Book excerpt: NA*****Due to a highly competitive environment, the General Aviation (GA) aircraft industry of today is often forced to design their products for various purposes and markets, to gain the largest possible market share. Niche markets, as the market for training aircraft for commercial pilot training, are often only served with products developed for other markets. The market for training aircraft for commercial pilot training is a niche, but due to the increasing demand of aircraft and pilots, it is a fast growing market. In addition, the needs for environmentally friendly and sustainable solutions, as well as the increasing complexity of the integrated systems, in todays large airlines, require new concepts for this market.The thesis is structured in a theoretical and a practical part both following a stepwise research design with the aim to answer several research questions.The theoretical part analyses the current situation of the GA multi-engine pilot training aircraft and focus on factors which have to be taken into account for the designs. Furthermore this part describes how key factors and new technology can be established and evaluated. The practical part discusses the key factors and the chosen technologies for the future GA multi-engine training aircraft. Upon selection of a technology this part explains its advantages and disadvantages for possible configuration of the training aircraft. The results of practical and theoretical part provides hybrid as the suitable technology and proposes a low wing, T-tail with aft placed ducted fan engine as a conceptual design.

This book was released on 2017-05-23 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design and development of new aircraft are becoming increasingly expensive and timeconsuming. To assist the design process in reducing the development cost, time, and late design changes, the conceptual design needs enhancement using new tools and methods. Integration of several disciplines in the conceptual design as one entity enables to keep the design process intact at every step and obtain a high understanding of the aircraft concepts at early stages. This thesis presents a Knowledge-Based Engineering (KBE) approach and integration of several disciplines in a holistic approach for use in aircraft conceptual design. KBE allows the reuse of obtained aircrafts’ data, information, and knowledge to gain more awareness and a better understanding of the concept under consideration at early stages of design. For this purpose, Knowledge-Based (KB) methodologies are investigated for enhanced geometrical representation and enable variable fidelity tools and Multidisciplinary Design Optimization (MDO). The geometry parameterization techniques are qualitative approaches that produce quantitative results in terms of both robustness and flexibility of the design parameterization. The information/parameters from all tools/disciplines and the design intent of the generated concepts are saved and shared via a central database. The integrated framework facilitates multi-fidelity analysis, combining low-fidelity models with high-fidelity models for a quick estimation, enabling a rapid analysis and enhancing the time for a MDO process. The geometry is further propagated to other disciplines [Computational Fluid Dynamics (CFD), Finite Element Analysis (FEA)] for analysis. This is possible with an automated streamlined process (for CFD, FEM, system simulation) to analyze and increase knowledge early in the design process. Several processes were studied to streamline the geometry for CFD. Two working practices, one for parametric geometry and another for KB geometry are presented for automatic mesh generation. It is observed that analytical methods provide quicker weight estimation of the design and when coupled with KBE provide a better understanding. Integration of 1-D and 3-D models offers the best of both models: faster simulation, and superior geometrical representation. To validate both the framework and concepts generated from the tools, they are implemented in academia in several courses at Linköping University and in industry

Download or read book Advanced Aircraft Design written by Egbert Torenbeek and published by John Wiley & Sons. This book was released on 2013-05-28 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the overall appearance of modern airliners has not changed a lot since the introduction of jetliners in the 1950s, their safety, efficiency and environmental friendliness have improved considerably. Main contributors to this have been gas turbine engine technology, advanced materials, computational aerodynamics, advanced structural analysis and on-board systems. Since aircraft design became a highly multidisciplinary activity, the development of multidisciplinary optimization (MDO) has become a popular new discipline. Despite this, the application of MDO during the conceptual design phase is not yet widespread. Advanced Aircraft Design: Conceptual Design, Analysis and Optimization of Subsonic Civil Airplanes presents a quasi-analytical optimization approach based on a concise set of sizing equations. Objectives are aerodynamic efficiency, mission fuel, empty weight and maximum takeoff weight. Independent design variables studied include design cruise altitude, wing area and span and thrust or power loading. Principal features of integrated concepts such as the blended wing and body and highly non-planar wings are also covered. The quasi-analytical approach enables designers to compare the results of high-fidelity MDO optimization with lower-fidelity methods which need far less computational effort. Another advantage to this approach is that it can provide answers to “what if” questions rapidly and with little computational cost. Key features: Presents a new fundamental vision on conceptual airplane design optimization Provides an overview of advanced technologies for propulsion and reducing aerodynamic drag Offers insight into the derivation of design sensitivity information Emphasizes design based on first principles Considers pros and cons of innovative configurations Reconsiders optimum cruise performance at transonic Mach numbers Advanced Aircraft Design: Conceptual Design, Analysis and Optimization of Subsonic Civil Airplanes advances understanding of the initial optimization of civil airplanes and is a must-have reference for aerospace engineering students, applied researchers, aircraft design engineers and analysts.

Download or read book Aircraft Conceptual Design Synthesis written by Denis Howe and published by . This book was released on 2000 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aircraft Conceptual Design Synthesis means design by fitness-for-purpose. Design engineers can jump off from the point of given parameters and requirements – required performance, payloads and other factors. This is the first book for the aeronautical designer devoted to guiding the reader through this highly effective conceptual design synthesis process. This forms the procedure for the initial stage of the aircraft design process – the interpretation of a requirement into the preliminary layout. A logical design sequence is developed utilizing original modules to represent propulsion, lift, drag, mass, and performance. Aircraft Conceptual Design Synthesis includes a disk of spreadsheets that provides core data. Unlike existing approaches, the design synthesis method can be applied to novel aircraft concepts. CONTENTS INCLUDE The design process Aircraft configuration Flight regime and powerplant considerations Fuselage layout Configuration of the wing Basic lift, drag and mass representations Performance estimation Parametric analysis and optimisation Analysis of concept design “This is an important landmark book and in my view will become a standard by which others will be compared” – Dr E C P Ransom, Kingston University, UK

Book excerpt: Abstract :Home-built aircraft make a large portion of today ́s aircraft used in general aviation. While most of these are piston powered, there is increasing interest for jet propelled, light personal jets. Typically, very experienced pilots who are bored of flying piston aircraft and who seek higher speeds with military-jet like feeling show an interest in this kind of aircraft. The following work did a market analysis, compares the different conceptual designs and addresses the design process. The result is a preliminary sizing of such an aircraft with selection of an engine. As a final outcome, two different configurations were evaluated in more detail and 3D-drawings were produced. The appendix covers some of the initial sizing methodology for subsystems, such as landing gear and fuel system. *****Abstract :Home-built aircraft make a large portion of today ́s aircraft used in general aviation.
