Awesome Video: A Rocket Launch and a Very Close Call

This rocket launch from the Friends of Amateur Rocketry (FAR) test site near Mojave, Calif., nearly wiped out the remote controlled helicopter sent aloft to film its takeoff. The rocket was launched by Paul Breed of Unreasonable Rocket on December 10. Video used by permission of Paul Breed.

Ironically, the helicopter was severely damaged later in the day in an unrelated crash.

Update on Unreasonable Rocket

An update from Paul Breed on the testing of his Unreasonable Rocket engine:

We went out to FAR and tested our H2O2 and Kerosene regen Motor.We ran it in Mon0-prop mode then in Bi-prop mode. It took a awhile to light in bi-prop mode, but We ran to about 80% throttle without damage in biprop mode. The Video does not really do it justice as it seems to have “sampling” effects. The Monolithic cat pack is clearly not getting good decomposition, probably leading to slow ignition. We need to rework the system test software so we can independently vary the proportions rather than have a fixed schedule. I have not yet reduced the data, but I’ll do that in the next 24 hours and post the result.

It was a long day and when we packed up we failed to notice a melted spot on one of the vehicle tie down straps and being tired we did not double up as we usually do. So the front strap failed and the vehicle left the truck on the dirt road leaving FAR. The road is really rough and we were going about 40mph, we did not notice the vehicle depart. We noticed it was gone and had to drive back 1.5 miles to find it. Other than a cracked mounting tab and broken fitting on top of two the small stainless spheres it was largely undamaged. We were lucky.
