Description
Определение скорости и направлени поверхностного течени в мелководных районах мор можно производить при помощи аэрофотосъемки и поплавков с красителем.Determining the speed and direction of surface currents in shallow areas of the sea can be made using aerial photography and dye floats.
Известные способы аэрофотосъемки требуют создани неподвижных ориентиров, позвол ющих определ ть изменени во времени координат поплавков, или применени радиогеодезических средств, позвол ющих определ ть координаты самолета и исключать их изменени во времени, что ограничивает возможность их практического применени .The known methods of aerial photography require the creation of fixed landmarks that allow determining the changes in time of the coordinates of the floats, or using radio geodetic tools to determine the coordinates of the aircraft and eliminate their changes in time, which limits the possibility of their practical application.
Предлагаемый способ свободен от указанных недостатков.The proposed method is free from these disadvantages.
Это достигаетс в результате того, что с самолета сбрасывают патрон , зар женный двум поплавками, которые по достижении патроном дна мор автоматически всплывают на поверхность через заданные промежутки времени. Фотографиру эти поплавки, можно по длине и направлению линии, соедин ющей поплавки на аэроснимке, определить скорость и направление течени .This is achieved as a result of the fact that from the aircraft they drop a cartridge charged with two floats, which, when the cartridge reaches the bottom of the sea, automatically float to the surface at specified time intervals. By photographing these floats, it is possible to determine the speed and direction of the flow from the length and direction of the line connecting the floats in the aerial photograph.
Указанный способ основан на том, что рассто ние между поплавками на поверхности мор зависит от времени встглыти второго поплавка относительно первого и от скорости течени в данной точке мор . Зна рассто ние-между поплавками и интервал времени между выбросами на поверхность первого и второго поплавков, можно по известным формулам ВЫЧИСЛИТЬ скорость течени .This method is based on the fact that the distance between the floats on the surface of the sea depends on the time it takes to swim the second float relative to the first and on the speed of the current at this point of the sea. Knowing the distance between the floats and the time interval between the emissions of the first and second floats to the surface, one can compute the flow rate using known formulas.
Направление течени определ етс по аэроснимку, ориентировка которого известна.The direction of flow is determined from an aerial photograph, the orientation of which is known.
Дл лучщего распознавани поплавков на поверхности мор верхнюю часть их пропитывают крас щим веществом - флуоресцеином.In order to better recognize floats on the surface of the sea, their upper part is impregnated with a dye fluorescein.
Предмет изобретени Subject invention
Способ определени скорости и направлени поверхностного течени в мелководных районах мор при помощи аэрофотосъемки и поплавков-с красителем, отличающийс тем, что сбрасывают с самолета патрон, зар женный двум поплавками, которые по достижении патроном дна мор автоматически всплывают на поверхность через заданные промежутки времени, фотографируют поплавки и суд т о скорости и направлении течени по длине и направлению линии, соедин ющей поплавки на аэроснимке.The method of determining the speed and direction of surface currents in shallow water areas of the sea using aerial photography and dye floats, characterized in that they drop a cartridge loaded with two floats from an aircraft that automatically float to the surface at specified intervals of time and photograph floats and judging the speed and direction of flow along the length and direction of the line connecting the floats in the aerial photograph.
