Book Description :

The development of lightweight, flexible wings to improve the performance of an aircraft has been a desire of aircraft engineers since the dawn of the aerospace industry. For many years, wings have been designed stiff to counteract flutter and to meet the need for high speeds. Ailerons and flaps are primarily used for controlling the maneuverability of an aircraft. However, the mechanical actuation systems for these devices contribute significant weight to the wings and thus limit the performance of an aircraft. To reduce weight and increase the maneuverability of an aircraft, a wing morphing technique is proposed in this paper. This technique assumes that the wing structure is flexible enough to allow the wing to twist or bend to control the maneuverability of an aircraft without using ailerons or flaps. However, flexible wings require energy to deform and flutter is still a very important issue that needs to be addressed for flexible wings. Hence, the relationship between the degree of flexibility to meet stated performance requirements and both the desire for minimum control energy and the requirement for flutter avoidance is explored in this research. The research was conducted to determine how wing structural stiffness affects the energy required to deform the wing and to give insight into its performance range for which flutter is to be avoided. The study incorporates structural and aerodynamic modeling, control-design optimization, and a candidate wing morphing technology. The results provide important information that designers of morphing wings can consult to explore the potential benefits of morphing wing technology.

Book Description :

Over the next few years the aviation industry will face the challenge to develop a new generation of air vehicles characterised by high aerodynamic efficiency and low environmental impact. The technologies currently available, however, are inadequate to meet the demanding performance requirements and to comply with the stringent regulations in terms of polluting emissions. An innovative and very promising solution is offered by airframe morphing technologies. Morphing wing structures, internally actuated and able to change their shape smoothly to adapt to different loading conditions, would be able to achieve near-optimal lift and drag profiles throughout all the different phases of the flight. This would enhance the aircraft aerodynamic performance and contribute to a significant reduction of the fuel consumption, polluting emissions and noise. The present study has been conducted as part of the European Commission founded Seventh Framework Program called \Smart High Lift Device for the Next Generation Wing" (SADE). The aim of this research is the development of an effective design of a morphing ap with flexible trailing edge for a commercial aircraft wing. The investigation focused on morphing concepts which are suitable for large transport aircraft and which can be effectively developed and become operational within the next 20 years. For these reasons, the morphing was limited to the high lift devices of the wing, while the conventional wing box structure was retained. Cont/d.

Book Description :

This thesis presents results of the application of energy-based large-scale optimization of a two-subsystem (propulsion subsystem (PS) and airframe subsystem-aerodynamics (AFS-A)) air-to-air fighter (AAF) with two types of AFS-A models: a fixed-wing AFS-A and a morphing-wing AFS-A. The AAF flies 19 mission segments of a supersonic fighter aircraft mission and the results of the study show that for very large structural weight penalties and fuel penalties applied to account for the morphing technology, the morphing-wing aircraft can significantly outperform a fixed-wing AAF counterpart in terms of fuel burned over the mission. The optimization drives the fixed-wing AAF wing-geometry design to be at its best flying the supersonic mission segment, while the morphing-wing AFS-A wing design is able to effectively adapt to different flight conditions, cruising at subsonic speeds much more efficiently than the fixed-wing AAF and, thus yielding significant fuel savings. Also presented in this thesis are partially optimized results of the application of a decomposition strategy for large-scale optimization applied to a nine-subsystem AAF consisting of a morphing-wing AFS-A, turbofan propulsion subsystem (PS), environmental controls subsystem (ECS), fuel loop subsystem (FLS), vapor compression/polyalphaolefin loop subsystem (VC/PAOS), electrical subsystem (ES), central hydraulics subsystem (CHS), oil loop subsystem (OLS), and flight controls subsystem (FCS). The decomposition strategy called Iterative Local-Global Optimization (ILGO) is incorporated into a new engineering aircraft simulation and optimization software called iSCRIPT(TM) which also incorporates the models developed as part of this thesis work for the nine-subsystem AAF. The AAF flies 21 mission segments of a supersonic fighter aircraft mission with a payload drop simulating a combat situation. The partially optimized results are extrapolated to a synthesis/design which is believed to be close to the system-level optimum using previously published results of the application of ILGO to a five-subsystem AAF to which the partially optimized results of the nine-subsystem AAF compare relatively well. In addition to the optimization results, a parametric study of the morphing AFS-A geometry is conducted. Three mission segments are studied: subsonic climb, subsonic cruise, and supersonic cruise. Four wing geometry parameters are studied: leading-edge wing sweep angle, wing aspect ratio, wing thickness-to-chord ratio, and wing taper ratio. The partially optimized AAF is used as the baseline, and the values for these geometric parameters are increased or decreased up to 20% relative to an established baseline to see the effect, if any, on AAF fuel consumption for these mission segments. The only significant effects seen in any of the mission segments arise from changes in the leading-edge sweep angle and wing aspect ratio. The wing thickness-to-chord ratio shows some effect during the subsonic climb segment, but otherwise shows no effect along with the taper ratio in any of the three mission segments studied. It should be emphasized, however, that these changes are made about a point (i.e. synthesis/design), which is already optimal or nearly so. Thus, the conclusions drawn cannot be generalized to syntheses/designs, which may be far from optimal. Also note that the results upon which these conclusions are based may very likely highlight a weakness in the conceptual-level drag-buildup method used in this thesis work. Further optimization studies using this drag-buildup method may warrant setting the thickness-to-chord ratios and taper ratios rather than having them participate in the optimization as degrees of freedom (DOF). The final set of results is a parametric study conducted to highlight the correlation between the fuel consumption and the total exergy destruction in the AFS-A. The results for the subsonic cruise and supersonic cruise mission segments show that at least for the case when the AFS-A is optimized by itself for a fixed specific fuel consumption that there is a direct correlation between the fuel burned and total exergy destruction. However, as shown in earlier work where a three-subsystem AAF with AFS-A, PS, and ECS is optimized, this may not always be the case. Furthermore, based on the results presented in this thesis, there is a smoothing effect observed in the exergy response curves compared to the fuel-burned response curves to changes in AFS-A geometry. This indicates that the exergy destruction is slightly less sensitive to such changes.

Book Description :

Advances in materials, actuators, and control architectures have enabled new design paradigms for unmanned aerial vehicles based on biological inspiration. Indeed, there has been a recent drive to design aircraft features and behaviors based on those of birds, insects, and flying mammals. This dissertation focuses on one such bio-inspired maneuver, perching, which can be described as a low-thrust, aerodynamically controlled, planted landing. While planted landings are possible in helicopters and jump jets, it has yet to be achieved on a low-thrust, high-efficiency platform such as a long loiter reconnaissance aircraft. It is proposed that in-flight shape reconfiguration can enable this class of aircraft to execute this maneuver without sacrificing its cruise performance. This dissertation discusses the perching problem at various levels, from the aerodynamics of the wing to the complete trajectory of the maneuver. A lifting-line technique, a variant of Weissinger's classical method, is developed to analyze the aerodynamics of morphing wings in the attached flow regime. This tool is used both to study the effects of morphing on a wing's loading and to populate a database of aerodynamic coefficients for simulating the perching aircraft. Thusly, the aircraft is simulated in the longitudinal plane and compared to a similar fixed-configuration aircraft. Trim and stability analyses are performed on each aircraft in order to clarify the effects of morphing on the aircraft's longitudinal dynamics. Finally, viable perching trajectories, which bring the aircraft from a cruise configuration to a planted landing, are developed and optimized in terms of their spatial requirements. Three classes of aircraft are simulated in this optimization study: point-mass, fixedconfiguration (i.e. conventional), and morphing aircraft. Comparisons of these classes show that fixed-configuration aircraft are limited by their pitch maneuverability, whereas morphing can alleviate these limitations by increasing the available pitch authority. It is concluded that morphing increases pitch controllability during the maneuver while simultaneously decreasing the spatial requirements of the perching maneuver. (Abstract).
