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

Planning and Control for Autonomous Landing of Quadrotor Unmanned Aerial Vehicles With Disturbances

Engineering Reports, Volume 8, Issue 9, September 2026.
This paper proposes a trajectory planning method for autonomous landing and designs a disturbance‐compensated nonlinear model predictive controller (NMPC) for environments under wind disturbances. An efficient trajectory planning method based on MINCO is proposed, which transforms the trajectory planning problem into an optimization problem.
