Description
Предметом изобретени вл етс способ измерени с движущегос объекта, например самолета, размера и количества частиц облаков и осадков по заданным интервалам их спектрального распределени , а также водности облаков и осадков.The subject of the invention is a method for measuring from a moving object, such as an aircraft, the size and number of particles of clouds and precipitation at predetermined intervals of their spectral distribution, as well as the water content of clouds and precipitation.
Известные дл этой цели способы сложны, трудоемки и не позвол ют получать непосредственно в полете, без последующего лабораторного анализа вз тых проб, сведени о размере и количестве частиц но заданньш интервалам нх спектрального распределени , а также водности облаков и осадков. Кроме того, известные способы не пригодны дл измерени размера и количества частиц облаков и осадков радиусом более 50j,i.The methods known for this purpose are complex, time consuming and do not allow to obtain directly in flight, without subsequent laboratory analysis of the samples taken, information about the size and number of particles but given intervals of their spectral distribution, as well as the water content of clouds and precipitation. In addition, the known methods are not suitable for measuring the size and number of particles of clouds and precipitation with a radius of more than 50j, i.
Описываемый способ свободен от указанного недостатка.The described method is free from this drawback.
По этому способу о количестве частиц в том или ином интервале снектра размера частиц суд т но интенсивности и количеству электрических импульсов, возникающих при соударении частиц с высокочувствительным электрическим датчиком давлени , например, ньезокварцевой пластинкой или электроакустическим микрофоном, подключенным через усилитель, настроенный на определенную полосу частот, к осциллографу или амплитудному анализатору со счетчиками импульсов, лежащих в определенных пределах, а о водности облаков и осадков суд т по величине интеграла, вз того но полученной на осциллограмме кривой записи импульсов или по показани м интегрирующего электроизмерительного нрибора, подключенного через усилитель к датчику давлени .According to this method, the number of particles in one or another interval of the particle size spectrum was determined by the intensity and number of electrical impulses arising from the collision of particles with a highly sensitive electric pressure sensor, for example, a quartz-plate or an electro-acoustic microphone connected through an amplifier , to the oscilloscope or amplitude analyzer with pulse counters lying within certain limits, and the water content of clouds and precipitation is judged by the value of taken on the oscillogram of the pulse recording curve or from the indications of an integrating electrical measuring device connected through an amplifier to a pressure sensor.
При измерении мелких капель, интенсивность импульса которых от соударени сдатчиком равна интенсивности носторонних шумов, примен ютс два датчика давлени , включенные но мостовой схеме, таким образом, чтобы компенсировались напр жени , создаваемые одновре№ 115699When measuring small droplets, the pulse intensity of which from the impactor is equal to the intensity of side noise, two pressure sensors are used, connected on a bridge circuit, so that the stresses generated simultaneously by 115699 are compensated.
медно обоими датчиками, и измер лись давлени , действующие на датчики неодновременно.both sensors, and the pressures acting on the sensors at the same time were measured.
Размер площади датчика беретс таким, что веро тностью одновременного соударени , нескольких частиц с датчиками, определ емой площадью датчика, частиц и их концентрацией, практически пренебречь,. При производстве измерений учитываетс скорость самолета, от которой завй.сит объем воздуха, вырезаемый приемником давлени .The size of the sensor area is taken such that the probability of a simultaneous impact of several particles with sensors, the sensor area, particles, and their concentration, is practically neglected. When making measurements, the speed of the aircraft is taken into account, from which the air volume cut by the pressure receiver is reduced.
