    摘要: A rotor hub fairing system includes an upper hub fairing, a lower hub fairing and a shaft fairing therebetween. The rotor hub fairing system is sized and configured to reduce the overall drag on a dual, counter-rotating, coaxial rotor system. Preferably, the rotor hub fairing is fully integrated. The shaft fairing preferably includes a minimal thickness at the midsection to reduce drag with an increasing thickness adjacent the upper and lower hub fairings to reduce the flow separation on the hub fairing surfaces without overly excessive drag. Other aerodynamic structures, such as a horizontal splitter and/or a plurality of turning vanes may be mounted to the shaft fairing to facilitate flow around the upper and lower hub fairings to reduce flow separation and drag.

    摘要: In a waste heat recovery system wherein an organic rankine cycle system uses waste heat from the fluids of a reciprocating engine, provision is made to continue operation of the engine even during periods when the organic rankine cycle system is inoperative, by providing an auxiliary pump and a bypass for the refrigerant flow around the turbine. Provision is also made to divert the engine exhaust gases from the evaporator during such periods of operation. In one embodiment, the auxiliary pump is made to operate simultaneously with the primary pump during normal operations, thereby allowing the primary pump to operate at lower speeds with less likelihood of cavitation.

    摘要: In a waste heat recovery system wherein a heat exchanger derives heat from an engine exhaust, a venturi is fluidly connected to an engine exhaust port so as to thereby increase the flow rate and reduce the pressure in a manifold which is fluidly connected between the venturis and the heat exchanger. A fan is provided downstream of the heat exchanger to draw hot gases from the manifold, through the heat exchanger and discharge it to ambient. But when the fan is not operating during periods in which the engine is operating, the lower pressure manifold will draw ambient air in through the fan and through the heat exchanger, with the ambient air then being entrained in the exhaust gases being discharged from an exhaust channel downstream of the venturi. In one embodiment, a plurality of heat sources are provided with each having its own venturi connected to the common low pressure manifold. One or more of the plurality of waste heat source may be nonoperative or operating at a lower speed, but because of the low pressure manifold, the hot gases from the operative/higher speed waste heat source will not flow to the nonoperative or slower running waste heat source. Check valves are provided to allow the discharge of hot gases to ambient from the exhaust channels but not allow the flow of ambient air into the exhaust channels. A bypass valve is provided to selectively allow for the flow of ambient air into the exhaust channel and into the manifold for purposes of dilution during periods in which the fan is in operation.
