An important problem that arises during the design of wind turbines is estimating extreme loads with sufficient accuracy. This is especially difficult during iterative design phases when computational resources are scarce. Over the years, many methods have been proposed to extrapolate extreme load distributions from relatively short time series...

The aviation sector has suffered a big blow from the series of recent economic depressions. Airlines are struggling to stay in business and are looking for multiple ways to cut on expenses. This has led to the initiation of studies to find strategies which will reduce an airline’s overall fuel consumption. One of these methods is to initiate...

With the trend of moving towards 10-20MW turbines, rotor diameters are growing beyond the size of the largest turbulent structures in the atmospheric boundary layer. As a consequence, the fully uniform transients that are commonly used to predict extreme gust loads are losing their connection to reality and may lead to gross over dimensioning....

There is a renewed interest, expressed by ISECG, to return to the Moon and establish a longer human presence on the lunar surface. Long term missions require supplies, which can be transported to the Moon by a new promising solution: the Solar Electric Propulsion (SEP) stage. The goal of this study is to create a conceptual system design (phase...

Like many vertical-axis wind turbines (vawts) of the Darrieus type, Turby fails to achieve a fully passive start-up. Experiments indicate that there is a band of negative torque—often referred to as dead band in literature—somewhere in the tip speed range 0.5 B l B 1.6. The reason behind this is that, unfortunately, the power coefficient...

Formation flying is introduced as a new and innovative air transportation system for long-haul commercial flight. With this paper the operational feasibility of formation flying is addressed, both from a market demand and economic, as well as an air traffic control perspective. Preliminary results of a case study indicate that operating a newly...

The airline industry is under continuous pressure to reduce emissions and costs. This paper investigates the feasibility for commercial airlines to use formation flight to reduce emissions and fuel burn. To fly in formation, an aircraft needs to benefit from the wake vortices of the preceding aircraft. This requires a stable aerodynamic flow,...

A first outline for the concept of formation flying is investigated. The objective is to create a sustainable air transportation system for the next generation of aircraft from a formation flying perspective. When flying in formation over long distances the trailing aircraft can benefit from the wake vortices created by the preceding aircraft....

The provision of accurate models of Glacial Isostatic Adjustment (GIA) is presently a priority need in climate studies, largely due to the potential of the Gravity Recovery and Climate Experiment (GRACE) data to be used to determine accurate and continent-wide assessments of ice mass change and hydrology. However, modelled GIA is uncertain due...

Both biological and engineering scientist have always been intrigued by the flight of insects and birds. For a long time, the aerodynamic mechanism behind flapping insect flight was a complete mystery. Recently, several experimental and numerical flow visualisations were performed to investigate the aerodynamics around flapping wings. Flapping...

The influence of different wing kinematic models on the aerodynamic performance of a hovering insect is investigated by means of two-dimensional time-dependent Navier–Stokes simulations. For this, simplified models are compared with averaged representations of the hovering fruit fly wing kinematics. With increasing complexity, a harmonic model,...

It has been generally accepted that the noise in continuous GPS observations can be well described by a power-law plus white noise model. Using maximum likelihood estimation (MLE) the numerical values of the noise model can be estimated. Current methods require calculating the data covariance matrix and inverting it, which is a significant...
