GDSCR - Gas Dynamic Stabilization Cluster Rocket

[Rschub]

"as intended" Can we really use this term with a straight face?

I am just kidding, of course. The reason I wonder is the need for a spin can due to roll reversal on the active stabilization rocket by Jim Jarvis.

I think the gas stabilization will result in a straight up line, followed by a Lomcovák type maneuver at apogee.

@jqavins and @Rschub .... It's an exhibition, not a competition.

Please, no wagering.

LOL

Well, if the GDS works successfully, and the Lomcovák maneuver happens at apogee... the battle has been won.

This is insane…

As a wise man once said, it's an exhibition, not a battle.

I am betting on roll reversal due to the deflection of air over the pods, if anyone is keeping score.

Could be tested by a three part harness to a single cord to nose cone tip, attached to blow dryer and dangling vertically nose up. A swivel wouldn’t hurt.

If you get it right you get 1 free G.

But I’m not paying for it.

Wagering will invite only scum and villainy, turning the launch into a South East Asian style madhouse we often see on YouTube. We must stay on the straight and narrow path and not be tempted by the worldly pleasures of the dark side. PURE SCIENCE! THIS IS THE WAY.

Don't let him fool you; gravity is always free.

Not if you’re going 8kps at 150km

 

[BABAR]

I dunno. Some people experiencing misadventures involving roofs, ladders, and parachutes have found a single G to be pretty costly.

Does that mean you have to pay an orbit fee or else fly off into deep space?

 

[NTP2]

No a deorbit fee.

 

[BABAR]

No a deorbit fee.

What’s that saying about “failed parachutes”?

It’s not the fall that kills you, it’s sticking the landing?

That nosecone looks like an x-ray of my jaw. Had to get two dental implants.

YowZaa! When you build "Hell for Stout", you ain't kiddin'!

 

[Buckeye]

Now this design properly fits the description of "scratch built." Nice.

Looking forward to the flight results.

you said you are in Colorado by the Continental Divide. Hope those rain forecasts turn favorable so you can get out of the burn bans and we can see some of these birds in action!

Yep, you and me both.

Recovery Bulkhead

Using a formed metal wire from a spring clip.​

Bulkhead is 1/4" plywood, sanded down to 3/16" th., with a 3/16" hole.​

A 3/16" poplar dowel (which will be cut off once the glue dries.​

A good chute is included in the package.

Finished gluing in the bulkhead... This one's ready to fly.

After a successful flight does it get a black silhouette figure above the lunar lander on the evolutionary ladder of flight decal?

Sweet,when will you fly it?
