п тс  тензометрические весы. Затем на поршне 16 устанавливают фланец 20 и закрепл ют его гайками 18, 19 до упора в упор 17. После этого к фланцу 20 посредством установочных винтов 22 креп т тензометрические весы, а с помощью винтов 23- исследуемую модель. Устройство устанавливаетс  в рабочей части аэродинамической трубы. Перед запуском аэродинамической трубы в полость сильфона 15 от источника 11 газа iBHcoKoro давлени  подаетс  газ, и регистрируетс  давление в полости сильфона. Сильфон, деформиру сь, переда1ет нагрузку на упругие балки 3, 4, 5, нагружа  их силой, противоположной по направлению внешней гидродинамической нагрузке. Величина этой силы в зависимости от давлени  в полости модели устанавливаетс  путем предварительной тарировки. После этого запускают аэродинамическую трубу или ввод т устройство с исследуемой моделью в поток газа и регистрируют силы и моменты, действующие на модель . Таким образом, возможно в несколько раз уменьшить жесткость упругой части и сушественно повысить точность эксперимента . Формула изобретени  Устройство дл  измерени  сил и моментов , содержащее укрепленный на державке упругий элемент тензометрических весов, соединенный с поршнем, источник газа высокого давлени  с регул тором давлени  и преобразователь, отличающеес  тем, что, с целью повышени  точности измерени , в него введены сильфом, осевой патрубок , расположенный на державке, упор и фланец, укрепленный на поршне, причем в упругом элементе тензометрических весов выполнен осевой канал, в котором расположен СИЛЬФОН, с одной стороны жестко соединенный с осевым патрубком, а с другой-с поршнем, при этом в державке выполнен канал, соединенный с источником газа высокого давлени . Источники информации, прин тые во внимание при экспертизе 1.Авторское свидетельство СССР № 395561, кл. G OIL 1/22, 1959. PTS Strain Gauges. Then, the flange 20 is mounted on the piston 16 and secured with nuts 18, 19 until it stops against the stop 17. After that, the strain gauge is attached to the flange 20 by means of set screws 22, and the model under study is screwed using screws 23. The device is installed in the working part of the wind tunnel. Before launching the wind tunnel, gas is supplied to the cavity of the bellows 15 from the pressure source 11 of the iBHcoKoro gas, and the pressure in the cavity of the bellows is recorded. The bellows, deforming, transfers the load on the elastic beams 3, 4, 5, loading them with a force opposite to the external hydrodynamic load. The magnitude of this force, depending on the pressure in the cavity of the model, is established by preliminary calibration. After that, the wind tunnel is started or the device with the model under study is introduced into the gas flow and the forces and moments acting on the model are recorded. Thus, it is possible to reduce the stiffness of the elastic part several times and substantially increase the accuracy of the experiment. An apparatus for measuring forces and moments, comprising a resilient strain gage element fixed to a holder, connected to a piston, a high pressure gas source with a pressure regulator and a transducer, characterized in that, in order to improve measurement accuracy, an axial syringe is inserted into it. a branch pipe located on the holder, an emphasis and a flange mounted on the piston, and in the elastic element of the strain gauge there is an axial channel in which the BELLOWS is located, on one side rigidly connected to sevym pipe, and on the other to the piston, wherein the channel is formed in the holder, coupled to a source of high pressure gas.
