punkymcpunk Posted October 19, 2006 Share Posted October 19, 2006 well, for my ITD (industrial Technology and Design) assignment, we are to create a CO2 dragster, (if you need more info on what they are, just google it or something), but for those of you who do know what they are, here is an image of the design i am planning to create, any feed back would be really handy so i know what i can fix up or add to it to make it the best in the class... and just so you know i am only in grade 10 feedback?

Kiriyama Posted October 19, 2006 Share Posted October 19, 2006 The way it looks. Try to make it more aerodynamic. Denizen of Darkness| PSN= sworddude198 Link to comment Share on other sites More sharing options...
punkymcpunk Posted October 19, 2006 Author Share Posted October 19, 2006 how do you mean? Anybody wanna sell me a discount whip?50 barrows runs and still no drops, I'm thinking it doesn't like me... :( Link to comment Share on other sites More sharing options...
Kiriyama Posted October 19, 2006 Share Posted October 19, 2006 Well assuming the top design is the car. It is too rounded, make it look a bit more sharper. Denizen of Darkness| PSN= sworddude198 Link to comment Share on other sites More sharing options...
Lionheart_0 Posted October 19, 2006 Share Posted October 19, 2006 Are you actually gonna race that thing? If its the same CO2 car i made in grade 9, then i would suggest a design that is more arodynamic, ie. put mor bumps and curves on it to make it have more eddies, which make it faster. Also make sure there are no pointed edges. Actually, from the side view it looks fine, just make sure to kep the pointed edges to a minimum. Sig by IkuraiYour Guide to Posting!

Bmms Posted October 19, 2006 Share Posted October 19, 2006 looks good dont know if the middle will be that strong tho Aefx(started 11/1/2002) Cb: 200 TS: 1900+Bmms--Jr(Started on 1/24/06)(Banned 11/13/09 ) Cb: 119(pre-eoc) TS: 1700+Bmms(Started 8/?/2001)(Banned 1/24/06 ) Cb: 101(pre-eoc) TS: 1350+ Link to comment Share on other sites More sharing options...
indy500fan Posted October 19, 2006 Share Posted October 19, 2006 From what I noticed of the other classes that did this (I didn't get too :( ) is that aerodynamics didn't really make that much of a difference. Worry mostly about making it strong enough, and light. And make sure it drives straight. Link to comment Share on other sites More sharing options...
Tigra00 Posted October 19, 2006 Share Posted October 19, 2006 I had fun doing these in like 8th grade. It looks good, but more than anything, just make sure it goes straight. :P We built bridges (not to scale :P) in shop class too, and mine could be stood on without breaking...I think the strongest one, a friend of mines, held about 350 pounds of pressure before snapping in the little machine. Mine was like 200-ish. All that from balsa wood and some wood glue. :P The popularity of any given religion today depends on the victories of the wars they fought in the past. - Me!

Cloaked_Shadow Posted October 19, 2006 Share Posted October 19, 2006 Add a little nook for the back wheels so that the disrupted air from the front wheels don't mess with it's rotation. Also, fins can help by giving it downforce, and that will keep it from flying up and off the track. The middle doesn't look like it will hold out. One twist on the track and SNAP! Keep the front sharp, so that the vehicle can cut it's way through the air. ... Link to comment Share on other sites More sharing options...
punkymcpunk Posted October 20, 2006 Author Share Posted October 20, 2006 i'll get a 'perspective view' drawing of it soon and post that here, and if your wondering about the middle being weak, dont be, its a peice of 4mm wire holding the 2 peices together... when i make it i will might try to get the fronts of both peices to a point, but this is just a rough idea that i wanted feedback from... but thanks for what you guys have given me so far, and aswell the crosses are for the axle holes (for those who dont know) and there are smoothed out wheel arches covering all the wheels which will leave about 2mm for the wheel to freespin in, and dont worry about it not going straight, 90% of the time these things dont touch the ground...and we have to have a peice of fishing line going through eyelets somewhere on it to keep it down and going straight... i'll get to work on that perspective drawing...

punkymcpunk Posted October 20, 2006 Author Share Posted October 20, 2006 its bodgey i know, but its a 2 second job of what could be something special.... if you want a really good job do it your self... but anyway A CHALLENGE FOR THOSE WITH A GRAPHICS PROGRAM!!! OK for those who have rhino, or something like that, im putting out a challange to you to try and create this dragster or anything of your own in that program, winners will get, well, my appreciation and my thanks because it will help me out a hell of a lot for the actuall making of this car... HAVE FUN!!!! Anybody wanna sell me a discount whip?50 barrows runs and still no drops, I'm thinking it doesn't like me... :( Link to comment Share on other sites More sharing options...
Kryptic Posted October 20, 2006 Share Posted October 20, 2006 I remember making those in highschool. A girl in my class had one that was as thin as yours and hers ended up snapping in the middle. Good luck (PPPPSSSSST, maybe you should take your names out of the picture) In Khazakstan we say God, Man, Horse, Dog, then Woman, Rat and small cockroach..M.A.D 4 Lyfe Link to comment Share on other sites More sharing options...
foolgool Posted October 20, 2006 Share Posted October 20, 2006 I'd advise making the middle part juuuuust a bit wider. Plenty of people in my class had theirs snap like that. Also, make the back a bit smaller, because its a little unwieldy right now, from the looks of it. The code in my sig should say 1032 not 0132.

punkymcpunk Posted October 20, 2006 Author Share Posted October 20, 2006 and if your wondering about the middle being weak, dont be, its a peice of 4mm wire holding the 2 peices together... dont worry, the problem is sorted...
