| 摘要 | An igniter system for solid propellant type rockets and is designed to ignite the propellant over a wide range of temperature conditions. The system consists of a pair of igniters in circuitry with a power source. A thermostatic switch in the firing circuit acts upon a low temperature condition to permit firing of both igniters and upon high temperature, only one igniter. | ||||||
| 权利要求 | 1. In combination with a missile: a propellant motor comprising a. a casing b. a hollow propellant grain in said casing; c. a plurality of elongated igniters laterally spaced from each other and housed completely within the interior space of said propellant grain in parallel relation to the longitudinal axis of said propellant grain; each of said igniters having a casing, an igniting charge within said casing, a pair of electrical leads, and means for preventing non-electrical ignition of said igniting charge; d. a firing circuit for electrically igniting one of said igniters; and e. at least one supplemental firing circuit for electrically igniting at least one other of said igniters, said supplemental firing circuit being operable only below a predetermined ambient temperature; whereby said propellant grain may be ignited by said firstnamed igniter when the ambient temperature is not less than said predetermined temperature, and by a plurality of said igniters when the ambient temperature is below said predetermined temperature. 2.
