This thesis investigates the aerodynamics of a propeller-wing-flap system, spurred by the growing interest in propeller-driven aircraft and the potential introduction of distributed electric propulsion. The research focuses on the complex flowfield involving the interaction of the propeller slipstream with the main wing and flap at high-lift...

The advent of distributed electric propulsion aircraft concepts requires novel physics-based analysis methods for the modeling of the complex aerodynamic interactions between the closely coupled rotor, wing, and flap. For this purpose, the analysis tool Open Rotor-Wing-Flap Interaction Solver (ORWFIS) is developed with existing and novel low...

Aviation is responsible for a large part of the emissions due to transportation, which is why, in recent years, a trend towards implementing sustainability in aviation has emerged. In small aircraft, the concept of Leading-Edge Distributed Propulsion (LEDP) can provide aerodynamic advantages to reduce fuel consumption thanks to the ability to...

A new field of study has arisen within Wind Energy known as ‘Airborne Wind Energy’ (AWE). Although the concept of AWE has been around for a long time, there has been little development in this field until recently. This thesis adds to this development.<br/><br/>The focus lies on airfoil design in order to improve existing AWE systems and...

As an alternative to conventional wind turbines, this study considered kites with onboard wind turbines driven by a high airspeed due to crosswind flight (“drag power”). The hypothesis of this study was, that if the kite's lift coefficient is maximized, then the power, energy yield, allowed costs and profit margin are also maximized. This...

A method is presented for concurrent aerostructural optimization of wing planform, airfoil and high lift devices. The optimization is defined to minimize the aircraft fuel consumption for cruise, while satisfying the field performance requirements. A coupled adjoint aerostructural tool, that couples a quasi-three-dimensional aerodynamic...

As the complexity of high-tech systems continuously increases, engineers look for possibilities to reduce time and cost of the development of these systems. Architecture-based design enables a front-loaded design process with knowledge reuse. By enabling the automatic synthesis of simulation models, different configurations of an architecture...

Current wing design processes are strongly governed by cruise design requirements. This approach to wing design leaves little room for high-lift device design optimization where trade-offs may be required between cruise wing and high-lift wing design. Moreover, the optimization of high-lift devices typically focuses on optimizing flap/slat...

A new methodology has been developed that integrates the preliminary wing design with trailing edge high-lift systems and accounts for three-dimensional flap kinematics. The high-lift system in the developed application includes the kinematic synthesis of four common mechanisms (dropped-hinge, four-bar, link-track and hooked-track) and a...

Optimization of a single slotted flap with dropped hinge is performed with the objective of increasing the payload of a propeller driven 4-seater general aviation aircraft. Within the optimization loop, two-dimensional aerodynamic characteristics are evaluated using the MSES code, while three-dimensional aerodynamic characteristics and weight...

A current focus in the quest for improvement in fuel efficiency in aircraft design is the simplification of complex high lift systems. A simpler high lift system in combination with flow separation control is potentially able to meet the current high lift performance requirements, while still reducing overall complexity. Passive flow separation...

Relatively high wing loading leads to increase in fuel efficiency in commercial as well as in small general aviation aircraft, but requires sophisticated high lift devices to keep the take-off and landing distances within acceptable limits. High lift devices can in turn have a detrimental effect on cruise performance, and thus fuel efficiency,...

The application of morphing structures in conventional aircraft is a method to improve aircraft performance by both reducing the total fuel consumption for a given mission profile, or by allowing one type of aircraft to perform a wider range of missions. The current generation of aircraft does not widely use morphing technology to optimize...

In today’s highly competitive aviation industry, continuous efforts are being directed towards reducing design time and simplifying systems. One of the prime aspects of aircraft design is the development of high-lift systems, which are used to obtain satisfactory performance in low-speed flight. The associated design and integration of high-lift...

Within the next few years, numerical shape optimisation based on high-fidelity methods is likely to play a strategic role in future aircraft design. In this context, suitable tools have to be developed for solving aerodynamic shape optimisation problems, and the adjoint approach—which allows fast and accurate evaluations of the gradients with...

The design of complex aircraft elements such as high-lift devices has large influence on the performance of modern transport airplanes. At the cost of increased wing weight, these devices are included in the wing to ensure safe takeoff and landing. In order to meet sustainability challenges on future air transportation systems, high-lift devices...

A multi-objective design exploration for a three-element airfoil consisted of a slat, a main wing, and a flap was carried out. The lift curve improvement is important to design high-lift system, thus design has to be performed with considered multi-angle. The objective functions considered here are to maximize the lift coefficient at landing and...
