Airplane Stability and Control
An informal history of the personalities and events surrounding the development of airplane stability and control.
Scientific and Technical Aerospace Reports
Lists citations with abstracts for aerospace related reports obtained from world wide sources and announces documents that have recently been entered into the NASA Scientific and Technical Information Database.
The Natural Law of Cycles
The Natural Law of Cycles assembles scientific work from different disciplines to show how research on angular momentum and rotational symmetry can be used to develop a law of energy cycles as a local and global influence. Angular momentum regulates small-scale rotational cycles such as the swimming of fish in water, the running of animals on land, and the flight of birds in air. Also, it regulates large-scale rotation cycles such as global currents of wind and water.James H. Bunn introduces concepts of symmetry, balance, and angular momentum, showing how together they shape the mobile symmetries of animals. Chapter 1 studies the configurations of animals as they move in a head-first directi...
Digital Apollo
The incredible story of how human pilots and automated systems worked together to achieve the ultimate achievement in flight—the lunar landings of NASA’s Apollo program As Apollo 11’s Lunar Module descended toward the moon under automatic control, a program alarm in the guidance computer’s software nearly caused a mission abort. Neil Armstrong responded by switching off the automatic mode and taking direct control. He stopped monitoring the computer and began flying the spacecraft, relying on skill to land it and earning praise for a triumph of human over machine. In Digital Apollo, engineer-historian David Mindell takes this famous moment as a starting point for an exploration of th...
The Theory of Propellers
Summary: A technical method is given for calculating the axial interference velocity of a propeller. The method involves the use of certain weight functions P, Q, and F. Numerical values for the weight functions are given for two-blade, three-blade, and six-blade propellers.
An Introduction to the Elements of Airplane Stability and Control
The subject of airplane stability and control has advanced much since the elements were first learned just over one hundred years ago. Those who discovered them built gliders and piloted them. College texts must teach far beyond the lessons of those early years, so only a few pages can be allocated, in college texts, to the basics upon which today¿s technology is based. This book presents only the basic elements of the subject and does not include the more advanced material needed for graduation from college. Rather it is intended as a primer that can be used to teach at the senior high school or college freshman level or as a college senior-level supplemental text. It seeks to preserve the early lessons and to explain clearly the fundamental physical phenomenon of inherently stable and controllable airplane flight Only a minimum level of mathematics is used so that these lessons may be easily understood by more junior students, laymen, private pilots, and aero modelers who may wish to comfortably read through the material presented.
Memorial Tributes
This is the thirteenth volume in the series of Memorial Tributes compiled by the National Academy of Engineering as a personal remembrance of the lives and outstanding achievements of its members and foreign associates. These volumes are intended to stand as an enduring record of the many contributions of engineers and engineering to the benefit of humankind. In most cases, the authors of the tributes are contemporaries or colleagues who had personal knowledge of the interests and the engineering accomplishments of the deceased.
The Supersonic Bone
“This profusely illustrated and thoroughly researched book conveys a wealth of information” about the USAF’s B-1 bomber (Aviation History Magazine). When the B-52 Stratofortress entered operational service with the US Air Force in 1955, work was already underway on defining its successor. The B-70 Valkyrie, a Mach 3 jet bomber, was one option. Although two XB-70A prototypes flew, the B-70 never went into production. Out of the subsequent Advanced Manned Strategic Aircraft program came the B-1A bomber, which flew at high speed and low altitude to evade enemy air defenses. But the B-1A was cancelled in favor of fitting the B-52 with cruise missiles. The B-1, known as the BONE, was revive...
