I was looking Northrop Firebird three view picture (here):
Bayou Renaissance Man: A new contender in the unmanned aerial vehicle stakes
Also Jay's concep has separate tails. And all new Rutan designs as well.
I did not see it in the videos, but this three view picture shows that the twin boom tails are disconnected from center from each other. I have been discussing about this, more so a week ago in Oshkosh - I have heard claims that the two booms interfere with each other and can start amplifying each other's flutter. Is that the reason why they are separate on this? Common sense would say that there would be weight savings for having the tail connected, but could somebody explain why it isn't so if it isn't so.
- What are the benefits and drawbacks of having them connected like on Adam A500 and Rutan Boomerang? Are there aerodynamic drawbacks from this?
- What are the benefits and drawbacks of having them separate like on for example in this Northrop Firebird? Any aerodynamic benefits?
