Description

The utility model "hydraulic reactive drive of the main (propeller) propellers" refers to transport engineering and is intended for use on vehicles, in particular helicopters. The proposed "hydraulic reactive drive rotor (propeller) propellers" provides an increase in the efficiency (efficiency) of the drive rotor.

A hydraulic drive of a vehicle is known, comprising an adjustable pump and a hydraulic motor interconnected by hydraulic lines and forming a closed loop, a make-up pump mounted on one shaft with an adjustable pump and connected to a closed loop through check valves, the output of the make-up pump is connected to the input of the adjustable pump, a cooler and a filter with the formation of a closed loop, and a hydraulic accumulator connected by a working cavity with a closed loop [1]. Italicized - features common with the subject of a utility model.

Its significant drawback is low efficiency, which is due to the lack of compensation of the reactive component of the rotor torque.

It is known as a centrifugal hydraulic actuator that is closer in technical essence to a utility model, including a hydroficated drive, its shaft is connected to the drive part, which is a turbine and a reaction chamber coaxially mounted and hydraulically connected in series, driven into rotation by a pressure fluid flow from a separate hydraulic system operating using a hydraulic motor from the hydraulic system of the vehicle [2]. Italicized - features common with the subject of a utility model.

Its significant drawback is low efficiency, which is due to the lack of compensation of the reactive component of the rotational moment of the rotors.

The objective of the utility model is to increase the efficiency of the rotor hydraulic drive.

The technical result is achieved by the fact that a reactor installed in the reaction chamber and connected to the rotors with the rotor shaft is introduced into the hydraulic actuator containing the vehicle’s hydraulic system, the drive part, the turbine and jet chambers, which is operated by means of a hydraulic motor from the vehicle’s hydraulic system, and the reaction chamber is hydraulically in series connected to the hydraulic fluid collector, and through the hollow shaft and to the reactor, nozzles, which are directed in the direction opposite to the direction of rotation of the shaft, are connected to jet chamber. Hydraulic fluid collector, hollow shaft, reactor and reaction chamber, form a closed hydraulic system.

The scheme of the "hydraulic jet drive rotor (propeller) propellers" is shown in figure 1.

"Hydraulic reactive drive rotor (propeller) propellers" includes a shaft 1, a reactor 2 with nozzles 3, a reaction chamber 4 and a collection of 5 hydraulic fluids. The shaft 1, passing through the reaction chamber 4, hollow part hydraulically connects the reactor 2 and the hydraulic fluid collector 5 mechanically in the axial and radial directions is fixed by thrust rolling bearings.

"Hydraulic jet drive rotor (propeller) propellers" works as follows.

The drive of the main (propeller) rotors is mechanically connected through the coupling to the drive part, the turbine and the hydraulic motor of the vehicle hydraulic system (not shown in FIG. 1). When a rotating turbine, through the coupling, the rotation is transmitted to the drive of the main (propeller) rotors ", while under the action of centrifugal forces the contents (fluid) of the reactor 2 through

the nozzle 3 is discharged into the reaction chamber 4, and under its own weight, the hydraulic fluid flows into the hydraulic fluid collector 5. The use of a hydraulic fluid as a working fluid provides a reduction in the diameter of the arrangement of the nozzles of the reactor, a decrease in the rate of expiration of the working fluid from the nozzles, a decrease in the overall dimensions of the reactor, and alignment of the reactor with the main rotors, when the working fluid cycle (hydrofluid) is closed without emission to the atmosphere. The hydraulic jet drive of the bearing (propeller) propellers provides, by increasing the drive shaft torque, increasing its efficiency by 3-5%.
