Would this motor work for what I'm doing?

Well 2 G80's sent my 4" rocket to 1200', so totally possible

Well let's just say we used your rocket. To get it to space, we would need 440 G80's to get it there. Space is 264,000 feet from the sea level. 264,000/1200=220 but that was with 2 rockets, so you have to multiply by 2. 220x2=440. So plausible, but not practical.

Lok I'm going to step aside here for a second from the hailstorm of crap you're about to get.


If you're interested in rocketry, thats awesome. Design and build some small stuff so you have an actual gauge and idea of what you're talking about. Because right now you're talking about trying to fly one of these to the moon.

Official international definition of space is ~328083 ft ASL. Also I can promise things do not scale linearly like that.

True, but 264k feet is considered "space" in the US. But either way, it was as theoretical. You obviously can't strap 440 rocket motors to a 4" rocket and expect it to reach low orbit [emoji23]

Maybe this article will help simplify things enough for you...

If you want to be able to design and build a rocket to hit 200+ kft ASL, you need to intimately understand this...

Anything less is pissing straight in the air and wondering why it's raining.

Anyone know how this guy did it?

If you bothered to click the link in the description, you would see this..

https://ddeville.com/derek/Qu8k.html

A "Q" class motor, with fins and a nose cone, basically. No wasted weight, the rocket motor is the body of the rocket. It's a custom designed and built motor, not a hobby motor or cluster of hobby motors.

I may be mistaken but don't usually people custom build their own motors for hobby use at some point anyhow? Or have someone they know do it for them?
So this guy must have been with a government agency, not a hobby rocketeer or group of rocketeers?

I signed up on this site largely because that video fascinated me. This seemed like a decent place to question it and the reality of getting to space on a "hobby" motor

Rain, you seem a very intelligent and inquisitive young man...
That's wonderful, thinking and dreaming will forward you in life...
You just keep on dreaming of super cool things
and trying to figure out solutions to obstacles ...

Show this idea at NASA. There are obviously quite distressed when sending astronauts into space with Russian rockets

seems funny you say your NAR level 1 and don't know about the HPRSC #3 for motors.

rAIN, you seem like you have good intentions. The problem is, they just won't work. Download a copy of Openrocket and play around with numbers. You'll see that it isn't as easy as you think it is. I'm working on a rocket right now that is a SINGLE baby K motor, 38mm diameter. With everything INSANELY optimized I can only hit around 18-19K at most. Ridiculously optimized M's are only hitting 40,000 at most.

I hate to say it, but you're NOT going to hit space on anything short of 2 L3 sized motors in a 2 stage rocket.

Not only 2 and 200 such motors can not get orbital speed of eight kilometers per second. Only rough mathematical reasoning can be shown that the orbit can be displayed only in rocket in that fuel is 90% of the mass of the rocket and engine has very good parameters.
Rather, the issue is interesting, does anyone know what is the lightest rocket delivered the satellite in orbit? The standard weight is 200+ tons but I think it can be lighter. Of course the satellite will be tiny.

I think it is pretty funny you are smart enough to quote the code thinking either,
A) in the video this guy launched and magically made my own motor
B) i am a level one who makes his own motors
C) the guy in the video is part of any rocketry affiliation and somehow I am tied to this video
Z) you must be a genious and you supercede my certification with the safety code through this video of a motor I didn't make but I did launch
Z.1) you obviously don't realize there are hybrid motors and designated test sites for hybrid motors to ensure safety with bunkers and such

I should probably check the code on that one again. I'll get back to you.
Point is, dude scraped space. Scaled composites won the X Prize with spaceship one at around the same altitude. It was considered space. So to me, this guy has reached space.
NASA is a government operation to funnel money into something much larger than what they tell us. I'd believe any private corporation. Over the US government any day.

RaIn I think you can do it. I think private companies are proving it can be done. You just have to bend your mind and thinking into something nobody has ever thought of backed by a lot of education to present a thorough plan of action. Somebody with money will pick it up if you are smart enough to go for it.
Work for some of these companies who do this stuff and it will be a lot easier to get your ideas on paper and presented. Plus you have entire groups of analysts and experts to help you.
Bunch o Debby downers.

Have you ever worked for the US government NASA or a company significantly influencing the two?
Don't say Lockheed or boeing or any of that crap. Is all they do is buy the prints from someone else and jack up the prices.
So, have you?

Must of hit a nerve :eyeroll:

Actually, yes. I do. Do you want access to a bulk tin foil discount or something?

The Lambda 4S from Japan was the smallest rocket to put something in orbit. It weighed 20,700lbs used 4 stages and could put 57 lbs into orbit

Nope because I do too. I know for a fact, without question NASA being "defunded" is a joke and all that money is still flowing. Far more America underground than above it.
Good luck liberalizing your tin foil hats to everyone.
Liberty for freedom everyone. Yes we can.

So you work for spike TV in the early 90s about show talking about area 51? I for sure am not talking about area 51. NASA and the underground cities from Malibu to the Midwest maybe... and the money for NASA.
Everyone thinks anyone is a cooook talking about it until it comes out truth.
Sighs. Oh well. Take care

Maybe you want to check in with Ralph Kramden, He'll help you get into space.

BTW I use my mom's strainer, works better then tin foil.

That XKCD cartoon made one false assumption. These are Estes E9 motors. It won't reach space. It will roar off the pad for about 0.1 secs and then blow up spectacularly. :lol:

This is the smallest rocket that I could find. Able to put a small satellite of low orbit. As you can see biger of any amateur rocket you have seen. It should also be launched from an airplane at 40,000 feet.
On the other hand the payload is 400 kg. Mass of rocket 18 500 kg.
Payload of the rocket is 2% of its mass. So if we consider that in less rocket it will be 1% it does not seem quite impossible. In satellite 0.3kg rocket is about 20 kg But if it is launched from an airplane at 40,000 feet.In realistic to think that 0.3 kg satellite is 0.05% of the mass of the rocket. Then it gets a rocket 600 kg.

Two words for one person and such ready engines is mission impossible. But powerful organization with many members and own engines is not impossible.

Pulse detonation propulsion, baby!

its good to see you interested, rain. theres a couple things im thinkin-
what size motor to get into space.....welp it isn't really what size. its how much thrust necessary.
so, getting INTO space- breaking the earths gravitational pull- escape velocity- requires a speed of about 25,000 miles per hour.
just something to think about.
