NFD - Nyaben Flight Dynamics

NFD is an enterprise located in Büttelborn near Frankfurt, Germany. We offer services in the field of aeronautical engineering in which we can draw upon many years of experience. Our focus is on flight simulation, parameter identification (estimation of flight mechanical parameters based on flight data), aerodynamics and flight control. One of our outstanding achievements is the development of flight dynamic models for Level 6 up to Level D Full Flight Simulators which are also suitable for Aircraft Upset Recovery Training, i.e. training for stall and spin recovery as well as unusual attitudes. Our services can be divided up into 3 main categories:

  • Engineering
  • Consulting
  • Coaching

We would also like to convince you of our capabilities. Please contact us for additional information.

Dr. Danyck Nguewo

- Owner -

Dr. Danyck Nguewo was born in Bordeaux, France in 1974. He grew up in France and in Cameroon. Dr. Nguewo studied aeronautical engineering in Kiev, Ukraine with a focus on aircraft design and construction. After receiving a doctorate in the field of flight mechanics, flight simulation and scaling laws at the University of Stuttgart, Germany, Dr. Nguewo accepted a job in the industry for a leading manufacturer of General Aviation aircraft where he was involved with the development of flight dynamic models, parameter identification, the development and validation of control algorithms for unmanned aerial vehicles, as well as the acquisition and management of research projects. From 2013 to 2015, Dr. Nguewo worked at the company’s headquarters in Vienna after moving from the German branch office in Egelsbach near Frankfurt. Dr. Nguewo has been teaching the subjects Flight Mechanics as an external tutor at the HAW in Hamburg, Germany since 2009.

Martin Winet, MSc

- External consultant, Chief Sciences Officer -

Martin Winet (born 1987 in Switzerland) graduated in 2011 in Winterthur from the Zurich University of Applied Sciences (ZHAW). His bachelor studies in aviation engineering were focused on aerodynamics and lightweight construction. After his bachelor thesis within the topic of mathematical modelling of unmanned aerial vehicles, he worked at the ZHAW as a research asssistant. He participated in various industry related and research projects in the fields of flight simulation, aerodynamic development and aircraft performance. This was followed by a master studies programme in aerospace engineering in Stockholm with specializations in flight mechanics, control theory and compressible flows. Subsequently he worked project based as an external research associate at ZHAW on the development of flight dynamic models and on aerodynamic parameter identification.

Isthelle Nguewo, MSc

- External consultant, Chief Marketing Officer -

Isthelle Nguewo (born 1982 in Yaounde, Cameroon) graduated in 2006 from the Karlsruhe University of Applied Sciences in Germany. She studied electrical engineering and automation technology.
