<p>A petroleum derived fuel, e.g. natural gas/paraffin, is ignited in air within a hollow tubular body 2 and a resulting expanding conductive fluid ignition product is expelled from an outlet 8 of the hollow body 2 to produce thrust. The jet engine 1 uses a travelling wave magnetic field produced by a linear motor 11 to control the expansion of the fluid ignition product, accelerating the fluid ignition product, through acceleration zone 7, to produce thrust. The linear motor 11 comprises several magnetic field coils 12 axially spaced along the acceleration zone 7. The engine1 may include a second set of coils 13 downstream of the acceleration zone 7, which induce a current as the accelerated ignition product passes, the current being used to recharge the capacitor/battery 12A.</p> |
