• Hands-on CFD and FEA tool experience with validation.
• Experience with turbulence models and wing design.
• Proficient in scripting/automation with Python or MATLAB.
• Familiarity with certification-related documentation (DGCA/defence).

Responsibilities

• Perform advanced CFD using ANSYS Fluent and ANSYS CFX.
• Conduct structural and nodal analysis using ANSYS Mechanical.
• Analyse lift, drag, induced drag, flow separation, wake and vortex behaviour.
• Model multirotor aerodynamics, VTOL transition and fixed-wing performance.
• Apply turbulence models: k-ω SST, k-ε, LES.
• Execute high-quality meshing, grid independence and convergence studies.
• Design and optimise airfoils, wing geometries, UAV configurations (L/D, endurance, payload).
• Perform parametric studies and iterative optimisation.
• Support FSI and coupled simulations.
• Correlate CFD/FEA results with flight test data.
• Prepare aerodynamic & CFD reports, FEA/structural validation reports.
• Support type certification and compliance documentation.
