RADIO FUSE ACCORD-2K FOR SALVO DELAYED ACTION BLASTING OF AMMUNITION WITH OPTICAL-ELECTRON DEVICE ACKNOWLEDGING PRESENCE OF TARGET Russian patent published in 2003 - IPC

FIELD: initiation blasting facilities, contact-free radio controlled initiation devices. SUBSTANCE: radio fuse Accord-2K can be utilized to complement rocket missile ( rockets ) of salvo fire, in guided rockets of antiaircraft rocket complexes, in guided rocket air-to-air missiles of air and rocket defense, in Air Force aviation and other type of ammunition. Radio fuse for salvo delayed action blasting of ammunition with optical-electron device acknowledging presence of selected target in space comprises following units and structural elements placed on duralumin framework of typical form: Doppler transceiver with transceiving antenna, mixer, amplifier of signal TARGET, former of electric signal BLASTING, receiving optical system with narrow-band interference light filter, photodetector, amplifiersignal former of optical receiver, AND gate, delay circuit of signal BLASTING with time delay switch, encoder of signal BLASTING, transmitter of radio command BLASTING with transmitting antenna which radiation pattern faces rear hemisphere of missile ( rocket ), receiver of radio command BLASTING with receiving antenna, decoder of signal BLASTING, OR gate, power amplifier of signal BLASTING, thyristor key, filaments of electric detonator, inertial safety electric contacts, power supply sources ( turbo- generator and ampoule storage battery ), self-destructor, safety-actuation mechanism. Salient feature of fuse is that it blasts not only warhead of missile in which it is installed but ensures emission of radio command BLASTING into space by which groups ( groups in series ) of missiles ( rockets ) are blasted, that is, salvo blasting of ammunition near target is ensured. Radio fuse Accord-2K displays infrared target selectivity, has switch taking into account closing speed of missile ( rocket ) with target and is fitted with self-destructor that secures self-destruction of missile after 0.6-1.0 ms after reception of radio command BLASTING which makes it possible to hit target even in case of failure of standard activation of radio fuse due to any cause. EFFECT: raised functional reliability of radio fuse. 2 cl, 3 dwg _
