At the Swedish Aeronautical Institute we perform different kinds of research, ranging from phenomenological and methodological research at a technology readiness level (TRL) of 2-4 as well as applied research with a TRL 5-7. The current research portfolio contains:

  • Tornado    

Development of a Vortex Lattice Method implementation in MATLAB,
intended for conceptual aircraft design and aeronautical education.

  •  PreCFIF-s
 Preliminary study of commercial flight in formation.
  •  P623

 Internal project on propulsion systems.


Tornado is a Vortex Lattice Method for linear aerodynamic wing design applications in conceptual aircraft design or in aeronautical education. By modelling all lifting surfaces as thin plates, Tornado can solve for most aerodynamic derivatives for a wide range of aircraft geometries. With a very high computational speed, Tornado gives the user an immediate feedback on design changes, making quantitative knowledge available earlier in the design process.
