Q&A for aircraft pilots, mechanics, and enthusiasts. Inspired by this question, I would like to know what the pro's and con's of the mostly used vacuum-gyro and the less used high-pressure-gyro is. Richard Hallion in his book, Legacy of Flight, also states that a Gyrocompass (Directional Gyro) was installed in the plane, but the cockpit instrument panel shown in his book has a somewhat different layout from that in the NY Times photograph. During the test flights preceding the blind flight, different instrument configurations had been tried.
In this chapter, first a historical outline of the theory of gyroscopes is given. Elements of gyroscope classification are introduced, and then the evolution of the gyroscope concept is presented. What are the various power sources that may be used to power the gyroscopic instruments in an airplane? (FAA-H) In some airplanes, all the gyros are vacuum, pressure, or electrically operated; in others, vacuum or pressure systems provide the power for the heading and attitude indicators, while the electrical system provides the power.
Gyroscopic Instruments in Aircraft. Even the most basic aircraft trainer includes gyroscopic instruments, due to their overwhelming importance for flight and three most critical of these instruments are the artificial horizon, heading indicator, and turn indicator.

Advisory Group for Aerospace Research and Development. Flight Mechanics Panel.]. Several flight instruments utilize the properties of a gyroscope for their operation.
The most common instruments containing gyroscopes are the turn coordinator, heading indicator, and the attitude indicator. To understand how these instruments operate requires knowledge of the instrument power systems, gyroscopic principles, and the operating principles of each instrument.
A self-contained text, the book starts from basic theoretical concepts of motion and mechanics and works through the instrument theory toward practical applications. There is extensive material in the later chapters on the design and testing of gyroscopic instruments.
Flight without reference to a visible horizon can be safely accomplished by the use of gyroscopic instrument systems; These systems include attitude, heading, and rate instruments, along with their power sources; These instruments include a gyroscope (or gyro) that is a small wheel with its weight concentrated around its periphery.

Vacuum-Driven Attitude Gyros. The attitude indicator, or artificial horizon, is one of the most essential flight instruments. It gives the pilot pitch and roll information that is especially important when flying without outside visual references.
The attitude indicator operates with a gyroscope. Gyrodynamics and Its Engineering Applications deals with the engineering applications of gyrodynamics in a manner that stresses the physical concepts.
Topics covered range from the kinematics of rigid bodies to frames of reference, along with moments and products of inertia.
Gyro-verticals and the gyrodynamics of machines are also considered. electronic flight instrument systems integrate many individual instruments into a single presentation called a primary flight display (PFD). Since all flight instruments are combined in one integrated electronic flight instrument system, a number of enhancements to conventional flight instruments.
Flight without reference to a visible horizon can be safely accomplished by the use of gyroscopic instrument systems and the two characteristics of gyroscopes, which are rigidity and precession.
These systems include attitude, heading, and rate instruments, along with their power sources. These instruments include a gyroscope (or gyro) that is a small wheel with its weight concentrated around.
gyroscopic systems and instruments. general. Most aircraft have several instruments that are traditionally driven by mechanical Gyros. These instruments assist in flying and navigation of an aircraft. These instruments are the Attitude Indicator (also known as the Vertical Gyro), the Directional Gyro, and the Turn and Bank Indicator.

A gyroscope (from Ancient Greek γῦρος gûros, "circle" and σκοπέω skopéō, "to look") is a device used for measuring or maintaining orientation and angular velocity.
It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself.
When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting. Electrically driven gyroscopes for aircraft Abstract: GYROSCOPIC instruments are given a place of prominence on the instrument panels of military and commercial aircraft.
They are among the “most used” of all the instruments and are necessary for blind flight since they serve as stable references in space when natural objects are not by: 4. Before the gyroscopic effects of the propeller can be understood, it is necessary to understand the basic principle of a gyroscope.
All practical applications of the gyroscope are based upon two fundamental properties of gyroscopic action - rigidity in space, and precession. The one in which we are interested for this discussion is precession.
Traditional gyroscopic flight instruments have been replaced by Attitude and Heading Reference Systems (AHRS) improving reliability and thereby reducing cost and maintenance. The function of an AHRS is the same as gyroscopic systems; that is, to determine which.
Early pumps were called wet pumps because of the use of engine oil to provide sealing, lubrication and cooling to the pump. this oil mixes with air that the pump draws through the vacuum-powered instruments, and is then blown through an oil separator.
Gyroscopic Instruments, Vacuum and Electrical Systems Robert French Version – 2/5/03 Gleim section Gyroscopic Instruments • Gyroscopic instruments contain a gyroscope and rely on the principle of rigidity in space.
A spun-up gyroscope will tend to maintain its 3-D orientation even when its harness is Size: 57KB. While the three main gyro instruments use the same principles, there are significant differences inside the cases.
The artificial horizon, for example, contains the gyro wheel spinning on the vertical axis. One basic gyroscopic concept is precession — any force applied to the gyro will result in movement of the gyro wheel 90 degrees out of phase.
Flight instruments are the instruments in the cockpit of an aircraft that provide the pilot with information about the flight situation of that aircraft, such as altitude, airspeed, vertical speed, heading and much more other crucial improve safety by allowing the pilot to fly the aircraft in level flight, and make turns, without a reference outside the aircraft such as the.

Traditional Gyroscope Function Gyroscopes function differently depending on their type. TraditionalFile Size: KB.This book was written as a response to a lack of publications offering easily understandable information on gyroscopes.
This book aims to fill the gap between dictionary definitions and the all too often highly mathematical books on gyroscopes. With the aid of illustrations you will be shown the principles of gyroscopes including precession and nutation, where and how gyroscopes are used.
