Abstract
.Использование: демонстрационные установки и может быть использовано на лекци х по курсу общей физики. Сущность изобретени : устройство содержит газодинамическую скамью, размещенное на ней рабочее тело, снабженное Г-образной трубкой . В рабочем теле выполнено сквозное отверстие, в котором размещена входна часть трубки. Трубка выполнена с регулируемыми и фиксируемыми параметрами, Реактивное движение осуществл етс за счет потока газа из трубки. 2 з.п. ф-лы, 2 ил..Usage: Demonstration facilities and can be used in lectures on the course of general physics. SUMMARY OF THE INVENTION: the device comprises a gas-dynamic bench, a working fluid placed on it, provided with an L-shaped tube. A through hole is made in the working fluid in which the inlet part of the tube is located. The tube is made with adjustable and fixed parameters. The jet movement is carried out due to the flow of gas from the tube. 2 s.p. f-ly, 2 ill.
Description
Изобретение относитс к физическим демонстрационным установкам и может рыть использовано в процессе преподавани курса общей физики.The invention relates to physical demonstration facilities and can be used while teaching a course in general physics.
Цель изобретени - улучшение демонстрационных возможностей устройства.The purpose of the invention is to improve the demonstration capabilities of the device.
На фиг. 1 представлен вертикальный разрез устройства; на фиг. 2 - разрез А-А на фиг. 1.In FIG. 1 shows a vertical section through a device; in FIG. 2 is a section AA in FIG. 1.
Устройство дл демонстрации реактив- (ного движени содержит газодинамическую {жамъю 1 с перфорированными отверсти - Ми 2, рабочее тело 3, размещенное на Ькамье, в котором выполнено отверстие 4. В Отверстие 4 вставлена Г-образна трубка 5, Котора выполн етс из материала, позвол ющего измен ть геометрию трубки - измен ть угол отвода проход щего через нее аза. Напротив выходного отверсти труб- Ы размещен экран 6, закрепленный на щарнире 7 с возможностью поворота и фиксации.A device for demonstrating reactive motion comprises a gas-dynamic jam 1 with perforated holes Mi 2, a working fluid 3 placed on the bam, in which a hole 4 is made. A hole L-shaped tube 5 is inserted into the hole 4, which is made of material, allowing you to change the geometry of the tube - to change the angle of the outlet of the aza passing through it.
Устройство дл демонстрации реактивного движени работает следующим обратом . Через отверсти 2 подаетс газ. A device for demonstrating jet propulsion operates as follows. Gas is supplied through the openings 2.
приподнимающий рабочее тело 3 и позвол ющий телу перемещатьс по скамье 1 без трени . Часть газа подаетс через отверстие 4 и трубку 5 и отводитс в окружающее пространство (слева на чертеже), вследствие чего тело 3 движетс вправо под действием реактивной силы. При наличии экрана 6 тело 3 движетс влево. Измен геометрические параметры экрана (угол наклона) и трубки 5, измен ет скорость (а в начальный период демонстрации при достаточной длине скамьи 1 - и ускорение) тела 3, варьиру параметры реактивного движени . По этим причинам демонстрационные возможности устройства улучшаютс .lifting the working medium 3 and allowing the body to move along the bench 1 without friction. Part of the gas is supplied through the hole 4 and the tube 5 and is discharged into the surrounding space (left in the drawing), as a result of which the body 3 moves to the right under the influence of a reactive force. With screen 6, body 3 moves to the left. Changing the geometric parameters of the screen (angle of inclination) and the tube 5, changes the speed (and in the initial period of the demonstration with a sufficient length of the bench 1 - and the acceleration) of the body 3, varying the parameters of the jet movement. For these reasons, the demonstration capabilities of the device are improved.
