Experimental investigation of infrared signal characteristics in a micro-turbojet engine
The Aeronautical Journal, 2019 ABSTRACTInfrared signal measurements from a micro-turbojet engine are conducted to understand the characteristics of the engine performance and the infrared signal by varying the exhaust nozzle configuration. A cone type nozzle and five rectangle type nozzles whose aspect ratios vary from one to five are used for this experimental work. As a result, it

Journal of Physics: Conference Series, 2021 Abstract This paper presents the results of an aerodynamic analysis of a small-scaled transonic centrifugal compressor for micro turbojet engine (TJE) applications. The analysis was conducted using a CFD model validated by experimental data collected for the gaged JetCat P200-RX micro-TJE.

Flow physics in a micro turbojet engine inter-shaft fuel supply system [PDF]
Physics of FluidsInter-shaft fuel supply systems (ISFSSs) consisting of a shaft annulus and a fuel slinger are usually used in micro turbojet engines to pump the fuel to the combustor, aiming at reducing engine's size and weight. Differing from the configuration with stationary fuel pipework, the fast-rotating shaft in the annulus would induce significant drag ...

Study on micro-turbojet engine with high thrust-to-weight ratio
Theoretical and Natural Science, 2023 Micro-turbojet engine refers to a closed cycle gas turbine engine with thrust below 500kg and power below 100kW. The performance indicators of domestic products are relatively low, and the main problems of domestic products are low thrust-to-weight ratio, poor reliability, and low heat resistance.
