This book was released on 2016-07-05 with total page 162 pages. Available in PDF, EPUB and Kindle. 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.

This book was released on 1966 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: An approximate method for calculating climb and acceleration performance of an air-breathing aircraft has been developed. Basically, the method involves linearization of the equations of motion to obtain closed-form expressions for the desired performance parameters. These expressions are applied over finite velocity intervals where the aerodynamic, propulsion, and flight-path parameters are assumed to be constant. The method is extended by a rapidly convergent iteration procedure to estimate the climb performance for a flight path limited by sonic-boom considerations. Typical examples are presented where the performance is estimated for an air-breathing boost mission to hypersonic speeds and for a complete supersonic-transport mission. The examples illustrate the simplicity of the method and show that the estimated performance is in good agreement with the results of a numerical integration of the equations of motion. The application of the approximate method to these examples indicates the utility of the method for producing performance estimates suitable for preliminary airframe design, sizing studies, propulsion-system evaluation, and cursory heat-transfer and inlet-flow-field determinations along a flight path. In order to increase the utility of the method further, nomograms are presented which provide rapid solutions to the approximate performance equations.
