Abstract

FIELD: parachutes.
SUBSTANCE: parachute consists of a dome, main lines and a damper in the form of two cylinders, which join each other, filled with oil, with the possibility of flowing into the expander under the influence of resistance of the etched line, with the desired opening time of the dome.
EFFECT: invention is aimed at reducing the impact when the canopy is opened.

Description

Известны применяемые в настоящее время парашюты для опускания с высоты людей и, например, при десантировании вооружений.Known currently used parachutes for lowering people from a height and, for example, when landing weapons.

Недостатком таких парашютов являются значительные:The disadvantage of such parachutes are significant:

а) рывки при раскрытии иa) jerks during disclosure and

б) значительные снижения для больших парашютов в центре купола отверстия, уменьшающего эффективность парашюта.b) significant reductions for large parachutes in the center of the dome of the hole, reducing the effectiveness of the parachute.

С целью снижения рывков предлагается парашют снабдить демпферным устройством, изображенным на чертеже.In order to reduce jerking, it is proposed to provide the parachute with a damper device shown in the drawing.

Парашют основных строп состоит из основных строп 1 купола 2, вывернутого наизнанку, к вершине которого привязана стропа травления 3, внизу навита на блоки полиспаста. Блоки полиспаста установлены на поверхностях двух цилиндров 4, входящих один в другой, заполненных жидким маслом 5. При сжатии полиспаста масло под давлением через отверстие 6 перекачивается в расширитель 7. На отверстии установлен регулирующий винт 8 диаметром более отверстия, увеличивающим или уменьшающим отверстие перетока масла. Этим достигается требуемое для раскрытия купола парашюта время.The parachute of the main lines consists of the main lines 1 of the dome 2, turned inside out, to the top of which the etching line 3 is attached, the bottom is wound onto the chain blocks. The tackle blocks are mounted on the surfaces of two cylinders 4, one in the other, filled with liquid oil 5. When the tackle is compressed, oil under pressure is pumped through the hole 6 into the expander 7. An adjustment screw 8 is installed on the hole 8 with a diameter larger than the hole, increasing or decreasing the oil flow hole. This achieves the time required for opening the canopy.

При положении А вывернутого купола из-за малой величины сопротивления потребуются значительное время. Поэтому практически можно установить желаемое время начало раскрытия купола в моменты А, В, С и т.д. Из СМИ известно, что военная техника десантируется при опускании со скоростью 25 м/сек, по-видимому, с целью исключения поражения. Предлагаемым парашютом можно увеличить скорость опускания, снабдив полиспаст реле времени, через которое требуется раскрыть парашют полностью вблизи земли, но только сбрасывать технику с заранее рассчитанной определенной высоты.With position A of the inverted dome, a considerable amount of time will be required due to the small resistance value. Therefore, it is practically possible to set the desired time for the opening of the dome at moments A, B, C, etc. It is known from the media that military equipment is landing when lowered at a speed of 25 m / s, apparently in order to exclude defeat. The proposed parachute can increase the lowering speed by equipping the tackle with a time relay, after which it is necessary to open the parachute completely near the ground, but only reset the equipment from a predetermined certain height.

Claims (1)

Парашют, отличающийся тем, что с целью уменьшения толчка при раскрытии купола он снабжен демпфером в виде двух цилиндров, входящих друг в друга, заполненных маслом с возможностью перетока в расширитель под воздействием сопротивления передаваемого стропой травления с желаемым временем раскрытия купола.Parachute, characterized in that in order to reduce the shock during the opening of the dome, it is equipped with a damper in the form of two cylinders falling into each other, filled with oil with the possibility of overflow into the expander under the influence of the resistance transmitted by the pickling line with the desired opening time of the dome.
