Aerodynamics and Aircraft Performance
Marchman, James F. III (2004, 2021)

Aerodynamics and Aircraft Performance, 3rd edition is a college undergraduate-level introduction to aircraft aerodynamics and performance. This text is designed for a course in Aircraft Performance that is taught before the students have had any course in fluid mechanics, fluid dynamics, or aerodynamics. The text is meant to provide the essential information from these types of courses that is needed for teaching basic subsonic aircraft performance, and it is assumed that the students will learn the full story of aerodynamics in other, later courses. The text assumes that the students will have had a university level Physics sequence in which they will have been introduced to the most fundamental concepts of statics, dynamics, fluid mechanics, and basic conservation laws that are needed to understand the coverage that follows. It is also assumed that students will have completed first year university level calculus sequence plus a course in multi-variable calculus. Separate courses in engineering statics and dynamics are helpful but not necessary. Any student who takes a course using this text after completing courses in aerodynamics or fluid dynamics should find the chapters of this book covering those subjects an interesting review of the material. The 236-page text was created specifically for use by undergraduate students in Aerospace Engineering and was based on Professor Marchman’s many years of experience teaching related subject matter as well as his numerous wind tunnel research projects related to aircraft aerodynamics and his personal experience as the owner and pilot of a general aviation airplane. It has been used at Virginia Tech and other universities. How to adopt or adapt this book

Aerospace Structures
Johnson, Eric R. (Kevin T. Crofton Department of Aerospace and Ocean Engineering in affiliation with Virginia Tech Publishing, 2022)

Aerospace Structures by Eric Raymond Johnson is a 600+ page text and reference book for junior, senior, and graduate-level aerospace engineering students. The text begins with a discussion of the aerodynamic and inertia loads acting on aircraft in symmetric flight and presents a linear theory for the statics and dynamic response of thin-walled straight bars with closed and open cross-sections. Isotropic and fiber-reinforced polymer (FRP) composite materials including temperature effects are modeled with Hooke’s law. Methods of analyses are by differential equations, Castigliano’s theorems, the direct stiffness method, the finite element method, and Lagrange’s equations. There are numerous examples for the response of axial bars, beams, coplanar trusses, coplanar frames, and coplanar curved bars. Failure initiation by the von Mises yield criterion, buckling, wing divergence, fracture, and by Puck’s criterion for FRP composites are presented in the examples. Professors, if you are reviewing this book for adoption in your course, please let us know by filling out this form. Instructors reviewing, adopting, or adapting parts or the whole of the text are especially encouraged to fill it out. The EPUB was released early May 2023.

This text is evolved from lecture notes by the author for junior and senior students in the aerospace engineering curriculum at Virginia Tech. The subjects covered in the book presume some knowledge of statics, dynamics of rigid bodies, mechanics of deformable bodies, and mechanical vibrations. Several practice exercises in the text require programming, and typically the students use Mathematica1 or MATLAB 2 software to complete them. Examples in the text were programmed in Mathematica. A first semester sequence for junior students includes chapters 1 through 6. Note that chapter 3 on thinwall bar theory maybe too mathematical for some students, but can be used as a reference for the applications of the theory provided in chapter 4. The important topic of work and energy is covered in chapter 5, and chapter 6 is devoted to the application of Castigliano’s theorems to trusses, beams, and frames. A second semester sequence for junior students includes topics selected by the instructor from chapter 7 on curved bars, and chapters 10 through 16. The influence of imperfection sensitivity on the buckling load of discrete systems is presented in chapter 10, followed by buckling of columns and plates in chapter 11. Article 11.2 is optional. Analysis for wing divergence is presented in the introduction to aeroelasticity in chapter 12. The methods of linear elastic fracture mechanics to predict critical loads for crack propagation is discussed in chapter 13. Design of a landing strut, and the optimal design of a spar subject to constraints on yielding, buckling and fracture are presented in chapter 14. Chapters 15 and 16 detail the direct stiffness method for trusses, beams and frames. Topics appropriate for senior students are in chapters 8, 9, 17, and 18, and initial post-buckling in article 11.2. The response of closed and open section bars fabricated from a fiber-reinforced polymer composite (FRP) is presented in chapter 8, and failure initiation of FRP bars is presented in chapter 9. The finite element method applied to the extension and bending of bars is presented in chapter 17, which includes transverse shear deformations. The topic of adaptive mesh refinement in article 17.2.4 is optional. Articles 18.1 to 18.4 cover the dynamic response of lumped mass models, eigenvalue problems, and Lagrange’s equations. The remainder of chapter 18 utilizes the finite element method for the dynamic response of beams, trusses, and frames. In this textbook analytical methods are developed for the response and failure of the primary structural components of aircraft. Newton's laws of motion, Hooke s law, and the first law of thermodynamics are the basis to model the thermoelastic response of thin-walled, straight bars and coplanar curved bars. Analytical methods include energy principles to develop Castigliano s theorems and to develop the cross-sectional material law for transverse shear and torsion. Stiffened shells typical of aircraft structures are analyzed with the thin-walled bar theory. Externally prescribed loads are due to accelerated flight and the thermal environment. Velocity-load factor (V-n) diagrams for maneuvers and gusts are described to evaluate flight loads. Initiation of failure is predicted by one of the following criteria: von Mises yield criterion for ductile metals; the critical load to cause buckling (failure by excessive displacements); fracture criteria for the critical stress to cause crack propagation; Puck’s criterion for the brittle failure modes in fiber-reinforced polymer composites (FRP). The subject of structural stability of discrete conservative systems introduces the methods of stability analysis, classification of bifurcation buckling problems, the concept of imperfection sensitivity, and snapthrough at a limit point. Static instability of an elastic column from pre-buckling equilibrium, buckling, and through initial post-buckling is presented in detail. Buckling of flat rectangular plates subject to compression and shear is presented in a qualitative way using the classic charts from the National Advisory Committee for Aeronautics (NACA). The analysis for the static instability of a wing in steady incompressible flow, or divergence, is part of the discussion of aeroelastic phenomena. - Results from linear elastic fracture mechanics (LEFM) are introduced to illustrate the relation between crack size and the stress to cause crack propagation. Airplane damage-tolerant design is based on LEFM such that subcritical length cracks do not grow to critical length between inspection intervals. - The incentive to study optimal design is illustrated by the example of an aluminum wing spar. The objective is to achieve minimum weight by a search for two design variables. Constraints on yielding, buckling, and fracture are evaluated with the thin-walled bar theory. - The analyses are developed for closed and open section bars made from fiber-reinforced polymer composites. The cross-sectional compliance matrix for bars with a closed cross-sectional contour and an open cross sectional contour include shear-extension coupling. The first ply failure envelope for a graphite epoxy circular tube subject to an axial force and torque is determined by Puck’s intralaminar criterion. Interlaminar failure, or delamination, is modeled with fracture mechanics, and the method is illustrated by analyses of standard fracture test specimens. - Numerical methods for static analysis begin with the direct stiffness method, which originated to model skeletal structures consisting of bars connected by joints. Applications include coplanar trusses, beams and coplanar frames. The finite element method is developed from the integral formulation of the ordinary differential equations of an axial bar and a beam. - Analyses for the linear elastic, dynamic response of axial bars, coplanar trusses, beams, and coplanar frames are presented using the finite element method and the mode-separation method. Hamilton’s principle and Lagrange’s equations are developed for discrete mechanical systems. - Numerous examples to illustrate the application of the structural analysis are presented in each chapter using either U.S. customary units. or SI units.

Applied Human Anatomy
Nolan, Michael F.; McNamara, John (Virginia Tech Publishing, 2022)

The structure of the human body is usually considered in courses in gross anatomy. These courses typically consist of lectures by the faculty, readings in assigned textbooks and the study of photographs and illustrations in human anatomy atlases. However, as student’s progress through the curriculum and move into the more clinical or practice oriented phases, many discover that the anatomical knowledge they actually need is somewhat different from the kind they possess. What many encounter is difficulty in applying their knowledge to a clinical setting. Applied Human Anatomy was created to better integrate material that is more often than not treated separately in contemporary health care curricula. It is hoped that through this integration students will develop a deeper and more lasting knowledge and understanding of human anatomy as they are likely to need it in the evaluation and management of patients. A print version is available for purchase on Amazon.
Applied Human Neuroanatomy
Nolan, Michael F.; McNamara, John P. (Virginia Tech Publishing, 2022-12-15)

This 155-page manual is comprised of two types of learning activities: 1. Free response fill-in-the blank questions focused of the facts and principles of neuroanatomy and neurophysiology that underpin the neurologic examination and specifically developed exercises that demonstrate how the facts and principles are related to the particular tests and procedures that comprise the neurologic examination. Free response questions form the bulk of the Neuroscience Review section of each chapter and are intended as a review of information previously or concurrently being learned regarding the structure, function and organization of the nervous system. Some questions focus on anatomical or physiological facts and relationships that help explain why certain techniques are performed as they are, such as why non-nociceptive tactile stimuli are required in order to activate nerve impulse transmission in the lemniscal system. Other questions are intended to revisit facts and concepts that are needed to properly interpret the elicited findings. 2. The application exercises of each chapter are designed to demonstrate how neuroanatomical and neurophysiological information is used in the design of particular clinical tests of neurologic function. The application exercises are also intended to help users learn how to perform and become comfortable with the various clinical maneuvers and tests that comprise the routine neurologic examination. An important outcome of performing these exercises is that, as a member of a learning group, each individual has the opportunity to experience the neurologic examination from the point of view of the subject (patient)—an experience that arguably provides insight and understanding that can be gained in no other way. The questions and exercises in the manual are designed as group learning exercises that might complement and reinforce learning acquired in more traditionally structured courses dealing with the clinical examination of a patient. The “group activity” approach, in which the student performs each exercise on a small number of “normal” subjects (classmates), is founded on the belief that the ability to recognize an abnormal finding on clinical examination requires a familiarity with the range of normal findings in the otherwise healthy population. This is particularly true for new learners who may be for the first time, learning about the structure and function of the nervous system. The clinical assessment of neurologic function is often viewed as an exercise involving difficult to master techniques that frequently generate difficult to interpret findings. The authors argue that the neurologic examination is a reasonable and logical exercise involving the clinical application of basic principles of neuroanatomy and neurophysiology. One of the goals in developing this manual is to convince the reader of the truth of this perspective. DOI: https://doi.org/10.21061/applied-human-neuroanatomy Table of contents 1. Sensory Systems 2.

Andrew currently teaches heart and lung physiology and pathophysiology at Virginia Tech Carilion School of Medicine, directs the heart and lung pathophysiology course and has also served as the departmental director of faculty development. In his two decades of teaching medical physiology, Andrew has regularly drawn upon his dyspnea research experience to generate an active, clinically focused approach to medical education. This book is part of that approach and supports students preparing for class with the basic information with the intention to apply and contextualize that information in a guided case-based classroom experience. Andrew has published numerous peer-reviewed research papers and book chapters about dyspnea and about contemporary medical education. He has also given keynote presentations, faculty workshops and international webinars to promote effective medical education for the modern adult learner. Accessibility note

Cell Biology, Genetics, and Biochemistry for Pre-Clinical Students
LeClair, Renee J. (Virginia Tech Carilion School of Medicine in association with Virginia Tech Publishing, 2021)

Cell Biology, Genetics, and Biochemistry for Pre-Clinical Students is an undergraduate medical-level resource for foundational knowledge across the disciplines of genetics, cell biology and biochemistry. This USMLE-aligned text is designed for a first-year undergraduate medical course that is delivered typically before students start to explore systems physiology and pathophysiology. The text is meant to provide the essential information from these content areas in a concise format that would allow learner preparation to engage in an active classroom. Clinical correlates and additional application of content is intended to be provided in the classroom experience. The text assumes that the students will have completed medical school prerequisites (including the MCAT) in which they will have been introduced to the most fundamental concepts of biology and chemistry that are essential to understand the content presented here. This resource should be assistive to the learner later in medical school and for exam preparation given the material is presented in a succinct manner, with a focus on high-yield concepts. The 276-page text was created specifically for use by pre-clinical students at Virginia Tech Carilion School of Medicine and was based on faculty experience and peer review to guide development and hone important topics.

Conducting Mixed-Methods Research: From Classical Social Sciences to the Age of Big Data and Analytics
Venkatesh, Viswanath; Brown, Susan; Sullivan, Yulia (Virginia Tech Publishing, 2023-12-19)
Scholars in the social sciences are increasingly expected to incorporate both quantitative and qualitative techniques and methods into their research. The growth of “mixed-methods” research is evident in social science disciplines ranging from psychology and management to marketing and information systems. This book is designed to provide principles, strategies, and guidance specifically for researchers in these disciplines so that they can use mixed-methods research more effectively. In thirteen chapters, Conducting Mixed-Methods Research takes readers through the research process, from defining research questions to writing articles using a mixed-methods approach. For those who are well trained in either qualitative or quantitative methods, the book shows them how to think about the purposes of mixed-methods research, design mixed-methods studies, and develop meta-inferences by integrating findings from both methods. Throughout, the discussion is grounded in examples taken from published research, carefully chosen to highlight best practices, thus opening a window into a broad body of mixed-methods research applications. A paperback print version (in color) is available for order here.

Stuart “Bart” Bartholomew (1925-2013) joined the Navy as an engineer after enrolling at NROTC programs at the University of Washington. He earned bachelors and master’s degrees in civil engineering from UC Berkeley and made his post-Navy civilian career in heavy industry. He worked for legendary dam builder, Harvey Slocum on Bull Shoals Dam in Arkansas; Bhakra Dam in Punjab, India; Karnaphuli Dam in Bangladesh; port and rail facilities in Port Hedland, Western Australia; several segments of the Bay Area Rapid Transit system in San Francisco and the East Bay; and numerous marine, bridge, transportation and tunneling projects in the Midwest and on the East Coast. He joined Fruin-Colnon Corporation, becoming a vice president and member of the board of directors before his retirement in the early 1980s. He was a Fellow and Life Member of the American Society of Civil Engineers and a member of both the Moles and Beavers heavy engineering construction associations for over 25 years and was honored by the Beavers with the annual Engineering Award for outstanding achievement in Heavy Engineering Construction. After retirement from industry he pursued a second career as a professor of Construction Management at California State University, Chico, during which time he wrote Construction Contracting.

Epidemiology is an openly licensed text designed for medical degree–seeking clinical students without a prior background in public health. Using sports medicine and injury prevention examples and applications, it aims to provide students with the basics of epidemiology terms and concepts and is intended to guide medical school students as they prepare for the USMLE Step 1 Exam and to transition from student to clinician. It includes an introduction to general concepts and terminology of epidemiology, study designs and their relationship to clinical questions, and the use of epidemiology in clinical diagnosis and screening of disease. Concluding sections of the book present sources of errors in epidemiologic studies, including bias, confounding, and effect modification. The book is notable for its use of accessible, inclusive figures and examples, and end-of-chapter study guides that summarize the chapter visually.

Fish, Fishing, and Conservation
Orth, Donald J. (Virginia Tech Department of Fish and Wildlife Conservation in association with Virginia Tech Publishing, 2023-06-14)

Fish, Fishing, and Conservation is a 389-page, peer-reviewed open textbook intended for undergraduate students who are exploring majors in Fish & Wildlife. It is also relevant to a general audience or for use in courses which explore social and ethical aspects of fish, fishing and conservation. People, places, and approaches to fishing are as varied as the diverse fish fauna that exist on the planet. As conservation planners recognize the value of substantial engagement of stakeholders in decision making and ineffectiveness of rigid top-down management approaches, Fish, Fishing, and Conservation asserts that all peoples must play a role in conservation. Through case studies, engaging narrative and graphics, and exercises, the text explores major motivations for fishing and non-fishing related values, responsible fisheries practices, the rights of all people to decide how to manage and conserve fish, their habitats, and how they are utilized in the context of overfishing as a pressing global problem for which appropriate solutions are not easily found nor implemented. Introductory chapters examine fish, fishing, and why fish matter and examine the role of values in driving conservation initiatives. Fish and their unique sensory capabilities are described along with a review of recent studies to examine issues of pain, sentience, and learning in fishes living in a foreign, underwater world. The text incorporates these new findings in conservation and management leading readers to evaluate and adopt suitable approaches to ethical reasoning which consider the welfare needs of wild and cultured fishes. Later chapters focus on the role of gender in fishing, conservation organizations, recreational fishing, and a focus on specific fisheries that reveal the principles of conservation and management as they play out in major controversies. Additionally, the textbook contains audio recordings of professional profiles by Virginia Tech students. These are linked at the beginning of each end-of-chapter Professional Profile.
