Recent events have highlighted the fact that none of the currently available turboshaft intake protection systems, whether they be the permanent fit IPS or mission specific vortex pack types, have an adequate sand/dust separation capability. Evidence has been amply provided by low engine lifes, consequent support logistics problems and the necessity for development of short term emergency measures. The paper seeks to quantify the extent of the problem and define the solutions which will be required if a repeat of past experiences is to be avoided. Ths paper describes the direction which particles separator technology must take in order to meet future requirements. A further important aspect of future directions is the drive for an increase in an engines ability to resist damage; the paper identifies those areas of the engine which are most prone to damage, comments on the need to strike the right balance between resistance and removal, and discusses the increasing value of sophisticated computer based design methodologies.
