Fascinating thread with a lot of good info posted about this unique aircraft, especially by [USER=661]@blackkite[/USER].I know that the J7W1 Shinden was designed as an interceptor, but it's still often depicted in popular culture as being quite maneuverable and able to do tight turns. However, I am sceptical to this since it had a quite high span- and wing loading, and not a very good power loading either. In addition, the "pyramidal" wing twist scheme on each wing would have resulted in a poor Oswald factor, thus further increasing the induced drag in turns.In addition, it's not uncommon that people attribute canard aircraft good turn capabilities solely based on the fact that the canard provides an "up" force as opposed to the "down" force on the tail of a more conventional aircraft. However, this effect is rather small compared to the lift of the main wing, which on a stable canard configuration is unfortunately quite low due to the need for the canard to stall before the main wing.While I've seen estimates on speed and climb, are there any original Japanese estimates or calculations of the Shinden's performance when it comes to turns?
