... An integrated propulsor has a strong interaction with the flow over the stem and prevents that flow from separating as it would in the absence of the propulsor. Traditional propulsor design procedures based upon interaction coefficients are inadequate for this type of application. A logical...

This paper describes the approach to integrate MIT-PSF and NASTRAN computer codes to iteratively determine blade loading and deflection during steady backing operations and the modification of MIT-PSF code to account for flow separation during steady crashback operations. The computed results...
