Re: Why Didn't Late Generation LW Fighters Use Four Blade Props?
If I have understood a number of the contributions, there seems to have been an element of design compromise between the wider 3 bladed wooden props used on eg the Fw 190D/Ta 152 and the four bladed props on their Anglo-American competitors.
Could the realities of the late war economy also have played a role in not moving from the 3 bladed props, which by then would have been well entrenched in the German aircraft industry, whereas the introduction of 4 bladed props would have called on scarce design/tooling/ production resources? In other words, if you are producing a 3 bladed propellor which essentially does a good job, it wouldn't have been worth the disruption and extra resources needed to introduce a 4 bladed prop which might some, but not critical, advantages.
