Air compressed inside a balloon exerts force upon the confine of the balloon. The air has mass and the mass of the air is proportional to its density, and density is proportional to temperature and pressure. Air molecules are driven farther apart as temperature increases. The air mass confined inside the balloon accelerate from the balloon, creating a force when it is released. This force increases as mass and acceleration increase as stated in Newton’s Second Law (F=MA).The force created by the acceleration of the air mass inside the balloon results in an equal and opposite force that causes the balloon to be propelled in the opposite direction, as stated in the Newton’s Third Law; “every action produces an equal and opposite reaction.
Replacing the air inside the balloon sustains the force and allows a load to be driven by the flow of the air mass accelerating across and driving a turbine. Replacing the balloon with a turbine, fuel is injected between the compressor and the turbine to further accelerate the air mass, thus, multiplying the force used to drive the load.
