Did large winglets contribute to the spin behavior of the SB 13 tailless glider?

The SB-13 swept wing tailless beauty was developed in the early 1990s as a small recreational glider with relatively large upright winglets. The design proved very spin prone. It occurred to me ...

Any biplane flying wings after 1914?

Were any biplane flying wings built and flown after the 1912-1914 variants of the Dunne D.8? If not, why? Wikipedia mentions merely that this type was too stable and insufficiently controllable, but ...

Why are there no cargo aircraft with “flying wing” design?

From that I have seen so far, the "flying wing" design (like the one of B-2 Spirit and Northrop YB-49) has superior performance but also a few notable problems that make it difficult to use for ...

Would a pure flying wing in straight and level flight have zero wing bending stress?

In studying the NASA 247 foot wingspan solar powered Helios aircraft it seemed that evenly spacing the weight would help create a lower bending stress across its span when in flight, as gravity and ...

How do elevons work to roll a flying wing?

I have an RC Flying Wing that uses elevons for control. To go up both elevons move upwards and the wing pitches up. Both go down and the wing pitches down. I’m OK with this. However, if I want to ...

Documentation about “drag stabilized flying wings using non-reflex airfoils”?

What provides lift is the wing, but it is unstable without one stabilizer. Flying wings airfoils, or reflex airfoils, carry their stabilizer inside them, through a reversed camber of the trailing ...

Why do many stealth aircraft have a similar shape and design?

I have been playing around on a bunch of programs with stealth planes and their general shape. I know that they are required to be flat and have some sort of special material/paint on to 'absorb' the ...

For a small flying wing, can two motors with different speeds replace the ailerons?

I was thinking about a way to get rid of the aileron, and I was wondering if: I install two motors on the wing, and make the right one spin faster than the left one, will my wing roll to the left ?

For a flying wing airfoil, which AOA is to consider when selecting Cl?

I'm in the process of designing a flying wing. I'm trying to keep it a small as possible, so the lift coefficient is very crucial for me. I'm currently looking at some airfoils but most of them ...

How does a flying wing keep from going into a flat spin when maneuvering?

How do flying wings, like the B-2 Stealth bomber, actually keep themselves from yawing out of control without a vertical stabilizer? For the record, I assume this has to be a simple mechanics process....
