state of the art in aeronautical engineering has been continually accelerated by the development of advanced analysis and design tools. Used in the early design stages for aircraft and spacecraft, these methods have provided a fundamental understanding of physical phenomena and enabled designers to predict and analyze critical characteristics of new vehicles, including the capability to control or modify unsatisfactory behavior. For example, the relatively recent emergence and routine use of extremely power- ful digital computer hardware and software has had a major impact on design capabilities and procedures. Sophisticated new airflow measurement and visualization systems permit the analyst to conduct micro- and macro-studies of properties within flow fields on and off the surfaces of models in advanced wind tunnels. Trade studies of the most efficient geometrical shapes for aircraft can be conducted with blazing speed within a broad scope of integrated technical disciplines, and the use of sophisticated piloted simulators in the vehicle development process permits the most important segment of operations—the human pilot—to make early assessments of the acceptability of the vehicle for its intended mission. Knowledgeable applica- tions of these tools of the trade dramatically reduce risk and redesign, and increase the marketability and safety of new aerospace vehicles.

Flight Mechanics Modeling and Analysis comprehensively covers flight mechanics and flight dynamics using a systems approach. This book focuses on applied mathematics and control theory in its discussion of flight mechanics to build a strong foundation for solving design and control problems in the areas of flight simulation and flight data analysis. The second edition has been expanded to include two new chapters and coverage of aeroservoelastic topics and engineering mechanics, presenting more concepts of flight control and aircraft parameter estimation. This book is intended for senior undergraduate aerospace students taking Aircraft Mechanics, Flight Dynamics & Controls, and Flight Mechanics courses. It will also be of interest to research students and R&D project-scientists of the same disciplines. Including end-of-chapter exercises and illustrative examples with a MATLAB®-based approach, this book also includes a Solutions Manual and Figure Slides for adopting instructors. Features: • Covers flight mechanics, flight simulation, flight testing, flight control, and aeroservoelasticity. • Features artificial neural network- and fuzzy logic-based aspects in modeling and analysis of flight mechanics systems: aircraft parameter estimation and reconfiguration of control. • Focuses on a systems-based approach. • Includes two new chapters, numerical simulation examples with MATLAB®-based implementations, and end-of-chapter exercises. • Includes a Solutions Manual and Figure Slides for adopting instructors.

Indoor flight with light models offers fascinating possibilities thanks to new micro-components and construction methods. The variety of materials (balsa, polystyrene, boron fibres, Mylar film, etc.) makes possible not only classic indoor flight with rubber propulsion but also electric indoor flight with new components (coreless motors, micro-RC equipment, tiny lithium polymer cells). A section is also devoted specifically to supercapacitor propulsion. The most important feature of all light models with weights of typically 1.5 to 10 grams is the slow flying at walking pace. The risk of damage is correspondingly low. Another advantage of indoor flying is that it can be practised all year round, regardless of the weather. The door is wide open for school projects. The author has held numerous workshops in schools and at the Deutsches Museum, as well as supervising teachers in Saalflug projects. He has also been a participant in numerous international and national competitions. The book helps to overcome the initial threshold of lightweight construction with detailed instructions and construction plans. It accompanies the model flyer, starting with simple models suitable for the beginner or for workshop instruction, up to competition performance models. Let yourself "decelerate" and enjoy the slowly floating flying objects! From the content: • History of Indoor flight • Model classes • Materials • Working techniques • Rubber propulsion • Electric propulsion • CO2 drive • Supercapacitors • Balloon launch • Air wave • Flight practice • Propeller • Entry-level models • Styrofoam models • Construction plans

N.A.C.A. models 74, 74-A, and 75 were tested in the N.A.C.A. tank to determine their hydrodynamic properties and in the N.A.C.A. 20-foot wind tunnel to determine their aerodynamic properties. The forms of these models were derived from that of a solid of revolution having a lowe air drag, and the departures from the form of this low-drag body were the minimum considered to give satisfactory take-off performance. Model 74 has a rounded bottom with flared chines, a transverse step wit ha small fairing aft of it, and a pointed afterbody. Model 74-A has the same forme except for the removal of the fairing aft of the step. Model 75 has a pointed step and a horizontal afterbody derived from the form of the N.A.C.A. model 35 series.

The air transport industry is highly vulnerable to environmental changes as was seen when the recent COVID-19 pandemic caused most airline operations to cease. However, for decades airlines have been collapsing around the globe as the business of managing airline operations has become stressed due to price competition. This is detrimental to air carriers since air transport products and services are the same. Moreover, it impacts other industries such as tourism, hotels, and restaurants, which contribute to the derailment of economic and social activities. Thus, it is essential to determine new practices and strategies that can allow air transport management to be enriched and to flourish. Global Air Transport Management and Reshaping Business Models for the New Era provides a comprehensive collection of knowledge on the new era of business management on air transport. It provides strategies, technologies, and tools used in the reshaping of the air transport business model. Covering topics such as customer experience, robotic process automation, and airline alliances, this major reference work is an essential resource for airline managers, supply chain specialists, air transport managers, students and faculty of higher education, libraries, researchers, economists, government officials, and academicians.
