Taschenbuch. Condizione: Neu. Neuware - Aeronautical engineering explains why 800,000 pounds of Boeing 747 stays six miles above the ground at 550 miles per hour, held up by nothing but air. This book takes you from the four forces acting on a wing to the design of a complete aircraft. Ten chapters build in order, each resting on the one before it. The math appears where it does real work and gets explained when it shows up, so no engineering background is needed to follow the reasoning. Real aircraft carry the explanations throughout, from the U-2 and the F-16 to the Boeing 787 and the GE90 turbofan. The chapters work through: - The four forces, the International Standard Atmosphere, and why density altitude grounded regional jets in Phoenix when the temperature hit 120 degrees - The core aerodynamics equations of continuity, momentum, and energy, plus Reynolds number, dynamic similarity, and scale model testing in wind tunnels - Airfoil geometry, NACA section families, angle of attack, the stall, aspect ratio, and the planform choices behind sweep, taper, twist, and dihedral - Laminar and turbulent boundary layers, skin friction, form drag, and induced drag - Mach regimes, shock waves, critical Mach number, the area rule, and the aerodynamic heating that stretched Concorde's fuselage several inches at cruise - Spars, ribs, stringers, semi-monocoque construction, aluminum and titanium and carbon fiber, and how fatigue sets a limit on airframe life - Propeller blade theory, the Brayton cycle, turbofan bypass ratio, afterburners, thrust reversers, ramjets, and rockets - Range and endurance from the Breguet equations, plus takeoff roll, climb gradient, glide ratio, and landing distance - Static and dynamic stability, center of gravity limits, fly-by-wire control laws, autopilot and cockpit displays - The design spiral, certification and airworthiness standards, uncrewed aircraft, electric propulsion, and sustainable aviation fuels Written for three readers in particular: - Students heading into an aerospace program who want the whole picture before coursework breaks it into separate subjects - Pilots who follow procedures by habit and want the reasoning underneath them - Anyone who watches an airliner climb out and wonders what holds it up Each chapter closes with questions, and worked example responses sit in the back so you can check your reasoning rather than guess at it. A decade-by-decade timeline traces the field from Cayley's silver disc to electric flight, a glossary keeps every term in one place, and a further reading list points you toward the books worth picking up next. Once you reach the end, you'll be able to look at almost any flying machine and read it: the length of its wings, how far they sweep back, the size and placement of its engines, the shape of its tail. Every one of those is an answer to a problem covered in these pages.…

Taschenbuch. Condizione: Neu. Neuware - Dictatorships run on a small set of repeatable tactics. Learn to name them and the whole subject becomes readable, whether the regime in question is Stalin's Soviet Union or a government making headlines this week. The chapters take the machinery apart in order, moving from definitions through the tools of control to the way regimes finally end. Every idea arrives attached to a real case, drawn from Hitler's Germany, Mao's China, Kim Il-sung's North Korea, Mobutu's Zaire, and dozens of lesser-known governments in between. The machinery, chapter by chapter: - What separates an autocracy from an ordinary strict government, including the one test that cuts through the noise: can the people in power be removed through a process they don't control - Six routes to power, including the coup, the revolution, the fair election followed by the quiet dismantling of everything that made it fair, foreign imposition, and inheritance from father to son - How leader cults get built through portraits, statues, currency, and mass choreography, and the moments when the worship turns on the leader - Censorship, rewritten history, invented enemies, and the digital versions running on firewalls and paid troll operations - Secret police at work: the NKVD, the Gestapo, the Stasi, and Iran's SAVAK, plus how ordinary neighbors become informants - Purges, rotation, rival armies set to watch each other, and parliaments that never vote no - Patronage, the oil curse, planned shortages, crony capitalism, and stolen fortunes moved offshore while the country goes without - Why succession is the most dangerous moment any regime faces, and what a country does with its former torturers once the regime is gone The book assumes no background in political science. Terms get defined where they first appear, and where scholars disagree, the disagreement is shown honestly instead of smoothed over. That makes it workable for: - Students in government, history, and comparative politics courses - News readers trying to tell strict leadership apart from genuine autocracy - Anyone reading about the subject for the first time Five sections follow the final chapter. A historical timeline places major regimes side by side. Worked example answers let you check your own thinking against the end-of-chapter questions. A glossary defines every term used, from anocracy to the dictator's dilemma. A conclusion ties the threads together, and a works cited and recommended reading list points toward deeper study of any single regime or idea. Today, most of the world's population lives under governments more authoritarian than democratic, and that share has been climbing. These patterns are running right now, in real countries, shaping billions of lives. This book gives you the vocabulary, concepts, foundations, and frameworks to read the warning signs yourself.…
