Ahsan M.

I am an Aerospace and Aeronautical Engineer with 8 years of experience in aircraft design, UAV and drone design, CAD modeling, CFD analysis, FEA, and design for manufacturing (DFM). I help you turn an aircraft concept into a detailed engineering design, assess its aerodynamic and structural performance, or refine an existing design for prototyping and manufacturing. My work connects aircraft performance, geometry, structures, and propulsion so that design decisions account for the complete system. Whether you need a specific analysis or support across several design stages, I can help with: * Aircraft, UAV & Drone Design Conceptual and detailed design for fixed-wing aircraft, multirotor drones, and VTOL platforms. This includes configuration selection, aircraft sizing, weight estimation, wing and airfoil selection, propulsion sizing, and mission performance assessment. * CAD Design & 3D Modeling Parametric part modeling, surface design, airframe geometry, internal structural layouts, assemblies, and engineering drawings. I use CATIA, SolidWorks, Fusion 360, Creo, AutoCAD, and Solid Edge to develop and refine designs around component packaging and assembly requirements. * Aerodynamic Analysis & CFD Simulation Computational fluid dynamics for external aerodynamics, airflow, lift and drag assessment, and thermal analysis. My capabilities include steady and transient simulations, heat transfer, conjugate heat transfer (CHT), and fluid–structure interaction (FSI), using ANSYS Fluent and OpenFOAM. * Structural Analysis & FEA Finite element analysis of aerospace structures and mechanical components using ANSYS Mechanical and ABAQUS. I assess stresses, deformation, and load paths to support structural improvements and weight optimization. * Aircraft Performance & Stability Aerodynamic modeling, configuration evaluation, stability assessment, and mission analysis using XFLR5, OpenVSP, DATCOM, AAA, Raymer Design Software, and MATLAB. * Propulsion Analysis Propulsion sizing, thermodynamic cycle analysis, and performance optimization using GasTurb and MATLAB, with consideration of aircraft power requirements and operating conditions. * Design for Manufacturing (DFM) Refining parts and assemblies around material selection, manufacturing processes, tolerances, fastening, and assembly access. Deliverables can include detailed CAD models, manufacturing drawings, and supporting technical documentation. * MATLAB Modeling & Engineering Automation Numerical modeling, parametric calculations, performance studies, data processing, and automation of repetitive engineering calculations using MATLAB and Excel. I pay close attention to geometry preparation, mesh quality, boundary conditions, and the interpretation of simulation results. My reports explain the assumptions, findings, and design implications so you can make informed engineering decisions. Share your concept, CAD files, or technical requirements, and I can help define the scope, required analyses, and deliverables for your project.
