    • The Risk Observatory: Developing an Aviation Safety Information Sharing Platform in Europe 

      Verstraeten, J.; Baren, G.B. van; Wever, R. (Macrothink Institute, 2016-12)
      In Europe the accident rate in commercial aviation has stagnated at around 40 accidents per ten million flights: forty times higher than Europe’s ambition. Currently safety management is done per organisation, focusing on ...
    • Braking Capabilities on Flooded Runways: Flight Test Results Obtained with a Business Jet 

      Es, G.W.H. van (AIAA, 2017)
      Statistics show that the likelihood of a runway excursion during takeoff or landing is much higher on flooded runways than on dry runways. Extreme loss of tyre braking can occur during rejected takeoffs and landings on ...
    • Stopping performance flight test on a flooded runway 

      Tump, R.S.; Mulder, T.J. (Society of Experimental Test Pilots, 2017-07)
      One of the identified solutions for runway excursions is the research into the “Impact of fluid contaminants of varying depth on aircraft stopping performance”. For this, NLR has carried out water-pond flight testing with ...
    • NLR’s experience with flight testing on wet and flooded runways 

      Es, G.W.H. van; Koks, P. (Society of Flight Test Engineers, 2017-09)
      Braking performance of aircraft is affected whenever a runway is wet or flooded. Aircraft manufacturers do wet runway braking tests during the certification of a civil transport aircraft. These are normally limited to tests ...
    • A clustered and surrogate-based MDA use case for MDO scenarios in AGILE project 

      Lefebre, T.; Bartoli, N.; Dubreuil, S.; Panzeri, M.; Lombardi, R.; Lammen, W.F.; Mengmeng, Z.; Gent, I. van; Ciampa, P.D. (AIAA, 2018)
      In this paper methodological investigations regarding an innovative Multidisciplinary Design and Optimization (MDO) approach for conceptual aircraft design are presented. These research activities are part of the ongoing ...
    • Learning curve: interpreting the results of four years of safety culture surveys 

      Kirwan, B.; Reader, T.; Parand, A.; Kennedy, R.; Bieder, C.; Balk, A. (Flight Safety Foundation, 2018-12)
      Safety culture is seen as a pillar of aviation safety and is a cornerstone in both the International Civil Aviation Organization’s and the European Aviation Safety Agency’s (EASA’s) safety management system (SMS) models. ...
    • Advancing safety in organisations: application via the Luton Safety stack 

      Smeltink, J.; Stroeve, S.; Kirwan, B. (MATEC Web of Conferences, 2019)
      Controlling and improving safety in organisations is achieved using a Safety Management System (SMS). Notwithstanding the variety of components considered in SMS standards, including human factors and safety culture, safety ...
    • Soap bubbles for large-scale PIV in industrial wind tunnels 

      Engler Faleiros, D.; Tuinstra, Marthijn; van Rooijen, Bart D.; Scarano, F.; Sciacchitano, A. (Universität der Bundeswehr München, 2019)
      This work evaluates the use of helium-filled soap bubbles (HFSB) for Particle Image Velocimetry (PIV) measurements at high Reynolds numbers (up to 3.2 million) in aeronautics. The measurements are performed in the Low Speed ...
    • Wind tunnel flutter testing on a highly flexible wing for aeroelastic validation in the transonic regime within the HMAE1 project 

      Govers, Yves; Mai, Holger; Arnold, Juergen; Dillinger, Johannes K.S.; Pereira, Allan K.A.; Breviglieri Jr., Carlos; Takara, Edgard K.; Correa, Manoela S.; Mello, Olympio A.F.; Marques, Rodrigo F.A.; Geurts, E.G.M.; Creemers, R.J.C.; Timmermans, H.S.; Habing, R.; Kapteijn, K. (2019-06)
      The aircraft manufacturer Embraer, the German Aerospace Center (DLR), the Netherlands Aerospace Centre (NLR) and German–Dutch Wind Tunnels (DNW) have tested an innovative highly flexible wing within an aeroelastic wind ...
    • Design and validation of a numerical high aspect ratio aeroelastic wind tunnel model (HMAE1) 

      Timmermans, H.S.; Tongeren, J.H. van; Geurts, E.G.M.; Marques, R.F.A.; Correa, M.S.; Waitz, S. (2019-06)
      The aircraft manufacturer Embraer, the German Aerospace Center (DLR), the Netherlands Aerospace Centre (NLR) and German–Dutch Wind Tunnels (DNW) have tested an innovative highly flexible wing within an aeroelastic wind ...
    • A Large-Scale European Union Study of Aircrew Fatigue During Long Night and Disruptive Duties 

      Dijk, H. van; Maij, A.; Sallinen, M.; Aeschbach, D.; Akerstedt, T. (Aerospace Medical Association, 2020)
      We examined aircrew fatigue during the following flight duty periods (FDPs) mentioned in the European Union (EU) Flight Time Limitations (FTLs): night FDPs longer than 10 h and FDPs typical of disruptive schedules (early ...
