<p>A pre-heating unit for a liquid fuel turbine for model aircraft comprises: - a body (14) which can be inserted by at least one of its ends in a combustion chamber of a turbine, and in which there is determined a fuel path which is determined between a fuel intake aperture (5) and a fuel outlet aperture (16), the said fuel intake aperture being in fluid communication with means to feed pressurized liquid fuel, and the said outlet aperture being positioned inside the combustion chamber of the turbine; - glow means (18) which are positioned along the said fuel path in order to heat the fuel to above its ignition temperature; and - nebulisation means (19) which are positioned along the said fuel path in order to obtain discharge of nebulised fuel from the said outlet aperture. Advantageously, the said preheating unit makes it possible to carry out starting of the turbine without requiring the use of gas or another fuel, other than that used for normal functioning of the turbine.</p> |
