Willemen, Ruben (author)
The absolute and relative stability are critical aspects of designing Controlled Motion Systems (CMS). The maximum attainable CMS performance depends highly on the design of the structural part and the actuator and sensor configuration, as mechanical vibrations can endanger stability. This thesis presents a method for designing CMS's using...

Flying wings are known for their limited lateral-directional stability and handling qualities. This study aims at assessing the lateral-directional handling qualities of a conceptual flying wing aircraft currently in development at TU Delft, the Flying-V. It focuses on two aspects: First assess the lateral-directional handling qualities of the...

This thesis is performed with the aim to investigate whether split flaps can be a feasible solution for increasing the Flying V directional control power. In order to do so, a set of wind tunnel experiments have been concluded with a 4.6% half wing model in the Open-Jet-Facility at the Delft University of Technology. Here, several split flap...

It is envisioned that the future generations of regional and short to medium-range aircraft employ a high level of propeller integration to achieve low-emission flight. The objectives of unconventional propeller installations include the enhancement of the airframe aerodynamic efficiency, increasing the propeller efficiency, improving cabin...

Kuijpers, Jan-Willem (author)
With standard aircraft configurations reaching their limits in efficiency, new aircraft configurations are being theorized and analyzed. One type of analysis is remotely piloted scaled flight tests. One of the aspects that can be analyzed through remotely piloted scaled flight tests is the dynamic behavior of the aircraft. This thesis shows a...

A new aircraft configuration, the Delft University Unconventional Configuration (DUUC), was recently invented by the Flight Performance and Propulsion group at TU Delft. As a solution to the concerns regarding the environmental and health impact due to increasing demand of air travel. The DUUC has a characteristic feature which consist of two...

Propellers were the first means of powered propulsion for aircraft. However the development of propellers stalled due to the growing interest in jet propulsion. Due to the growing interest in more fuel efficient and environmentally responsible aviation, propeller research is currently seeing a resurgence. <br/><br/>Wingtip-mounted propellers are...

Replacing conventional generation by power electronics based generation changes the dynamic characteristics of the power system. This results among others in the increased susceptibility to sub synchronous oscillations (SSO). This paper proposes a systematic procedure for mitigating the interactions between a DFIG and a series compensated...

Differential thrust can be used for directional control on distributed electric propulsion aircraft. This thesis presents an assessment of flight dynamics and control of differential thrust aircraft under engine inoperative conditions with minimum control speed. A methodology consisting of an aerodynamic data acquisition module and a non-linear...

van der Meer, Sylvain (author)
A propeller has a high propulsive efficiency, yet inherently leaves the air it propels swirling. The efficiency of a propeller can be enhanced by placing it in the tip vortex of a wing. Such a tip-mounted propeller configuration lets the vortex created by the wing and the vortex created by the propeller counteract each other, enhancing the...

The replacement of conventional generation by power electronics-based generation changes the dynamic characteristics of the power system. This results in, among other things, the increased susceptibility to subsynchronous oscillations (SSO). First, this paper discusses three recently emerging SSO phenomena, which arise due to the interactions...

The phase imbalance compensation concept is proposed in literature as an alternative way to mitigate classical subsynchronous resonance (SSR) problems in series-compensated transmission lines. However, a fundamental analysis to determine this concept's ability to mitigate resonances between a doubly-fed induction generator (DFIG) and a series...

In early design stages of aircraft, component sizing is to a large extent based on semi empirical methods, which are generally lacking for unconventional aircraft configurations. This increases the uncertainty of the performances of the generated design, such as its stability and controllability. This work aims at using a more physics-based...

Timmerman, L.B. (author)
The vertical tail size of a multi-engine aircraft is typically driven by the directional control requirement during one-engine-inoperative flight. This results in the vertical tail being over-sized for most regularly occurring flight conditions. By adding thrust vectoring technology to an aircraft, the vertical tail can be designed to cope with...

This thesis is part of a project that focuses on developing an optimisation framework for dynamically scaled flight testing. The optimisation framework must design the scale model and the flight test such that the performance of the scale model is representative to the full-scale aircraft. The similarity in the performances between the scale...

As the aviation industry continues to strive for improvements in fuel efficiency throughout the entire aircraft design, interest has been renewed in propeller engines. New research into advanced turboprop engines, so-called open rotor engines, seems promising as they combine the inherent high propulsive efficiency of ordinary turboprop engines,...
