Delta Blimp Idea

[hiflier]

Hello All,

It's a long story but I'm here because of some research I'm involved in. An internet search got me here. I have an idea that's been in my brain for over a year and I would like to open a discussion on it. My research somehow found the Black Triangle thread in the Humor Forum and CHELLIE's post. For some background perhaps you could look at the thread then afterwards maybe we could then pick it up here

I'm new here so be patient.

Hello All,

This is the concept for the main drive:



This photo is only to illustrate the idea. My mental image is to apply the ducted fan to a black triangular design fo a blimp. A year ago I picked up a small Blade hilo to study the idea. I would like some feedback on externally ducting the project like in the photo or internally ducting like I've been dreaming about. I've never built anything in the way of rc stuff but in the 1950's my father built and flew the old balsa models. Gas engines, wooden propellers and control wires as rc was not around then that I know of.

The photo posted in the second post looks like the Avro Car. Neat looking machine.

I've always tossed around the idea of the Focke Wulf vtol, although it would be complex and difficult to build reasonably scale. The small thrust outlets would probably have to be small pusher props, and who knows if it could ever transition and control reasonably with the ailerons. Always liked the look of the craft itself though:

Hello All,

Really great links. Generally I see various design ideas incorporating my Blade cx2's concept. Counter-prop engineering. That concept is fine but what I also see is that the prop uses brute strength for lift. The delta blimp will not. The counter-prop design I've had in mind is completely internal with no exposed machinery at all- just vents along the edges. If I have the where-with-all I'll sketch it out, scan it, and post the configuration I'm trying to convey. I envision no visible moving parts, a quiet operational noise level, and by not having an open duct design better control over the altitude. Motor(s) will be for mostly horizontal vectoring. Thanks a mil for the links though, some of the motor designs are encouraging.
