Thanks for the offer. Still probably won't happen, but I'll keep it in mind.
As an aside, I think the NAR should develop a program for the Teachers, before they ever attempt to teach skills that they, themselves, do not possess.
Frankly, I'd like to see an Event at the TARC Finals, where the Teachers & Mentors "square-off" and fly their own designs against each other, under the TARC rules . . . The kids would LOVE it !

I should think it would be interesting if the 'local' hotshots from NAR/TRA were involved in a 'friendly competition' to build/fly rockets to TARC requirements* , just so everyone could see what is involved.
*okay so maybe the 'adults' should build to meet a previous set of rules, 2015 perhaps.

how to clear the meeting of rocketeers(well most of them) fire up a rocket design software and challenge the 'old timers' to design a rocket w/o using paper and pencil...
Rex
I don’t know if I qualify as oldtimer (I’m 54, first built rockets in the early 70s) but I sim the crap out of everything.
We went to the Moon 10 times in those days . . . Since the advent of modern computers, we have remained stuck in LEO and, at present, we have no manned capability of our own, at all.
but I am saying that the have made us lazy and that we have become dependent on them, to our detriment.
I've already lined up a "Rocksim Guru" to enter the data I supply. It will be interesting to see whose predictions are more accurate !
Meaningless comparison. No correlation.
Utterly ridiculous comment. Computers and simulations made us smarter, safer, and cost-effective. Life is better.
Please share your differential equations solved by hand. Sorry, Rocksim will always be more accurate.
For a guy who has a tag line of "Adapt and Overcome," you are sure stuck in the past.
Cool! This is how I "Sim" my rockets also!!! I find the correct equations, work with them by hand and fully understand them. Then use something simple like Excel, because once you have the math, you have it.Buckeye,
Unlike you, I am unwilling to "blow up" the OP's thread . . .
Did you ever stop to think how equations were solved before the advent of calculators and computers ?

You realize that this is in fact a hobby, right? That people do for fun?I always figured that if someone doesn't understand the math behind rocket science, then they are not rocket scientist and just hobby flyers looking for the easy way out...

Then why disparage those who enjoy it in a different way from you?Yes it's an awesome hobby that has all kinds of people in it and something for everyone!!!

That's fine, you do you. However, complaining that computers or calculators have made us lazy and stupid is tiresome. The same could be said (and has been, pretty much) about every automation and/or productivity-enhancing tool that's ever been invented. Society evolves.Personally, I enjoy the mental challenge, as I feel "BLH" does also, of doing the calculations manually. In my case, it does not stem from a "distrust" of technology but, rather, from the position of being thankful that I am not a "slave to technology", relying on it, rather than my own abilities.

In any case, this discussion has zip squat to do with TARC teams, unless you expect middle-schoolers to solve those equations before they fly a rocket. Let's move on.
Of course not. You were merely ranting off-topic in post #44 that them there fancy new-fangled computer thingamajigs killed the space program and made us all dumb.
Great work on your Math 201 homework! Professor Buckeye gives you an A+! Now, for the final exam, please solve the realistic equations of rocket motion, in multiple degrees of freedom, with varying mass, thrust, drag, and air density. Take all the time, paper, and pencils you need....
They did indeed. However, they only got 3/4 screwed... they did after all get to build rockets, to get a little taste. My friend's daughter might yet have a chance to fly hers and try to qualify. A trip to the nationals is obviously not gonna be happening, but that's OK.This team of kids got screwed, in many ways. Their teacher has no expertise in Rocketry. The design is terrible. They are out of time. I feel sorry for them . . . They deserved better than this !
