ONE-MAN AIR-DEFENCE GUIDED MISSILE

The present invention pertains to the field of rocketry and relates to a guided missile that belongs to the category of portable air-defence devices and is intended for the interception of low-flying targets. The missile of the present invention comprises the following members: a self-guided thermal head comprising a detector for measuring the misalignment angle between the missile longitudinal axis and the optical axis of the thermal head co-ordinator (target bearing-angle detector); a solid-fuel drive unit comprising a dual-mode cruise engine as well as an acceleration engine fitted in the launch tube; an instrumental section comprising a flight-controls actuator, an onboard power unit as well as an onboard connector for switching the electrical circuits of the missile with the launch device before launching; an explosive and fragmentation offensive load comprising a rocket functional unit that generates a pulse for triggering the electric detonator of the offensive load; and a sensor for detecting the main vortex flow of the target as well as a backup target-impact detector. In order to increase the potential of target destruction, the offensive load body comprises a target non-contacting laser detector as well as a formatter of a tuneable delay for the offensive load firing pulse. The delay of the offensive load firing pulse is tuned by the person firing the missile using switches in the launch tube and in the launch device. The delay is also tuned using an automatic switch for selecting a tracking- or encounter-type interception mode thanks to the link between the control circuit of the delay formatter and the bearing detector of the self-guided thermal head. The moment when the offensive load is fired is determined according to the selected delay value while accounting for the target speed, trajectory and dimension as well as for the interception conditions thereof (tracking or encounter). Cette invention se rapporte aux techniques des fusées et concerne un missile guidé qui entre dans la catégorie des dispositifs de défense aérienne portables, et qui permet d'intercepter une cible volant à basse altitude. Ce missile comprend une tête thermique autoguidée, laquelle possède un capteur d'angle de désalignement entre l'axe longitudinal du missile et l'axe optique du coordinateur de ladite tête thermique (capteur d'angle de relèvement de la cible). Ce missile comprend également une installation motrice à carburant solide, laquelle possède un moteur de cr
