Title:
CONDUCTIVE SOLID FUEL, IGNITION DEVICE, METHOD FOR PRODUCING SAME, IGNITION METHOD AND ROCKET COMBUSTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/074532
Kind Code:
A1
Abstract:
An ignition device 30 is provided with a housing 31, a bulk fuel 40, and at least two lead wires 50 that serve as electrodes. The bulk fuel 40 is formed of a plastic material such as a polylactic acid (PLA) and an epoxy resin. The bulk fuel 40 contains a conductive substance in a powder form, the conductive substance being dispersed in the bulk fuel 40, thereby enabling the achievement of a conductive solid fuel. One end of each lead wire 50 is partially buried in the bulk fuel 40. The other end of each lead wire 50 is connected to a power supply (not shown in the drawing). Some of the bulk fuel 40 is gasified by having a current passed through the lead wires 50, and a gasified fuel 42 is combusted through a reaction with an oxidant OX. Due to this configuration, the present invention enables, with a simple structure, the achievement of ignition that is excellent in terms of reignition performance, safety management, heat management and reliability.
