present. i.e. When the model rocket is airborne. With a miniature setup on each landing leg, this system could significantly reduce impact forces, making landings smoother and protecting the rocket from damage.

Hey just a suggestion on the software side of things. changes to your code can be wrapped in "feature flags" controlled by a config setting, so that if it causes major issues turning it off on the fly can be controlled via config changes rather than having to re deploy all of your code. Its something we use in the software industry very commonly and helps with mitigating risk, as well as allowing us to turn on experimental features in test environments while keeping the the old functionality available. Great job on the project and successfully landing with the newest changes!

Well done 👍👍👍 is it at all possible to mount a small stabilization gyroscope in there so that your rocket is kept gyro stabilized.... Also, have you ever encountered electrically controlled solid fuel rocket motors ? They only burn and thrust as long as there is a small electrical current going to the fuel... In such a manner, could you not use a motor controller chip process for precise deceleration. Combined that with the gyros stabilization and you could have some very interesting precision flights as well as precision landings !!!
@robertobissanti2 ай бұрын
Excellent work. If I can suggest something: the dumping system should be made by spring and shock absorber, there are many shock absorber useful for this use, like as the gas spring used in the kitchen. The point, more difficult, it’s the use of aerodynamic stabilization system, like as that mounted in spaceX rocket, they’re a three grids opened sideways. Even more difficult would be a greater regulation of the thrust, which should not turn off completely until the end of the landing. Finally, why not just use three legs instead of four? You should get more stability and reduce weight, cost and complexity. Good work and congratulations again for your commitment.
