For small ships and leisure boats, gyroscopic couples from a wind turbine also need to be taken into account to prevent stability issues in a seaway. Navigating an alternative course: although the pressure is on for shipping to reduce emissions, there seems to be a surprisingly low level of activity in the area of renewable marine propulsion. Background and Theory For gyroscopic action to occur, the axis of the rotating body causes the axis of rotation to remain in the same direction so long as no external couple acts on the system. If a turning couple is applied to the axis, a gyroscopic couple is produced which turns the axis in a plane at right angles to the plane in which the applied couple acts. You can plot a graph of the effect of change in boat heading on the Deviation, this is called a Deviation Curve. Deviation can be measured by ‘swinging the compass’, that is, checking the compass reading when the boat is on a known heading, round a ° series of headings, and plotting the resultant errors. gyroscope (jī`rəskōp'), symmetrical mass, usually a wheel, mounted so that it can spin about an axis in any spinning, the gyroscope has special properties. Many spinning objects exhibit some of these properties; the rotation of the earth about its axis gives it the properties of a huge gyroscope.

It operates by seeking an equilibrium direction under the combined effects of the force of gravity and the daily rotation of Earth. Angular momentum is a vector quantity. It is derivable from the expression for the angular momentum of a particle Gyrocompass A gyrocompass is a type of non-magnetic compass which is based on a fast-spinning disc and rotation of the Earth (or another planetary body if used elsewhere in the universe) to automatically find geographical direction.
The chapters composing this book originally appeared as a series of articles in The Engineer during January, February, and March of the current year. The articles were written in the belief that many readers would welcome a clear and full, non-mathematical exposition of the gyroscopic compass, its theory and practical construction.
THE THEORY OF A GYROCOMPASS (K TEORII GIROKOMPASOV) PMM Vol No.5, pp. S17 V.N.

Koshliakov. A magnetic compass like the one created on the previous page has several problems when used on moving platforms like ships and airplanes. It must be level, and it tends to correct itself rather slowly when the platform turns.
Because of this tendency, most ships and airplanes use gyroscopic compasses instead. 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. In particular, the following gyroscope-type devices are considered: the directional gyroscope, the gyroscopic vertical, the stabilized gyroscopic platform, the laser gyroscope, the fiber-optic gyroscope, the piezoelectric gyroscope, the fork gyroscope, and the microgyroscope with a spinning disk and with a vibrating : Jan Awrejcewicz, Zbigniew Koruba.
Requirements for the guidance and control of ships, aircraft, spacecraft, submarines, and missiles have made development of the gyroscope—the spinning top—an important technology. This book provides the engineer, the navigator, and the student with theory and practical knowledge of how these instruments are made and how they function.

Gyroscopic instruments, a convenience for VFR flight, are an absolute necessity for IFR flight and provide a direct indication of an aircraft's attitude. Every aircraft is equipped with three gyroscopic instruments and comprise the attitude indicator, heading indicator, and turn coordinator.

Gyroscopic inertia: the gyro’s conservation of angular momentum (i.e., natural resistance to change in orientation with regard to its inertial frame of reference).
Gyroscopic precession: the gyro’s measured deviation in local frame of reference to the gyro’s fixed frame of reference. Gyroscopes Couple Introduction Whilst Gyroscopes are used extensively in aircraft instrumentation and have been utilised in monorail trains, the everyday impact of gyroscopic forces on our lives is unappreciated and significant.
The simple example. In Foucault used a gyroscope to demonstrate the Earth's rotation. The gyroscope wheel is in a double-axed gimbal mount, so that the force of gravity acts on the wheel's center of mass, and no torque is acting on the wheel.
Without torque to change its direction of motion a spinning gyroscope wheel will remain pointing in the same direction.

Ship’s magnetic conditions create magnetic compass deviations and sectors of sluggishness and unsteadiness.
Deviation is defined as deflection right or left of the magnetic meridian caused by magnetic properties of the vessel. A gyroscope is a wheel mounted in two or three gimbals, which are pivoted supports that allow the rotation of the wheel about a single axis.A set of three gimbals, one mounted on the other with orthogonal pivot axes, may be used to allow a wheel mounted on the innermost gimbal to have an orientation remaining independent of the orientation, in space, of its support.
Let the magnetic course be α. X is acting toward bow so its positive and Y toward ports so conventionally negative. From the figure it is clear that. X = α. Y= α.

17A6. Precession. The gyroscopic property referred to as precession may be demonstrated by applying a force to the gyroscope so as to tend to change the plane of rotation of the spinning wheel. If the gyroscopic wheel is spinning in the upward direction as indicated by the arrow B and a force is applied to turn the gyroscope about the horizontal axis (Figure ), it will be found.
