Tidy up

Hey Guys,

Its been a while since I did anything let alone the data recording side of everything.

So today although I'm still away from home at the moment I thought I'd do some housekeeping on our data records and thought id share a picture or two of them.

I am aware its not the most exciting post in the world, but the plan is I'm going to continue work on updating the launcher as soon as I'm back in the UK. I have been saying this for a while with no posted evidence of it, but I assure you work has started on it, posts have just not been composed in a while but that fact will change as soon as I return.

Apologies again for the less than interesting post, i hope some could read and not be bored stiff.

Quick Post (First of 6 Parachutes)

Hey guys,

I have began to make a few of the previously mentioned Parachutes beginning with one of the 75cm diameter chutes. The chutes are made with a thin but very durable rip stop nylon cloth I bought online.

   I still have yet to start planned work to the launcher allowing it to take a release head for larger nozzles. I plan to start work on it sometime in the coming week and again will be posting the progress regularly.

Until then thank you for reading this short post, i shall be back with more  A.S.A.P.

Merry Christmas Everyone!!

Merry Christmas All!!!

I hope everyone has or will enjoy there Christmas Day   .. :)

(Stratum I) Plus a few odd's and end's

As mentioned previously I have been working on our first series of rockets to use multiple spliced pairs joined with tornado couplings.

I have just finished making the fin set we are to use on this series, which in this case was the last piece of the puzzle and the rocket is now complete.

All the rockets STATS are displayed in the Visio drawing below:

As seen above we plan to make a more streamlined nose cone/deployment system for our rockets, this is something we hope to start on during the winter as well as some planned improvements to the launcher. 

The improvements made will be to allow us to change the release heads for larger or smaller nozzles however the case may be, this will be done with a permanently plumbed in copper tube system.

I have also hollowed out a few of our tornado couplings  and placed the seals kindly provided by George over at Air Command.

PARACHUTES!!

We have always used 2 small 20inch anti tangle chutes on our rockets these now however are much to small for the weight our rockets are gaining, therefore I have bought a large amount of thin Ripstop Nylon to make parachutes with. 

The plan is to make 2 of each sizes consisting of 75cm, 1m and 1.5m diameter parachutes. 

I have now started the Blog I mentioned previously about a traction engine build if anyone is interested. http://modelengineeringpursuits.blogspot.com/

Thank you for Reading

Three New Splices Finally Finished

Veteran Fracture II Vessel serves as Strapping Tape Key

I finally got round to finishing three splices I had started almost the day after our last launch, all the splices have been pressure tested to 160PSI, 20PSI over there launch pressure and held there for 5 minutes before the pressure is released.

The New Three Splices

Two of these are going to be put to immediate use to make Stratum I (6.8 Litre Rocket) as mentioned in a previous post this will be our first rocket to use tornado couplings. More splices now however will be produced as spares and backups in case of a CATO  or Crash that may occur.

A Sneak Peak of Stratum III the Largest Rocket Planned to Date the Vessel Currently Stands at  224cm (7ft 4in)

Between me and the rest of the crew we have decided to not launch any of the Stratum assemblies until we have carried out a few further flights and feel comfortable with the Robinson coupled Nexus series.

Waiting to launch Stratum will also give us chance to give jet foaming a go, something we've been meaning to try since the assembly of Nexus I nearly 2 years ago!!
