This research investigates the Design and CFD-based aero-structural optimization study of Bio
inspired morphing swept wing using NACA 20612 supercritical asymmetric cambered airfoil
for the Bombardier CRJ-900 morphing as a transformative approach to enhance aerodynamic
efficiency, structural performance, and flight adaptability in modern aviation. Traditional fixed-wing designs impose limitations on lift-to-drag ratio optimization, maneuverability, and mission-specific performance. To address these challenges, the study proposes a morphing wing system
that integrates compliant structures, smart materials, and distributed actuation, enabling
continuous real-time modification of key geometric parameters such as camber, twist, and span.
The system allows the wing to dynamically adapt to varying flight regimes, including takeoff,
cruise, and maneuvering conditions, thereby achieving improved aerodynamic efficiency and
reduced structural loads. Comprehensive computational fluid dynamics (CFDs) simulations and
finite element analysis (FEA) were conducted to evaluate the aerodynamic and structural
behavior of the morphing wing across multiple configurations. Results indicate a significant
reduction in drag and optimized lift distribution, leading to enhanced fuel efficiency and
extended operational range. Additionally, structural analyses confirm that the adaptive wing
maintains sufficient stiffness and load-bearing capacity while accommodating shape
transformations, minimizing the risk of aeroelastic instabilities. The research further explores
actuation strategies using lightweight smart materials, including shape memory alloys and
piezoelectric composites, coupled with distributed sensors to enable real-time feedback control
for precise shape reconfiguration. Integration of these technologies demonstrates the feasibility
of mission-adaptive wings capable of responding autonomously to environmental variations,
turbulence, and changing aerodynamic demands. By merging aerodynamic optimization with
structural resilience, the proposed morphing wing concept presents a sustainable solution for
next-generation aviation, reducing carbon emissions and operational costs while increasing
overall aircraft performance. The findings support future developments in lightweight, efficient,
and environmentally responsible aircraft architectures that can adapt dynamically to diverse
mission profiles.
