Research topics

My research topics are conceptual aircraft design methodology and aircraft onboard power system simulation. Additionally -as a counterpart to the named theoretic topics- am I involved in subscale flight testing research. Most of my work is financed by NFFP5/Vinnova in collaboration with Saab Aeronautics

Currently I involved in the following research projects

  • Generic Future Fighter (GFF; subscale flight testing)
  • System simulation and analysis (FLUD/EDOC)
  • Conceptual aircraft design tool/framework develoment

Conceptual aircraft design

 Conceptual aircaft design faces nowadays with some big issues:

  • long development / live cycle times
  • melted improvement margins due to high/matured technology level
  • enlarged system complexity ("multi-roll")
  • enhanced enviromment and comfort requirements ("green aircraft")
  • hightly integrated systems (complexity, negativ cross-coupling effects)

Due to the named topics, aircraft developer have to consider and handle a lots of data already within the conceptual design phase, where different system layouts have to be benchmarked against each other.

Our research approach -together with Saab Aerospace- is the direct integration of CAD data in the conceptual design phase as well as a transition from classical "Handbook" empirical formulas towards physical-system related simulations and calculations. This allows the designer from the beginnig an close integration of all important systems and subsystems of an airplane.

Onboard power System simulation

System simulation is used for development, sizing, system analysis and certificate of new, more energy efficient onboard power system layouts of aircrafts. Here my research focus is on the Environmental Control Systems (ECS) which performs the ventilation, pressurization and cooling of an airplane. It is-after the primary flight control system-one of the most important systems and -usually behind the anti-ice system- the system with the highest power demand. System simulations are today that important as never seen before because of the technology transition from bleed air driven subsystems towards electrical driven and highly integrated subsystems. Performing the step towards the more electrical aircraft in the civil airplane industry, the industry is standing in front of a dramatically design change of this system, which has to be carefully analyzed before introduction.

Read more about this project in Energy Efficient Airplane Systems (link coming soon) or on our flight group site. More about general system simulation and our simulation software HOPSAN can be found here.


Subscale flight testing

Subscale flight testing is (again) getting more and more into the focus due to the rapid growing UAV market with the amazing fast development of MEMS (Micro Electro Mechanical Systems) sensors as well as powerful microcontroller which allow for flying platform miniaturisation and conquer new markets due to enlarge system performance and functionality.  

Subscale flight testing is an interesting method to:

  • test/evaluation of new configurations
  • low-cost aerodynamic measurements (“poor-mans wind tunnel”)
  • fast & low-cost design verification

Together with CFD analysis and water tunnel test results  the within a subscale flight testing campaign gathered results can be used in conceptual design to refine the estimated design benchmark factor and detect early critical issues in the design. An application example is the Generic Future Fighter (GFF) project. Read more about this topic on our subscale flight testing page.
