Model Test of a Turbo-Type Energy Absorber for Aircraft Carrier Arresting Gear

摘要

Increasing energy absorption requirements are being placed on present day aircraft carrier arresting gear engines. Hydraulic ram type engines have reached the upper limit of their development due to weight and space limitations. A turbo-type energy absorber has been proposed as an alternative. The Naval Air Engineering Center is currently developing such a machine. Theoretical analyses have determined the absorber to be practical. This study involves the testing of a flow model of that absorber with the objective to verify loss coefficients and check for flow separation in the passages. (Modified author abstract)
