Abstract

Proposed solution allows to turn multicopter into air suction or air blowing machine without use of additional pumps or propellers and thus avoiding significant increase of mass and battery consumption. This is achieved by placing iris diaphragms (3) above or below propellers (1) and using them for controlling partial sealing of copter frame (2), directing air flow into tubes (4) which are connected to main tube (5). Solution can be applied to various tasks which require vacuum cleaning or air blow: domestic vacuum cleaning, industrial vacuum cleaning, urban park air blower, etc.

Description

MULTICOPTER WITH INTEGRATED MECHANISM OF AIR SUCTION AND AIR BLOW
DESCRIPTION Technical Field
The proposed solution belongs to aviation, in particular to the group of unmanned aerial vehicles with few propellers - multicopters.
The solution allows to turn multicopter into air suction or air blowing machine without use of additional pumps or propellers and thus avoiding significant increase of mass and battery consumption.
Background Art
Previously multicopters were not used for specified purposes, so there is no prototype or similar device known to us.
Disclosure of Invention
The desired effect is achieved by placing one ore more iris diaphragms above or below propellers and using them for controlling partial sealing of copter frame and directing air flow into tubes for achieving the effect of air suction or air blow.
Main elements of the mechanism are shown on the provided drawings. In particular we show multicopter with 4 propellers (1), each propeller is placed into semi-closed frame (2), iris diaphragms (3) are placed above and below each propeller, tubes (4) are connecting frame with main tube (5). Additionally effective air direction is shown by arrows on the drawings 2, 3, 4.
Principle of operation is described below.
When diaphragms are fully open, multicopter is in its usual fly mode, air flow is not limited, the effects of air suction and air blow are absent, which is depicted on figure 1 .
When UPPER diaphragms are closed, multicopter is in air suction mode, which is depicted on figure 2.
When BOTTOM diaphragms are closed, multicopter is in air blow mode, which is depicted on figure 3.
When diaphragms are closed, multicopter is loosing thrust and starts to move down. To avoid this effect diaphragms can be closed by short impulses during which the desired effect of air suction or air blow will happen.
Also it's possible to PARTIALLY close diaphragms with simultaneous throttle increase. In this case lost of thrust would be fully or partially compensated, which is depicted on figure 4. The goal and main advantage of the proposed solution is the ability to achieve the effect of air suction and air blow by using existing propellers without a need to install additional compressor that would cause significant mass and battery consumption increase.
Brief Description of Drawings
Figure 1 : Top front view, diaphragms are fully open, multicopter is in its usual fly mode, air flow is not limited, the effects of air suction and air blow are absent.
Figure 2: Top front view, upper diaphragms are closed, multicopter is in air suction mode.
Figure 3: Bottom front view, bottom diaphragms are closed, multicopter is in air blow mode.
Figure 4: Top front view, diaphragms are partially closed which allows to achieve both air suction effect and thrust preservation.
Best Mode for Carrying Out the Invention
Diaphragm rotation for its closing or opening can be implemented using drive mounted into the frame. The specific diaphragm construction or number of its blades is not of fundamental importance.
Solution also does not depend on the number of multicopter propellers and can work with any number of them. Different number of propellers can be used to help to find optimal balance between suction power & thrust preservation (when diaphragms are semi-open).
Tubes for incoming or outcoming air flow can be placed above the propellers, as shown on the figures, or on the sides of the frame. The point of tube connection to the frame is a question of external design and is not important for mechanism operation.
Industrial Applicability
The solution can have many possible applications, few most important in our opinion are:
* Domestic drone for vacuum cleaning the house that can reach all surfaces
* Industrial drone for fighting pests on the fields in organic way
* Municipal drone for cleaning streets and parks (remove dry leaves, etc.)

Claims

Multicopter characterized by having one or more iris diaphragms positioned above or below propellers and used for controlling partial sealing of copter frame and directing air flow into tubes for achieving the effect of air suction or air blow.
