This thesis addresses the aerodynamic design of a flying wing configuration based on the bell shaped lift distribution (BSLD), with the objective of identifying a wing architecture that is aerodynamically efficient, inherently stable, controllable, and practically manufacturable. Following a reconstruction of the theoretical framework linking Prandtl’s lifting line theory to subsequent developments on the bell shaped distribution and its experimental validation, the study concentrates on defining the wing geometry required to reproduce this lift distribution in a configuration without vertical surfaces. The design process is conducted through numerical analyses employing XFoil, XFLR5, and AVL, while simultaneously accounting for both aerodynamic requirements and manufacturing constraints related to future realization via 3D printing.
Questa tesi affronta la progettazione aerodinamica di una configurazione ad ala volante basata sulla distribuzione di portanza a campana, Bell shaped lift distribution (BSLD), con l'obiettivo di identificare un'architettura alare che sia aerodinamicamente efficiente, intrinsecamente stabile, controllabile e concretamente realizzabile. Dopo una ricostruzione del quadro teorico che collega la teoria della linea portante di Prandtl ai successivi sviluppi sulla distribuzione a campana e alla sua validazione sperimentale, lo studio si concentra sulla definizione della geometria alare necessaria per riprodurre tale distribuzione in una configurazione priva di superfici verticali. Il processo di progettazione è condotto attraverso analisi numeriche impiegando Xfoil, XFLR5 e AVL, tenendo simultaneamente conto sia dei requisiti aerodinamici sia dei vincoli costruttivi legati alla futura realizzazione tramite stampa 3D.
