Method of driving a turbine in rotation by means of a jet device

A method of driving a turbine that is disposed between an admission channel and an ejection channel, said method comprising:

• generating a flow of a secondary fluid having a secondary mass flow into said admission channel at a secondary velocity;
• injecting a primary fluid having a primary mass flow into said admission channel at a primary velocity, said primary velocity being greater than said secondary velocity, said injecting step occurring substantially simultaneously with said generating step so as to create within said admission channel a mixture of said primary fluid and said secondary fluid, said mixture having a mass flow substantially equal to a sum of said primary mass flow and said secondary mass flow and a velocity toward said turbine that is less than said primary velocity;
• passing said mixture through blades of said turbine;
• substantially adapting a pressure of said mixture to an ambient pressure outside of said ejection channel;
• and
• ejecting said mixture via said ejection channel, wherein a velocity of said primary fluid is supersonic before said primary fluid is injected into said admission channel.

A turbine device comprising:

• a body having a symmetry of revolution and comprising an admission channel and an ejection channel;
• a turbine disposed between said admission channel and said ejection channel;
• injection means for injecting a primary fluid having a primary mass flow into said admission channel at a primary velocity;
• inlet means for generating a flow of a secondary fluid having a secondary a mass flow into said admission channel at a secondary velocity, said secondary velocity being less than said primary velocity, said inlet means being disposed relative to said injection means such that a mixture of said primary fluid and said secondary fluid is formed in said admission channel, said mixture having a mass flow substantially equal to a sum of said primary mass flow and said secondary mass flow and a velocity toward said turbine that is less than said primary velocity;
• and
• means disposed within said election channel for receiving said mixture of said primary and said secondary fluids from said turbine at a given pressure and substantially adapting said given pressure to an ambient pressure outside of said body in a vicinity of said outlet means.
