Abstract

An initiator including a housing adapted to be received in an igniter or rocket motor, at least one charge at a distal end of the housing, an electro-explosive device behind the charge for detonating the charge when subject to a voltage HV, and a pressure bulkhead behind the electro-explosive device. An electronic subsystem in the housing is connected to the electro-explosive device through the bulkhead and includes a lead for providing the voltage HV to the electro-explosive device to initiate it, and a switch in the lead which does not conduct if errant voltages are present on the lead to prevent initiation of the electro-explosive device until the correct voltage HV is present.

Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application is a divisional application of, and claims priority to, U.S. application Ser. No. 11 / 977,068 entitled “INITIATOR”, which was filed on Oct. 23, 2007, the disclosure of which is incorporated herein by reference in its entirety.FIELD OF THE INVENTION

[0002] This subject invention relates to an initiator.BACKGROUND OF THE INVENTION

[0003] Initiators are devices including a charge initiated to ignite or begin the burning of a larger main charge or propellant.

[0004] Standards such as MIL-STD-1901A include a safety requirement to the effect that an initiator subject to 500 volts due to an errant voltage shall not detonate or deflagrate.

[0005] Although various devices for protection against errant voltages are well known, to date those skilled in the art have failed to provide a suitable initiator which meets the 500 volt no deflagration safety requirement. Previous attempts at engineering such a suitable initiator resulted in undue com...
