FIELD: aircraft engineering. ^ SUBSTANCE: proposed device incorporates protective elements, axially displaced and fitted in air intake casing. The latter comprises metal case, tightly fitted therein and having its chamber open into the casing. The said chamber represents, for example a hollow cylinder with end face collar bent inward and radially magnetised. The proposed device comprises also a cylindrical coil with aerodynamic-shape core arranged in the casing front part. Aforesaid coil is connected to generator of sine-wave and pulsed electric signals with controlled amplitude and frequency. Note here that protective elements represent small fragments/parts of ferromagnetic bodies, e.g. a ferromagnetic powder that fills the said case chamber. ^ EFFECT: higher efficiency of protection. ^ 1 dwg |
