H999 contest

I think I could devise a scheme to keep the shell intact. No guarantees on contents, but I bet I could keep the shells just fine.

ditto, and I’d go a step further and suggest the yolk might be kept intact as well, all depends on the weight of the rocket and the means used to cradle the egg. Using something like an apogee egg capsule would not cut it. You need a serious suspension here IMHO.

I wouldn’t use a brick. That defeats the purpose of the competition 😀

Use a small, light rocket. Make it a 100g egg 😀

THAT would be a challenge to keep from scrambling 😆

Actually, I have been talking with some ole bioengineering alumni pals now at Genentech who promise they can make chickens lay bricks with a little gen engr and the right diet–mostly CaOH which they like anyway, and aramid precursors, that an acquired taste but Dr Shockley has some big bipolar transistors that seem to have resulted in signif behavioral mods. The hens seem a bit frazzled, but the new androgen implants keep the roosters drilling….We think these golden eggs will survive 60 gees. Working on a 100 but it may take a generation or two…

I was thinking some sort of fluid or gel suspension system could do the trick…

I’m thinking a form of suspension too. That seems like the best bet for keeping the exterior of the egg at least from breaking. Not sure what would be best though…

Yes, green jello is an option, neutral buoyancy fluids such as mineral oil maybe salt water, etc, but I think it needs to be a spring loaded sled as well, maybe more. At least 2 time constants in the system for sure.

I will admit that the more you guys talk about this, the more I think about this challenge. I wasn’t talking about jello necessarily, but something like a mineral oil filled payload bay. The egg will float in mineral oil (5W50 is what I’m thinking) and if done right, thrust will push it down in the oil, but the oil will slowly flow around the egg cushioning the impact shock of the fast burn motor.

By the way, I’m thinking we should do this like the Single Shot Sweepstakes – pick a single motor and use it as the core rule. The H999 is what I’m thinking… any comments?

I like it. Fastest H motor ever made, and not likely to be dethroned soon. Should give eggs a nice ride 😀

Note, however, that if the egg will float in mineral oil, it will not be pushed downwards when it lifts off. It will continue to float as the mineral oil is drawn down harder than the egg.

[Warren B. MusselmanModerator]

I’m surprised at you Chris – floatation only will occur at rest – the egg as a unit will sink under thrust. I was guessing it would float – ideally there will be neutral boyancy. I sense an experiment on whether eggs float in motor oil or mineral oil or water. I can see a payload bay lined with a plastic bag full of some vicous but not too viscous liquid or gel with the egg(s) floating in the fluid..

Another substance that comes to mind is KY Jelly…

So what is the point of this? Just flying without scrambling the egg doesn’t seem to be enough… Should it be maximum altitude without scrambling the egg? Maximum parachute duration? Nearest landing to the pad or some kind of marker? Highest acceleration?
