Why Do Airplanes Have Tails? by Diana Cash Lennon Pdf

"Plane!"""a word squealed in delight by toddlers who hear, look up, and see a big gray object, a jet, sometimes leaving a billowy trail of white smoke (vapor), flying overhead. What is it? How did it get up there when I am down here? Can you take me to see a real plane? Can I touch it? Can we go inside? Can I ride in one? The wonders of the airplane never cease to amaze us. Endless questions come from our fascination with airplanes and flight. What is an airplane? Is an airplane any different from an aircraft? Why do they look different from each other? Can they fly without power? What are all the different parts of a plane called? Why Do Airplanes Have Tails? will take the reader from top to bottom, from left to right, from inside to outside, and in between, discovering a light aircraft and its basic parts. To be sure, they are complicated pieces of machinery. However, they operate under simple principles and with its many parts operating together, each contribute to lifting this piece of metal (or wood or composite) into the air. The language of airplanes is straightforward. When visual differences of airplanes are pointed out, it sometimes becomes obvious and even logical as to why they are called what they are called, whether a biplane, a high-wing, a low-wing, or even a three-wing. Many airplanes have made history""the Concorde, the Wright Flyer, the Voyager, the Spruce Goose, the Harrier jet, and the Spirit of St. Louis to name a few. There is a story behind the creation of each of these airplanes. Airplanes also have jobs""the airliner, the crop duster, the fire plane, the weather plane, and the exhibition plane, along with others""each designed and used for a specific purpose. Don't wait""read and get answers to what you've been wondering about airplanes! David Stanley was a 16-year-old Lafayette High gifted student when I met him and he was asked to illustrate this book. He gladly accepted and 14 illustrations were hand-drawn. We took field trips to airports and hangers and I took photos from which he used to illustrate.

Preliminary Flight Research on an All-movable Horizontal Tail as a Longitudinal Control for Flight at High Mach Numbers by Harold F. Kleckner Pdf

Summary: The NACA is conducting flight tests of an all-movable horizontal tail installed on a Curtiss XP-42 airplane because of its possible advantages as a longitudinal control for flight at high Mach numbers. The results are presented for some preliminary tests in the low-speed range for which the tail was very closely balanced aerodynamically and a bobweight was used to obtain stable stick-force variations with speed and acceleration. For these tests, the tail was hinged at 0.24 chord and was tried with two arrangements of servotab control. The elevator control was found to be unsatisfactory with the control arrangements tested. Although there were sufficient variation of stick force with acceleration in steady turns and a stable stick-force variation with speed, the near-zero variation of stick force with stick deflection resulted in an extremely sensitive control that required continuous attention in order to avoid motions of the airplane due to inadvertent movements of the control stick. For subsequent tests, the servotabs are being connected as geared unbalancing tabs in order that more conventional elevator hinge-moment characteristics may be obtained. The expected advantages of the all-movable tail with a control system utilizing tabs would of course be limited to flight at Mach numbers below those for which severe compressibility effects are encountered on the tail itself. For higher Mach numbers, the all-movable tail would require an irreversible power-boost control in order to handle the large hinge-moment increases that are expected.

The Influence of Vertical-tail Design and Direction of Propeller Rotation on Trim Characteristics of a Twin-engine-airplane Model with One Engine Inoperative by Marvin Pitkin,John W. Draper,Charles V. Bennett Pdf

Summary: Tests have been made in the Langley free-flight tunnel to determine the influence of mode of propeller rotation and vertical-tail design upon the trim characteristics of a model of a twin-engine airplane with one engine inoperative. The test model was mounted on a trim stand, which allowed freedom in roll and yaw under conditions simulating those required by the NACA and the Army Air Forces for asymmetric-power operation in flight. The seven vertical-tail designs tested included three tails of low aspect ratio and of different area, one twin tail of low aspect ratio, two tails of high aspect ratio and with different rudder areas, and one all-movable tail of high aspect ratio equipped with a linked tab. All tests were made with the flaps down.

Stability and Control of Airplanes and Helicopters by Edward Seckel Pdf

Stability and Control of Airplanes and Helicopters deals with aircraft flying qualities that determine the stability and control of airplanes and helicopters. It includes problems based on real aircraft, selected to represent the gamut from simple to complicated, and from conventional utility designs to futuristic research types. Many of these problems involve comparison of theory and experiment to demonstrate their mutual relationship. Comprised of 25 chapters, this book begins with a discussion on the aerodynamics of the component parts related to the lift and moment characteristics of an airplane, including wings and associated accessories; bodies such as fuselages, nacelles, and tip tanks; and control surfaces. The reader is then introduced to some mathematical techniques for linear differential equations; steady flight at different speeds; and stick force and control-free stability. Subsequent chapters focus on flaps and high-lift devices; power and compressibility effects; and the manner in which the aircraft responds to the application of control. Aeroelasticity and longitudinal equations of motion are also examined. This monograph is intended for undergraduate and graduate students taking modern engineering courses.

Summary of Spin Technology as Related to Light General-aviation Airplanes by James S. Bowman Pdf

A summary was made of all NASA (and NACA) research and experience related to the spin and recovery characteristics of light personal-owner-type general-aviation airplanes. Very little of the research deals with light general-aviation airplanes as such, but many of the airplanes and models tested before and during World War II were similar to present-day light general-aviation airplanes with regard to the factors that are important in spinning. The material is based mainly on the results of spin-tunnel tests of free-spinning dynamically scaled models of about 100 different airplane designs and, whenever possible, includes correlation with full-scale spin tests. The research results are discussed in terms of airplane design considerations and the proper use of controls for recovery.

Why Don't Jumbo Jets Flap Their Wings? by David Alexander Pdf

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.

Effects of Wing Position and Vertical-tail Configuration on Stability and Control Characteristics of a Jet-powered Delta-wing Vertically Rising Airplane Model by Powell M. Lovell,Lysle P. Parlett Pdf

An investigation has been conducted to determine the effects of wing position and vertical tail configuration on the stability and control characteristics of a jet-powered delta-wing vertically rising airplane model. A ducted-fan powerplant was used because there was no hot-jet powerplant of sufficiently small size and adequate reliability available. In addition to conventional flap-type control surfaces on the wings and vertical tails, the model had jet-reaction controls provided by movable eyelids at the rear of the tail pipe and by air bled from the main duct and exhausted through movable nozzles near the wing tips. The investigation consisted of flight and force tests of three model configurations: a high wing with a top-mounted vertical tail, a high wing with top- and bottom-mounted vertical tails, and a low wing with the top-mounted vertical tail. The flight tests, which were made in the Langley full-scale tunnel, represented slow constant-altitude transitions from hovering to normal unstalled forward flight.
