New Fuse Concepts
Too bad a company doesn't come out with a new line of fuses focusing less on current scale bodies but more of a futuristic idea with some believability while maintaining functionality. What would a new heli look like, say in 100 years? Assume they still use rotor systems of today's variety. Maybe a bit more NOTAR ideas or fenestron use. I wonder this because of the current full scale helis being offered. The EC's and Explorer's are a bit of a change from the past so why not look beyond that? Would the skids retract like wheels do, would sponsons provide a little more lift for ROG takeoffs, would the fuse change shape like the F-14 does when it's wings sweep???

I'm not the guy to design such a concept fuse but I'd buy into a few as long as they are believable and exotic. This would be a cool project for an aeronautical engineer student or Hollywood model designer and such. Or anyone with the patience to do so with a creative edge and some skill.

I'm pretty sure there'd be a market for something like this. Just look at some of the paint schemes on the pod and boom heli's out there. How many of you like the looks of say a Lambo or exotic Ferrari? Some very high end boats are looking pretty futuristic but being built today because the rich love the sexy designs and want to stand out.

In the past, function usually dictated the form but with today's technology, I believe that process can be reversed. So, anyone care to share some ideas? Maybe post some scetches or drawings to incite one of the manufactures to take a thought or two and run with it for our benefit?

To be honest, Ive floated this Idea a few years ago and I actually came up with a design but there wasnt to many takers. I mainly make bodies for the smaller 450 size helis and under. I myself like designing new things. I may still revisit the idea when I have more free time but it does seem people do like the existing scale bodies of what actually is out there. I like to do experimental stuff but it does take time.

I think there's definitely a market for that kind of thing, but a lot of scalers are driven by the idea of modeling a real full size heli, and it's actually a requirement if you're going to compete.

I would like to see more variety in the fuses brought out, especially in the 50 size, which seems to be taking off, and is affordable for a lot of modelers. It's kind of like ARFs with the plankers: how many different Mustangs (Ranger, MD500)do you need??

There are some pretty cool concepts out there that could make interesting models, like the Sikorsky X2

Or the FireScout

I would love to have Fire Scout though BTW, the new Fire Scout are in 4 bladed main rotor.

I would do a fire scout too. I think also there are plenty of helicopters out there that you dont see bodies for IE EH-101, S-92, H-53 and so on.B400 500T ds3400G

Hey, that looks like a Wescam under its nose.

I wasn't thinking for scale competition as much as for exhibitions and demo flights. You know, something to draw a crowd because of it's coolness factor.

I was just thinking out loud and looking for something a little different as I too love the scale birds as well. I second that FireScout idea.

Yeah, the Fire Scout has the coolness factor for sure. Let's see...how much foam do I have left?

Here's the guts of it, interesting reading.

The X2 isn't pretty but it sure is unusual. Have they gone into forward flight yet? I'm curious if it can fly past a retreating blade stall, if not then what's the purpose of it's complexity? Is the rear driven by the same engine as the rotors?

I keep imagining a UAV that has arms that double as the skids when landing. During flight, it can hover up and literally pick up objects to be relocated where ever. This would allow a rapid movement without the requirement of a ground rigger or cargo nets. The arms would shift the load either aft or forward to keep the C of G where it needs to be. Maybe even assisting with dynamic flight characteristics, i.e.- say rapid decel or turning maneuvers by shifting that C.G. point. This may allow for a much more rigid rotor system.

This comes about from having fun with this little dude. Something a friend and I made from a Walmart halloween toy a few years back.


It always made me think when I flew it nose in and it looked like it was going to pick you up and carry you off to eat you or something like that. Anyway, this is where the idea came from. Of course the UAV would be a bit smarter and less skully.

The counter-rotating rotors should mostly eliminate retreating blade stall, since you have a blade moving forward on both sides.

It will be interesting to see how the flight characteristics develop as they get more flights on it.

Piasecki X-49A SpeedHawk

Words from http://www.defensereview.com/module...rticle&sid=1061
"The Piasecki-Sikorsky X-49A Speedhawk VTDP tech demonstrator has already flown over 200 mph, albeit in a "slight descent". It accomplished this feat during a flight test on October 08, 2007. The Speedhawk achieved a speed speed of 177 knots, which translates to 203.69 mph. Not bad, but since the non-compound/standard SH-60 Sea Hawk Helicopter's top speed has been listed at 180 mph, we're guessing that a compound version utilizing the same airframe--like the Speedhawk VTDP compound helicopter, for instance--once fully-developed, will be able to fly significantly faster than that. We'll just have to see."

While this is true Rodan, you also will have two blades in a full stalled condition which may give some pretty undesirable oscillations that may trash the airframe. I suppose that with a very rigid symmetrical rotor blade that the stalled blade could be stable but only if the pitch is pretty much zero. That means that the machine would rely on other factors for lift...this is purley IMO and note that I am not an engineer of any sorts. Just seems like logic to me, for what that's worth.

Still, interesting design that I want to follow from curiosity.
