alpha tech

Me and my brother and maybe one other person. 1st plan is to build a rocket that will get to space then based on how well it goes we will start for orbit. none yet. the lambda is a 26 kilo launcher I want a 5 kilo launcher for like a CubeSat of some kind .

Raspberry Pi's have a NOIR camera that has no IR filter so it sees the thermal image. I also need sensor and data dump on the Arduino's

if there is an explosion I will hear it and cover and if it launches I will watch it. I don't have a video camera . photo only

the electronics will be hard because we have to code the Arduinos our selves and figure out how to keep power and data to it. I am not making rocket candy for the actual rocket I am making test rockets for them. the real SRF will be of a higher Isp 15 meters and use the old duck and cover method. I will build a box later when I have electrical components ready for manual ignition I have old launcher box from old estes rocket so I will use that right now

I've looked at liquid fuel engines and I will need the following 1. A Turbo Pump / Turbine 2. A Pre Burner 3. Fuel/Oxidizer Pumps 4. An Injector. 5 Pressure tanks. now on what somebody said a while back about a the smallest craft ever attempted was by JAXA well they were probably trying to put a payload and that is why it was big. now to the control of the spacecraft while it is in space for staging an retro. I live near the lake, so I was wanting to use my surroundings as much as I can and landing it in the water seems pretty obvious but I need a way to talk to it thru GPS. or satellite. but if I use Arduino and make a PGNS and a AGC I can get predictions where it will land but nothing more than that because It will be automated the whole flight and that is something that I want and don't at the same time. the recovery system will be a parachute and a reserve also I want a backup to save video and other like record it to a chip and Isolate that chip to where if I have to abort like on little joe 2 where misassembled gyros caused it to go out of control and explode.

well I pretty much had all of that I haven't launched anything yet. I need a basic design for a test model that is solid and needs to incorporate the following things. thrust vectoring or gimbal (what is the difference between them?) Fin control and guidance for electronics testing. I've watched the king of random and I'm going to make the solid fuel he made Scott had info on how you ignite your engine by hypergolic fuel in the pre burner,

Ok back on topic. these certain safety measures have been taken 1. Safety glasses/ wielding helmets/goggles/aprons 2. Respirator, and all other stuff I may or may not have can be acquired a the nearest harbor freight tool store 3. 55 gallon oil drum to hide behind (may upgrade later) 4 and a test pit. (currently in construction). ok so The Liquid Fuel engine How Much Thrust do I need it to produce? How hot will the gas be. What kind of alloy do I need. Get as much Isp as I can. Figure an ignition solution. Thrust vectoring, gimbal, making the Tanks for fuel and oxidizer I will be making regular solid rockets to get the gyros and electrical components right. the electrical components will be the most difficult thing to get to work

90 % of a rockets mass is fuel

the isp, delta v, olberth effect ect.

i know the math and science behind making it. i just need to build it

took 3 guys to hold it

our town is poor

fuel dump

how bout put a bomb on it so it doesn't turn into a bomb that way it will incinerate before it hits the ground. like a spy satellite

also for safety is the revenue man gonna get me for making moonshine which is ethanol for rocket fuel

i just freaking guess engineered this with minimal research and if i wanted to build a bomb i would build a bomb and not a rocket. you, you did good this will help me some

seriously i haven't even got any useful info because some one keeps running on about safety when i DON'T HAVE A ROCKET YET HOW MAY TIMES DO I HAVE TO REPEAT MY SELF.

you dont need a fancy collage degree to make a @#$! rocket or rewire an electrical outlet

didn't read the instructions when i built my rocket also i have to go be back in a few minutes have to leave school and go get gas for truck and get home

no its not cause we actually know what where doing without reading instructions havent built or designed it yet nor tested any componet

question do any of you live in any state that is part of the southeastern united states

we have always had a lax attitude towards saftey unless it was real hazardous one time I didn't pack the parachute right and it crashed in my great uncles pasture the cow was shocked

with my dad and that's how things in the south work cause I was given a shotgun at 5 that I went hunting with my dad, hell I was in school at 5

this is a redenck low cost project and did you see how big explorer 1 was. I put it together and launched it 500ft and how many times do I have to say I am currently engineering it. no work has been done on it, very little research yet.

the goal is orbit not the present sub orbit before orbit
