专利汇可以提供Fuel management system专利检索,专利查询,专利分析的服务。并且An aircraft fuel management system providing accurate and comparable measurement and display of on-board fuel quantity, fuel rate and flight time remaining. This system utilizes capacitance method of fuel gaging and fuel mass flow rate derived from both volumetric flow measurement and capacitance density compensation. These separate measurements - fuel gaging and mass flow rate - are combined electronically to obtain ''''flight time remaining'''' under prevailing flight conditions.,下面是Fuel management system专利的具体信息内容。

1. A system for measuring the flight time remaining for an aircraft having a fuel tank and at least one engine comprising: monitoring means located in the fuel tank and capacitatively responsive to the dielectric of the fuel so as to generate a signal responsive to the volume of the fuel; monitoring means located in the fuel tank and capacitatively responsive to the dielectric of the fuel in the tank to generate a signal responsive to the density of the fuel; monitoring means located in the fuel line upstream of the engine and capacitatively responsive to the dielectric of the fuel so that a signal is generated responsive to the density of the fuel; and monitoring means in the fuel line upstream of the engine and responsive to the flow of fuel therethrough so as to generate a signal indicative of the volume of fuel flowing through the flow line and coupled to said density monitor so as to generate a signal indicative of the mass flow rate of fuel through said flow line; and a bridging network combining the output signals of all of the monitoring means and coupled to an indicator to generate the flight time remaining indication.
2. The system claimed in claim 1 further including means coupling said fuel tank monitoring means to generate a signal indicative of the fuel mass in the tank, and further including means coupling said fuel line monitoring means to generate a signal indicative of the rate of fuel mass consumption by the engine.
