I can see them standing round and agreeing that "if you can decribe it, I can build it", all the while their two clucky sons are trying to apply a basic sanity test to keep them from doing anything really lethal. "I'm almost certain you can't get hiold of one of those." "You'd be surpridsed what I can get hold of. I'm the Scientific Advisor to the Welsh Assembly! Bwah-ha-ha-ha-hah!"

[@bikerfirefarter7280]

Cardboard tube and cutter with an Aluminium pipe-support works. Also followed by polyester-resin, and/or polyester-resin and glass-fiber wrap, etc; surprisingly strong and light. And cast nozzles with 'clay' additives are good. I pre-cast 'thread' in the inside of the ends of the tube, using a tapered threaded pipe nipple as a former when making the tube (use a 'putty'-like filler such as car-body filler). I cast the cores in place using a polished brass rod, with a thin waxed paper wrap over a sugar-paper sleeve; the sugar-paper allows for the contraction of the setting casting, the core rod pulls out and then the sugar-paper peels out by twisting it, and any wax-paper (if it stick) burns away almost instantly on ignition. No 'drilling'. Once set up it's all fast/easy/clean/cheap. Ceramic paper is available but I've not used it, yet.

[@patrichausammann]

@@KD_Puvvadi By the way, this is not a new idea. During World War II, the Germans use rockets to launch their jet planes.

[@mduckernz]

Iron oxide, or other iron containing compounds like ferrocene, can accelerate the burn rate far in excess of any reduction in particle size of the ammonium perchlorate. The reason is that the rate limiting step is the decomposition of AP to perchloric acid, and this is ultimately limited by the fact that the AP forms a liquid layer on the burning surface, so smaller and smaller particles of AP don't help you past a point. This is why ferrocene can be much more effective than Fe2O3, as the iron it contains can mix in with the molten AP at a molecular level, rather than the molten AP being broken down over the surface of iron oxide particles (and iron containing plasma...)

We were behind an earthen hill. When ignited, after about 1/2 second it exploded. Neighbor came running out, the neighborhood started sending emails. I told the neighbor we were trying to make a rocket motor and the nozzle was too small. Wife actually came out and threatened to call the police on me. It was heard a mile away. I took the film, and looked at each frame, and calculated the parts were flying away over 100 MPH. A lot over. It was plastic, and we were shielded by trees. YES , BE SAFE.

Because if so, I'd like to see that trailer fly :P (assuming it's even possible to do it safely lol)

[@petevenuti7355]

I would guess 2, that is two per rocket, basin that on the following;. "Any model rocket using a single motor greater than 160 Newton-seconds of total impulse, or multiple motors with a total thrust of 320 Newton-seconds, is propelled by a combination of motors having a total of more than 125 grams (4.4 ounces) of propellant weight, or weighs more than 1500 grams (53 ounces) with motors installed, is classified as a high power rocket under National Fire Protection Association Standard 1127." Of course I don't think there's any law written telling you how many rockets you can strap to your back, ...I mean back of your trailer 😜. Also those are the limits without certification, I expect making a flying trailer might cause you to lose certification. That doesn't mean that for sure but I'm telling you if I was in charge you would!

@@petevenuti7355 the fact the language exists in the first place tells me I am claerly NOT the first person to ask the question lol! Thanks for the info!

I don't know how to define the effect of your works on my life but just let me tell you that you are one of the reasons which now I'm studying aerospace engineering in college. Thank you man ..

[@TechIngredients]

Really?! That's great.

[@Tony770jr]

I like the idea of the hybrid motor. I've seen the ones running nitrous oxide with a solid fuel. Other than solid fuel there is really no other choice for hobbyists. Cryo it way too complicated. Thanks for the entertaining videos..

[@TechIngredients]

That's next.

[@MrJimmyjammmy]

I think you can use peroxide.

[@NiHaoMike64]

Liquid fuel rockets are definitely practical for the hobbyist.

[@dandan-gf4jk]

​@@TechIngredients Hybrids are the worst of both worlds (at least on hobby scale), once you make the effort to go towards hybrids you might as well try a proper liquid engine, although this probably warrants making a real combustion chamber. There are lots of cheap (to buy and to work with) fuels, many with reasonable boiling point temperatures ex. propane or butane

[@Tony770jr]

@@dandan-gf4jk I'm more referring to cryo fuels like LOX and LH. Not butane or peroxide. They're on the weak side as far as thrust or specific impulse.

I have never wanted to hang out with someone as much as you. Love this stuff! Thank you

[@chrism4621]

Just curious, what do your neighbors think of Starbase North?

[@ortega_computacion]

loved every second of the video, cried of joy with the peter schilling major tom alussion.

[@skel3370r]

You probably make the dankest scrambled eggs

[@MrMancinorosso]

One of my favorite videos you've ever done!

[@dwaynezilla]

The unit for impulse is N·s (says "total impulse = __ N" a lot, ahhaha)

[@miqueaspromontorio3]

Yea, those N's be hella impulsive, bruh.

[@slrnuttall]

Fantastic job of both teaching and entertaining simultaneously!

[@Uncle-Duncan-Shack]

Best hour of my Sunday so far, after watching SXM-8 fly in to space this morning. The presentation is great, love the style. And the high speed video of the rocket burns is stunning. Those motors are nice, and graphing them to demonstrate how they burn is so valuable. The graphs demonstrate the different behaviours of the motors perfectly, one needs that for choice of motor. Keep up the good work, it keeps us motivated. Kind regards, South Africa

[@karllaun2427]

Really love your varied projects. An hour goes by and I barely notice....

[@naturalfreq]

That demo was great! It gave a good “scale” of the rocket motor impulse. Thanks!

[@mattp422]

Fantastic motors! Really beautiful burns. As usual, your in depth explanations and attention to detail and precision ("neatness counts") make your videos must see viewing for anyone with a love of applied science. Can’t wait for your next one.
