Free, interactive tools to size a tail-sitter / VTOL or multirotor drone in minutes — trim, thrust, propeller, battery and stability. When you need production-grade CFD and aerodynamic design, I deliver it as a consulting service.
PhD mechanical engineer · 10+ years in aerodynamics, propulsion & UAVs
Drag polars, pressure & flow fields, transition and stability, ducted-fan and propeller flow, LES combustion & thermal — ANSYS Fluent / OpenFOAM.
Airfoil & wing selection, body shaping, drag reduction and trim/stability across the flight envelope for VTOL, tail-sitter and fixed-wing UAVs.
Propeller and rotor sizing, thrust/efficiency maps, motor–prop–battery matching and endurance/range optimisation.
Trim, pitch-moment balance, control authority and transition dynamics — the physics behind the free tools, taken to full fidelity.
Physics-informed / data-driven surrogate models, digital-twin frameworks and simulation acceleration for design iteration.
Clear engineering reports, test-bench correlation and design recommendations you can act on and defend.
A live, interactive workbench — no signup. Size the vehicle yourself, then bring me in for the high-fidelity CFD.
I'm Keayvan Keramati, a PhD mechanical engineer with 10+ years of cross-sector R&D in aerospace, automotive, energy and robotics. I take drone and UAV projects end-to-end — from concept and high-fidelity CFD through propulsion, control-system design, integration and validation.
Tell me about your drone and what you need — I'll reply within a couple of days.
