From the Wright Flyer to fly-by-wire, the phenomenon of pilot-induced oscillations (PIO) has persisted, evolving with the complexity of the airframes and their associated flight control systems. Though airframe designers have long recognized the threat posed by PIO, each generation has been forced to address the issue whether identified in...

Torelli, Riccardo (author)
The Flying-V novel aircraft design aims at reducing fuel consumption by an innovative low-drag, fuselage-free geometry. However, possible issues related to certification requirements have been noted regarding longitudinal handling qualities at low speed, the pull-up manoeuver, and the flight path angle response. This study aims at investigating...

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...

The handling qualities of an aircraft are an important aspect in aircraft design, especially for novel configurations. The Flying V is a flying wing passenger aircraft designed to transport about 300 passengers. The handling qualities of such a new configuration aircraft are to be investigated before the aircraft can continue in its design...

Over the last five decades, the majority of commercial aircraft consisted of the traditional tube-and-wing configuration. This traditional configuration is approaching a fuel efficiency asymptote. Besides that, with the increasing number of passengers and cargo transported by air every year, and environmental impact as an important factor in...

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...

Model predictive control is an optimal, model-based control method that has the powerful capability of directly including input and output constraints. Next to this, it is known that helicopters are hard to fly with its complex, unstable and highly coupled dynamics. With the introduction of the concept of handling qualities, guidelines for...

Juffermans, Stefan (author)
For decades the physical appearance of aircraft remained more or less unchanged. The increase in efficiency which still can be made by improving this design, is limited. More researchers have started to investigate new design options that represent a departure from established concepts. The main drivers behind these endeavors are the tightening...

Control augmentation systems based on Incremental Nonlinear Dynamic Inversion (INDI) are able to provide high-performance nonlinear control without the need for a model of the complete system. Considering a pitch rate control law for a fixed-wing aircraft, only a model for the elevator control effectiveness (CE) and sensor feedback of the pitch...

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...

Yilmaz, D. (author)
Flight safety has been a fundamental aspect of aircraft, and the future demand for wider usage of aerial operations leads to more focus on the flight safety. Particularly rotorcraft require high standards of flight safety due to their inherent features, such as complicated rotary mechanisms, close-to-ground operations, and complex aerodynamic...

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...

With the introduction of the BS115, an ultra-light two-seater general aviation aircraft, a new opportunity for military pilot training is presented. To increase the training potential of this aircraft, the training effectiveness has been investigated. Previous research on training effectiveness assessment has failed to address the influence of...

Maximum unnoticeable added dynamics (MUAD) envelopes have been largely used to assess the adequacy of low-order equivalent systems (LOES) in handling qualities assessment and simulator validation. However, research has shown that more thorough verification of the adequacy of this method is required. This paper studies the influence of the...

Mutluay, T. (author)
Mass of an aircraft as well as distribution of it along the body are important concerns during the design process due to their significant influence on performance and inertia. Inertia of an aircraft has to be known in order to examine the handling qualities, which have a large effect on aircraft’s design. However, due to the smeared properties...

Damveld, H.J. (author)
The future demand for larger and lighter civil transport aircraft leads to more flexible aircraft, which bring their own controlling and handling problems. A review of established handling qualities methods showed that they were either unsuitable for aeroelastic aircraft, or had significant disadvantages. After consideration of the basic...
