Lift Off

I spent a little while this weekend making a compressed air rocket launcher. I’ve had a stomp rocket for quite a while but this was something that I used to have but lost in time gone by. So, for about a year or so I’ve been thinking of making a new one. The first of these I created after a week’s training at the Kennedy Space Centre in Florida. There I got simple plans and used them with parts that I suspect I carried on a motorbike although how I got the tubing home I don’t know. There are photos of this somewhere, but I’ve had a quick look and couldn’t find them.

Here are most of the bits I bought.

These need to be put together using the compression joints.

The trickiest part of this build is drilling the end plate so that the car tyre valve fits it snuggly. Once you’ve spent a little time you get this wonderment:

Once the tyre valve is fitted you get a beast that looks like this:

I don’t have any video yet, I will endeavour to get some ready and will add it to this page or my YouTube area.

I pumped the tube up to about 4 Bar and then opened the gas tap. I reckon I got about 5 seconds of flight time. I’m happy with that. I don’t really want to increase the pressure too much because I don’t want the thing to blow itself apart and kill someone!
