Experimental investigation of infrared signal characteristics in a micro-turbojet engine

open access: diamondThe 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
