Gaukroger, D.R. (author), Curran, J.K. (author)Control surface flutter of the wing torsion-control rotation type has been investigated for an unswept wing with an under-massbalanced, half span, outboard aileron. Thirteen pairs of wings were tested, using ground launched rocket driven vehicles, and a range of values of aileron natural frequency was covered. The test results snowed...report 1962

Gaukroger, D.R. (author), Curran, J.K. (author), Marriot, A.T. (author)Measurements and calculations of aileron effectiveness for an elastic model wing in low speed flow are described. The experimental technique enabled rolling moments due to applied aileron and to rate of roll to be measured separately. Rolling moments were also calculated using measured flexibility coefficients and factored two-dimensional steady...report 1962

Curran, J.K. (author)Low speed flutter tests have been made on an all-moving model fin to ascertain the effect of mass balance at a position on the leading edge near the root. The stiffness of the joint forming the roll axis for the model was also varied. Good agreement is obtained be tween the experimental results and analytical predictions. As the stiffness at the...report 1963

Castagne, S. (author), Curran, R. (author), Rothwell, A. (author), Price, M. (author), Benard, E. (author), Raghunathan, S. (author)A methodology to estimate the cost implications of design decisions by integrating cost as a design parameter at an early design stage is presented. The model is developed on a hierarchical basis, the manufacturing cost of aircraft fuselage panels being analysed in this paper. The manufacturing cost modelling is original and relies on a genetic...journal article 2008

Bouarfa, S. (author), Blom, H.A.P. (author), Curran, R. (author), Everdij, M.H.C. (author)Purpose Commercial aviation is feasible thanks to the complex socio-technical air transportation system, which involves interactions between human operators, technical systems, and procedures. In view of the expected growth in commercial aviation, significant changes in this socio-technical system are in development both in the USA and Europe....journal article 2013

Vert, M.P.J. (author), Sharpanskykh, Alexei (author), Curran, R. (author)Resilience is commonly understood as the capacity for a system to maintain a desirable state while undergoing adversity or to return to a desirable state as quickly as possible after being impacted. In this paper, we focus on resilience for complex sociotechnical systems (STS), specifically those where safety is an important aspect. Two main...journal article 2021

Newcamp, Jeffrey (author), Verhagen, W.J.C. (author), Curran, R. (author)It is well known that aircraft fleets are aging alongside rising operations and support costs. Logisticians and fleet managers who better understand the milestones and timeline of an aging fleet can recognise potential savings. This paper outlines generalised milestones germane to military aircraft fleets and then discusses the causes that lead...journal article 2017

Koornneef, H. (author), Verhagen, W.J.C. (author), Curran, R. (author)Aircraft dispatch involves determining the optimal dispatch option when an aircraft experiences an unexpected failure. Currently, maintenance technicians at the apron have limited access to support information and finding the right information in extensive maintenance manuals is a time-consuming task, often leading to technically induced...journal article 2021

Ho-Huu, V. (author), Hartjes, S. (author), Visser, H.G. (author), Curran, R. (author)The multi-objective evolutionary algorithm based on decomposition (MOEA/D) has been recognized as a promising method for solving multi-objective optimization problems (MOPs), receiving a lot of attention from researchers in recent years. However, its performance in handling MOPs with complicated Pareto fronts (PFs) is still limited,...journal article 2018

Deng, Q. (author), Santos, Bruno F. (author), Curran, R. (author)This paper presents a practical dynamic programming based methodology to optimize the long-term maintenance check schedule for a fleet of heterogeneous aircraft. It is the first time that the long-term aircraft maintenance check schedule is optimized, integrating different check types in a single schedule solution. The proposed methodology...journal article 2020

To address this issue, Nature-Based Solutions (NBSs) are often adopted as innovative and sustainable flood risk management methods. Besides the flood risk reduction benefits, NBSs offer co-benefits for the environment and society. However, these co...journal article 2024

Newcamp, Jeffrey (author), Verhagen, W.J.C. (author), Curran, R. (author)Military attack aircraft are susceptible to the harmful effects of widespread fatigue damage caused by cyclic loading of structural components, which leads to airframe retirement. Modern structural health monitoring techniques use a multitude of sensors and high data collection rates. Some legacy airframes, which are most susceptible to fatigue...journal article 2016
