Aerospace/Aviation/Fieseler Fi 103 (Vergeltungswaffe)
Hello: I just watched a short Youtube video ( www.youtube.com/watch?v=QY308O42Ur4 ) on the V-1 Flying bomb deployed by the Nazis in WW2.The video described the weapon as capable of a 400 mph cruise speed,which was slow enough to be intercepted by piston engined fighters.Would swept wings have given it a higher cruising speed? Thanks!
I would venture to say that even at altitude 400mph is under the critical Mach number for the V-1 and hence sweeping the wings would not provide much (if any) benefit. Swept wings are designed to enable a vehicle to approach a flight speed of Mach one without encountering (or minimizing) locally supersonic flow (and hence reducing wave drag).
There are other reasons for sweeping wings, but reduction of wave drag is primary..
