    Gyro stabilization for tailwheel aircraft

    helicopters and autogyros take advantage of gyroscopic forces for stability right? I've thought much about (and watched a lot of RC freakreations on youtube) utilizing wheels or other non-typical rotating aerodynamic surfaces as lateral/directional stability a lot (plus a little stored flywheel...

    Shock Waves on Supercritical Airfoils

    Review you Prandtl-Meyer and Bernouli equations expressed in Mach numbers. Wikipedia has a pretty decent explanation actually. http://en.wikipedia.org/wiki/Mach_number

    GLARE composites

    One more thought I have had concerning GLARE - there is little difference in the construction of GLARE material and a capacitor other than one is used structurally, and the other is used to store a charge in the form of electrical energy. Could static electricity build up on the outer shell...

    GLARE composites

    Yeah, that's what I was going for, making my own. I think the beer can thing might not be a bad idea, not for an airplane, but for me to experiment on my own with small sample sizes. I'll see how that goes and maybe I'll make a model plane or a canoe if it goes well. thanks...

    Uh, anyone know if you need an autoclave?

    GLARE composites

    Interesting, Berkshire. I did not know that. I attended an EAA meeting last night, there are quite a few builders in the area, mostly Vans, some Pitts, a Cozy, and a Sonex. I also discovered I can have access to a CNC water jet, or soon a laser, for next to nothing other than materials - so...

    GLARE composites

    I'd consider using GLARE instead of foam/fiberglass sandwich composite, I think if done right a GLARE airframe could be lighter than foam composites, and I imagine a combination of metalworking and fiberglass-epoxy construction methods, if well thought out, could yield a faster build time. The...

    GLARE composites

    Can anyone share specific construction techniques using GLARE composite, such as aluminum thickness, epoxy type, glass type, radius limitations, or something else I am not thinking of? If someone were to design a new plans-built type aircraft using state of the art materials now, like GLARE...

    Limitations on Tractor/Combine Design

    ps I believe those are turboshaft props as it finally turned out. Optimal for slow vehicles. remember those crazy headers fold up into the shaft, and would likely have hinges to conform to uneven ground. Dang it, I'm doiing it again, I am thinking about it.

    Limitations on Tractor/Combine Design

    Hello I am back. Thank you all for teaching me and/or entertaining my crazy idea. I have not thought much about this since I started my new job back in August, they are keeping me plenty busy and pleasantly challenged. http://gontek.blogspot.com/ at this link to my new blog I posted a...

    Limitations on Tractor/Combine Design

    Addendum - crop dusting technology currently used has not changed since WWII for the most part. My senior year, the AIAA individual design project was based on improving crop duster technology. I started a project, but then started working full time, and never finished it. It was initially a...

    Limitations on Tractor/Combine Design

    There are remote sensing tecohologies that use satellies and remote sensing/ GIS to determine hte moisture levels in the soil. I have heard of airborne sensors that can identify crops vs weeds, and only apply the spray where it will be most utilized, instead of blanket spraying the entire field...

    Limitations on Tractor/Combine Design

    drkillroy, what you are referring to is called ground effect. It applies over land as well as water. Ground effect vehicles (GEV) can operate only in this area. I think the height above groud in which GE occurs is about half the wingspan.

    Is bigger better?

    Slugger, The farmers I have met share your sediment about the possibility of the hunting farm. My Uncle (an engineer) belonged to a hunting club, a timeshare property which is a nice cabin sleeps up to 25 in bunks on about 100 acres. They grow milo and crops for the deer to eat basically, and...

    Icebreakers

    I'm thinking something like this: Well, well, well. Now, as your management told you, my name is Matt Foley, and I am a motivational speaker! (adjust belt) Before I begin, I want to tell you a little about myself, so you'll know where I'm coming from. First off, I am 35 years old.. I am thrice...

    Icebreakers

    I just read one that gave me an idea - get everyone together for some calesthenics, only hire some actor guy to come in like Richard Simmons and be a total clown. Some people may go along for a while, but eventually, it would have to be funny. It is funny to me as I think about it - like Will...

    Icebreakers

    Although I enjoy drinking, it is definitely not a team sport, especially if not everyone at the company does it, and there is little chance that they do. Seriously though, I heard about a TBE where everybody gets a nerf blaster, they go into a room, and shoot each other with gund that fire nerf...

    Burnout

    Its never too late to learn how to fly - I say fuel the fire. A new outlook may give you a new, better perspective. I am a student pilot and I always look forward to my next flying lesson. I have found several ways to incorporate my flying experiences & lessons into my career, and I'm not...

    Limitations on Tractor/Combine Design

    Yeah, that balloon would be enormous, considering that the payload weight of your average hot air balloon is probably around 1000 lbs max. I just started a new job, so I probably won't have as much time to sit around and think about these things anymore. At least I hope not, one of the...

    Limitations on Tractor/Combine Design

    Thanks- my plan for crop damage on landing is basically to suffer the losses - but the max landing distance should be short, well under 1000 feet I think, to reduce these losses.
