The physics behind FF Twin

TODOFinn to write sub-headline.

What we model

TODOFinn 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.

Topics to cover:
  • 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
How FF Twin's models work

TODOFinn to write.

Topics to cover:
  • 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
Multi-vehicle applicability

TODOFinn to write.

Topics to cover:
  • Multirotors
  • VTOL (hybrid quad + fixed-wing)
  • Fixed-wing
  • Rockets / unconventional platforms
