Am working towards another section of the plane and wanting to know the closest distance any structures could be to propeller blades , 2 blades or 3 blades ??
Is a close structure influenced in any way as the tip of the blade passes it !!vibration ? , noise ? and with two blades do you get harmonics as the 2 blades pass a structure on either side in the same place ??
