Aerodynamic Interference between Oscillating Lifting Surfaces and Fuselage Part 2: Some Applications of Oscillating Lifting Surface Theory [PDF]

open access: yesINCAS Bulletin, 2014
This is the second article of a series that deals with the calculation of the aerodynamic unsteady forces on lifting surfaces. It presents some new important details on the lifting surface theory that performs oscillations in subsonic flow.

Prediction of Lift Coefficient for Tandem Wing Configuration or Multiple-Lifting-Surface System Using Prandtl’s Lifting-Line Theory

open access: yesInternational Journal of Aerospace Engineering, 2018
In tandem airfoil configuration or multiple-lifting-surface layouts, due to the flow interaction among their lifting surfaces, the aerodynamic characteristics can be affected by each other.

Aerodynamic Interference between Oscillating Lifting Surfaces and Fuselage Part 1: Oscillating Lifting Surfaces [PDF]

open access: yesINCAS Bulletin, 2013
This is the first of a series of articles that deal with the calculation of the aerodynamic unsteady forces on lifting surfaces (wing, empennages) in the presence of the fuselage. The aim of this work is multiple: the calculation of flutter, gust effect,

Centre of pressure parameters for the assessment of biomechanical risk in fatiguing frequency-dependent lifting activities.

open access: yesPLoS ONE, 2022
Lifting tasks, among manual material handling activities, are those mainly associated with low back pain. In recent years, several instrumental-based tools were developed to quantitatively assess the biomechanical risk during lifting activities.

Experimental and Numerical Validation of the Improved Vortex Method Applied to CP745 Marine Propeller Model

open access: yesPolish Maritime Research, 2018
The article presents a numerical analysis of the CP745 marine propeller model by means of the improved vortex method and CFD simulations. Both numerical approaches are validated experimentally by comparing with open water characteristics of the propeller.
