Abstract

In this homing device, the side nozzles of the gas propulsion unit can be opened independently of one another. The device comprises a gas generator, preferably using solid propellant, and means to control the shutting and opening of nozzles, these means comprising, for each nozzle, an electromagnetic device controlled independently of the electromagnetic devices of the other nozzles. Provision can be made for a spring giving the power needed to close a nozzle, the electromagnetic device being actuated only to open the nozzle. Among the control means, the invention also provides for a control piston actuated by the electromagnetic device which brings a pressure chamber, within which there is a sliding piston, into contact either with the open air or with the gases coming from the gas generator. The control means are also arranged in such a way as to act as safety valves, in order to avoid the untimely explosion of the gas generator in the event that none of the nozzles is open.
