Description
Изобретение относитс к измерительной технике и может быть использовано дл измерени направлени ветра или воздушного потока относи- . тельно некоторого тела в этом потоке .The invention relates to a measurement technique and can be used to measure the direction of the wind or the air flow. some body in this stream.
06 основному авт. св. № 802878 известен измеритель направлени воздушного потока, имекхций пробник, наход щийс в потоке и выполненный в виде разомкнутого аэродинамического профил со щелевыми отйерсти ми в местах сопр жени с цилиндрической частью пробника дл отбора давлени набегающего потока и с отверстием в хвостовой части и имеющий пневмодвигатель , размещенный на одном валу с пробником и выполненный в виде лопасти, аэродинамический момент которой со-впадает с моментом пробника 1.06 main author. St. No. 802878 is well known for measuring the direction of the air flow, an inlet probe located in the flow and made in the form of an open aerodynamic profile with slotted openings in conjugation with the cylindrical part of the probe for extracting the flow and with a hole in the tail section and having an air motor placed on the same shaft with the probe and made in the form of a blade, the aerodynamic moment of which coincides with the moment of probe 1.
Однакр известный измеритель обладает недостаточно высокой точностью измерени при малых углах скоса потока вследствие возникновени автоколебаний аэродинамическсгго профил пробника .However, the known meter has an insufficiently high accuracy of measurement at small bevel angles due to the occurrence of self-oscillations of the aerodynamic profile of the probe.
Целью изобретени вл етс повышение точности измерени при малых углах скоса потока и устранение автоколебаний профил пробника.The aim of the invention is to improve the measurement accuracy at low bevel angles and to eliminate self-oscillation of the probe profile.
Поставленна цель достигаетс тем, что в измерителе аэродинамический профиль выполнен из двух тон-, костенных пластин, жестко св занных с -цилиндрической частью пробника и расположенных симметрично относительно плоскости его симметрии под расход щимс углом к ней.The goal is achieved by the fact that in the meter the aerodynamic profile is made of two tone, bone plates rigidly connected with the cylindrical part of the probe and located symmetrically relative to its plane of symmetry at a diverging angle to it.
На фиг.1 изображено предлагаемое устройство, общий вид; на фиг.2 разрез А-А на фиг.1.Figure 1 shows the proposed device, a General view; in Fig.2 a section aa in Fig.1.
Измеритель направлени воздушного потока имеет цилиндрический пробник 1 со щел ми 2 и 3 дл отбора давлени встречного потока дл пневмодвигател и аэродинамического разомкнутого профил , состо ющего The air flow direction meter has a cylindrical probe 1 with slots 2 and 3 for sampling a counter-flow pressure for an air motor and an aerodynamic open-ended profile consisting
20 из тонких пластин 4 и 5, жестко св занных с пробником 1 тонкостенными стойками 6 и 7, Пластины 4 и 5 в местах сопр жени с цилиндрическим пробником 1 имеют зазоры 8 и 9. 20 of the thin plates 4 and 5, which are rigidly connected to the probe 1 by the thin-walled supports 6 and 7, the Plates 4 and 5, at the interface with the cylindrical probe 1, have gaps 8 and 9.
25 Пластины 4 и 5 установлены под некоторым углом, расход щимс к носо вой части и плоскости симметрии пробника.25 Plates 4 and 5 are installed at a certain angle, diverging to the nose part and the plane of symmetry of the probe.
Устройство работает следующим Об30 . разом.The device works as follows. at once.
