HELICOPTER POWER AVAILABLE TO HOVER INDICATOR

Номер: CA1206261A
Принадлежит: CHANDLER EVANS INC, CHANDLER EVANS INC.

Helicopter Power Available To Hover Indicator The power required for a helicopter to hover is generated (14, 82) as the ratio of current operating power in forward flight (12, 77) determined (10, 73) from data relating operating power in forward flight to power required for hover for the aircraft. The power required to hover is compared (18, 83) with the maximum power available developed (16, Fig. 2; Fig. 3) by an engine model algorithm utilizing actual engine parameters. The comparison of maximum power to power required for hover is utilized to provide an indication (22) to the pilot. The viability of the indication is indicated by a "ready" indication (26).

PUMP ASSEMBLY INCORPORATING VANE PUMP AND IMPELLER PUMP

Номер: CA1080544A
Принадлежит: CHANDLER EVANS INC, CHANDLER EVANS INC.

ABSTRACT OF THE DISCLOSURE A fuel pump assembly for supplying fuel to a gas turbine engine has a centrifugal pump, including an imp-eller, that furnishes the necessary pressure for engine operation at high engine speeds. A vane pump, attached to the back side of the impeller of the centrifugal pump, supplies fuel to the engine for starting and acceleration to idle. The vane pump is of the type having a stationary centrally disposed cam and an annular rotor with radially inwardly directed vanes which ride over the surface of the cam. Before idle speed is attained, the vanes which are substantially hydraulically balanced and made of a light plastic material are adapted to lift off the surface of the cam without the need of pressure relief behind the vanes.

CLUTCH CONNECTED MULTI-STAGE IMPELLER PUMP

Номер: CA1073743A
Принадлежит: CHANDLER EVANS INC, CHANDLER EVANS INC.

A boost pump incorporates a low-flow impeller pump for charging the inlet of a gas producer fuel pump and a high-flow impeller pump for charging the inlet of an augmentor fuel pump. The low-flow pump is connected to a drive shaft so as to be continuously driven thereby. The drive shaft may be placed in driving connection with the high-flow pump through the medium of a friction clutch which is engageable by the application of a fluid pressure. Disengagement of the high-flow impeller, when augmentation is not required, significantly contributes to an increase in pump efficiency and a reduction in heating of the fluid being pumped.

FUEL CONTROL METHOD AND APPARATUS A fuel control for a gas turbine engine has a positive displacement pump (10) which directs fuel to a constant flow regulator (14) which generates a constant flow of fuel. A flow diverter (16) includes a dividing device which divides the constant flow of fuel between a discharge conduit (18) connected to the burner nozzles of the engine and a bypass conduit (20) connected to the inlet side of the pump. A computer (22) which is adapted to sense various engine parameters; and calculate fuel flow controls the flow dividing device in order to apportion the flow so that the calculated fuel flow is delivered to the engine.

ABSTRACT OF THE DISCLOSURE A fuel pump assembly for a gas turbine engine incorporates an impeller pump and a vane pump which are driven by a common drive shaft. A centrifugally operated clutch functions to disengage the vane pump from the drive shaft at a predetermined angular velocity. The vane pump is designed to fulfill dry lift, starting flow and pressure requirements for the engine. The impeller pump, alone, provides fuel to the engine near idle speed and above after the vane pump has been disengaged from the drive shaft.

PULSE WIDTH MODULATED FUEL METERING SYSTEM

Номер: CA1173160A
Принадлежит: CHANDLER EVANS INC, CHANDLER EVANS INC.

PULSE WITH MODULATED FUEL METERING SYSTEM ABSTRACT A fuel metering system for a gas turbine engine with a low pressure drop fuel vaporizing system includes an engine driven centrifugal pump (10) supplied with fuel at a given absolute pressure (Pi) from a tank The pump discharges fuel to a rapidly pulsed, solenoid operated ball valve (20) which functions as a metering valve in controlling flow to the engine. The solenoid (38) of the metering valve receives periodic voltage pulses of appropriate width from an electronic control which senses selected engine parameters and computes the required fuel flow and the pressure differential (Pr-PD) across the metering valve. Since the pressure differential across the metering valve increases with engine speed, favorable flow turndown ratios may be achieved without operating the metering valve at high or low values of duty cycle.

Gas turbine engine fuel metering system

Номер: US4004412A
Автор: Dennis G. A. Burnell
Принадлежит: Chandler Evans Inc

A fuel control system has a positive displacement gear pump for supplying a metered fuel flow to a gas turbine engine. A variable speed drive mechanism, as constituted by a hysteresis type of electro-magnetic clutch driven by the engine, is operatively connected to the pump for varying the speed of the pump in accordance with a commanded pump speed signal. A scheduling device, which senses various engine parameters, generates a signal indicative of a scheduled fuel flow. The fuel flow signal is, in turn, applied to a function generator which supplies the commanded pump speed signal in accordance with a predetermined relationship between pump speed and fuel flow for the engine sought to be controlled. The relationship between pump speed and fuel flow may be calculated for a wide range of flight conditions since the pressure rise or head across the pump is basically a function of fuel flow. This arrangement obviates the use of a head regulator for highly accurate fuel metering.

ABSTRACT OF THE DISCLOSURE A high pressure centrifugal pump has an impeller assembly including two mating impeller sections which are each constituted by a shroud with fixed geometry blades. The impeller sections are fixedly mounted upon a rotatable shaft and are of a con-struction which permits the pressure between the impeller section to engender flexure of the sections away from each other so as to vary the breadth of the impeller assembly. A servo control device is adapted to control the pressure behind the shrouds such that the pump delivers a constant flow at varying back pressures.

ABSTRACT OF THE DISCLOSURE An axial inducer, which charge the inlet of a centrifugal impeller has a bypass loop connecting its inlet and outlet. A valve member for controlling bypass flow is positioned in the bypass loop. At low flows, the bypass loop permits the inducer to run closer to design flow conditions than would otherwise be possible and, consequently, generate less pressure rise, consume minimum power, and cause minimal heating of the fluid being pumped. An extension of the bypass valve member functions to restrict the centrifugal pump discharge area when the valve member is positioned to bypass flow to reduce recirculating flow in the centrifugal impeller and increase its efficiency.

The elements have mutually engaging tongues and grooves, Figs.3 and 4 (not shown), and are prevented from rotating by a frame 30 and pistons 43, 45. An inlet conduit 16 communicates with a pair of inlet ports in each element, Figs.3 and 5 (not shown), by way of a cavity 14. A pair of outlet ports in each element is connected to a discharge conduit 14b by way of a passage 26f, or 28f, and the interior of a wash-flow filter 148. A pressureloaded piston 52 urges an end plate 48 and the rotor towards a further end plate 46. Each of the end plates has lugs 136, 138 engaging with holes in the frame 30 to prevent rotation. Pressure is communicated to the inner ends of the vanes from the passages 26f, 28f through apertures 122, 124 in register with said passages, and recesses 126, 128 in each end plate. Recesses 132, 134 facilitate escape of leakage fluid and limit the outward thrust on each plate. The profile of the cam track is described in detail with reference to Fig.1A (not shown). To actuate the pistons 34, 36 a pressure differential is applied through conduits 226, 228 to bellows 216 and thereby moves a value spool 188, 190, 192, 194 accordingly to apply inlet and discharge pressures to opposite sides of the pistons, the discharge pressure being transmitted through the filter.

[Classes 7 (iii) and 7 (vi)] [Also in Group XXVIII] A system for supplying fuel or antidetonant liquid to the cylinders of a multi-cylinder engine comprises a rotary distributing piston which is moved axially by liquid pressure to maintain the flow of liquid to the cylinders proportional to the air flow. In Fig. 1 fuel from a pump 32 is delivered to injectors located in the cylinders or adjacent the intake valves through pipes 59 controlled by a notch 56 in a rotary distributor piston 46 moved axially by the pressure differential across a metering orifice 80 to vary the area of the outlet orifices 58 uncovered by the slot 56. A pipe 60, similar to the pipes 59 leading to the injectors, supplies fuel to the metering orifice 80 and chamber 44, from which it flows through a pipe 90 to a valve 94 comprising a stem 28, actuated by a bellows 22 subjected to the air pressure differential at a Venturi 10 in the intake pipe 12, and a sliding sleeve 92 actuated by a bellows 84 subjected to the tuel pressure differential across the orifice 80, and then to a drain pipe 96. The valve 94 controls the pressure in chamber 44, and hence the position of piston 46, to maintain the flow through orifice 80, which is a measure of the flow through each pipe 59, proportional to the air flow.

A fuel metering system for a gas turbine engine with a low pressure drop fuel vaporizing system includes an engine driven centrifugal pump (10) supplied with fuel at a given absolute pressure (Pi) from a tank. The pump discharges fuel to a rapidly pulsed, solenoid operated ball valve (20) which functions as a metering valve in controlling flow to the engine. The solenoid (38) of the metering valve receives periodic voltage pulses of appropriate width from an electronic control which senses selected engine parameters and computes the required fuel flow and the pressure differential (Pr-P D ) across the metering valve. Since the pressure differential across the metering valve increases with engine speed, favorable flow turndown ratios may be achieved without operating the metering valve at high or low values of duty cycle.

Isolation of the operating region of the relays from the receivers is accomplished by bleeding off the boundary layer about the outlet passages to cause total discontinuity in the subsonic portion of the fluid stream. The disclosed relays are also characterized by absence of an abrupt change in section where the fluid enters the operating region.
