Abstract:

The continuing effectiveness of the vaporiser fuel injection system is demonstrated in such engines as the Olympus 593 in Concorde, the Pegasus in Harrier and the RB199 in Tornado. Its potential is illustrated by its selection for the RB211-Ce3 advanced technology demonstration engine but, like other fuel injection systems, it is subject to increasingly severe demands and duties resulting from the imposition of emissions legislation, increasing engine pressure ratios, and reducing fuel quality. To meet these new challenges requires more detailed knowledge of the factors which determine how the device functions. The present paper describes a spark photographic study of a vaporiser efflux in combusting and non-combusting environments at pressures up to five atmospheres. At simulated engine idle conditions the two mechanisms of fuel heating within the vaporiser wall and airstream combine to produce a highly vaporised efflux. Author
