Pusher-in-boom Configuration

Posted (6 years 1 month 1 week 5 days 22 hours ago) and read 3098 times:

I searched 2H4's database of interesting airplanes and couldn't find one. Does anyone know of aicraft, that has a pusher configuration, except instead of having twin booms or placing the prop aft of the tail, the prop would be in front of the tail with the boom running thorugh the center.

I'm interested to see what affects the flexing of the tail would have on the prop, as well as how the prop would be connected to the engine. If my explanation isn't clear I'll post a picture of it tonight.

Thanks for you help.

Those are close, but what I'm looking for has no support to the tail besides what runs through the prop hub.

Hmm....nothing comes to mind....let me chew on that for a few days, and I'll let you know if I come up with anything. Or, very likely, someone will beat me to it and post a photo!

Thanks, I knew you'd be up to the challenge. I tried google and google Patents,, but i'm having trouble even figuring out what to call it. Good luck!

I wanted to say the Optica would be a good example but it's twin boomed.


Then I found this, the SNECMA Beetle... not a prop but a jet though. And it crashed. hrrrmmm.


I'm interested to see what 2H4 comes up with...

It's not actually an airplane. It's a GE90 eating breakfast.

The optica and snecma beetle pics are both from this webpage-
http://home.cinci.rr.com/estople/weirdair/weirdair.htm

Found it when I googled images of 'fls optica'. Looks like a valiant, if misguided french effort at VTOL.

I had to think about this one for a few minutes, but I finally thought of one, the MacCready Gossamer Swift/Bionic Bat:

Found another one! Aircraft? Check. Pusher prop? Check. Prop in centre of tail? Check.

Is actually a japanese airship concept, not a real aircraft. So... whatever.

Wow that airship certainly is unique, but the Gossamer Swift/Bionic Bat is exactly what I was talking about. I did a few searches, but its tough to find technical information on it.

AeroWeanie, do you know how the prop was connected to the "motor"?

I just checked a copy of an old article from Flight International (3/16/1985, pages 24-28). They say that the prop was belt driven. Copies of every issue of Flight International every published are available on their website http://flightglobal.com/pdfarchive/index.html
