What stuff would you like to see from a rocket company?

[spullen]

Hello,

Wanted to start a conversation about things you'd love to see from a rocket company. I think anyone can do stuff but what kind of stuff is always the question.

 

[tfish]

Daily flights to Mars.

Sorry I should have specified model rockets.

A reloadable motor that only needs distilled water. Not a water rocket.

So maybe like a hydrogen hybrid type deal if I'm reading it right cause water on its own isn't going to produce propulsion

Yes, hydrolysis.

Are the domes built yet so we have air there?

Accurate Von Karman-shaped nose cones with fineness ratio in the 4:1 to 5:1 range, for standard tubing sizes, especially MD sizes up to 38mm, but on up to HPR sizes, that are not excessively heavy (unsuitable for LPR/MPR) or expensive.

Scale-accurate Aerobee nose cones for standard tubing sizes.

Both of those would seem to be a noteworthy hole in the marketplace, and I can't figure out why someone hasn't stepped in to fill them.

While I'm at it, scale-accurate Arcas nose cones other than the Estes PNC-55AC. Nothing against Estes, but accurate Arcas builds in other diameters would be cool.

Other than that, I think we're living in some salad days. Anything I can imagine there being a market for (and a whole lot more), there is someone offering it for sale. I still want to do a lot of custom stuff, but that's because I like creating and building stuff out of my own head. Almost all the things I want to build would be an awesome way for someone to loss their buttocks trying to commercialize.

You need daily flights to replace all the dead colonists.

4" diameter 2:1 fiberglass NC's

The Aerobee nose cones would be great. Another nose cone that there are only a few of are conicals like on several of the Black Brants

Indeed, ever since I saw (and bought) the old Estes hydrogen pop rocket I've wanted to see an actual rocket fueled by electrolysis.

I had one of those! Got tired of the D cell batteries real quick, so I found a 12vDC wall wart and 100 foot extension cord. Used to fly it in the yard. Cool blue flame at night.

A GPS tracker that will fit inside an 18mm coupler. Once that's been knocked out, a radio beacon that will fit inside an 13mm coupler, along with an electronic deployment altimeter which will also fit 13mm coupler.

18mm F (or even G) motors, 24mm H motors.

A new motor manufacturer to take up the slack in the motor shortage.

I never flew mine. I got the spare rockets Estes would send when you mailed in a coupon, but I never got around to launching it. Eventually gave it to my brother's stepson for Christmas. I don't know he ever flew it either, and who knows what became of it?

Edit to add: I really regret not flying it. Looked fun, and the concept was extremely cool.

 

[nickt.mrc]

Longer and stronger couplers and thicker centering rings and bulkheads for 29 and 38 mm tubes. I have a design for a rocket using 29 mm motor tubes for the body tube, but the available couplers are thin and only 4 in on length.

We have had 24mm H motors back in the day. Seems demand was low??

Edit: or perhaps it was quality in that length?

EditPPS: I remember 18mm E motors, I 'Think' there was also a very small F in 18mm as well. IE about 42ns , so it would count for F altitude in an 18mm rocket

They these from BMS C52H X 34"



29mm to 38mm centering rings

@Art Upton pointed out my go-to for 29mm cardboard coupler. If you need fiberglass coupler, Wildman sells it in arbitrary lengths by the inch. I see you're in the UK. I don't know if BMS offers international shipping, but Wildman does. I don't know a source of 29mm carbon fiber coupler.

I thought about mentioning cardboard coupler stock myself. I can buy it in 34" lengths from BMS for most sizes of low-power tubes, but for 38mm and 54mm high power sizes, I'm limited to 4-5".

This would be cool. That would also mean another option of motors casings for those loads.

The BMS 29mm coupler is basically centering ring stock to go from 29MMT to standard-thickness BT-50.

LOC 29mm couplers are thinner, but only come in shorter cut lengths. Still long enough for an ebay using smaller electronics, and you could always double them up to go longer if needed.

Apogee sells the thinnest couplers to go with its "thin-wall" 29mm airframe tube that is basically the same as Quest 30mm airframe (also sold as Q30mm airframe by BMS in long lengths).

Lots of options in 29mm.

In 38mm, the only option I've found is LOC. Several other companies sell cut-length couplers, but they are all LOC parts when you look into it.

I have six of the old E27Ts for the 18/20 case. They are quite old, and I've have trouble with older C-slot Blue Thunder loads shrinking and closing up the slot, so I need to get the grains out and see if they need any work. The ones I have have 4 second delays, but I'll fly them with electronics and no charge in the motor, so that won't be a problem regardless of how the rocket ends up.

Yep, there were also E single use in the same 18mm size , the F if it existed was longer I recall , but memory on that is Fuzzy

Unfortunately I missed the era of long, skinny, high impulse model-rocket sized motors. Was very excited to learn today that the G55 is coming back. It's lower impulse than the CTI G motors, but much lighter.

Why thicker centering rings? What problem are you trying to solve?
