Troy Hartman tells us more about his jetpack.
50% throttle yielded a speed of 47 mph. A second set of test runs demonstrated ascents of black diamond rated slopes.
“The Personal Jetpack was a bit of an accidental creation that stemmed from the development of my Jet Wing (similar to that of Yves Rossy). The engines I am using are designed for use in Unmanned Aerial Vehicle (UAV) applications, and are thus massive at twice the thrust of those used by Yves. I was losing sleep at night thinking about these monsters screaming at 100,000 RPM and 1500 degrees F only inches away from my skin. I decided I needed to build a testbed that I could wear on my back. This turned into a much more involved project than I had envisioned, as I realized how difficult it was going to be to cram all of the necessary systems into a small space, and make it wearable. I figured if I was going to put this much effort into it, I may as well trick it out! The final result was a fairly compact jet backpack of my own design. The first test fire-up was frightening to say the least, but successful.”
