摘要:
Methods and apparatus for cooling a surface on a flight vehicle and generating power include advancing the vehicle at a speed of at least Mach 3 to aerodynamically heat the surface. A first working fluid circulates through a first fluid loop that heats the first working fluid through a heat intake thermally coupled to the surface and expands the first working fluid in a first thermal engine to generate a first work output. A second fluid loop has a second working fluid that receives heat from the first working fluid and a second thermal engine to generate a second work output. The first and second work outputs are operably coupled to first and second generators, respectively, to power primary or auxiliary systems on the flight vehicle.
摘要:
A plant for the production of energy that is based upon the organic Rankine cycle (ORC). The plant comprises a first ORC system, comprising a first organic operating fluid circulating, in sequence, between a first evaporator in conditions of heat exchange with a heat source, a first expansion stage in a turbine operatively connected to a generator, a first evaporator/condenser, and a first pump for recirculating said first organic operating fluid to said first evaporator. Said turbine is a partializable turbine and comprises means for partializing the incoming flowrate of said organic operating fluids, said means being designed to partialize said incoming flowrate to keep the r.p.m. of said turbine constant.
摘要:
A boiler unit comprises an enclosure including: a first circuit of a first fluid heat exchange medium, the first circuit having a heating device to heat the first medium, a boost heat exchanger, a valve and a first manifold; a second circuit of a second heating system fluid heat exchange medium, the second circuit having a flow and return port of the boiler unit, a second manifold and said boost heat exchanger for exchange of heat between said first and second heat exchanger media when said valve is open; a space in the enclosure receiving an auxiliary unit to be driven substantially exclusively by said first fluid heat exchange medium; and a boiler control unit to control operation of the heating device according to heat demand of the heating device and otherwise irrespective of the auxiliary unit when connected; and an organic rankine cycle (ORC) unit comprising: a third fluid heat exchange medium circuit, the circuit including a condenser adapted for connection to said second manifold to provide heat to said second circuit, a pump to circulate said third medium, an evaporator adapted for connection to said first manifold to heat said third medium and a rotary expander connected to an electricity generator; and an auxiliary control unit to control the ORC unit and operate said valve.
