For special applications, pyrophoric igniters can be used which burst into flame in contact with air. Triethylborane /TEA-TEB was used as an igniter for the Lockheed SR-71 jet engines, the Rocketdyne F-1 engine on the first stage of the Saturn V, NPO Energomash's RD-180 engine used on the first stage of the Atlas V, and SpaceX's Merlin engine ...
Laser ignition is considered as a potential ignition system for non-hypergolic liquid rocket engines, [4] [5] reaction control systems [6] [7] [8] and firearms [9] which need an ignition system. Conventional ignition technologies like torch igniters are more complex in sequencing and need additional components like propellant feed lines and ...
Electric matches before, during and after ignition. An electric match is a device that uses an externally applied electric current to ignite a combustible compound.. Electric matches use a bridgewire consisting of a heating element to ignite a pyrogen, which is a quantity of readily ignited pyrotechnic initiator composition.
This fuse is used in high-power model rocketry as a means of simultaneously igniting multiple "clustered" rocket motors. A single flashbulb or flash pan is used to ignite pieces of Thermalite leading to each motor. [1] Thermalite comes in three burn rates identifiable by the colour of the fuse wrapping: Pink: slow (20 sec/foot)
Reloadable rocket motors are specified in the same manner as single-use model rocket motors as described above. However, they have an additional designation that specifies both the diameter and maximum total impulse of the motor casing in the form of diameter/impulse. After that, there is a series of letters indicating the propellant type.
Estes model rocket motors are lit by a type of electric match. Large fireworks displays are launched with complex timing sequences using a computer that energizes electric matches connected to the individual device fuses. A flying fish fuse (bumblebee) is an unusual type of component for fireworks. It is made like Visco fuse, but contains a ...

The designation for a specific motor looks like C6-3.In this example, the letter (C) represents the total impulse range of the motor, the number (6) before the dash represents the average thrust in newtons, and the number (3) after the dash represents the delay in seconds from propelling charge burnout to the firing of the ejection charge (a gas generator composition, usually black powder ...
