A minimization of disturbance caused by aircraft noise events and a reduction of fuel consumption during the initial and final phase of flight. These are the two objectives that play an important role in the Flexible Runway Allocation Model. By taking into account fuel consumption alongside noise annoyance, this model enables to analyze and...

The use of advancements in computing technology has enabled designers to perform more thorough and more detailed design studies. Multidisciplinary Design Optimization (MDO) architectures provide users with guidelines on how to structure their MDO problem, including the linking of disciplines and how to perform the optimization. However, complex...

In the era of increasing aviation traffic the conditions are right to promote design of ambitious concepts. At Fokker Aerostructures attention is drawn to smooth in-flight shape morphing to produce a structurally functional Variable Camber Trailing Edge Flap (VCTEF). The deployment mechanism would fit into the flap, not limiting other...

A tool is developed that is able to optimize the trajectories of multiple aircraft that fly in formation in order to obtain the minimum total fuel consumption. Several experiments are conducted to investigate the benefits of formation flight for commercial aircraft. Finally, also the influences of wind and delay on the trajectories of the...

Currently, only one Standard Instrument Departure (SID) track and one flight procedure is used per runway departure fix combination. In contrast to tailored arrivals, the potential benefit of tailored departures has been left relatively undiscovered. The research objective is to quantify the potential benefit of tailored SID-s and profile...

For the past 20 years, the small bodies of the solar system, such as asteroids and comets, have been increasingly gathering the interest of scientists and space agencies. The latter have been multiplying the number of space missions to study them. Brazil does not want to be left out and has been working on its own mission, ASTER, which has the...

The research objective of this thesis is to develop an innovative airline fleet planning concept that is capable to consider the long-term stochastic nature of air travel demand while generating meaningful results in reasonable computation times. The proposed methodology aims to identify robust fleets, in terms of profit generating capability...

Runway capacity of a complex runways system can be limited by several factors. Currently, the runway usage at Amsterdam Airport Schiphol (AAS) is described by a preference list established by multiple stakeholders. It makes an important trade-off between minimizing noise exposure to the environment and maximizing capacity. The existing model...

Topology optimization is the process of optimizing both the material layout and the connectivity inside a design domain. The first paper on topology optimization dates back to 1904, when the Australian inventor Michell derived optimality criteria for minimum weight truss structures. In 1988 Bends√łe and Kikuchi published the pioneering paper ...

At present, on the aviation market a need exists for lighter and more efficient aircraft than the ones dominating the airspace today. Beside the reduction in operating costs and air pollutants of these new generation aircraft, this reduction in fuel use can result in several advantages with respect to the performance of the aircraft like...

Interplanetary missions use gravitational slingshots around planetary bodies to adjust their heliocentric velocity or inclination for quite some time. The momentum exchange that can be achieved during a so-called gravity assist is limited by the mass of the planetary body. To overcome this limitation, an aerogravity assist was proposed, a...

An opportunity was identified to improve the traditional landing gear design process. Especially in the conceptual design phase, lots of man-hours are consumed by making the same calculations over and over again, for different concepts. Often, an existing gear is therefore used as initial starting point, to simplify the design process. This...

In order to extract the body force field that is generated by a plasma actuator from velocity data, most researchers disregard the influence of the pressure gradient to obtain a spatial and temporal description of the body force field. There is however some discussion whether this assumption is valid or not. The current research tries to compute...

A frozen orbit is an orbit chosen such that the effect of perturbations on (a combination of) the mean orbital elements is minimized. The concept first appeared in literature in 1978, and was applied that same year to the Seasat mission. This altimetry mission featured strict requirements on the accuracy of the altitude of the satellite above...

This research aims to improve the inventory planning for a logistical provider who offers aircraft component maintenance and availability to its customer. To this purpose, a classification model is introduced which makes use of two existing classification methods i.e. Analytic Hierarchy Process (AHP) and Cost Criterion in order to produce a...

Micro turbines are touted to become the prime system for the combined heat and power(CHP) applications in light of their significant advantages in terms of performance, size, costs and reduced CO2 emissions [1]. Micro Turbine Technology B.V. (MTT) is currently developing a 3KW recuperated micro turbine for such applications. Commercially...

A computationally efficient two-level design methodology is developed for the optimization of stiffened compression loaded panels having variable stiffness panels as their skin. In the first step extensive bay panel optimization is performed using a Rayleigh-Ritz energy method coupled with a specialized Genetic Algorithm. Results in agreement...

This paper presents the design procedure of a quasi-isotropic (QI) laminate employing dispersion of ply orientations. The goal is to improve damage resistance of a laminate under low velocity impact (LVI). The LVI is treated as a quasi-static loading and instead of a plate a laminated beam is considered. Therefore, this situation simplifies the...

Grid-stiffened composite structures, where the skin is stiffened by a lattice of stiffeners, not only allow for significant reduction in structural weight but are also competitive in terms of structural stability and damage tolerance compared with sandwich composite structures. As the development of Automated Fiber Placement (AFP) technology...

The primary objective of a defense aviation operator or air force, is to maximize its continued readiness to successfully perform military flight operations, whenever and wherever the home state or international community calls for it. In order to maintain a satisfactory level of operational readiness, air forces need to ensure that sufficient...
