PURPOSE: A heat sensing igniter, a heat sensing automatic lighter, and a flight vehicle including the same are provided to mitigate a danger by sensing fire for automatically igniting and normally combusting a propellant ahead of the intense reaction of the propellant in the event of fire. CONSTITUTION: A heat sensing igniter comprises a housing, a signal gunpowder filler, a first sub gunpowder part, a first cover part, and a second cover part. The signal gunpowder filler is filled into the housing at a regular pressure and is ignited when being heated to a first or higher temperature. The first temperature indicates 130-150 degrees Celsius. The heat sensing automatic lighter comprises first and second bodies, a fire gunpowder part, an electric initiator, and a heat sensing igniter. The first and second bodies are joined to a propulsion unit in order to ignite a solid propeller. The ignition temperature of the first and second bodies is 220-240 degrees Celsius. |
