Power device based on alkali-water reaction

A power device based on alkali-water reaction, comprising:

• a reaction chamber configured to carry out a chemical reaction between water and an alkali element,
• an exhaust nozzle configured to exhaust the chemical reaction products generated in the reaction chamber,
• a siphon tube inside the reaction chamber, connected to the exhaust nozzle,
• a nozzle shutter plate sealing the exhaust nozzle and configured to be broken at a predetermined pressure, and
• an external pressure inlet configured to transmit pressure to the interior of the reaction chamber,
• a water reservoir configured to store water, and transfer the water to the reaction chamber,
• an alkali reservoir configured to store an alkali element, and transfer the alkali element to the reaction chamber, and
• transfer means connecting the reaction chamber to both reservoirs and configured to transmit pressure generated in the reaction chamber to the reservoirs, providing the transfer of the water and the alkali element from both reservoirs to the reaction chamber,
• wherein
• the reaction chamber is concentrically placed inside a cylindrical inner cavity of a rocket, having the reaction chamber a top base,
• the water reservoir and the alkali reservoir are separated by at least a vertical separation wall, and placed inside the cylindrical inner cavity, at the same height, and separated from the reaction chamber by means of the top base,
• the transfer means comprises
• a first injector placed on the top base of the reaction chamber connecting the water reservoir to the reaction chamber and configured to transfer the water from the water reservoir to the reaction chamber,
• a second injector placed on the top base of the reaction chamber connecting the alkali reservoir to the reaction chamber and configured to transfer the alkali element from the alkali reservoir to the reaction chamber,
• a variable cylindrical cavity placed over the reaction chamber, including both reservoirs, the variable cylindrical cavity comprising in turn
• a central piston forming the upper base,
• a mobile lateral wall joined to the central piston,
• a variable pressurization cavity placed over the variable cylindrical cavity and separated from said variable cylindrical cavity by means of the central piston, wherein a siphon portion of the siphon tube is located in the variable pressurization cavity and is connected to the exhaust nozzle, and wherein the external pressure inlet is placed in the variable pressurization cavity,
• orifices placed in the portion of the siphon tube located in the variable pressurization cavity, configured to transmit the pressure generated in the reaction chamber to the variable pressurization cavity,
• and in that the central piston is configured to be displaced by means of the pressure transmitted by the reaction chamber to the variable pressurization cavity, transferring both water and alkali element to the reaction chamber through the first and second injectors.
