866,698. Projectile fuzes. CONTRAVES A.G. March 12, 1959 [March 12, 1958], No. 8569/59. Class 9(1). A missile G provided with a trailing wire connection D to an electrical control installation L,whereby the trajectory of the missile may be corrected for variations in pitch and yaw, comprises a safety device to prevent arming of the fuze until an arming signal is received from the installation L. Trajectory correc-. tions Mn, My made by an operator are converted by transducers Wn Wy to electric signals En, Ey respectively and conveyed by a device K1 and cable D to a device K2 within the projectile. Device K2 separates the signals and conveys them to transducers Vn, Vy which convert the signals into mechanical forces to adjust the steering mechanism of the projectile. In addition, the installation L comprises a transducer Wa for conveying an arming signal through device K1 and cable D to the device K2 which conveys the signal to a transducer Va. The transducer Va converts the signal into a voltage - Va to operate a transistor Ta which serves as an electronic control switch, the voltage being applied to the base electrode of the transistor. Until an arming signal is received, the transistor is non- conductive and forms an open switch in the circuit of a battery Bt connected to a solenoid Ma. On receipt of the arming signal, the transistor Ta becomes conductive, the solenoid is energized and withdraws a shield Ha leaving the charge HL exposed to the detonator Z1. A cam surface on the shield HL closes a switch As as the shield is withdrawn and, on impact, an inertia mass St moves forward closing a switch Zs to complete the circuit from the battery Bt. Thus the detonator Z1 is fired and ignites the charge HL. Charge HL may be a hollow charge and the missile may be self-propelled. A second detonator Z2 may be arranged in parallel with the detonator Z1, this second detonator being provided to blow off the nose of the shell. Amplifying transistors may be provided for stepping-up the in-put voltage between transducer Va and the transistor Ta.
