Abstract

Aircraft Arrester Barrier Systems (AABS) are installed near the end of runways for the purpose of arresting combat aircraft due to over shooting of runway length during aborted take-off and emergency landings. Energy Absorbing System (EAS) is one of the important subsystems of AABS. The energy absorber consists of two velocity sensitive turbine type conventional rotary hydraulic energy absorbers. There is no control in conventional EAS on energy absorption during operation of an aircraft emergency arrestment. Also, if there is any problem with conventional EAS during operation complete system fails. For different types of aircrafts different EAS needed. To overcome this problem, we may use the combination of existing conventional EAS and eddy current absorbing system. An Eddy current energy absorbing system works on the principle of Eddy currents. In proposed EAS, braking torque is high and controllable. This will help in stopping any Aircraft (like light weight, heavy weight, etc). In this paper, the proposed eddy current EAS have designed and prototype has been implemented.
