Evaluation of a GN2-Powered, Mechanically Linked Dual Ejector System.
Abstract
This report contains a description and evaluation of a Naval Weapons Center designed dual ejector system that is cold gas (GN2) powered and uses hydraulic fluid as a media for ejection stroke extension. The report describes the construction of the system, tests performed and data obtained. The system has two identical ejector housing assemblies, each containing hydraulic fluid, a fluid displacing piston and telescoping pistons for ejection stroke. The GN2 pressure housing assembly has a piston power output. The fluid displacing pistons and the GN2 power piston are mechanically linked to provide positive dependency in movement. For parallel ejection, ejector extension is equal with the ejection force proportionally equilibrating the reacting forces encountered by the individual ejector assemblies. This proportional force distribution between ejector assemblies during parallel or pitch angle ejection requires no sensors or regulators. Using hydraulic fluid as a media for ejector extension allows controlling the amount of fluid available for extension in either ejector assembly, variations in stroke length of the two ejector assemblies telescoping pistons can create stores pitch anlge change or angular rate inducement. The ejection force is all on one of the two ejector assemblies for the angular rate ejector mode.
