“Why aren’t you making your own rocket fuel?” He’s in a country where somebody attempting to use explosives to blow up Parliament is noted as an annual event every November. It’s probably a given that messing with explosives isn’t really allowed.
@@Noone-l6g You can't get KNO3 easily anywhere in Europe. It's probably for the better because of making explosives but I really want to build some rockets 😅
@@josefstalin4532 like in my country, it probably wasnt illegal to make rocket fuel until a certain incident in a country where it is still unbelievably legal to make rocket fuel.
Thats an awesome rocket! Congrats! I can't help notice that both your Ender 3's have the spool mounted on top. I've done the same, but I found printing a spool spacer made a big improvement in printing, preventing the spool from wobbling the frame as it pulled round, made it much smoother and less artefacts in the print.
I remember the first Sputnik, we had no commercial options so motor design, chemicals, and eardrum shattering explosions was part of that learning process. Fortunately I grew up in a neighborhood of Westinghouse chemists, and Bell Aerospace engineers building the Agena rocket for America's Project Gemini manned spacecraft program. I had all kinds of expert guidance, that would let their grass grown and ignore their wives and children to bundle in my parents basement do stress and strain calculations, teaching me use of a sliderule, no calculators or computers smaller than a mainframe IBM in those days. It was great fun, the local Fire Marshall had certain reservations.
Hey James, many years ago at a UKARA event, a chap had a new high power rocket motor that didn't require an explosives license, and it might be time to revisit the idea. It was an injection molded (because this was pre-3D printing) ABS plastic rocket engine vessel, with a thrust nozzle, all in one piece. He had the top threaded for a feed from an NO2 tank, pre-filled the vessel with O2 to get things rolling (simple fill through the nozzle), and ignited the actual wall of the vessel using a spark across some speaker wire, from a fluorescent tube starter. This could be 3D printed easily, with some fluffy chaff to help the conflagration get started inside the vessel. You just need gas, and some solenoid activated valves, and you are flying.
One thing to note from this is that things that you don't think can happen will. Even a bigger stronger camera tray or better attached nose is not a guarantee. Consider simple and safe backup is a great way to mitigate risk for critical (or at least high cost) failures (like loosing your camera). One example of how to mitigate this would be a tether line from the camera strap/tripod mount to the parachute anchor. Good luck on your next launch and stay safe.
In 1978 I built my first Estes 2 stage rocket that I bought at a local hobby shop. It featured a first stage with a 0 second delay on the ejection charge which then lit the 2nd stage off. Unfortunately being a kid without much money on the 2nd flight I used an existing C engine I had in my box which had a 1 or 2 second delay regular engine. On that second flight after the first stage was done the rocket tipped over at apogee and then the 2nd stage fired... it went way into the woods at the edge of our launching field and was never found again despite days of searching. I loved rockets as a kid and homebuilt 2 and 3 stage rockets out of cardboard tubes are really nothing new, though building them with GPS and cameras certainly is!
As a Finnish person, I can tell you that 3c is cold! Our fingers feel just as cold there as yours. Of course someone might suggest some gloves but hey, cold is cold no matter where you are. Great vid!
Yup those graphs make sense to me because once the motor stops burning the drag force is causing deacceleration. That 1st stage motor was VERY powerful!
Canadian here, can confirm you would get completely slagged for complaining about 3°C The most underrated tip I can give you to avoid silly mistakes is, make checklists and use them. They sound ridiculous, but they make such a difference by allowing you to deal with unexpected problems/situations without loosing track of the mission critical procedures
I'm sure you've already done so, but as a reminder: Let those neighbors know about the lost camera. They seem to be nice enough (and ride around the field enough) to stumble upon it eventually and let you have it back. It may also be good to tether everything to a single point with streamers in the next rocket. That way in the event of a catastrophic failure the streamers will act as air brakes for parts to make sure they don't fly away too far, as well as leaving easy to spot markers on the ground. Regular survey/marking tape works well. Of course once the tests are done and you're going for the absolute top flight, the streamers can be removed to lighten up the rocket by those few grams.
Great launch! My launch rail is a 2 meter curtain rail, reinforced with 20mm square tubing. Mounted on a tripod that is 1 meter high. Giving a total of 3 meters. We have level 2 in South Africa. So that is full J-Class motors. We do several km high flights here. So good luck with your project. Tip. Build a secured E-Bay for your electronics and cameras. Because you are limited to motor ejection, you may have to look at a body split ejection. Where the e-bay and the nosecone acts as a single, long nosecone, and is attached to the booster by a shock cord/recovery harness.
I would imagine your intelligence knows no bounds. Too bad all young people are not like you are, imagine what the world might be like if they were! Love your content!
A lot of GPS devices won't update if they're traveling too fast or too high. It's hard to imagine your rocket was going too fast but it's something to keep in mind. I know high altitude balloon projects run into this limitation. Thanks for sharing your projects with us. They're a lot of fun to watch.
With a FSI F-100-6 motor and a small rocket, we got mach1 at 900 feet altitude, and the small boom was herd at 1000 feet away from the pad, total cost $11 back in 1992. Also with a dual stage FSI e5-0 plus e5-6 and small rocket got to over 4000 feet, with 9 seconds of total burn, the good old days.
Funny you mentioned Finnish people. Watching the your previous video I actually giggled a bit in my head when you were so cold in a thick jacket, and to me it looked like weather I'd probably be comfortable in wearing a long sleeve t-shirt or something. =)) Greetings from Finland, thanks for all the great videos!
A few thoughts regarding the nose cone, that you've probably already considered. If you screw or bolt it to the cardboard 2nd stage tube, you run the risk of the tube tearing if the payload sled shifts. The first thing I'd try is to either design the sled so it is long enough to completely fill the tube length or add some lightweight filler between the sled and the base of the nose cone. The second thing would be to make the base of the nosecone that slides into the tube deeper. That way you can anchor it to the tube farther back from the edge which should give it more strength. Maybe even use some fiberglass strapping tape and run a band of that around the tube where you're going to put the anchor screws. . Excellent launch even with the oops! Hopefully the camera is well marked and whoever finds it, if anyone does, gets in touch with you soon about it!
I have been launching my rockets in the winter on a frozen lake in the states by the Canada border, works great, I paint the rockets red to find them in the snow, working on one with 4 E12 engines
Use an 80/20 (t-slot) aluminum extrusion for your launch rail. you can get them in 10ft lengths uncut fairly easily (and longer by order) and many of the commercial and 3d printable launch lugs are designed to fit this profile
I just have to comment about the chilly winter weather. As you predicted, I am Canadian and on this winter morning it is -32 degrees. Doesn’t matter Celsius or Fahrenheit... it’s chilly.
Canadian here, I can give you a pass for saying it's "cold" when it's 3 C out, as 11 years ago I moved to Costa Rica, and the locals here tend to get cold around 18 C, and hot at 30 C. I have a new people to harass in my stereotypically Canadian passive aggressive way. :)
@@Not_so_Jinx India's temperature difference annually more than 80 degrees? I know it can get really hot in India, not a place I'd enjoy (after all my country is the second coldest annually in the world, only slightly behind Russia). If India does vary annually more than 80 degrees, damn man!
@@canoozie 80° F ? Or 80°C if C then that is too hot to be alive man , that's to much I don't know if humans can survive in 80° but one thing i know is that you can get see a big variation in temp like in Siachen glacier goes to -50° C minimum and leh ladakh which goes to -15° C in southern parts of india near equator line the states are more hotter and some even have the modest temp you can find like Mumbai, Nasik . You can also experience a well humid weather in eastern parts of India as well as the south eastern part. Basically you can experience this variation in country itself.
Don't worry about what Canadians and Finns think! Their winters are cold and DRY British winters cold and WET the chill factor difference is enormous, I used to cross the road ( in Sweden)to my local shop 60 yards away in a T-shirt in -15c weather with no real hardship -20c might have been! but wet windy and cold nakes apparen temperature much colder!
Always use a short burn, higher thrust Blue Thunder type motor in the booster to get the rocket moving straight vertical. Longer burn motor in the sustainer since it is already moving fast. Nothing worse that the rocket going horizontal when the second stage lights. In us you also need a waiver from the FAA. Rules change, but I recall a one pound loaded weight for a G motor. An H motor you will prob only fly with a club that has to get a waiver..
I just watched these 2 videos back to back and almost ALMOST posted on your first video, that a lightweight FPV system with a flight controller with GPS and built in OSD (they also have blackbox data recording on SD card) would be great and would provide you with a LOT more data to work with. Watching the launch on the screen on the ground and recording it with a DVR will be brilliant, but allow me to recommend an on board DVR to also record the footage being sent to the Video Transmitter. It will guarantee that the flight data you choose to display on the screen will still be visible as you're not relying on the transmitted video link to the ground station. The OSD on a flight controller using iNav can display 3D speed which is what you want... unlike the GPS logger you have which only shows you horizontal/ground speed. Anyway, good luck with this and I look forward to seeing you implement FPV into this Project!!! Keep it up, you've just grabbed a new subscriber 😊👍😎🚀🚀🚀
Tech Ingredients has an amazing video on rocket fuel that is just Sugar with an Oxidizer, these are street legal products to have, so combining them shouldn't be illegal :D
One question: even though it gets pretty close to the speed of sound, it never breaks the sound barrier, so why did you make an almost cone-shaped tip, instead of a more rounded one, that would perform better at subsonic speed? P.S. sorry for the English, I'm not a native speaker
Guessing here, but usually the long nose shape is used for 2 reasons. One is that to most people it looks fast. Two is to move the center of pressure farther forwards.
There are a variety of nosecones designs that are effective in the subsonic range, and the ogive shape (which is what that looks like) is a reasonable choice for subsonic. Conical isn't actually the best shape for Mach breaking however, and some of the power series and the Haack series shapes (also known as a Von Kármán or LD nosecone) are much better through and past mach
As much thrust as you're using, maybe you should consider using aluminium tubing for the main body of the rocket. You'd sacrifice some weight, but it would be much more durable and less likely to be damaged in a rough landing.
Like my friends, the Canadians, I must protest! Your constant complaining over the years about your weather is intolerable, and borderline criminal! *Here in Florida,* we too suffer ill tremendously during the worst of our winter. For days, whole days(!), we have to wear long sleeved shirts, sometimes even a jacket!!! There is a tale, passed over generations, of a year where, contrary to all known Florida history, where white power drizzled slowly from the sky. Glorious, glimmering snow lit colorfully by the ambulances, attending to those who tried to inhale it. So do please refrain from complaining about your _Alleged_ cold weather. I touched my monitor while watching your video, and I know you're filming at a warm location! Love, A Florida Man

*Here in Florida,* we too suffer ill tremendously during the worst of our winter. For days, whole days(!), we have to wear long sleeved shirts, sometimes even a jacket!!!
There is a tale, passed over generations, of a year where, contrary to all known Florida history, where white power drizzled slowly from the sky. Glorious, glimmering snow lit colorfully by the ambulances, attending to those who tried to inhale it.
So do please refrain from complaining about your _Alleged_ cold weather. I touched my monitor while watching your video, and I know you're filming at a warm location!
Love, A Florida Man
