DE595046C - Evaluation device for wind pilots - Google Patents

Description

Used to determine · the direction and strength of the wind in the successive The devices used in elevation are called balloon theodolite combinations one - 5 sighting device with a device that is used to record the horizontal projection of the with Constant speed ascending and thereby steadily targeted pilot balloons is used. Due to their complicated design, such balion theodolites are expensive and therefore often especially for the smaller weather stations, not available. In contrast the usual surveying theodolites on the market are relatively cheap and allow the optical tracking of an ascending pilot baEon is just as accurate as the expensive balloon theodolites.

In order to make the latter dispensable, the aim of the invention is to use of an ordinary survey theodolite a rapid evaluation of the wind piloting through continuous measurements of the elevation and side angles of a known one at the same time at the same time constant speed on ascending pilot balloons obtained by their Transfer to a with or without preprinted horizontal circle division and useful Drawing sheet provided with a parallel line grid to determine the size and direction of the wind speed in the individual layers of the atmospheric air. .

Evaluation devices for other purposes are already known which consist of a degree curve and a pivotable radial heal on which a ruler extending at right angles thereto can be moved longitudinally. According to the invention, such an evaluation device for solving the aforementioned problem is primarily designed in that, on the one hand, one leg of the qua, dranten a radial, through the zero point of the heights angle division pulling setting edge as a hypothenuse of the folded target height triangle, on the other hand, on the pivotable Radial arm, the height and the lateral angle setting mark is arranged, and thirdly, the ruler which is longitudinally displaceable on this radial arm and extends at right angles to it carries a height graduation numbered with measuring times. The center of the quadrant, the zero point of the vertical division and the lateral angle and elevation angle setting mark are therefore on the
Radius.

The invention also relates to embodiments of one of the aforementioned three combination features having evaluation device.

The drawing shows the subject matter of the invention in two exemplary embodiments men, namely: Fig. 1 is a plan view of a device for using wind blades with. preprinted side angle division and Fig. 2 is a plan view of a device with concentric sides angled graduation ring for · the use of wind sheets without preprinted Side angle division.

The subject matter of the invention essentially consists of a

same

division from o ° to the right angle provided quadrant A ₁ QA ₂ , the legs of which ^ is provided with a radial adjustment edge K running through the zero point of the elevation angle division, and a radial ruler B rotatable around the center of the quadrant by means of a pin 3 designed as a pin on which there is arranged radially displaceable on this vertical height ruler C by means of a guide rail, D. This height ruler C is equipped with a height graduation, which, however, is expediently numbered according to the time minutes in which the plotted heights are reached by the pilot balloon of known rate of climb. So z. B. with a drawing scale of ι = 25,000 and a rate of climb of 150 m / min, on this measuring time division iMin. = I5oooomm: 25,000 = 6mm. The zero point of this division is equipped with a spring-loaded pike needle P , that is, one that is pulled out of the drawing sheet in a known manner after pricking has taken place with a finger pressure. Also, the radial ruler B is provided with a pitch of the display as a map distance division on the scale of Eg ι mm = 25 na removal by the Pikiernadel / ³ labeled root of the pilot balloon from the labeled through the center S observer. This radial ruler B also bears the setting mark M for the elevation angle division H and the setting mark N for the lateral angle division L in the radial direction SP . This device is easy to use. Immediately next to the theodolite is the map table with the drawing sheet attached to it, with or without a preprinted angle division.

In the first case (Fig. 1), the quadrant is attached concentrically to the preprinted side angle division L and above it the rotatable radial ruler B with the Piki needle S. In the second case, if no pre-printed side angle division exists, the azimuth angle pitch L supporting metal ring /? (see Fig. 2) placed on the parallel line grid in such a way that a straight line of this grid coincides with the diameter passing through the zero point of the lateral angle division and is attached to the map table _{by means of two pricking pins} / _{l3 / 2 provided on the lower surface of the ring.} The precisely fitted elevation angle arc Q ₁ with its radial arm is then mounted in this ring, expanded to a semicircle or full circle, as in the former case.

The radius passing through the zero point of the lateral angle division gives the main direction z. B. South, after which the pilot "theodolite with its lateral direction zero during the measurements is oriented.

Now hold the pilot balloon balanced to a known rate of climb at most at a certain measured distance, e.g. B. 50 m from the theodolite, in its horizon, determines the lateral angle to the zero direction and rotates the radial ruler B so far that this lateral angle is indicated with the mark N at the division L , whereupon the radial ruler is set on the map by means of the 'Pikiernadel F' will. Then the height ruler C slidably mounted on it is shifted so far that. its setting mark on the map distance graduation B _{1 shows} the distance 50 m = 2 mm, whereupon the starting point of the base path of the pilot balloon is marked on the map ^{by pressing the pike needle / 3.}

Now the pilot balloon is released and its location after the same times have elapsed (e.g. minutes) determined by means of the theodolite by adding elevation and elevation angles can be read, noted and called out at the same time as the measuring times are called out.

Then set the radial ruler B to the lateral angle σ of the division L using the setting mark N, set it with the needle / ⁷ and turn the elevation angle arc or quadrant Q or Q ₁ by means of its grip pin G so far that the elevation angle α is on the division / / dx is covered by the setting mark M. Now the height ruler C must always be moved so far on the radial ruler B that the graduation line corresponding to the last number of minutes on the division C _{1 is cut} by the setting edge K. of the arm A ₁ , whereupon the spike needle P is pressed down. The connecting line of all punctures of this needle gives the foot point trajectory of the pilot balloon, from which one can determine not only the direction related to the zero direction (parallel line grid), but also the horizontal speed of the pilot balloon and thus also of the wind (by the distance of neighboring punctures).
