In this delightful Read & Listen ebook, when a strange egg appears in their nest, Mr. and Mrs. Bird kindly take it upon themselves to raise the "baby bird" inside. But when the egg hatches, the Birds are in for a big surprise—"Junior" is the oddest-looking baby bird they've ever seen—with big, long jaws full of teeth and an appetite to match. In fact, he looks more like a baby alligator than a baby bird! Nevertheless, the devoted Birds run themselves ragged feeding Junior until he gets so big, he must leave the nest or it will collapse underneath him. But how can Junior fly without wings? To the delight of the Birds—and readers!—the dilemma is solved when Junior takes off from a branch overlooking a pond. This ebook includes Read & Listen audio narration.

Following the advice of family members, a young bird learns to fly and tells other birds that to fly, they need only to flap their wings and try.

What do a bumble bee and a 747 jet have in common? It's not a trick question. The fact is they have quite a lot in common. They both have wings. They both fly. And they're both ideally suited to it. They just do it differently. Why Don't Jumbo Jets Flap Their Wings? offers a fascinating explanation of how nature and human engineers each arrived at powered flight. What emerges is a highly readable account of two very different approaches to solving the same fundamental problems of moving through the air, including lift, thrust, turning, and landing. The book traces the slow and deliberate evolutionary process of animal flight--in birds, bats, and insects--over millions of years and compares it to the directed efforts of human beings to create the aircraft over the course of a single century. Among the many questions the book answers: Why are wings necessary for flight? How do different wings fly differently? When did flight evolve in animals? What vision, knowledge, and technology was needed before humans could learn to fly? Why are animals and aircrafts perfectly suited to the kind of flying they do? David E. Alexander first describes the basic properties of wings before launching into the diverse challenges of flight and the concepts of flight aerodynamics and control to present an integrated view that shows both why birds have historically had little influence on aeronautical engineering and exciting new areas of technology where engineers are successfully borrowing ideas from animals.

Flapping wing vehicles (FWVs) have unique flight characteristics and the successful flight of such a vehicle depends upon efficient design of the flapping mechanisms while keeping the minimum weight of the structure. Flapping Wing Vehicles: Numerical and Experimental Approach discusses design and kinematic analysis of various flapping wing mechanisms, measurement of flap angle/flapping frequency, and computational fluid dynamic analysis of motion characteristics including manufacturing techniques. The book also includes wind tunnel experiments, high-speed photographic analysis of aerodynamic performance, soap film visualization of 3D down washing, studies on the effect of wing rotation, figure-of-eight motion characteristics, and more. Features Covers all aspects of FWVs needed to design one and understand how and why it flies Explains related engineering practices including flapping mechanism design, kinematic analysis, materials, manufacturing, and aerodynamic performance measures using wind tunnel experiments Includes CFD analysis of 3D wing profile, formation flight of FWVs, and soap film visualization of flapping wings Discusses dynamics and image-based control of a group of ornithopters Explores indigenous PCB design for achieving altitude and attitude control This book is aimed at researchers and graduate students in mechatronics, materials, aerodynamics, robotics, biomimetics, vehicle design and MAV/UAV.

Do you feel happy? Sad? Silly? Angry? This simple book helps children and parents talk about feelings, and includes a Feelings Faces Poster! With simple, sparse language, and bright, expressive illustrations, Lizzy Rockwell introduces very young readers to a wide range of emotions. Detailed art encourages identification and discussion of the different characters' emotional reactions, and serves as a springboard for discussion on emotional intelligence, self-regulation, and coping skills. The playground is the perfect place to witness lots of different feelings! A girl is happy when playing with a puppy. Another girl is angry when a boy knocks over her drink. And the boy is sorry. Readers will learn to identify feelings in themselves and in others in this simple, but clever book by a prominent preschool nonfiction author-illustrator. Beautiful, detailed spreads show panoramic views of the playground action, while close-ups focus on specific incidents, body language, and facial expressions. The sparse text encourages children to describe the action and tell the story themselves, using context clues in the art and their own understanding of the emotions portrayed. Turn the dust jacket around for a beautiful Feelings Faces poster, which collects the emotions portrayed in the book in one long spread!
