Micro turbojet engines are one of the most powerful and compact propulsion systems for various unmanned aerial vehicles and become more widely used for aerial vehicles including manned ones due to its low cost and simple structure features. This paper introduces the manufacturers and the major specification, performance parameters of micro turbojet engines ranging up to 1,000N thrust level, and research trends of performance improvement of micro turbojet engines. For that, the investigation has been conducted for 104 micro turbojet engines by 24 manufacturers. The investigations showed that the weight and dimensional features, operating conditions have a clear tendency with respect to thrust level, which would be a guideline for designers and developers of micro turbojet engines. However specific thrust and fuel consumption have scattered values, which means those are strongly dependent on the performance and efficiency of the engine components. Therefore current research trends on micro turbojet engines have focused on performance evaluation and improvement of the components, such as compressor and combustor. Korea Aerospace Research Institute has conducted component design, analysis and test evaluation of the micro turbojet engines and continuing the effort to develop indigenous engine models.
