Description

Известны приборы дл  замера статического давлени  воздуха в виде трубок Пито различных образцов. Недостатком их  вл етс  то, что они замер ют статическое давление воздуха с большими погрешност ми , завис щими главным образом от углов атаки и усугубл емыми расположением трубок в возмущенном потоке вблизи caMOvieTa. Указанные погрешности возрастают с увеличением скоростей полета, а с приближением скорости полета к скорости звука погрешности станов тс  настолько существенными, что практически не поддаютс  учету путем введени  какой-либо стройной системы поправок.Instruments are known for measuring the static air pressure in the form of Pitot tubes of various samples. Their disadvantage is that they measure the static air pressure with large errors depending mainly on the angles of attack and aggravated by the location of the tubes in the disturbed flow near caMOvieTa. These errors increase with increasing flight speeds, and as the flight speed approaches the speed of sound, the errors become so significant that they are practically incalculable by introducing some kind of coherent system of corrections.

Предлагаемое приспособление имеет целью устранение указанных погрешностей путем осуществлени  приспособлени  нечувствительным к изменению углов атаки. Последнее достигаетс  тем, что приспособление выполн етс  в виде двух параллельных близко расположенных дисков (основного и экранирующего), устанавливаемых параллельно потоку, причем отверстие, воспринимающее статическое давление, делаетс  во впутренней поверхности (например, в центре) основного диска.The proposed fixture aims at eliminating the indicated errors by making the adjustments insensitive to changes in the angle of attack. The latter is achieved by the fact that the device is made in the form of two parallel closely spaced disks (main and shielding) installed parallel to the flow, and an orifice that perceives static pressure is made in the inner surface (for example, in the center) of the main disk.

Па чертеже схематически изображено предлагаемое приспособление в трех проекци х.Pa drawing shows schematically the proposed fixture in three projections.

Приспособление состоит из диска / и экранирующего диска 2, расположенных близко друг к другу и устанавливаемых параллельно потоку . Диск / имеет на внутренней поверхности отверстие 3, расположенное , например, в его центре, которое воспринимает статическое давление потока. Благодар  тому, что статическое давление замер етс  не на наружной поверхпости, насадка, обтекание которой весьма неустойчиво, а в «канале, образованном внутренними поверхност ми дисков / и 2, где поток устойчив, погрещности, обусловливавшиес  возмущением потока , устран ютс .The device consists of a disk / and a shielding disk 2, located close to each other and installed in parallel to the stream. The disk / has on the inner surface of the hole 3, located, for example, in its center, which perceives the static pressure of the flow. Due to the fact that the static pressure is not measured on the outer surface, the nozzle, the flow around which is very unstable, but in the channel formed by the inner surfaces of the disks I and 2, where the flow is stable, the faults caused by the flow disturbance are eliminated.

В результате того, что предлагаемое приспособление устанавливаетс  параллельно потоку, оно оказываетс  совершенно нечувствительным к изменени м угла атаки самолета, так как при любых углах атаки оно остаетс  параллельным самому себе.As a result of the fact that the proposed fixture is installed parallel to the flow, it is completely insensitive to changes in the angle of attack of the aircraft, since at any angle of attack it remains to itself.

Предмет изобрете ни  Subject to invention

Приспособление дл  замера статического давлени  в полете на больших скорост х, выполненное в виде устанавливаемого вертикального круглого диска с отверстием в центре, соединенным с индикатором, отличаю щ.е е с   тем, что, с целью осуществлени  замера в услови х, аналогичных замеру в закрытом потоке, и нечувствительного к углам атаки, в непосредственной близости от диска параллельно ему, со стороны отверсти  расположен дополнительный экранирующий диск.A device for measuring static pressure in flight at high speeds, made in the form of an installed vertical circular disc with a hole in the center connected to the indicator, is different because, in order to measure it under conditions similar to that in closed stream, and insensitive to angles of attack, in the immediate vicinity of the disk parallel to it, from the hole is an additional shielding disk.
