Parametric Investigation of a Distributed Propulsion System on a Regional Aircraft

With the mandatory requirement for more efficient aircraft due to both economic and environmental purposes, academy industry are exploring new design opportunities including concepts of hybrid-electric fully electric vehicles. Within this framework, distributed propulsion is a key technology future aviation, as it allows installation theoretically indefinite number small motors. The blowing effect induced by propeller can be used improve aerodynamic performance, hence, thanks their reduced size, these motors could installed along whole span covering wing. This paper presents study devoted investigation effects on regional aircraft, computing coefficients using high-fidelity CFD simulations via RANS approach. Different diameters trust levels were analysed in climb landing conditions, applying periodic boundary conditions finite section wing, simulating an infinite rectangular goal current quantify increase with reference power off condition report data function propeller’s characteristics. objective identify propose simplified analytical formulation phase preliminary design. implementation such formula lower-fidelity tools will allow fast reliable procedures conceptual
