Assessment of the Fatigue Behavior of Wings with Distributed Propulsion
Engineering ProceedingsThe integration of distributed electric propulsion into a wing significantly alters the dynamic behavior of the wing. Consequently, the loads on the wing structure in service, in particular upon transient gust and landing impact loads, change ...

Aerodynamic Investigation of an Over-the-Wing Propeller for Distributed Propulsion
2018 AIAA Aerospace Sciences Meeting, 2018 This paper addresses the aerodynamic performance and numerical modeling of over-the-wing propellers. Installing the propeller above a wing has the potential to increase wing lift-to-drag ratio, high-lift capabilities, and to reduce flyover noise. However, the prediction of its performance is difficult, since research on the aerodynamic interaction ...

Distributed propulsion for ships
, 2017 It is anticipated that using distributed electric propulsion (DEP) on conventional ships will increase the total propulsive efficiency. This is mainly due to two reasons; firstly, because the total propeller disk area can be increased. Secondly, because each propeller can be optimised for the local wake where it is operating. In this work, the benefits
