A deployable reflector antenna is provided. An example antenna includes a deployable ring including a plurality of internal combined arms, a plurality of external combined arms, and a plurality of joints arranged circumferentially in a predetermined number of tiers from a bottom of the deployable ring to a top of the deployable ring. Each of the plurality of joints connects, in a scissor linkage configuration, at least one internal arm and at least one external arm. The antenna includes torsion springs configured to bias the deployable ring towards an open position, with at least one of the torsion springs coupled to one or more of the joints. The antenna includes a plurality of tension, each connecting two joints positioned within the same tier. The antenna includes a flexible reflector mounted on the deployable ring. The flexible reflector includes an upper concave mesh, a lower convex mesh, and connecting flexible rods.

Deployable symmetrical reflector antenna

Provided is a deployable reflector that includes a reflector, a tensioning frame with a deploying ring including upper booms and lower booms, sections composed of lower rods and upper rods and including pantograph levers, stanchions mounted between the upper booms and the lower booms, scissors-like levers located at an intersection of the pantograph levers, first sleeves put on the pantograph levers, second sleeves disposed on the lower rods and the upper rods, cylindrical joints disposed on the second sleeves, an expansion ring for connecting the upper rods and the lower rods, a reflector fixing mesh having triangular cells composed of elastic rods, an upper concave mesh and a lower convex mesh fastened with peripheral units and composed of triangular shape cells, where the reflector is attached to the upper concave mesh directly or is fastened to the upper concave mesh with a spatial shape gasket.

Deployable reflector

An integrated nozzle set for injecting a substance into a turbine is provided. The nozzle set includes an outer nozzle container arranged around a part of a circle and an inner nozzle container having a first part arranged around a remaining part of the circle and a second part concentric with the outer nozzle container. The nozzle set further includes a diaphragm connected to the inner nozzle container and configured to seal a cavity of the turbine, a flange having spokes connected to the inner nozzle container, a set of nozzles, and collectors inserted into the outer nozzle container and configured to collect a substance. The nozzles include a first group of nozzles disposed in the outer nozzle container, a second group of nozzles disposed in the first part of the inner nozzle container, and a third group of nozzles disposed in the second part of the inner nozzle container.
