Aircraft Arrester Barrier System Jamnagar

Aircraft Arrester Barrier system - The Aircraft Arrester Barrier system (AABS) is intended for emergency application to arrestthe aircraft. The AABS licated on the ends of the runway. These AABS are either net type of pendant type. In net type whole aircraft is envoloped by Net and in pendant type aircraft hook is engaged with pendent (metalic wire rope).
Arrester Barrier system is available in two variants:
(i) 0 For 6 to 20 ton class aircraft.
(ii) 0 For 20 to 40 ton class aircraft.
Stanchion system : The role is ro raise and lower the Net Assembly. It can be operated from relay hut(runway site) through main countrol panel (MCP) as well as from ATC through Remote control panel (RCP). In case of power failur it also can be opertaed manually at runway site. A rear limit switch is mounted on the base frame such that it limits the movement of the stanchion frame beyond the a specific position by cutting off the power supply to the geared break moter. The Nitrogen filled Shock Absorber is provided for smooth lowering of the stanchion. The leaf spring assembly and rubber shock pads are provided to ensure that Top mount assembly does not touch the ground.
Energy Absorber: There is a purchase tape wound on the tape drum of Energy Absorber and one end of purchase tape is connected to the net. When aircraft is arrested the purchase tape unwinds and tape drum rotaets. It generally absorb the Kinetic Energy of the aircraft.
Sheave Assembly: It guides the purchase tape during arrestment or retrieval and thus reduces the wear and tear of tape.
Tape Retrieval System: It is used to rewind the purchase tape electrically on tape drum.
