Book excerpt: The Preliminary Aircraft Design and Optimisation tool, PrADO, is an in-house program of the Institute of Aircraft Design and Lightweight Structures, TU Braunschweig, Germany, which covers a wide range of aspects of aircraft preliminary design. An initial aircraft concept serves as a basis for various analysis modules. Each module is designated to fulfil one special task e.g. aerodynamic analysis, estimation of structural mass, etc. The available methods grouped within those modules range from statistical methods to physics based models. From an aircraft developer’s point of view PrADO is used within both, the conceptual and the preliminary design phase. The aim of this thesis is to introduce methods and methodologies to aircraft conceptual and preliminary design, more precisely to PrADO, that allow to judge supersonic aircraft concepts. Therefore, the aerodynamic analysis module, the structural analysis module and the propulsion module are extended. An inviscid flow solver is integrated to obtain aerodynamic coefficients. The calculated data serves as input to other analysis modules of PrADO. While the aerodynamic analysis module solely uses the outer geometry of the aircraft, the structural analysis module uses its internal structural layout as additional input to a herein developed finite element model generator. The distribution of secondary mass, fuel loading and payload distributions as well as loads for ground cases and trimmed flight cases are taken from the PrADO database, whereas the aerodynamic forces are calculated by solving the inviscid Euler equations. The model serves as basis for structural sizing and consequently the estimation of structural mass. The purpose of the propulsion module is to size the engine, to calculate the engine performance map and to provide reliable mass data based on the thermodynamic cycle. PrADO provides various models for the analysis of turbojet, turbofan and turboprop engines. It is extended by a turbofan engine with mixed exhaust flow. The verification of the aerodynamic data is solely based on its expected qualitative distribution, since data from higher order methods was not available for the time being. The results compare well with the expected behaviour. The structural sizing process is verified based on an example from literature. The results of the developed sizing algorithm show extraordinary agreement with the reference data. The extended aircraft design process is finally applied to an aircraft from the European research project HISAC. The results compare well with global aircraft data. An excursion into the field of temperature effects in supersonic flight is provided, since no relevant literature is found on the topic with regard to conceptual and preliminary aircraft design. The results are translated into helpful information on the material selection process in the stage of aircraft pre-design. Eventually, the tool chain is applied to analyse a supersonic business jet and the results are presented. Based on the results of this basic design, a parameter study is conducted. A combination of cruise Mach number and design range is varied. Global design parameters show expected sensitivity to such variations. Das am Institut für Flugzeugbau und Leichtbau der TU Braunschweig entwickelte Programm PrADO (Preliminary Aircraft Design and Optimisation tool) stellt Werkzeuge zur Analyse und Beurteilung von Flugzeugen in der Konzept- und Vorentwurfsphase bereit. Basis der Analyse ist ein erstes Flugzeugkonzept. Jedes Entwurfsmodul gruppiert Methoden zur Lösung einer Teilaufgabe im Vorentwurfsprozess, z.B. Bestimmung der aerodynamischen Beiwerte oder Masseanalyse. Die vorhandenen Methoden reichen von einfachen Abschätzungsformeln bis hin zu physikalisch begründeten Berechnungsmodellen. Die Zielsetzung dieser Arbeit ist es, Methoden in die Konzept- und Vorentwurfsphase, genauer in das Programm PrADO, einzuführen, welche die Bewertung von Überschallflugzeugen ermöglichen. Daher werden die aerodynamischen, strukturmechanischen und antriebsspezifischen Entwurfsmodule erweitert. Zur Berechnung der aerodynamischen Beiwerte wird ein Euler-Verfahren eingesetzt. Die Ergebnisse stehen anderen Entwurfsmodulen in Form von Kennfeldern zur Verfügung. Das strukturmechanische Modell benötigt, neben der äußeren Geometrie, auch den inneren Aufbau des Flugzeugs. Diese Daten bilden die Grundlage eines Finite-Elemente-Modells. Die Verteilung von Sekundärmassen, Kraftstoff und Nutzlast, sowie Lasten für Boden- und ausgetrimmte Flugfälle werden der PrADO-Datenbank entnommen. Die aerodynamischen Kräfte werden mit dem Euler-Verfahren berechnet und auf das Modell aufgeprägt. Das Modell bildet die Basis zur Strukturdimensionierung und somit der Berechnung der Strukturmasse. Die Aufgabe des Antriebsmoduls ist die Triebwerksgröße zu bestimmen, Triebwerkskennfelder bereitzustellen und die Masse des Antriebssystems zu berechnen. Das Modul wird um ein Zweikreis-Turbinenluftstrahltriebwerk mit Mischung von Primär- und Sekundärstrom ergänzt. Die qualitativen Verläufe der aerodynamischen Beiwerte entsprechen dem zu erwartenden Verhalten. Für einen quantitativen Vergleich stehen keine Vergleichsdaten aus höherwertigen Verfahren zur Verfügung. Das erweiterte Strukturanalysemodul wird auf ein Literaturbeispiel angewendet. Die Ergebnisse zeigen eine sehr gute Übereinstimmung mit den Daten. Nach der Verifikation der Einzelmodule wird der Gesamtentwurfsprozess an einem Flugzeug des europäischen Projekts HISAC überprüft. Die globalen Entwurfsergebnisse zeigen sehr gute Übereinstimmungen mit den verfügbaren Referenzdaten. Die im Überschallflug auftretenden thermischen Aspekte werden in einem kurzen Exkurs behandelt. Dies erscheint notwendig, da zu diesem Thema keine, auf den Vorentwurf bezogene Literatur gefunden wurde. Die Ergebnisse geben dem Ingenieur erste Hinweise zur Materialauswahl im Rahmen der Konzept- und Vorentwurfsphase. Schlussendlich wird der erweiterte Entwurfsprozess zum Entwurf eines Überschallgeschäftsreiseflugzeugs genutzt. Auf Basis der gewonnenen Erkenntnisse wird eine Parameterstudie durchgeführt. Die Sensitivitäten der globalen Entwurfsparameter bei Änderungen von Machzahl und Reichweite werden gut wiedergegeben.

Available in PDF, EPUB and Kindle. Book excerpt: Written with students of aerospace or aeronautical engineering firmly in mind, this is a practical and wide-ranging book that draws together the various theoretical elements of aircraft design - structures, aerodynamics, propulsion, control and others - and guides the reader in applying them in practice. Based on a range of detailed real-life aircraft design projects, including military training, commercial and concept aircraft, the experienced UK and US based authors present engineering students with an essential toolkit and reference to support their own project work.All aircraft projects are unique and it is impossible to provide a template for the work involved in the design process. However, with the knowledge of the steps in the initial design process and of previous experience from similar projects, students will be freer to concentrate on the innovative and analytical aspects of their course project. The authors bring a unique combination of perspectives and experience to this text. It reflects both British and American academic practices in teaching aircraft design. Lloyd Jenkinson has taught aircraft design at both Loughborough and Southampton universities in the UK and Jim Marchman has taught both aircraft and spacecraft design at Virginia Tech in the US.* Demonstrates how basic aircraft design processes can be successfully applied in reality* Case studies allow both student and instructor to examine particular design challenges * Covers commercial and successful student design projects, and includes over 200 high quality illustrations

This book was released on 2012-01-19 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inhaltsangabe:Introduction: On the 26th of August 2010 the new ultra-large-cabin ultra-long-range Gulfstream G650 business jet reached Mach 0.995 during its flight test campaign (1). This is almost the speed of sound (Mach 1) and inspires one to say, why not fly faster than the speed of sound! Reduce travelling time in the commercial business aviation segment. This is, however not a completely new vision. Many companies and research facilities have already spent a lot of time and investment in studies to investigate the feasibility of supersonic flight. Entry Into Service (EIS) for the new Gulfstream G650 is scheduled for 2012. In the following the main performance parameter of the G650 aircraft will be summarised. The parameters range, cruise speed, MTOW, etc. have been selected and serve as a basis to allow an appropriate comparison between the G650 as the latest high end Subsonic Business Jet and potential in future Supersonic Business Jets (SSBJ) within this subject Master Thesis. With the impressive maximum range of nearly 13,000 km the G650 can connect Dubai with New York or London with Buenos Aires within almost 14 hours. Maximum Range @ Normal Cruise Speed: 7,000 nm/12,964 km. Normal Cruise Speed Mach: 0.85/904 km/h. Mmo (Maximum Operating Mach Number): Mach 0.925. Maximum Cruise Altitude: 51,000 ft/15,545 m. Maximum Takeoff Weight (MTOW): 99,600 lb/45,178 kg. Maximum Fuel Weight: 44,200 lb/20,049 kg. Passengers: 11 18. Price: appr. 60-70 million USD. Gulfstream business rival Bombardier Aerospace also announced in October 2010 two new high end models, the Global 7000 and 8000 with a maximum range of 7,300 nm (13,520 km) and 7,900 nm (14,631 km) at cruise speed Mach 0.85. Entry Into Service is scheduled for 2016 (Global 7000) and 2017 (Global 8000). A comprehensive overview of business jets in service and in development is given in attachment 13.1. A Supersonic Business Jet flying at Mach 2 cruise speed could virtually halve the travelling time, which would enormously enhance the mobility and flexibility. In order to achieve this ambition a paradigm shift is required. New technologies must be established, the impact on the environment must be understood and minimised, existing regulations must be changed to permit overland flight restrictions and the product still needs to be economically viable. All of the above aspects must be considered and will be subject for discussion within this Master Thesis (See also figure [...]

Available in PDF, EPUB and Kindle. Book excerpt: The gripping true tale of a devastating plane crash, the investigation into its causes, and the race to prevent similar disasters in the future. On July 25, 2000, a Concorde, the world's fastest passenger plane, was taking off from Charles de Gaulle Airport in Paris when it suddenly burst into flames. An airliner capable of flying at more than twice the speed of sound, the Concorde had completed 25 years of successful flights, whisking wealthy passengers--from diplomats to rock stars to corporate titans--between continents on brief and glamorous flights. Yet on this fateful day, the chartered Concorde jet, en route to America, crashed and killed all 109 passengers and crew onboard and four people on the ground. Urgent questions immediately arose as investigators scrambled to discover what had gone wrong. What caused the fire? Could it have been prevented? And, most urgently, was the Concorde safe to fly? Last Days of the Concorde addresses these issues and many more, offering a fascinating insider's look at the dramatic disaster, the hunt for clues, and the systemic overhauls that followed the crash.

Available in PDF, EPUB and Kindle. Book excerpt: The origin of Aerodynamic Design of Transport Aircraft stems from the time when the author was appointed part-time professor in the Aerospace Faculty of Delft University of Technology. At the time his main activities were those of leading the departments of Aerodynamics, Performance and Preliminary Design at Fokker Aircraft Company. The groundwork for this book started in 1987 as a series of lecture notes consisting mainly of pictorial material with a minimum of English explanatory text. After the demise of Fokker in 1996 one feared that interest in aeronautical engineering would strongly diminish. As a result of this, the course was discontinued and the relationship between the author and the faculty came to an end. Two years later the situation was reappraised, and the interest in aeronautical engineering remained, so the course was reinstated with a former Fokker colleague Ronald Slingerland as lecturer. The lecture notes from these courses form the foundation of this publication.
