Fluid-Driven Turbomachinery with Hollow Turbine Arms, Ducted Cone Receivers, and Reaction Nozzles

**Abstract**This disclosure presents a unified turbomachinery architecture employing a ducted cone fluid receiver and hollow turbine arms with internal flow channels terminating in tangential nozzles. The expelled fluid produces jet-reaction torque, driving a rotating hub and attached arms to deliver mechanical output or thrust. The system operates in both open-flow (wind or water) and closed-flow (combustion, exhaust, or steam) environments, offering a simplified, modular, and efficient alternative to conventional bladed turbines. Applications include renewable energy generation, turbocharging, steam power, microturbines, and hybrid aerospace propulsion. Representative Embodiments The disclosed turbomachinery system can be implemented in multiple configurations, including:(1) Wind or Water Turbine — hollow arms with adjustable nozzles for adaptive torque and energy capture;(2) Turbocharger — a low-inertia, exhaust-driven reaction turbine driving a compressor;(3) Steam Turbine — compact, simplified architecture suitable for combined heat and power (CHP) or geothermal plants;(4) Hub Turbine Jet System — modular hub assembly channeling gases to hollow arms for multi-mode operation;(5) Turbojet / Turbofan / Turboprop / Turboshaft — closed turbomachine configuration producing thrust and/or shaft power;(6) Advanced Free Turbine System — dual-stage layout featuring a one-way clutch coupling for differential speed control, enabling simultaneous production of thrust and mechanical torque; and(7) Extendable Turbine Arms — telescopic or variable-length arms that dynamically adjust radius to optimize torque and RPM during operation. All embodiments share the same core principle: fluid energy is directed through a ducted cone receiver and hollow arms terminating in tangential nozzles to produce jet-reaction torque. **Statement of Intent**This disclosure is made publicly and deliberately to establish prior art under U.S. patent law (35 U.S.C. §102) and international standards. The author holds a U.S. provisional patent application covering this invention and releases this summary to confirm public knowledge and block unauthorized patenting of equivalent or derivative systems.
