Wing design
Haven’t found any answers by a search on this one.
My understanding is that swept wings are more suitable for higher speeds due to airflow considerations. Therefore I assume that most turboprop airliners don’t have swept wings because they don’t go so fast. What I am curious about is why the optimum design for wings on turboprops seems to utilise a small chord and a large span. Presumably it must be less effective to have a shorter more rectangular wing, but why?
If you consider the ERJ 145 and the SAAB 2000, which have similar Max TOW the SAAB has 4.72m more span than the ERJ.
I would appreciate it if someone could explain this to me.
Thanks.
