摘要： Excessive swing of the feedwater (31) in power supply apparatus on the occurrence of a transient is suppressed by injecting an anticipatory compensating signal (ΔW fw ) into the control for the feedwater. Typical overshoot occurs on removal of a large part of the load, the steam flow is reduced so that the conventional control system reduces the flow of feedwater. At the same time there is a reduction of feedwater level in the steam generator (13.15) because of the collapse of the bubbles (125) under increased steam pressure. By the time the control responds to the drop in level, the apparatus has begun to stabilize so that there is overshoot. The anticipatory signal is derived from the boiling power (BP) which is a function of the nuclear power (2N) developed, the enthalpy of saturated water (h . ) and the enthalpy of the feedwater injected into the steam generator (h fw ). From the boiling power (BP) and the increment in steam pressure resulting from the transient an anticipatory increment of feedwater flow is derived. Thus increment is added to the other parameters controlling the feedwater.

摘要： The present invention relates generally to flow regulation in aircraft systems. More particularly, the present invention relates to a flow regulator 100 and a high-lift system 200 for an aircraft incorporating such a flow regulator 100. The flow regulator 100 comprises a fluid input port 102 for receiving a pressurized fluid, a fluid output port 104 for providing fluid having a regulated flow rate, and a regulator valve 106 connected in fluid communication between the fluid input port 102 and the fluid output port 104. The regulator valve 106 is operable to provide regulated fluid at a substantially constant output flow rate to the fluid output port 104. The flow regulator 100 also includes a flow switching mechanism 108 for switching the substantially constant output flow of the flow regulated fluid provided by the regulator valve 106 between a first flow rate and a second flow rate, the first flow rate being less than the second flow rate.

摘要： An apparatus (4) for controlling the flow of gas (2) into a container (3) comprises: a primary gas conduit (6) configured to feed inert gas from an inert gas source (2) at a pressure greater than atmospheric pressure to a container configured to receive flammable material; a first gas flow regulating means (8) operably connected to the primary gas conduit (6), and configured to regulate the flow of gas flowing therethrough; a secondary gas conduit (10) in fluid communication with the primary gas conduit, and disposed upstream of the first gas flow regulating means (8); gas storage means (20) operably connected to the secondary gas conduit (10), and configured to store a volume of inert gas; and a first valve (14) operably connected to the primary (6) or secondary (10) gas conduit, and disposed upstream of the gas storage means (20). The apparatus (3) is characterised in that it is configured to switch between a standby mode in which the storage means (20) is not in fluid communication with the inert gas source (2), and an activated mode in which the storage means (20) is in fluid communication with the inert gas source (2), and wherein the first flow regulating means (8) is configured to prevent the pressure of the inert gas downstream of the first flow regulating means (8) from exceeding the pressure of the inert gas in the storage means (20).
