A radiation emitter for a projectile comprises a pyrotechnical charge located within the body of the projectile, and connected via a channel within the body to an opening in the side of said projectile to emit radiation via said opening when the pyrotechnical charge has been ignited. The radiation emitter may comprise the transmitter unit of a proximity fuze carried by the projectile.

Device for emitting radiation, for a projectile, shell etc.

A projectile comprises an elongated casing containing a payload, a proximity fuze, a transmitter unit operative to transmit a beam of radiation toward a target, and a receiver unit responsive to radiation reflected from the target for controlling the proximity fuze to selectively initiate operation of the payload at a predetermined distance from the target. The transmitter unit is located adjacent the tail end of the projectile rearward of the payload and comprises a pyrotechnical charge positioned at the extreme rear of the projectile and operative, when ignited, to cause emission of light via a lens in an opening in the side of the projectile to form the transmitted beam of radiation. The receiver unit is located adjacent the nose end of the projectile forward of the payload to maximize the measuring base between the transmitted and received beams of radiation, and comprises an optical system associated with an interference filter, radiation detector, and electronic control circuit.

Carrying part forming a projectile

A projectile of the type containing a payload and a heat source spaced from said payload and activated while the projectile is in flight, is provided with a power-generating device comprising a number of thermo elements which are connected in series at a plurality of hot and cold junctions. The hot junctions are disposed adjacent the heat source within said projectile, and the cold junctions are spaced from said heat source and located adjacent the payload. The heat source may constitute a source of radiant energy associated with the transmitter portion of a proximity fuze, and the power-generating device may in turn energize the receiver portion of the fuze to control initiation of the payload.
