10:36 that reminds me of the stabilizer-stabilator thing with airplanes. When you have a stabilator the stabilizer is the elevator, so basically the stabilizer itself rotates the change the altitude. When you have a stabilizer, there is a separate elevator that moves on the back of the stabilizer. This is like the stabilizer.

Quick question: I see you are using a 3D printer to create your fin structure. WIll these not get hot and "melt" at supersonic speeds? This is fascinating. Just found the channel! Keep launching!

If you make a longer burn time and put explosives on it then it will be a icbm

Having no contextual understanding of rocketry I would suggest linear actuators that push out sections of the body to create drag on the desired side of the rocket body

Como você deixa seus foguetes tao estavel

"Thrust vectoring was just easier with fins" Insane lol. Very impressive stuff.

Don't feel too bad, Lockheed made a very similar connector mistake on the THAAD program. Missile went about 100 yard before burying itself into the desert. The connector was to load the guidance program, but when the wires pulled out they shorted the guidance system. So, no guidance. D'oh!

You should pack a survey or experiment and name it Science Jr or mystery goo

Amazing❤ And congrats🎉

Im 28 years old, former police Sgt., college grad, and father of 3....I look up this man. What an inspiration you are. Weather permitting, I am about 1 week from getting my PPL as I now pursue aviation full time! Hope to meet you some day!

Would love if you did those 3d flight models in future videos too. pretty sick to get a 3rd person pov.

@BPSpace Looks like you forgot to use the metal washer when you installed the ejection charge. Problem is the hole in the forward bulkhead that allows the delay drilling tool to be used is big enough that ejection gasses can decide the path of least resistance is through the nozzle of the motor. So after drilling your desired delay, you need to place the washer in the well, then add the Bp. I also like adding the bp a little bit at a time, tapping the motor to make sure the bp settles in the cavity above the delay charge.

INCREDIBLE!! So Awesome 👌

bro reinvented the conventional control surface (rally cool video this is a joke)

Fun videos, but more safety precautions should be in place, as wgoulding mentioned! How about doing a reaction video to the 1988 pepcon explosion? I was at UNLV in the Physics dept in 1988, and have never seen-heard-felt any unintentional explosion as intense! m.ua-cam.com/video/_1kTAX9uWcw/v-deo.html&pp=ygUecGVvY29uIGV4cGxvc2lvbiAgMTk4OCwgQU5UIFRW

Which cfd software did you use?

How did you learned electronics please tell us ❤️

are you aware that you look exactly like Elmo Musk?

❤

plp don't want to watch failure unfortunately, they want to see results

can u reduce the weight and increase the thrust

"These youtube and tv guys never show the formula 😏" 😳😳😳😳😳

Please make a video for all the costs of researching and making the rockets

absolutely *fascinating* clip at 1:27, where you can see the cushion of air underneath the parachute deflect the smoke! the air cushion is a lot bigger than i always assumed. is that clip elaborated upon in some other video?

Great stuff!!!!

eww unity lol

Fantastic! Congratulations brother!

There is a reason for all moving fins other than extreme manouvrability. At the end of WW2 aircraft became uncontrollable due to the elevator being behind the shockwave (where it looses effectiveness) just when they were very much needed because of the onset of Mach tuck (which is a nose-down moment on the lifting surface in transonic flow). The problem of controllablility was solved on the Bell X-1 with an all moving horizontal stabilizer. On supersonic missiles this is the all moving fin. Your trim tab seems to function more as a spoiler (so to create drag) than as an aerodynamic surface to direct the airflow. It definitely gets credits for a shoestring approach. Hope you don't mind me making a suggestion: spoilers don'' t necessarily have to be in the fin section, they might as well be in the aera where you would expect the canard fins or anywhere else on the vehicle. The obvious advantage of moving the spoilers away from the fins is the available space for the servo's. Now your fins can be thin again to reduce the drag. I hope this suggestion will help you past Mach 2 and eventually into space in a controlled manner.

I had no idea there were rocketry certs... i thought i could just buy an estes rocket and go... just keep adding stages ya know.

bro looks like elon musk jr.

This feels like ‘getting a job with Elon’, but with extra steps? Very interesting though 👍

New versions Sidewinder AIM-9X that does not have rollers has entirely different control system vector thrust + rear fins. While AIM-9L and before use only aerodynamic controls and rollers. I suggest look at python-5 layout - it has aerodynamic controls but it has very complex fins system (fixed carnard, moving ones, two roller moving fins and very large static tail fins)

Thru the whole length of the vid, one thing kept popping into mind was this: For control on the X-Y axis, a single, tapered spike on the nose, able to be pointed off-axis for 'steering'. This would eliminate downstream vortices from canards. Your tiny tabs on the back of the fins would take care of roll.

You are the perfect mix of youtuber and engineer, these videos are great and inspire people. Thank you... can't wait for the math video :)

When at Mach numbers do anything possible to not make the wind to catch anything. I would surely had used pure copper wires there tightly together, and no splices, since they were exposed and then covered the entire length with epoxy so the surface would have been smooth and very strong. Superglue is brittle epoxy have some give.

I’d use virtual canards using ducts with valves to create simulated cold gas thrusters. Been working on using this idea to make a virtual windscreen for my bike but haven’t had enough free time to really dive into it.

This is very inspiring!

So excited for starship!

"risky bisky risky batman" that line got me rolling on the floor lol

I guess everyday astronaut saying "space is easy and orbit is hard" is very relative. Great videos.

In the past, only a couple of objects could reach supersonic, the goal being INCREIDIBLY difficult, challenging, and made by tens of engineers, but now, even a random guy with a youtube channel can do so. How humanity advances so quickly is just too beautiful

I know I'm very late to the party, but could you also throttle a solid rocket by injecting some kind of fire suppressant into the motor?

What are those large square LEDs on the front of the board?

what is with the auto leveling mechanism that is used on old multi rotor hovercrafts and dual roter helicopters. i mean in your case it is driven by the acceleration force wich is directing the ball or wight on it down wards the rocket. yo with a lever system you can steer the fins with a infinite resolution. i know it is a mechanical stabilization but it works as long you accelerate. and it is not more heavy as your control electronics. you can do this with 3 fins and more if you want. they will be connected to each other so they work together. also this system tries to hold the rocket linear to your initial acceleration point. also yo can dampening this motion with a longer or/and softer rod from the control levers to the wight this will also increases your potential torque so you can fly faster. i have used this on one of my rocket. for the spinning part i used a rotating mass driven by the air like the rollerons but normally i build fpv racing planes. they are only wings and uses a x tail control set and as propulsion system i use 2 props that rotating in the opposite direction on one shaft and both running on a fixed rotation speed, pitch and and thrust angle ist controlled with a swashplate like a helicopter does. in the nose or more like a ball on a stick ist sitting the fpv camera with 260° vertical and horizontal freedom and can also rotate 90° is controlled with my fpv googles. i use only analog transmitter 2 for the control and 2 for the video so if one cuts out i am still able to control. each transmitter has his own battery. i use 2 flight computer and wich are doing the exact same sfuff but all signals going over a 2 way relay. this means the relays are always on and passing the signal from controller 1 to the controls but if controller 1 fails i can switch manually to controler 2 or if the power source of controler one fails this happen automatically. i know this seams overkill but given this rc plane is able to hit 360kmh or more and flies normally on a height of 10cm to 5m over the ground seems for me as to be necessary. also it has a weight if 1.3kg. i know it uses a over complicated mechanistic system but i love to fly analog systems also there are easy to fix and there is no electronic that can freak out. it is fast, makes fun to fly, sounds cool and with the the fpv setup i use you have the feeling you are sitting really in this thing. i mean ya i crashed it many times and needed to rebuild the whole plane but this means always overthink things and build something better.

what if you spin the fin can to control it

In my country is illegal homemade rocket propeller.

I agree that small control surfaces in the fins are the way to go, but I'm curious why you haven't mentioned something. Is there a particular reason you're avoiding using cables and an actuator higher up in the rocket? Im sure you've thoght of it but I was surprised you didn't mention it. Seems like potentially a very elegant solution. The main challenge would be making sure there's no play or backlash, but there are multiple ways to ensure this, such as having a motor (gently) fighting against a spring so there is always tension in the system. TLDR you might not have to mount servo motors inside your fin for this approach, allowing the fins to be a thinner and more efficient shape, not to mention far easier to make in composites.

Guess you are TOO IGNORANT to pay attention to GERMANY WWII ROCKETS! 75 YEARS AGO! DUMBING DOWN THE US, by LIBERAL DEMOCRATS, IS WORKING!
