held Friday sept 18th , about 24 people showed up .representing places like Insitu ,near space corp ,cloud cap,nwuav propulsion ,hood tech corp ,nw tech,evergreen helicopters , arcturus,Peak-Aviation and In Vitro aviation. It was held at the beautiful Hoffstadt Bluff Visitor Center near Mt St Helens in Washington .Things kicked off at 11:00 am ,Joe from NWAUV acted as mc . Joe started off talking about how the chapter is being formed etc with some informative Q&A he then talked about NWUAV and showed off their engine and models he also talked about the heavy fuel injection system they are working on for their engine line up. It uses MEMS technology originally designed by HP for printing to atomize the very hard to burn heavy fuels .After that we all stood up one by one and introduce ourselves then it was time for some mingling and lunch . After lunch the guys from Near Space did a slide show with videos on some of the high altitude uav drops they have done , we are talking 150,000 ft altitude , very cool stuff .Aram from Hood tech then spoke about hood tech and his efforts to get kids involved in robotics using lego mindstorms and of course he was very excited to hear about Chris's lego auto pilot . After that we talked more about forming the chapter ,people volunteered for the various posts and we decided on a name we picked "the Cascade chapter" although "the Sasquatch chapter" was in the running. Thing wrapped up about 4:00 then it was time for the drive home. here are some pics I took ,I really liked the variable pitch prop.
example jet cat P-80Fuel consumption: 9 oz per/min at full power for comparison I get 25 minutes of 3-D flight out of a MDS 1.25 glow engine with a 20 oz tank according to bench test it burns approx 1.667 ounces per min at full throttle .the mds puts out 18 lbs thrust and the jet puts out 17.gas is even better.hence the scan eagle uses the $20k++ engine you see pictured here . i don't think price was the issue.
Hi Wayne, I do not agree with you on the fuel consumption. A gas engine is much more fuel efficient then a piston engine. A turbo prop for example is a really nice. The only bad thing about a gas eninge is the price.
yes you do see little turbo chargers . gas turbines are very thirsty ,they go through fuel like nobody's business. nwuav also talked about using them to power generators .kinda makes sense as 2-cycles need back pressure anyway .

But why do you not use a gasturbine?
