Title: Innovations of Howard Purdum in Turbine Technology

Introduction

Howard Purdum is a notable inventor based in Research Triangle Park, NC (US). He has made significant contributions to turbine technology, holding 3 patents that showcase his innovative approach to energy efficiency and design.

Latest Patents

Purdum's latest patents include a reaction turbine operating on condensing vapors. This turbine utilizes the heat released from steam condensation, combined with inherent steam pressure and temperature heads. A series of rotors with multiple curved internal channels provide compressive boosts between successive stages while avoiding excessive self-compression. The design generates high levels of condensation, releasing immense amounts of heat. The resulting hot vapor and condensate droplets are ejected tangentially at the periphery of the rotors to generate thrust. The exhaust steam from the last stage is compressed and returned to the engine inlet, efficiently completing the system cycle without the need for large cooling towers.

Another patent is for a hybrid impulse reaction turbine. This turbine features channels formed in the top surface of a disc to create nozzles. The channels can be covered by a membrane sealed to the disc or by housing extended from a combustor. Each channel has a first section extending radially outwardly from the inlet and a second curved section extending to the periphery of the disc. The reaction turbine may also receive input from an impulse turbine, with fluid flowing through the impulse turbine entering the reaction turbine's inlet. Additionally, the design includes cooling channels and fins to lower the disc's temperature during operation, and magnets may provide bearing support and electricity generation.
