Thinking about an aircraft, the first thing to strike is the scenic view from the plane, comfort , and the easy but fast rushing through the air without any bumps, the fascinating buzzing sound, the soothing service and the beauty of nature.
This was one merry part of an aircraft system; let us take a look on one of the segments of the other side of the system say an aircraft arrestor system.
Wondering what an aircraft arrestor system does?
While emergency landings or while rejected take – offs , we make use of an Aircraft barrier/arrestor system which is installed at the end of the runway to stop the forward movement of an aircraft overshooting the runway so as to cause minimal damage to the aircraft or contusion to the crew.
When in motion aircraft develops an emergency, the aircrew has to decide if they need to use the arresting system. If needed, the pilot deploys the aircraft’s hook, and lands the plane at least 1,000 feet from the arresting system.
The hook drags on the surface of the runway until it comes in contact with the 1.25-inch steel cable. Once the aircraft’s hook captures the cable, the cable rips the nylon cords, holding it flat on the runway, and unravels its attached nylon tapes from storage reels.
As the tapes are unraveled, the reels turn a hydraulic pump that applies pressure to a set of modified brakes.
It is these brakes that bring the aircraft to a stop, small pieces of nylon rope are used to hold the cable flat on the runway, the aircraft arresting system is important because it is the only safe way of stopping an aircraft with only a minimal amount of damage while preventing the loss of its crew.
Each time the system is used the nylon tape must be inspected and rolled back onto its storage reels. The cable is then returned to its home at the start of the runway and tied down with nylon rope.
Arrestor barrier system is therefore essential. The barrier is lifted with the help of a system on the command received by remote control.
The aircraft arrestor system remains in open ground all the time, since it is used on runways. It is damaged by rodents who by nature chew and cut materials as they need to sharpen their continuous growing two pairs of incisors and hence the nylon tapes in open fields are prone to these rodent attacks. The rodents consume more than 50% of the nylon belt without any anti-rodent additive.
This is a serious issue which needs to be noticed and addressed immediately to provide better protection to the arrestor system indirectly benefiting the aircraft.
Rodents are mammals who are intelligent, social and can gnaw all time. They are attracted to the polymers due to their aromatic odour,attractive colour and smooth texture of the polymeric product. They have left their imprints on essential sectors such as Agriculture, Railways, Defence, Telecommunications, Gas Sector, Heritages etc.
They chew onto to the polymeric, plastic substances passing through every possible gap.
At present no measures have been taken in hampering the movement of these sneaky rodents in the aircraft arrestor system.
Application of conventional methods like rodenticides kills the target as well as the non-target species. They have high release mechanism which can leach out and pollute the air, water and soil. They pose a serious effect on human health as well.
These factors have led to the search of a non- carcinogenic, non-hazardous, non- mutagenic product for protection against the effect of these rodents.
Such a product is manufactured in India by CTech Corporation. Combirepel™ is an extremely low toxicity, non-carcinogenic and non-mutagenic, non- hazardous, non- dangerous and environmentally safe animal anti rodent aversive. CombirepelTM is consumed globally for myriad applications. It is a product resulting from smart technology and green chemistry.
CombirepelTMcan be incorporated in the nylon belt which would keep the rodent away and prevents the chewing of threads and keep the area rodent free.
CombirepelTMdoes not kill the rodents it just keeps them away by making use of sensory mechanisms. It is non-toxic to rodent as well humans.
CombirepelTM is compatible with all kinds of thermoplastic and thermosetting polymers such as PE, XLPE, PP, PVC, polyesters, epoxies and paints: both water and oil based. Combirepel™ is available in the form of solid masterbatch, liquid concentrate and lacquer.
