Abstract
Abstract A missile destruct initiation assembly is provided that interconnects a detonator to a high-current source and contains a command destruct circuit for passing a command destruct signal to initiate detonation, and an autodestruct circuit responsive to an autodestruct signal, representative of internal missile malfunction to initiate the detonator. Thus, the assembly for initiating missile destruction performs the dual function of being responsive to a command destruct source or an autodestruct source.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
162 words
In a missile destruct initiation assembly including a potential source connected to a detonator by a gap switch, an improvement therefore is provided comprising: a command destruct circuit configured for passing a command destruct signal; means for producing a signal representative of missile acceleration; an autodestruct circuit responsive to the acceleration signal including, means for generating an autodestruct signal as said acceleration signal reaches a predetermined magnitude, first means coupled to the generating means for storing said autodestruct signal, second means for storing said autodestruct signal, clamping means in operative connection with the second storage means for impressing a hold signal, having a lesser magnitude than said autodestruct signal, thereon, and means coupling the first and second storage means for transferring said autodestruct signal therebetween upon disruption of said operative connection; and a destruct trigger circuit connecting said command destruct circuit and said second storage means to said gap switch to initiate said detonator upon receiving either one of the destruct signals.
Claim 2
Dependent Claim
162 words

Claim 3
Dependent Claim
26 words
An assembly according to claim 1 further including: interrupter means incluDed in said clamping means for ensuring said disruption of said operative connection upon missile malfunction.
Claim 4
Dependent Claim
34 words
An assembly according to claim 2 further including: inhibiting means connected to said clamping means to ensure said hold signal prior to receiving said acceleration signal at said predetermined magnitude in said autodestruct circuit.
Claim 5
Dependent Claim
41 words
An assembly according to claim 3 in which said potential source provides a biasing source to said assembly and a high current source to initiate said detonator upon ionization of said gap switch when receiving either one of said destruct signals.
Claim 6
Dependent Claim
38 words
An assembly according to claim 4 further including: an interlock simultaneously activating said biasing source, said high-current source, and said inhibiting means upon being actuated to arm said missile prior to launch and, optionally, after launch first motion.
Claim 7
Dependent Claim
43 words
An assembly according to claim 1 in which said destruct trigger circuit includes a first SCR interconnected to derive biasing and gate potentials from said command destruct signal and a second SCR interconnected to derive biasing and gate potentials from said autodestruct signal.
Claim 8
Dependent Claim
46 words
An assembly according to claim 6 in which said destruct trigger circuit includes means for passing only those said destruct signals above a trigger threshold and to inhibit the deriving of said gate potentials for both SCR''s when said destruct signals are below said trigger threshold.
Claim 9
Dependent Claim
29 words
An assembly according to claim 7 in which said destruct trigger circuit includes a plurality of interconnected SCR''s and transistors for ensuring said gate potentials of the proper magnitude.
Claim 10
Dependent Claim
29 words
An assembly according to claim 2 in which said interrupter means initiates a repetitive said autodestruct signal for ensuring conduction in said gap switch and initiation of said detonator.
