Abstract

FIELD: power industry.

SUBSTANCE: method for increasing gyroscopic moment is aimed at increasing the inertia moment radius owing to decreasing the distance between centres of gravity of loads along rotation axis. Shape of loads in the form of wings creates aerodynamic force in addition to centrifugal force. Device for implementation of the method for increasing gyroscopic moment represents centrifugal accumulator of kinetic and potential energy, which has big value of gyroscopic moment and power input. It is reached owing to forced creation of precession of ends of its rotation axis with angular speed equal to angular speed of this rotation axis, location and trajectory of movement of movable loads made in the form of aerodynamic wings.

Description

Preferred areas of technology: energy, transport.

State of the art

The prototype of this invention are centrifugal flywheel energy storage.

Under the influence of external forces on the rotating batteries, creating a precession of their rotation axes, a resistance force arises, called the gyroscopic moment.

These properties of the flywheel are used to stabilize the position in space of various devices, in particular navigation devices, relative to the axis of rotation of the earth.

The formula of the gyroscopic moment for the prototype:

Where

M _g - variable gyroscopic moment,

m is the constant reduced mass,

R is the constant radius of the moment of inertia of the flywheel,

Ω _{p is the} variable angular velocity of rotation of the flywheel,

ω _p - variable angular velocity of the precession of the axis of rotation of the flywheel,

I - constant moment of inertia of the flywheel,

H _p - variable kinetic moment of the flywheel.

However, flywheel accumulators have relatively small specific values of the gyroscopic moment and the energy intensity of kinetic energy, which is associated with the limitation of the possibility of increasing the angular velocity.

Device operation

A centrifugal energy accumulator is rotationally driven by the engine 11.

The resulting centrifugal force of variable magnitude synchronously rotates the movable levers 6 with loads 7 of an aerodynamic shape, changing the value of the radius of inertia of the centers of gravity of the loads 7.

There is a variable in magnitude gyroscopic moment, which creates:

firstly, the precession of both ends of the axis 3 of the centrifugal accumulator with an angular velocity equal to the angular velocity of this axis, and the vertices of the cones outlined by the ends of the axis 3 are located at the center of gravity of the centrifugal accumulator;

secondly, inside the bodies of elastic energy accumulators 4, an alternating tensile stress arises, transmitted from the levers 6 through the pulleys 9 and cables 10.

Moreover, with increasing radius of the moment of inertia, the distance along the axis 3 between the centers of gravity of the cargo 7 decreases.

The aerodynamic shape of the loads 7 creates an aerodynamic force additional to the centrifugal force.
