Hydrodynamic Assessment of Distributed Propulsion Systems for Shallow-Draft Inland Vessels

Polish Maritime Research
This study investigates the hydrodynamic performance of three distributed propulsion configurations with distinct hull shapes. The influence of duct design and hull geometry on thrust, absorbed power, and the resulting thrust-to-power ratio is explored ...

Influence of Electric Wing Tip Propulsion on the Sizing of the Vertical Stabilizer and Rudder in Preliminary Aircraft Design

Aerospace, 2023
During preliminary aircraft design, the vertical tail sizing is conventionally conducted by the use of volume coefficients. These represent a statistical approach using existing configurations’ correlating parameters, such as wing span and lever arm, to ...

Aspects of yaw control design of an aircraft with distributed electric propulsion

CEAS Aeronautical Journal, 2022
AbstractDistributed electric propulsion (DEP) offers new options in aircraft design. Besides the optimization of the wing, another area of optimization is the vertical tail plane (VTP) and yaw control. The large number of engines significantly relaxes the one-engine-inoperative (OEI) case during take-off, which is mostly the sizing case for the VTP ...
