munirabbasi Posted December 26, 2019 Share Posted December 26, 2019 Hello propeller expertise Optimum angular relationship shown in diagram master of No #2 or No#3 with respect other slave with NO # 3 blade AT 12 O clock why the phase angle relation of No#3 Blade only with master. Any dynamic reason opposite blade of No.#1 to No #3 Munir Abbasi Quote Link to comment Share on other sites More sharing options...

"Any dynamic reason opposite blade of No.#1 to No #3" If you see optimum blade angle relationships phase angle measure opposite with No #1 blade to No #3 for example 20 degree angle lagging or leading to No#3 to No#1 blade Munir Abbasi Quote Link to comment Share on other sites More sharing options...
NATOPS1 Posted January 3, 2020 Share Posted January 3, 2020 The only explanation I can offer is the No 1 Blade is the reference blade based on the location of the pulse generator therefor it is a know location from which a measurement/ adjustment of relative position can be made during operation.
