An inceasing number of successful demonstrations of ceramics as significant structural components in small land based heat engines, especially gas turbines, has drawn the attention of small aircraft and missile engine designers to this class of materials. The question which is being asked with increasing frequency is: 'Do ceramics measure up to the criteria and requirements of airborne engines?' This question obviously does not have a simple answer, mainly because of the wide range of systems requirements and duty cycles which exist amongst airborne engines themselves. In this paper the engines with different duty cycles. The general design criteria and associated key materials and requirements for generic engines for limited life, APU, and man-rated helicopter use will be addressed. Materials, processes, design approaches, and reliability considerations appropriate to each generic engine category will be briefly discussed. A scenario for a least risk strategy for the introduction of ceramics into airborne engines will be presented. Key issues in materials research and development will be identified. (Wassmann)
