de Jonge, H.W.G. (author)One of the most urgent problems of ATM is to reduce delays and to improve the punctuality of air traffic arriving at congested hub-airports. Layered planning with refinement and convergence in time and space, as proposed by EATMP [European ATM Programme], could give the required support for better use of these scarce resources. Refined Flow...report 2002

Vink, W.J. (author), de Jonge, J.B. (author)The present report is part of a "Manual" on aircraft loads, that is being prepared by NLR. It contains a computer program, to be used in combination with "MATLAB4 for Windows" (Student Edition) software, to study aircraft loading due to turbulence. It includes a simple aircraft response model with two rigid and three flexible symmetric degrees...report 1997

de Jonge, J.B. (author), Hol, P.A. (author)Fatigue meter data obtained during operational flights of Fokker F27 and Fokker F28 aircraft were re-processed and analyzed to study the variation in load experience between different aircraft of the same type. The Data covered about 470000 flights, made by 101 aircraft of 51 different operators. A simple algorithm was developed to quantify the...report 1996

de Jonge, J.B. (author)The present review gives a brief summary of the work performed in the Netherlands in the field of aeronautical fatigue, during the period from March 1993 until March 1995. The contributions come from three different sources, namely: The National Aerospace Laboratory (NLR) • The Department of Aerospace Engineering, Delft University of Technology ...report 1995

de Jonge, J.B. (author), Vink, W.J. (author)Standard methods for the calculation of Design Continuous Gust Loads cannot be applied in the case of aircraft with nonlinear response characteristics. In such cases, Design Loads can be calculated using stochastic simulation techniques. These techniques, however, require a very large computational effort. Hence, alternative methods, indicated...report 1994

de Jonge, J.B. (author)Modern aircraft structures are designed to be damage tolerant and to have an adequate durability. The Damage Tolerance provides structural safety in case of inadvertent cracking, the Durability determines the time that the structure can be kept in service in an economically acceptable way. Many aircraft are planned today to be kept in service...report 1994

Ottens, H.H. (author), de Jonge, J.B. (author)The present paper gives a brief review of current and planned research at NLR related to the problems associated with Ageing Aircraft. This research is primarily directed towards the prevention of Ageing Aircraft problems in future aircraft and is concentrated on two areas: - prevention of MSD in lap joints; - improved knowledge on operational...report 1992

de Jonge, J.B. (author)Many military aircraft are used more severely and over a longer periodthan originally intended. Consequently, a careful life management, including service load monitoring has become indispensable. This paper describes the development of a simple method to quantify the severity in terms of "potential crack growth" of recorded load spectra. This...report 1992

de Jonge, J.B. (author)Using a relatively simple model, calculations are made of the effect of various load spectrum variations on fatigue damage accumulation for fighter aircraft, with specific reference to RNLAF F-16 A/B aircraft. As the larger part of the total damage is due to manoeuvres with peak value between An = 3.5 and An = 6, reduction of manoeuvring in this...report 1989
