How do I account for propeller overhang when constructing a static alignment or lateral vibration model ?
The overhang of the propeller is produced by inserting a shaft element between the propeller and the aft end of the tail shaft. This element should have a length that is equal to the distance from the aft end of the propeller shaft to the centroid of the propeller, a density of zero (0), an outside diameter approximately equal to the propeller hub diameter, and an inside diameter of zero (0). The default elastic modulus for steel is sufficient (2.07 Gpa). Other alternative methods can also be used. Please contact SML if you require further information.
