Planetary gear-sets can be incorporated in the design of an IC engine by replacing the conventional style crankshaft. This concept could be used in IC engines of all sizes, two or four stroke, gas or diesel, the only stipulation being, in its simplest form,
Background: During the disputes that cost many countries lives due to the terrorists and extremists, the members of national defense seek to secure data transmission between their members.
The recent way of communication can be hacked due to the common way may easily recognized by them ,
An IEDD or Impact Energy Dissipater Device meant for the prevention of fatal injury from impact related incidents of high-speed vehicles and the like.
The presented idea is a full mechanical, magnetic and electrical design of an in-wheel brushless DC outer rotor (hub) motor. The rim of any wheel would serve as the rotor, after some modifications, for the motor. Varying rims sizes yields varying power throughput.
Synopsis:
Only about 30% of the fuel energy changes to useful work in Internal Combustion Engines (ICE`s). The exhaust exergy of the engine has approximately the same amount as the output work.
The thrust of a solid propellant rocket depends directly upon the burning surface area of the solid grain. Therefore we try to modify the shape of the solid propellant grain to get the maximum surface area.
Problem Statement:
Production demands on skilled workers are at an all time high. Welders, assembly technicians, machine builders and repair workers all have to endure long hours of repetitive physical maneuvers which many times include hand cranking workbench clamps and vises.
Individual drug tester of the cleanness of the chemical surface of fruit and vegetables.
