Oh, I'm entering this year. My team consists of three other very bright people ^^ but I'm the brightest haha. The team that wins would be my team so you'd know who I am then.
Oh, what do you mean? We're basically going to use 60 degrees fins because studies show that the rockets reach maximum apogee with it. Also, keep note that center of gravity must be above center of pressure and etc. Our rocket design is based on the apogee - 750 feet.
i know that stuff, but what airframe diameter, are you adding any other electronics, PML CPR or just the altimeter? What you're ejection plan is, are the eggs in there own payload bay or just in the sustainer?
The diameter of our bodytube will be 66mm because it is compatible with our nose cone. We're going to use an altimeter to measure the height. Basically, the rules state that the egg must be perpendicular to the direction of flight so we're still not sure where the egg will be. Also, we need to calculate the average wind velocity to determine that actual and closest apogee. Our strategy is to accomplish the 750 feet req then just calculate the drag for the 45s rescue package.
I am currently the youngest member of Tripoli Idaho Rocketry, I am on a team with a former NASA engineer,I have flow 6 H motors and four I motors, because of my team, i am allowed to as long as my partner's name is on the flight card as well, Rockets are a lot of fun for me, have you ever heard of the estes mosquito? I am making an 8X upscale of it, to fly on I300's and J350's TARC will be quite an experiance for me
They are both great programs, they tell you where the center of gravity is, and Rocksim tells you how high and fast your rocket will go on what motors.
I am working on a rocket right now called Incendia ( latin for fire) and it will bust the speed of sound on a G64 and up. all designed with rocksim
Yes, I we have both but I'm still toying with Rocksim because I don't know what every little box does yet. My teacher has it on her computer and I downloaded the free trial.
How would you move the CG closer to the applied force? Adding weight while using the same engine type would lower the max altitude. I'm using an E engine for 750 feet. Do you have any ideas how I can lower the CG near the applied force? Cutting the body tube in half would make the rocket have more drag and less stable. What do you think? What else is there in having a good rocket? Thanks ^^
uhhh, is it too far forward or back? if it is too far back, throw some expanding foam in the nosecone, until you get the desired CG point, if it's too far forward, you could put some foam in around the motor tube. Expanding foam is great because if you put to much, you can cut some out, or put more in!
Huh? Expanding foams? How would this lower my CG closer the the applied force? Don't we need to add actual weight to the bottom of the rocket? Foams are pretty lightweight material I think. Can you explain this to me a bit futher? Thanks :)

do you have Rocksim, or Spacecad.

There is a type of expandin foam, I belive you can order it off PML, and you can mix in just about anything to add a little weight.
I usually use epoxie or if i need quite a bit i use Bb's. It sounds very hillbilly, i know, but it works
AerotechMan101 3 years ago
Hm. I should look into that. I wonder if the high-school in my area has a team.
