Description

Предлагаютс  аэродинамические весы дл  измерени  лобового сопротивлени  моделей, позвол ющие производить измерени  малых значений лобового сопротивлени  путем выполнени  державки, несущей модель , в виде ма тника, опора которого вынесена за пределы трубы.An aerodynamic balance is offered for measuring the drag of models, allowing measurements of small values of drag by making a holder carrying the model in the form of a tambourine, the support of which is moved outside the pipe.

Схема устройства показана на чертеже.Diagram of the device shown in the drawing.

Испытываема  модель 1 укрепл етс  в аэродинамической или газодинамической трубе 2 на державке 3, укрепл емой наверху трубы вне потока. Нижн   часть также выведена нз трубы и несет на конце диафрагму 4. Та часть державки, котора  находитс  в потоке, закрыта обтекателем 5. Державка несет на себе посто нный магнит 6, помещенный в магнитном поле катушки 7, управл емом фотоэлектрическим устройством. Устройство выполнено в виде двух диафрагм, одна (4) из которых св зана с державкой модели, а втора  (8) неподвижна. По разные стороны диафрагм располагаютс  источник света 9, конденсор 10 и фотоэлемент П.The test model 1 is mounted in a wind tunnel or gas dynamic tube 2 on the holder 3, which is fixed at the top of the pipe out of flow. The lower part is also removed from the pipe and carries a diaphragm 4 at the end. The part of the holder that is in the flow is covered by the fairing 5. The holder carries a permanent magnet 6 placed in the magnetic field of the coil 7 controlled by a photoelectric device. The device is made in the form of two diaphragms, one (4) of which is connected with the model holder and the second (8) is fixed. A light source 9, a condenser 10 and a photocell P. are located on opposite sides of the diaphragms.

При действии усили  на испытываемую модель державка 3, представл юща  собой ма тник, отклон етс , и диафрагмы 4 н 8 перемещаютс  одна относительно другой. При этом измен етс  количество света, падающего на фотоэлемент 11, и соответственно величина усиленного тока в катущке 7. Это приводит к изменению магнитного пол , воздействующего с полем посто нного магнита, и вызывает уравновещивание ма тника-державки.Under the effect of the force on the model under test, the holder 3, which is a thumb, deviates, and the diaphragms 4 and 8 move one relative to the other. This changes the amount of light incident on the photocell 11, and accordingly, the magnitude of the amplified current in the coil 7. This leads to a change in the magnetic field acting on the permanent magnet field and causes equilibration of the magnetic holder.

Предмет изобретени Subject invention

Аэродинамические весы дл  измерени  лобового сопротивлени  моделей , в которых державка, несуща  модель и помещенна  в потоке, закрыта обтекателем, а дл  уравновещивани  измер емой силы примененAn aerodynamic balance for measuring the drag of models in which the holder holding the model and placed in the flow is closed by a fairing, and for balancing the measured force

посто нный магнит, св занный с державкой и помещенный в магнитном поле катушки, управл емом фотоэлектрическим устройством, представл ющим собой подвижную, св занную с державкой, и неподвил ную диафрагмы , по разные стороны которых располагаетс  источник света и фотоэлемент, отличающиес  тем, что, е цел-ью измерени  малых значений лобового сопротивлени , державка выполнена в виде ма тника, олора которого вынесена за пределы трубы.a permanent magnet associated with a holder and placed in a magnetic field of a coil controlled by a photovoltaic device, which is a mobile, associated with the holder, and non-adjustable diaphragms, on either side of which there is a light source and a photocell, characterized in that For the purpose of measuring small values of drag, the holder is made in the form of an emblem, the hole of which is placed outside the pipe.
