Are you a hero or a villain? Pick your path in Super You!, this action-packed, illustrated origin story where the reader – yes, that means YOU! – gets the power of flight and must decide, choice by choice, whether to use their abilities for good or evil. You thought you were in for an ordinary summer at science camp – that is, until you sneak into an off-limits area of the Center for Avian Science, get your hand scratched by a weird bird, and suddenly gain the power of flight! Now it's up to you to decide how to use the power: Will you fly out at night to save the day? Will you team up with the villainous Dr. Zeus, who bred the mutant bird and wants to take over the world with its powers? Or will you make the wrong choice and meet an ill-fated end? Follow the choices, pick your path, and fly toward your fate. This looks like a job for Super You!
Based on a 15-year successful approach to teaching aircraft flight mechanics at the US Air Force Academy, this text explains the concepts and derivations of equations for aircraft flight mechanics. It covers aircraft performance, static stability, aircraft dynamics stability and feedback control.
Annotation The measurement of performance during an airplane's flight, testing is one of the more important tasks to be accomplished during its development as it impacts on both the airplane's safety and its marketability. This book discusses performance for both propeller-driven and jet aircraft.
Fly an airplane at a set attitude, airspeed, and power setting, and it does precisely what it is supposed to—every time. This book tells why and how “flying by the numbers” works, and gives the flight-tested numbers for precision performance in 27 of America's favorite small aircraft. For aircraft not included in this list, the book provides exact cockpit procedures for nailing down the numbers for any other light airplane.
From an engineer and futurist, an impassioned account of technological stagnation since the 1970s and an imaginative blueprint for a richer, more abundant future The science fiction of the 1960s promised us a future remade by technological innovation: we’d vacation in geodesic domes on Mars, have meaningful conversations with computers, and drop our children off at school in flying cars. Fast-forward 60 years, and we’re still stuck in traffic in gas-guzzling sedans and boarding the same types of planes we flew in over half a century ago. What happened to the future we were promised? In Where Is My Flying Car?, J. Storrs Hall sets out to answer this deceptively simple question. What starts as an examination of the technical limitations of building flying cars evolves into an investigation of the scientific, technological, and social roots of the economic stagnation that started in the 1970s. From the failure to adopt nuclear energy and the suppression of cold fusion technology to the rise of a counterculture hostile to progress, Hall recounts how our collective ambitions for the future were derailed, with devastating consequences for global wealth creation and distribution. Hall then outlines a framework for a future powered by exponential progress—one in which we build as much in the world of atoms as we do in the world of bits, one rich in abundance and wonder. Drawing on years of original research and personal engineering experience, Where Is My Flying Car?, originally published in 2018, is an urgent, timely analysis of technological progress over the last 50 years and a bold vision for a better future.
"Much has been written about the famous conflicts and battlegrounds of the East during the American Revolution. Perhaps less familiar, but equally important and exciting, was the war on the western frontier, where Ohio Valley settlers fought for the land they had claimed -- and for their very lives. George Rogers Clark stepped forward to organize the local militias into a united front that would defend the western frontier from Indian attacks. Clark was one of the few people who saw the importance of the West in the war effort as a whole, and he persuaded Virginia's government to lend support to his efforts. As a result Clark was able to cross the Ohio, saving that part of the frontier from further raids. Lowell Harrison captures the excitement of this vital part of American history while giving a complete view of George Rogers Clark's significant achievements. Lowell H. Harrison, is a professor emeritus of history at Western Kentucky University and is the author or co-author of numerous books, including Lincoln of Kentucky, A New History of Kentucky, and Kentucky's Governors."
One small act of kindness ripples out to connect four kids in this stirring novel by the author of the beloved The Benefits of Being an Octopus. Libby comes from a long line of bullies. She wants to be different, but sometimes that doesn’t work out. To bolster herself, she makes a card with the message You are amazing. That card sets off a chain reaction that ends up making a difference in the lives of some kids who could also use a boost—be it from dealing with bullies, unaccepting families, or the hole that grief leaves. Receiving an encouraging message helps each kid summon up the thing they need most, whether it’s bravery, empathy, or understanding. Because it helps them realize they matter—and that they're not flying solo anymore.
By the late 1930s air power had dramatically altered the strategic balance in Europe. But the seeds of the new order had been sown in World War I, when fledgling military air forces first emerged as adjuncts to the traditional armed services. Military leaders soon recognised its value as an aerial scout. And before long, fast fighter planes armed with machine guns were ordered into battle to support the armies of both the Allies and the Central Powers.
