Ship Gyroscope

2016-12-18 09:06:43 · answer #2 · answered by Anonymous · 0 0

In ships the gyroscope is used to stable the ships. Ship stabilizing gyroscopes are a technology developed in the 19th century and early 20th century and used to stabilize roll motions in ocean-going ships. It lost favour in this application to hydrodynamic roll stabilizer fins because of reduced cost and weight. However, more recently (since the 1990s) a growing interest in the device has reemerged for low speed roll stabilization of vessels. The gyroscope does not rely on the forward speed of the ship to generate a roll stabilizing moment and therefore has shown to be attractive to motor yacht owners for use whilst at an anchorage.
In roll-stabilized ships, a gyro senses the ship's roll, producing an electrical signal. A servo system amplifies the signal to drive some sort of roll effecter like "planes" (fins) mounted on the sides of the ship that tilt and oppose the roll. The added weight comes from the servo mechanism, hydraulics (if not an all-electrical servo) and planes, not from the insignificant weight of the gyro. In military applications it is more common to allow ship roll but provide a stable platform for tilt-sensitive equipment like weapons or radar dishes. The servos for these require far less power to run.
Earlier ship antiroll systems used direct gyro stabilization. The stabilization came from gyro precession torque. A large gyro wheel was mounted with its spin axis perpendicular to the roll (longitudinal) axis. Rolling would be opposed by the sizable angular momentum of the wheel. These were indeed heavy systems but only a percent or so of the weight of the large ships they were installed in.

There are 3 corrections needed to stabilize a ship (I assume you mean a rocketship).
Side-to-side, front-to-back, and roll. A gyroscope is not capable of all 3.

A gyroscope is a device for measuring or maintaining orientation, based on the principle of conservation of angular momentum. The essence of the device is a spinning wheel on an axle. The device, once spinning, tends to resist changes to its orientation due to the angular momentum of the wheel. In physics this phenomenon is also known as gyroscopic inertia or rigidity in space. Rotor, The journals of the rotor, being mounted in an inner gimbal or ring, Axle, Spinning wheel, All will have wear resistance steel.] cast steel-duly hardened. aluminium alloy-outer frame.
