A device is configured for deflecting a stream of particles for a projectile guided by a link wire, the projectile having a fuselage and an engine capable of producing a propulsive jet containing the stream of particles. The device includes a device support including an inner surface configured to attach the device support to the fuselage of the projectile, and a deflector strip assuming at least an unfolded position in which the deflector strip forms an angle with the device support in order to deflect the stream of particles.

Provided in some embodiments is a method of deploying a payload in a subterranean well. The method including advancing a torpedo in a first portion of a wellbore of a subterranean well (the torpedo including a body, a fiber-optic (FO) umbilical that is physically coupled to a surface component, and adapted to unspool from the torpedo as the torpedo advances in the wellbore, and an engine adapted to generate thrust to propel the torpedo), and activating the engine to generate thrust to propel advancement of the torpedo within a second portion of the wellbore such that the FO umbilical is disposed in the second portion of the wellbore.

A power system is disclosed that includes a chassis configured to house a first board, a second board, and a third board, in which the boards are electrically coupled to one another. The first board is configured to receive power and to output power at a first voltage and a second voltage. The second board is configured to receive power from the first board or at least one internal battery electrically coupled to the second board and to output power using at least two voltages. The third board is configured to receive power from the second board and to output power at two voltages. The boards include one or more converters configured to convert power. The one or more converters are thermally interfaced with one or more portions of the chassis so as to conduct heat into a respective portion of the chassis.
