Abstract
An igniter, an ignition method and a method of assembling an ignitor are provided. In one embodiment, the igniter includes a first member having an inner surface. The igniter also includes a second member having an outer surface engaged with the inner surface when in an assembled configuration and forming a space between the inner surface and the outer surface. The igniter further includes an ignition charge disposed in the space. The second member is configured to move with respect to the first member when in the assembled configuration so as to apply a predetermined pressure, which includes a shear force and a compressive force, to the ignition charge to ignite the ignition charge. According to various embodiments, ignition of the ignition charge is improved.
Claims9
An igniter comprising:
- a first member having an inner surface;
- a second member having an outer surface engaged with the inner surface when in an assembled configuration and forming a space between the inner surface and the outer surface;
- and
- an ignition charge disposed in the space,
- the second member being configured to move with respect to the first member when in the assembled configuration so as to apply a predetermined pressure, which includes a shear force and a compressive force, to the ignition charge to ignite the ignition charge.
An ignition method comprising:
- providing an ignitor having a first member and a second member, the first member having an inner surface, the second member having an outer surface engaged with the inner surface and forming a space between the inner surface and the outer surface, an ignition charge being disposed in the space;
- and
- applying a pressure, which includes a shear force and a compressive force, to the ignition charge to ignite the ignition charge.
A method of assembling an ignitor, the method comprising:
- providing a first member having an inner surface;
- providing a second member having an outer surface;
- inserting the second member into the first member so as to form a space between the inner surface and the outer surface;
- and
- pouring an ignition charge when in a slurry form into the space, the ignition charge drying after being poured into the space so as to ignite when a predetermined pressure is applied to the first member.
An igniter comprising:
- a first member having an inner surface;
- a second member having an outer surface engaged with the inner surface and forming a space between the inner surface and the outer surface when in an assembled configuration;
- and
- an ignition charge disposed in the space,
- wherein one of the first member and the second member is configured to be moved relative to the other one of the first member and the second member when in the assembled configuration to ignite the ignition charge by applying a predetermined pressure to the ignition charge.
