In the present work, the dynamic characteristics of variable nozzles are described. Variable nozzles are used to enhance the effectiveness of aircraft engines at various altitudes. The dynamic characteristics of variable nozzle mechanism including flaps are analyzed by a multi-body dynamics analysis software, RecurDyn.

In the present work, a synchronization test system for variable nozzle is described. Variable nozzles are used to enhance the effectiveness of aircraft engines at various altitudes. The synchronization test system was developed to verify the dynamic characteristics and synchronization of variable nozzle mechanism including flaps. The system with a variable nozzle was analyzed, before its fabrication, by a multi-body dynamics analysis software RecurDyn. The newly developed test system is being used to show the synchronization capability of a variable nozzle system.
