Just wanted to release to you guys the first pictures of the latest UAV helicopter I have designed and built here in China. It is now being packed up and sent to the UAV show in Beijing, lasting Oct 20 through 25. I'll be there to answer any questions.
This helicopter is called the Flying Tiger, and it's bases off my Star-Lite series UAV that I few some years ago. However, this version is powered by a 582 Rotax with a new PEP exhaust system I just built for it, pumping out 78hp. This baby can pick up 440 pounds of payload and fuel. It also has all new transmissions, blades and frame. Every part for this aircraft is special designed and built by me, and was no small job doing it all here in China.
It also has a new style rotorhead built especially for high speed and stability, utilizing a combination double-separated double-teetering system that has the stability of a fully articulated system and the simplicity of a two-bladed teetering system. I also came up with a way that virtually eliminates the rotor systems Coriolis effect, but still using a simple elastomer damper system to handle the deferential airspeeds between the four rotors during forward flight. I also was able to come up with a modified control system that can control from 2 blades up to 6, which is much advanced from my old Mini-500 system. The new system is under patent pending.
Flight testing will begin sometime after we return from the Beijing show.
I'm in a hurry now to get it to the show, so I'll post more internal pictures later. Enjoy.
