- I am by no means an expert, but I will attempt an answer.
-
- The only forward swept aircraft I have heard of is the X-29.
- It was a proof-of-concept aircraft built to prove that a
- forward swept wing could fly (at least that is what I have heard).
-
- The advantage to forward sweeping is the same as the advantage
- of backward sweeping (but it looks neater :-)), _ie._ the velocity
- perpendicular to the wing is reduced in magnitude thus delaying
- the point at which the wing encounters its critical Mach number.
-
- One major disadvantage to forward sweeping is it leads to
- dynamic instabilities, thus requiring a lot of computer control
- during flight to be implemented.
-
- Hope most of this is correct and helps.
