Description

Известные воздушные винты измен емого шага с гидравлической системой управлени , включающей в себ  центральный шток и поршень, управл ющий лопаст ми, а также р д сложных защитных устройств, ненадежны в эксплуатации ввиду возможности самоцроизвольиого перехода винта в сторону уменьшени  шага лопастей и создани  отрицательной т ги.Known propellers of variable pitch with a hydraulic control system, including a central rod and a piston controlling the blades, as well as a number of sophisticated protective devices, are unreliable in operation due to the possibility of self-moving of the propeller to reduce the blade pitch and create negative thrust .

Описываемый воздушный винт устран ет эти недостатки.The described propeller eliminates these disadvantages.

Сущность изобретени  заключаетс  в том, что винт оборудован с след щим упором односторонней фиксации шага в виде смонтированной на центральном штоке передвижной втулки с отверстием, взаимодействующим с каналом поршн  гидравлической системы управлени .The essence of the invention is that the screw is equipped with the following emphasis of one-sided fixation of the pitch in the form of a movable sleeve mounted on the central rod with a hole interacting with the piston channel of the hydraulic control system.

На чертеже схематически изображен воздушный винт измен емого шага с односторонней фиксацией шага,в разрезе.The drawing shows schematically the propeller of a variable pitch with one-sided fixation of the pitch, in section.

Поршень 1, воздушного винта измен емого шага пр мой схемы, перемеща сь на центральном штоке .2 и в цилиндрической части втулки 3 винта, раздел ет внутренний объем втулки на две нолости 4 и 5. Полость 4 малого, шага через канал 6 в поршне / и отверстие 7 в передвижной втулке 8 след щего упора соедин етс  с каналом 9 подвода масла от регул тора оборотов (на чертеже не показан). Полость 10 втулки след щего упора сообщаетс  через канал // при помощи не показанного на чертеже управл емого из кабины летательного аппарата электромагнитного клапана с каналом подачи масла.The piston 1 of the variable pitch propeller of the straight pattern, moving on the central rod .2 and in the cylindrical part of the screw hub 3, divides the internal volume of the sleeve into two sections 4 and 5. The cavity 4 is small, through the channel 6 in the piston / and the opening 7 in the movable sleeve 8 of the follow abutment is connected to the oil supply port 9 from the speed adjuster (not shown). The cavity 10 of the sleeve of the follower abutment is communicated through the channel // by means of a solenoid valve controlled from the cabin of an aircraft, not shown in the drawing, with an oil supply channel.

При увеличении установочного угла лопастей поршень /, упира сь в правый торец втулки 8, вместе с ней перемещаетс  влево, перекрыва  между собой каналы 6 и 9, при этом масло из полости 4 сливаетс  через канал 2.When increasing the installation angle of the blades, the piston /, resting against the right end of the sleeve 8, moves with it to the left, closing the channels 6 and 9 between them, and the oil from the cavity 4 is drained through the channel 2.

При уменьщении шага лопастей поршень / перемещаетс  в правую сторону, при этом втулка 8, остава сь на месте, соедин ет между собой через .отверстие 7 каналы 6 и 5, вследствие чего давление масла в поWhen the blade pitch is reduced, the piston / moves to the right side, while the sleeve 8, remaining in place, connects through each of the hole 7 channels 6 and 5, as a result of which the oil pressure in
