Abstract: A Rankine cycle apparatus (1A) of the present disclosure includes a main circuit (10), a heat exchange portion (HX), a bypass flow path (20), a flow rate-adjusting mechanism (3), and a pair of temperature sensors (7A). The main circuit (10) is formed by an expander (11), a condenser (13), a pump (14), and an evaporator (15) that are circularly connected in this order. The heat exchange portion (HX) is located in the main circuit (10) at a position between an outlet of the expander (11) and an inlet of the pump (14). The bypass flow path (20) branches from the main circuit (10) at a position between an outlet of the evaporator (15) and an inlet of the expander (11), and joins to the main circuit (10) at a position between the outlet of the expander (11) and an inlet of the heat exchange portion (HX). The flow rate-adjusting mechanism (3) adjusts the flow rate of the working fluid in the bypass flow path (20).

Abstract: A steam turbine system including a steam turbine is provided. The steam turbine system includes a high-pressure side steam inlet device, a low-pressure side steam device, and a control device for controlling the steam turbine. An additional steam inlet device is also included arranged between the high-pressure side steam inlet device and the low-pressure side steam device. The control device control a supply of steam via the additional steam inlet device as a function of operating parameters detected at the steam turbine system.

Abstract: An air cycle machine (10) has a first stage turbine (60) mounted to a central portion of a common shaft (12), a compressor (50) mounted to the central portion of the shaft (12), a second stage turbine (30) mounted to a first end of the shaft (12), and a fan (40) mounted to a second end of the shaft (12), all for rotation therewith about a longitudinal axis (14). The first and second stage turbines (60, 30) are operative to extract energy from a flow of compressed air for driving the shaft (12), and the fan (40) and the compressor (50), in rotation about the axis (14).

Abstract: An arrangement for influencing a cooling air flow passing through a cooling air system of an internal-combustion engine of a vehicle includes a heat exchanger and a blower arranged in an air guiding housing, a cooling air outlet opening being arranged in the air guiding housing between the blower and a wall of an internal-combustion engine capsule in the area of the bottom side of the vehicle. In order to achieve a better efficiency of the blower and in order to prevent the emission of sounds from the ventilated capsule, pivotable guide blades are arranged in flow direction in front of and/or behind the running blades of the blower which, as a function of thir position, closes the cooling air inlet opening to the capsule and opens the cooling air outlet opening arranged in the air guiding space between the heat exchanger and the blower.

Abstract: Temperature regulation of an air cycle refrigeration system is achieved by selectively adjusting the turbine stator geometry in response to the temperature of turbine airflow at a desired location. Such adjustment in stator geometry includes the selective positioning of a portion of the stator adjacent the turbine blades thereby controlling the amount of cooling produced by the turbine or the selective opening and closing of bypass ports provided in the turbine stator to control the flow of air through the turbine. Both of these adjustments in stator geometry are effected by an actuator comprising at least two members of differing coefficients of thermal expansion such as a bimetallic element.

Abstract: A linkage system for actuating the variable vanes and the air bleed valve of a gas turbine engine compressor in an intermittent sequence includes a single actuator and a linkage mechanism. The latter is formed of a first actuating linkage extending to the bleed control valve, a second actuation linkage extending to the variable guide vanes, and an intermediate crank mechanism connected to the first and second actuating linkages and also to the single actuator. The linkage system is operative to convert the linear motion from the single actuator to multiplane intermittent rotational motion of the actuating linkages extending to the variable vanes and the bleed valve of the compressor. When embodied in a military aircraft, the single actuator is preferably disposed above the compressor casing so as to make it less vulnerable to enemy ground fire.

Abstract: A control apparatus comprises a primary control unit composed of wicket gates of a hydraulic turbine and a secondary control unit composed of a bypass valve which is operated to open or close in cooperation with the opening or closing of the wicket gates. First and second link mechanisms are provided between the wicket gates and a hydraulic pressure distributor valve which is operatively connected to the bypass valve to control opening or closing of the latter. The first link mechanism detects the opening or closing motion of the wicket gates and transmits the corresponding signal to the hydraulic pressure distributor valve for the bypass valve, while the second link mechanism detect position of a pressure distributor valve plunger for the wicket gates and transmits the corresponding signal to the distributor valve for the bypass valve.

Abstract: A method for starting a blower in the form of a single-stage radial fan installed in a pressure system such as the circulating cooling system of a turbogenerator in which the resistance of the pressure system is varying during the starting operation by means of a starting duct provided with a throttling element. The throttling element is closed at any desired blower speed ranging from 10 to 100% of its rated speed when the point of intersection between the pressure system characteristic, modified on the basis of the open throttling element, and the blower characteristic has been reached whereupon the desired point of operation conforming to the blower characteristic and the system characteristic will regulate itself automatically.
