In a shameless effort to promote the I Build Rockets website, I came up with this nifty little V2 rocket that slots together. You can download and make your own from Thingiverse

Since Cathy is both an engraver and cutter, I thought I should give it a go engraving and cutting. Layout done in CorelDraw, engraved and cut from a slab of 8mm Acrylic. Very happy with the way this turned out!

Since the arrival of Cathy - my laser cutter (Yes, it has a name, thanks to Mike!) I've been designing new and exciting things. Well, rocket stands at least!

Orbital Decay - Final test launch Print E-mail
Tuesday, 27 July 2010 10:11
After months of designing, building, testing, redesigning, rebuilding, testing, painting and more testing, the Orbital Decay had it's final test launch. My original plan was to design a good solid transition rocket. Something that you can build and fly on Mid-power but also solid and stable enough to fly it for a L1 certification flight.

This weekend's flight was on an Aerotech RMS H128 motor. The wind was blowing but not enough to cancel the day and while smaller rockets were suffering, the Orbital Decay punched a hole in the sky. Now the work begins on production.

SLAM Missile Launch Print E-mail

I presented my scratch-built SLAM Missile to the RSO at the Tripoli launch this weekend. "Where's the sim on this?" was the first question (I was armed with a printout from Rocksim) and "Where's the CP?" was the 2nd (I had marked the CP!). Lots of frowning, but it was stable. "That's going to do a loop!" but I was approved to fly it as a "head's up" launch...

The time came to press the launch button - money was changing hands at a furious pace 'How many loops will this do before it plows into the ground?'

But all went well - in fact, it was a flawless flight! Rocksim predected 1,000' on the E9. It had a good majestic boost and then coasted to apogee. The 4 second delay was perfect and recovered no more than 300' from the launch pads.

Despite the bitter cold of Melbourne's Winter, Sunday's Tripoli launch at Serpentine was a huge success! By the end of the day, 15 flyers had launched 17 rockets between them with most returning to Earth in the same condition that they left.

Karl had a super flight to achieve his Level 2 certification and received the appropriate 'Ooohs' and 'Aahhhs' from the crowd that had gathered to watch.

A new Tripoli member, Tim, had three good launches. His upscale Yankee popped a fin upon landing but his upscale 4" scratch-built Goblin put in a superb performance and came down unscathed.

Scratch-Built SLAM MissileScratch-Built SLAM MissileThis is Rocket Science SLAM MissileSome time ago, I read an article on This is Rocket Science. It talked about a crazy nuclear powered rocket and was illustrated with the image to the right:

Back in the mid 1950's, nuclear powered cruise missiles were being studied and in 1957, development was initiated as Project Pluto. The reactor for the missile was to be developed by the Lawrence Radiation Laboratory, with the ramjet being built by Marquadt. Ling-Temco-Vought was awarded the contract to develop the airframe for the missile itself, which was known as SLAM (Supersonic Low-Altitude Missile).

And I thought to myself (and anyone else in ear-shot at the time) that I had to have a go at building one!

I built this up in Rocksim. It seems stable and an E9 should push it to about 1,000' and an F21 to about 1,900'

If the weather is on our side this weekend, it should get a launch!

Orbital Decay Prototype 2The Orbital Decay had it's 1st test flight this week with a new fin design. Stability issues now fixed!

Final tweaks on the kit and it should be ready to ship early in July.

The first run will be 10 kits, but looking for a larger run on the 2nd batch.
