专利汇可以提供Turbine engine control system专利检索,专利查询,专利分析的服务。并且A turbine engine control system, including a fuel control is provided with a fuel inlet, a fuel metering valve assembly responsive to electrical signals generated in response to engine speed and temperature and indicia of operator power request, a fuel bypass valving means for returning unmetered fuel from the area of the fuel metering valve assembly to an area of low pressure fuel, a compressor discharge pressure sensing means tending to further close the bypass valving means as compressor discharge pressure increases, and a pressure responsive means responsive to the differential in pressures which meters the fuel for opening said bypass valving means in order to achieve a rate of metered fuel flow corresponding to compressor discharge pressure; a variable nozzle assembly within an associated turbine engine is variably opened and closed by related control sections responsive at least in part to engine operating parameters.,下面是Turbine engine control system专利的具体信息内容。

1. A control system for a turbine engine having a gasifier section, a power output turbine and a variably openable nozzle assembly generally interposed between said gasifier section and said power turbine effective to at least at times variably restrict the flow to said power turbine of gases generated in said gasifier section, comprising fluid operating actuating means operatively connected to said variable nozzle assembly and effective to actuate said nozzle assembly to varying degrees of opening, servo valve means situated generally between a source of pressurized actuating fluid and said actuating means for controlling the flow of said actuating fluid to said actuating means, electrical control means including an electrical control circuit effective to vary the position of said servo valve means, additional means responsive to indicia operation of said turbine engine and the degree of opening of said nozzle assembly for in turn creating and applying a an electrical control signal to said electrical control means in order to thereby affect a desired movement of said servo valve means, and electrical feedback means responsive to the degree of opening of said variable nozzle means for operatively creating a feedback signal to said control means indicative of the then existing degree of opening of said variable nozzle means.
