Świderski, Adam (author)
As the Flying-V goes through subsequent design iterations, each new model requires dedicated handling qualities research. A part of that work, namely obtaining the handling qualities predictions, is highly repetitive and can be automated. To address that issue, a Python library for automated handling qualities prediction evaluations of the...

Advancements in aircraft performance require increasingly complex design processes and tools. Simulating the unsteady non-linear aerodynamic interaction between a maneuvering aircraft and the surrounding flowfield poses serious challenges. High-Fidelity Computational Fluid Dynamics (CFD) methods, based on the numerical solution of the Navier...

By 2050, the aviation industry is expected to grow by 250-300% of its current air traffic. If left unchecked, the corresponding increase in atmospheric and noise pollution will have a catastrophic impact on the environment. Thus, improvements in aircraft design are urgently needed for a sustainable growth of the aviation industry. The...

Growing interest in unconventional aircraft designs coupled with miniaturization of electronics and advancements in manufacturing techniques have revived the interest in the use of Sub-scale Flight Testing (SFT) to study the flight behaviour of full-scale aircraft in the early stages of design process by means of free-flying sub-scale models....

A tiltrotor has the features of both a fixed-wing aircraft and a helicopter, thereby blending the vertical flight capabilities of helicopters with the speed, altitude, and range of fixed-wing aircraft. However, as an important aspect of piloted aircraft, the handling qualities of tiltrotor aircraft have not been studied extensively. This thesis...

The research presented in this paper focuses on the development of a quasi-Linear Parameter Varying (qLPV) model for the XV-15 tiltrotor aircraft. The specific category of qLPV modeling technique, known as the model stitching technique, is employed to model the time-varying dynamics of XV-15 tiltrotor aircraft over the entire flight envelope....

The aim of the present paper is to present an understanding of the control characteristics for representative eVTOL (Electric Vertical Takeoff and Landing) quadcopters having the same properties of interest as the eVTOL configurations developed presently in Urban Air Mobility. In this context, the paper concentrates on eVTOL quadcopters with...

Soikkeli, Johannes (author)
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...

Advanced passenger vehicles are complex dynamic systems that are equipped with several actuators, possibly including differential braking, active steering, and semi-active or active suspensions. The simultaneous use of several actuators for integrated vehicle motion control has been a topic of great interest in literature. To facilitate this, a...

Generally, performance of aircraft is optimized within the limits of adequate Handling Qualities. The dominant challenges in designing flying wings exist in their paradigm relating stability margin and the effectiveness of controls. The project, undertaken at Airbus Future Projects Office, provides a qualitative assessment of the Handling...

Wu, P. (author)
The European Union and the United States are proposing to bring in more strict flight vehicle emission criteria in their reports of the high‐level groups on aviation research, i.e. EU Flightpath 2050 and US Destination 2025. More fuel‐efficient aircraft must be developed to achieve this target. Moreover, the increasingly competitive aviation...

Ketelaars, Martijn (author)
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...

Westerveld, D. (author)
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...

Van Der Wurff, S. (author)
This work focuses on a multidisciplinary design optimization of an aircraft wing. Among others, a structural optimization of the wing stiffness is performed. For a certain stiffness model, a set of relevant load cases can be determined that have high chance to cause active constraints. The purpose of this research is to investigate if the set of...

Natella, M. (author)
The present work thus develops a low-fidelity formulation to investigate the flight dynamic stability of a flexible wing structure. The model is verified against other studies found in the relevant literature, which show interesting trends in terms of how some of the design variables or flight conditions influence the stability of the structure.

Tal, E.A. (author)
Recent developments in airframe design include the increasing application of modern lightweight materials. Airframe designs based on composite materials are able to provide sufficient structural strength at lower mass, but often have decreased structural rigidity. Flight vehicles with relatively flexible structures exhibit more prominent...

Kalthof, R.L.C. (author)
Because of the focus on weight minimization, aircraft are becoming more and more flexible. Therefore, the frequency separation between flight mechanics motion and structural vibration decreases. This calls for a flight mechanics model that includes aeroelasticity. The development of such a model was the subject of the current research. This...

During today’s aircraft descents, Air Traf?c Control (ATC) commands aircraft to descend to specific altitudes and directions to maintain separation and spacing from other aircraft. When the aircraft is instructed to maintain an intermediate descent altitude, it requires engine thrust to maintain speed, leading to increased fuel burn and noise...

Looye, G.H.N. (author)
The design of flight control laws (FCLs) for automatic and manual (augmented) control of aircraft is a complicated task. FCLs have to fulfil large amounts of performance criteria and must work reliably in all flight conditions, for all aircraft configurations, and in adverse weather conditions. Consequently, a large part of the FCL design...
