Description

[0001] The present invention relates to a thrust generator apparatus having a heterogeneous propeller at a central axis,

The present invention relates to an impulse generating device having a propeller mounted on the same central axis, and more particularly, to a propeller having a propeller for propelling a propeller And a thrust generating device.

Generally, the area surrounded by mountains and relatively high altitudes should have a lot of interest in the management of fruit trees because the temperature changes due to radiative cooling and the inflow of cold air are large compared to other regions.

In particular, the cold weather caused by the frost during the period when the orchard 's petals germinate or when the green tea grows is an important factor that influences the success of the crop farming that year.

Frost is a phenomenon in which atmospheric water vapor freezes on the surface of an object on the ground. The surface above the ground is cooled by radiative cooling, and the water vapor falling on the crop is sublimed by radiative cooling to become frost.

The cause of the frost and cold weather is caused by a structure in which the temperature of the air layer is raised from the ground surface to the ground surface for a predetermined time due to radiation cooling.

In the structure in which the temperature distribution of the air layer is increased from the ground surface to the ground surface for a predetermined time, the method of increasing the temperature of the air located in the lower layer is a method of heating by the sun at the time of sunrise or mixing with the upper air having a relatively high temperature, There is no such heating condition, so the temperature of the surface of the earth is continuously lowered until sunrise, and it can suffer cold weather.

Currently, a fan is installed on a support of a predetermined height to circulate stagnant air at the above-mentioned atmospheric temperature distribution.

However, all currently marketed fans are installed on the upper part of the orchard so that the upper air of the orchard is blown to the bottom of the orchard.

This structure blows the high temperature upper air from the stratified air layer over the low temperature lower air, which limits the circulation of the cold air layer which is in contact with the surface of the earth, and there was a lot of complaints due to loud fan noise at dawn time.

On the other hand, in the prior art of the present invention, the "upper air inflow type cold air dissipating device" of the patent registration number "10-1315247" is filed and registered, wherein the upper air inflow type cold air dissipating device comprises an air inflow fan; An air induction pipe disposed at a lower portion of the air introduction fan; A downward airflow diverging plate disposed at a lower portion of the air induction pipe; And a diverging passage coupled to a lower portion of the air induction pipe, wherein the diverging passage includes a plurality of supports, and the diverging airflow diverging plate is disposed inside the diverging passage portion support.
