Water Rocket Car MkX – Launch Day

The Easter break allowed a chance to actually do some work on the water rocket car and to upgrade the car to test some stability ideas we have been working on. These include

– outrigger rear wheels
– rear wheels rear of the nozzle
– larger rear wing
– bottle alignment guides

All of these design changes added a bit of weight to the car but we wanted to test for stability rather than just increase distance. What we were after was a straighter launch

We also had a small update to the launcher with the addition of a 20L container to hold 20L of water to hold the launcher down and reduce recoil. It also doubles as a good water supply for rocket fuel :)

Here is the video of the launch day

The longest distance recorded was 87m but that was uphill so over 100m on the flat isnt too much trouble even with the extra weight. We were happy with the results of the stability upgrades with the last 120psi run going straight up the middle of the road.

We will do some more work on this model before we build the next one, there are a few more things to test yet. Hopefully the next update wont take soo long
