For all of you power hogs out there, here's an upscale of Buzz Nau's Cluros Mk II that I hope everyone likes...

The RKT file is very simplistic, no special features included, and probably will need some adjusting before a full working model can be constructed. However, I put this out to the forum for study (and drooling...).

The power is a pair of Ellis Mountain L330s. The deployment needs to be set by time, and not by altitude, as the rocket will travel into an unsafe Dv range if set strictly for max altitude deployment. The simulation I'm giving has deployment at 30 seconds after ignition, which allows 2 seconds before apogee. This gives me a less-than-2-FPS Dv. Nice and gentle for a model this size...

Length -- 139"
Weight -- 327.3 oz (w/motors)
Fin Span -- 28.8"
Diameter -- 5.54"

This has not been sent to BARCLONE yet.

Enjoy!

The original Triton design (three-stage, all 18mm motors) left a lot to be desired in the full-house configuration. There simply was not enough power in an 18mm motor to lift the stack to a reasonable height, nor was there enough final acceleration to reach a safe flight velocity without the use of a very tall tower.

This revised version has better performance in the full-house stack. The first booster has been slightly enlarged to accept a 24mm "D" or "C" motor. All of the simulated flights in the RKT file reach flight V in the length of a 48" rod; the "C" booster stack reaches flight V in 37", and the "D" booster stacks reach flight V in 34". Use the 48" rod for safety.

From 13mm "mini" to 18mm "midi," just because the lines of Craig's "Mini-Loader" are cool...

...but I wanted a bigger version, since that's what I already had parts for!

Additionally, the "logo" symbol contains an electronic music joke. "MIDI" stands for "Musical Instrument Digital Interface," and the circle off to the left of the name represents the business end of a MIDI plug. (the sound of illumination dawning)

I had to make up a similar decal for this one anyway:

A tip of the hat to you, Craig!


Cheers,

As Bill E would agree, "I'm touched"...

I like the upscale. And yes, I understand the reference. My first computer was the Commodore 64, and that was often used as a MIDI controller.

I might have to "upscale" the ML even more with some of Carl's large-diameter tubing...

This design will get sent to my growing PDF queue. Your RKT file and a 3D image will get posted to BARCLONE at the next update cycle.

Your simulation numbers are great! Those are some awesome deployment Vs for a payload model.

One more in the "todo" pile...

*Maxi*-Loader?

--Jay

Yes, with another even-larger upscale being called the "Mega Loader"...

To be quickly followed by a Goony called the Diaper Loader...

Craig, I've been wanting to knock one of these out for awhile and finally threw one together last night. I changed the design a bit. I used an old Apogee BT-20 nose cone and T-520 plastic transition. Cool design.

Looks good! Yours is farther along than mine - the plan has been out on the website since 2003, and I just this week got the parts to build it...

I'm sooo slooow these days; must be getting old...
