The developments in the field of aerospace materials and structures allow the more light weight air vehicles. However, the aircraft body, particularly wing, can deform more appreciably due to the occurrence of flow separation and flutter. Therefore, active control is necessary in order to maintain structural integrity. One of the proposed...

This paper presents a method to assess the key performance indicators of aircraft designed for minimum direct operating cost and aircraft designed for minimum global-warming impact. The method comprises a multidisciplinary aircraft optimization algorithm capable of changing wing, engine and mission design variables while including constraints on...

In this study, unsteady RANS simulations are performed to investigate the effect of over-the-wing (OTW) propeller inclination on the aerodynamic interaction with a wing featuring a plain flap. A comparison to experimental data shows that the numerical approach is capable of modeling the wing and propeller separately and can capture the effect of...

In-flight non-normal events can be rather taxing for a flight crew. Numerous tasks, often competing for attention, need to be handled adequately after which, the best plan of action for the remainder of the flight needs to be determined. In the light of recent developments towards reduced crew operations, the demand for reducing workload has...

Non-normal event resolution in-flight can be challenging on the flight crew with increased time pressure, workload, stress. Other competing tasks impose a risk on flight safety and burdens the decision-making process. Pilots rely on checklists to aid in their effort, which in its state-of-the-art form are presented on the dedicated Electronic...

An experimental parametric study of the effect of discrete roughness elements (DRE) on the development and breakdown of stationary crossflow instability on a swept wing is presented. A systematic investigation of the receptivity to various elements height and chord locations is carried out in a crossflow dominated flow. The flow is globally and...

We study the interaction between a stationary crossflow instability and forward-facing steps in a swept-wing boundary layer using Direct Numerical Simulations (DNS). The station- ary primary crossflow mode is imposed at the inflow. Steps of several heights are modeled. Particular emphasis is placed on ensuring a fully stationary solution, in...

Advancements in aircraft controllers and the tendency towards increasingly lighter and more flexible aircraft designs create the need for adaptive and intelligent control systems. While lighter aircraft structures have the potential to show better structural and aerodynamic efficiency, they are also more susceptible to dynamic loads. A key...

This paper presents a novel methodology for measuring the drag latency of touchscreens. Drag latency is a characteristic of touch hardware that can affect key metrics of human performance as typically collected in human-in-the-loop (simulator) experiments. The proposed methodology uses a laser and laser sensor to obtain an external measurement...

Modern aircraft use a variety of fly-by-wire control devices and combine these with a flight envelope protection system to limit pilot control inputs when approaching the aircraft limits. The current research project aims to increase pilot awareness of such a protection system through the use of force feedback on the control device, i.e.,...

Securing fresh water supply on the Dutch Caribbean islands, former colonial overseas territories of The Netherlands from the 17th century, always has been, and still is, a challenge. Between 1904 and 1915 the cartographers Werbata and Jonckheer drew the first topographical maps of the islands. Detailed data was needed for the (re-)development of...

World Heritage cities (WHC), meaning urban areas, often in part, inscribed at the UNESCO World Heritage list are valuable heritages to many local and global communities and, therefore, attract efforts to conserve them. Nonetheless, these cities are increasingly under pressure, by globalization, climate change, and tourism. An integral approach,...

The Government of Dubai implemented Green Building Regulations & Specifications & Specifications (GBRS). In March 2014. Dubai has more than 1000 high-rise buildings in which more than 2 million residents are accommodated. However, 62% of the existing residential high-rise buildings dating from 1970-2014 do not meet the requirements of...

The Old City of Aleppo, one of the oldest continuously inhabited cities in the world, has been inscribed on UNESCO’s World Heritage List in 1986. In the early 1990s the Aleppo municipality initiated the project for the Rehabilitation of the Old City with the German Technical Cooperation Agency (GTZ) as a partner. As part of the process, a...

Since 2019, a key element of simulator-based training of airline pilots is stall training. A major and still largely open research question is which level of model fidelity is required for effective training. As part of an effort to answer this question, a model of the quasi-steady stall dynamics of a Cessna Citation II aircraft is identified...

The Hyperloop is a concept of a ground transportation system consisting of capsules (called pods) traveling at very high-speeds in near-vacuum tubes. The hyperloop aims to be a fast, cheap, and sustainable alternative to short-haul flights and high-speed rail. The small pod size requires very high frequencies to respond to future high levels of...

Cities are the main drivers in the race to sustainable development, and the needed transformations would affect their built environment. Transformations through development plans or projects are often regulated by local planning policies, which are assumed to simultaneously enable transformation and the conservation of irreplaceable resources...

In this study, the design and development of an autonomous morphing wing concept were investigated. The morphing wing was developed in the scope of the Smart-X project, aiming to demonstrate in-flight performance optimisation. This study proposed a novel distributed morphing concept, with six Translation Induced Camber (TRIC) morphing trailing...

In this paper, we aim to effectively suppress the spread of epidemic/information via blocking/removing a given fraction of the contacts in a temporal (time evolving) human contact network. We consider the SI (Susceptible- Infected) spreading process, on a temporal contact network to illustrate our methodology: an infected node infects a...
