Types of inertial propulsions.

Type 1 - System with swivel arms and rotating weights. In this system the weights are pushed ahead by connected with ball bearings arms and central cross rotor. The solution assumes of ex-center location of mass - longer distance from the center of mass on the top and shorter distance on the bottom of the device. The device should transform circular movement of the weights to linear motion. An external rim is collecting push force on the top more than on the bottom. System could work properly also if the weights would be pulled by rotor and swivel arms.

Type 2 - One rod inertial propulsion. System is consisting of only one moving element not counting hub with through hole for the rod and the shaft with rotor of the electric motor. 

Type 3 - Inertial propulsion with magnetic clutch.

Type 4 - Ex-center swing machine.

Type 5 - A simple inertial drive which is easy to do in home condition or in small workshop. The entire system is consisting of four steel balls, external ring, one cross pipe and electric motor. The main principle of operation of this system is that the balls have free space for extend outside cross pipe and they are rotating on asymmetric trajectory in vertical direction - ex- center location of cross pipe, so on the bottom they are hiding inside pipe and on the top position they are extending from them more so the centrifugal force is stronger on the top because the balls have more kinetic energy on the top as they are moving with greater velocity than on the bottom what is caused by less distance from the center of their rotation on the bottom than on the top. The balls have also enough space to rotate inside the cross pipe however some friction will be appearing in this system. This friction can be decreased using brass rings instead the bearings placed in each end of the pipe.

Extra massive inertial propulsion system.

This propulsion system that I noticed one time on Alfred Evert site back in 90' or slightly later was in fact only a 2D drawing with additional ball bearings on the top of each weight. As a latest version I will make an animation in blender of similar system with a little different constructional assumptions. The main change rely on the change of smal ball bearings on the top of each mass on big needle bearings inside the external rim. Previous version was similar to this scheme:

On above picture is shown several weights rotating on central rotor shaft with many rods, on each rod is moving one the weight. The picture is simplified. System has mechanical energy supply by external electric motor. The weights have linear bearings between rods and itself what is not shown on this picture. 

I've added also electric motor which is delivering the mechanical power to the system. Another big change is making the weights as a doubled masses connected by a rods to obtain more geometrical and functional stiffness to avoid uncontrolled rotation of the masses on round rods, making it double with connection allows to avoid this problem and increasing the weight mass at once two times. The quantity of rotating masses is eight. The system have also linear bearings inside each of rotating mass in number of 2 for each pair of weights. This propulsion have additionally rounded corners as a finish of the weights what allows for a better sliding of the weights on the needle bearings.   

It is recommended to apply some lead fill in the inside of the weights for make better parameters of acting forces, however it is not necessary because the weight of steel is enough for this solution. This system should to operate with a greater speed in comparison to the system with more ex-center placement of the point of rotation as is seen in previous scheme. I applied here less ex-center solution with more respect for greater speed of rotation and bigger rotating mass for less vibration reasons.

The system if right constructed could give a lot of power and should be able to lift heavy loads, crew and equipment. However the main obstacle in this case to obtain an efficient working prototype is the lack of financial support for starting crucial works on this technology. Rocket technology needs a dangerous fuel and liquid oxygen. What we got here is a propellant-less clean propulsion method capable of eliminate every jet and rocket transport and it is a simple inertial propulsion system as a many I was presented lately unfortunately having only a hope that someday this propulsion will see the daylight for good of all mankind.  

The main shaft is equipped with big ball bearings suspending the main rotor with masses. There can be second the same bearing for the support additionally the rotor from other another side. In the previous version from the autor Alfred Evert drawing the system was looking like this. This is two cut away through the rotor and external case. There are no bearings and no electric motor. Drawing is 2D plane picture.

If I will have more time and better mood for making more documentation of this impressive propulsion method I will make a animation what will show exactly how this device works.
