Abstract
The invention discloses a small-sized gas generating device for an unmanned aerial vehicle parachute, which comprises a container 1, an ignition head 2 and a control panel 3, and is characterized in that: the container comprises an ignition head 2, ceramic fiber paper 4, gas generating agent 5 and flame control agent 6, the bottom of the container is provided with an ignition head control plate 3, and the top of the container is sealed with a silica gel sheet 7. The ceramic fiber paper 4 in the container 1 has a fireproof effect, the ignition head 2 is controlled by the control panel 3, and after the control panel 3 sends out an instruction, the ignition head 2 quickly ignites the gas generating agent 5, so that enough gas is generated to spray the parachute. The invention has the advantages that: simple structure, small volume, fast reaction speed and good umbrella opening effect.
Description
Technical Field
The invention relates to the field of unmanned aerial vehicle parachutes, in particular to a small gas generating device for an unmanned aerial vehicle parachute.
Background
Along with the growth in the unmanned aerial vehicle market, unmanned aerial vehicle safety problem arouses people's concern more and more, and the damage that unmanned aerial vehicle parachute can effectually reduce the unmanned aerial vehicle and fall, and the main use of present unmanned aerial vehicle parachute opening system is the mode of launching the parachute, and its mode of launching has the structure complicacy to influence duration, launches defects such as parachute opening time overlength, mechanical failure rate height.
Disclosure of Invention
The invention aims to solve the problem of the defects and provides a small gas generating device for an unmanned aerial vehicle parachute.
The technical scheme adopted for realizing the purpose is as follows: the utility model provides a small-size gas generator for unmanned aerial vehicle parachute, includes container, ignition head, control panel, its characterized in that: the container comprises an ignition head, ceramic fiber paper, a gas generating agent and a flame control agent, the bottom of the container is provided with a control plate, and the top of the container is sealed with a silica gel sheet.
A small-size gas generator for unmanned aerial vehicle parachute, gas generator is H type nitrocotton.
A small-size gas generator for unmanned aerial vehicle parachute, flame control agent contains NH4H2PO4、(NH4)SO4And talc.
The invention has the advantages that: simple structure, small volume, fast reaction speed and good umbrella opening effect.
Drawings
FIG. 1 is a schematic view of a small gas generator for a parachute of an unmanned aerial vehicle according to the present invention;
wherein: 1. a container; 2. an ignition head; 3. a control panel; 4. ceramic fiber paper; 5. a gas generating agent; 6. a flame control agent; 7. a silica gel sheet.
Detailed Description
The invention will be described in further detail with reference to the accompanying drawings and embodiments.
Referring to fig. 1, a small-sized gas generating device for an unmanned aerial vehicle parachute according to an embodiment of the present invention includes a container 1, an ignition head 2, and a control panel 3, and is characterized in that: the container comprises an ignition head 2, ceramic fiber paper 4, gas generating agent 5 and flame control agent 6, the bottom of the container is provided with an ignition head control plate 3, and the top of the container is sealed with a silica gel sheet 7. The ceramic fiber paper 4 in the container 1 has a fireproof effect, the ignition head 2 is controlled by the control panel 3, and after the control panel 3 sends out an instruction, the ignition head 2 quickly ignites the gas generating agent 5, so that enough gas is generated to spray the parachute.
A small-size gas generator for unmanned aerial vehicle parachute, gas generant 5 is H type nitrocotton. The gas generating agent 5 is combusted to generate sufficient gas to be ejected by the parachute.
A little for unmanned aerial vehicle parachuteIn the gas generator, the flame control agent 6 contains NH4H2PO4、(NH4)SO4And talc. The flame controller 6 can effectively control the flame generated by the combustion of the gas generating agent 5, prevent the parachute from being burnt by the flame, and reduce the potential safety hazard of the combustion.
It will be apparent to those skilled in the art that modifications and equivalents may be made in the embodiments and/or portions thereof without departing from the spirit and scope of the present invention.
