Re: Demolition of Space Shuttle Launch Pad 39-B

I was just up close to this pad yesterday :)

Spent three days at KSC so far, and another half a day today will be the end of it for me. Lots to see.

Re: SpaceX details its plans for landing 3 Falcon Heavy boosters

Can't wait for this to go. I hope the FH goes in the first half of the month, as that is when I'll be there. Serendipity is a wonderful thing. I am being sent there for a conference by work :) . The universe usually doesn't work like that. I will get there for the Zuma launch on 4th January. I will ...

This would be a good candidate for flash-pan ignition :shock:

Re: SpaceX details its plans for landing 3 Falcon Heavy boosters

The good news about this is that I am being sent to Florida for some work in early January. Depending on timing I just might get to see this one fly 8) 8) 8) 8) 8) 8)

I am hanging out for the date to firm up (FH launch that is).

Serendipity is a wonderful thing sometimes...

Re: Devilish Project (Go Devil 38 kit bash)

Thanks for the post with the info. Nice. What was the launch mass, sans motor for the rocket? I will be using thin-wall f/g tubing, but I will be shaving off mass wherever possible. Might not make it as far along as "Mach Madness", as I am starting from some heavier components (NC and airf...

Re: Devilish Project (Go Devil 38 kit bash)

I don't have the luxury of a 7:1 VK, but it really matters how much I bash the kit as to what I end up with :D It is already significantly different. Only some of the parts are a starting point. The intent is to think about a few things along the way and then do the same thing, but better, to the 54...

Re: Devilish Project (Go Devil 38 kit bash)

Thanks for the post Sumo. Yep. They are the sort of numbers I am looking at, so far only in rough terms. That is the motor I am leaning towards currently. Decisions will be refined as the build progresses. I will try to look up the rocket in that video, "Mach Madness" and see what I can le...

Rotary Tool on Special at Hobby King

Not sure how the quality stacks up against a Dremel, but the price is right! hk170-230.jpg https://hobbyking.com/en_us/160w-dremel-style-rotary-hand-tool-w-33pc-set-230v.html I have usually had no problems with HK stuff in the past. I would buy one but I just bought a Dremel before this special came...

Re: Devilish Project (Go Devil 38 kit bash)

Fantastic info there Drew. Thanks for sharing. I am trying to get a feel for what I can do in 38mm. Orange revolution (54mm) got Mach 1.8 but I didn't put any special effort into that one, and the motor was a bit mid-range as well. I think I have come up with some cleverness for the deployment charg...

Re: basalt fibre - new material for me

Yep. Some point on the leading edge sets up a strong shock wave, which is only a few micron thick. Everything behind that shock cone sees a greatly reduced velocity and pressure. That shock wave exists as a cone around the point(s) generating it. The angle of the cone is Sine(theta) = 1/ M, where at...

Re: Devilish Project (Go Devil 38 kit bash)

I won't know till I give it a go! The design will evolve as I progress. Now the motor mount is integrated with the avionics bay I can shorten the lower airframe :) . The couplers are of significant mass too. I am looking at shaving them down a little on the inside to lighten the load a little. Elect...

Minimalist Tendencies

Motor Mount I am really trying to get mass out of this thing. I want speed! I had been thinking about the motor mount for quite a while and in the end I had a bit of an epiphany. So, a new motor mount was born. An offcut of the same fin CF material was roughly chucked in the mill and a disk was cut...
