Deployable morphing aircraft are gaining popularity in the academic and industrial world. Their deployability offer the possibility to be stored and takes less space. This is advantageous in volume limited applications like space explorations, where every cubic centimeter is important. Another field where this aircraft is increasingly used is...

Current Ballistic Missile (BM) defence systems intercept an incoming threat in its terminal phase, and to some extend during its coast phase. During the boost phase of a BM, the initial velocity of the BM is low and the hot exhaust plume is easy to spot for infrared sensors, which provides a good opportunity for interception. To do so, the...

With increasing fuel prices, airlines are searching for means to reduce fuel consumption. Due to the limited variables that operators can influence of an aircraft, they are left with only operational changes, such as center of gravity positioning. By shifting the center of gravity aft, achieved by loading heavy cargo and baggage in the rear,...

New generation combat aircraft are expected to operate over extended flight envelopes, including flight at high flow angles and rapid maneuvers. Conditions beyond traditional limits are giving rise to nonlinear phenomena, such as flow separation, large scale energetic vortices, fluctuations etc. These phenomena have significant impact on...

Preface In the wake of the economical crisis of 2008, the shipping industry changed from a very profitable industry to a struggling one, aiming to optimize vessel operations in order to survive. Theories regarding route optimization based on weather and oceanic currents exist, but only few reliable industrial applications can be found. This,...

The flow field subjected to the influence of the helicopter rotor is characterized by its three-dimensional pattern and unsteadiness. The accurate modeling of the flow around the rotor blades addressed by Computational Fluid Dynamics (CFD) simulations is associated with high computational costs. The complexity of the analysis can be reduced by...

Aircraft design methodologies have been significantly developing from the past few years with the advancements in knowledge based techniques. These methods enable the storage of design knowledge and rules, and reuse them to create different types of designs, thus preventing the designer to perform repetitive tasks. Tasks such as parametric...

The solution space for conflicts between aircraft consists of velocity, heading and altitude changes. In the current design of the air traffic controller workspace the instantaneous values for velocity, heading and altitude can all be found in the aircraft labels on the radar, however the heading and velocity can also be derived from the...

Helicopters are complex and expensive aircraft with a level of technology that is immature compared to fixed- wing counterparts. Helicopters suffer from vibratory loads stemming from the main rotor and exhibit control and stability problems in the low-speed flight regime. Operating a helicopter near the limits of its flight envelope may result...

During aircraft design,multiple tools are utilised to inspect the performance of the configuration. As the design matures, higher fidelity analyses are conducted to predict the flight dynamics of the aircraft. These analyses are conducted by using semi-empirical relations, numerically analysing flow behaviour, conducting wind-tunnel tests and...

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...

Air traffic is expected to grow over the next few decades, which will cause the global fuel consumption to increase. Reducing the drag of an aircraft will result in a reduction of the fuel consumption. Non-planar configurations may offer a solution to reduce the drag while maintaining the performance of today’s aircraft. The aim of this study is...

At present ship-helicopter qualification testing is an expensive process, both in terms of time consumed (months) and costs (> hundred-thousand euros). The Netherlands Aerospace Centre (NLR) has developed a more effective means for qualification testing - reducing the costs up to 50% and cutting the time required. The key of this process is the...

The Objective Motion Cueing Test (OMCT) refers to a way to measure motion characteristics of a simulation objectively, by constructing so-called frequency response functions of the cueing system. Research in recent years has applied the OMCT to a number of fixed-wing research simulators. However, the effect of aircraft dynamics on predicted...

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...

Aircraft wings are becoming more flexible, making it important to take this flexibility into account from the start of the design process. With flexible wings, unsteady (time-varying) aerodynamics becomes important. For this reason, an unsteady aerodynamics model was constructed and coupled to an aeroelastic flight mechanics tool. This allows...

Force feedback in helicopters can improve the performance of the pilot, decrease direct maintenance costs and increase the safety of every flight. Traditional force feedback is done with the use of a force sensor. In this thesis the use of a position based, feedforward control loop to achieve the same purpose is investigated. The limits of...

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...

Both NASA and the EU have set ambitious goals in terms of aircraft emission reduction. Previous studies have indicated that these goals can not be met with evolutionary improvements of conventional technologies. For this reason there is a need for revolutionary aircraft concept and/or radical innovative systems. One such concept is the use of a...
