The physics behind FF Twin
TODO — Finn to write sub-headline.
TODO — Finn to write. Reader may be a CTO or senior engineer — technically literate but not an aerodynamics specialist. Avoid assuming knowledge of helicopter theory or inflow physics.
- Dynamic inflow theory (basics, accessible explanation)
- Why total energy consumption is not enough
- The three components of UAV power consumption (induced, profile, parasitic)
- Why propeller-to-propeller interference matters
- Why fixed-wing and multirotor behave differently in this regard
TODO — Finn to write.
- What makes the FF Twin approach different from generic CFD tools like Ansys
- What assumptions are safe to make for UAVs without losing accuracy
- How mission parameters translate to aerodynamic requirements
- What the optimisation algorithm actually does
TODO — Finn to write.
- Multirotors
- VTOL (hybrid quad + fixed-wing)
- Fixed-wing
- Rockets / unconventional platforms
