A different perspective

Postby air.command » Tue Sep 15, 2009 11:45 pm

Hi Guys,

We had a good flight day on Sunday with NSWRA at Doonside. We flew a modified rocket that gave us a different perspective of the rocket in flight. We were using the technique to investigate what happens inside the lowest bottle during flight. We mounted the camera on a long boom sticking out the side and looking back at the rocket and nozzle.

Here is the video of the flight: http://www.youtube.com/watch?v=Ug7k57S3XTs

And the full writeup with pictures is here:

We'll have another go at this one with a few modifications to see if we can see things a bit more clearly.

George, that idea is soooo cool. The video is so good that I had to watch it a couple of times. My favourite parts are the slow-mo of each fight.

That really is amazing.
If you had a longer boom and zoomed the camera out you could conceivably see the whole rocket (except the boom would be in view as well :roll: )

This weekend at Doonside we flew the rocket again 3 times with the camera on the boom to try to get a better shot of what is happening in the lowest bottle in flight. We used food colouring to enhance the contrast and no foaming agent this time. We also painted the fins a neutral gray to prevent the auto-iris on the camera making everything else too dark.

Here is a link to the full launch report:

or a link to the video directly:

The launch report also covers the results of some more splice testing with Sikaflex and PL premium glues.
