New Delhi:Anticipating an attack by the Desert Locusts, the government on Tuesday signed a contract with UK-based Micron to modify two for spraying atomised pesticide to arrest the Locust breeding.
Due to the Novel Coronavirus pandemic, the UK-based firm would be able to manufacture and supply the modification kit to IAF only from September, 2020 onwards for system integration and testing.
An unprecedented Locust attack had started manifesting from last week of May and was fast spreading practically across many states.
In view of the envisaged delay in provisioning of modification kits by M/s Micron, the tasked No 3 Base Repair Depot located at Chandigarh to undertake the challenging task of indigenously designing and developing an Airborne Locust Control System (ALCS) for Mi-17 helicopters, an IAF spokesperson said.
Using all indigenous components, the atomized airborne spraying of pesticide has been successfully achieved in air through a configuration of nozzles mounted both sides on external trusses of a Mi-17 helicopter.
The nozzles used for the purpose are a mix of commercially available nozzles as well as the nozzles developed by CSIO, Chandigarh.
The pesticide Malathion in appropriate concentration would be filled in the internal Auxiliary tank of 800 liters capacity fitted inside the helicopter and pumped into the nozzles by using an electrical pump as well as compressed air, achieving nearly 40 minutes of spaying duration in the infected zone covering an area of approximately 750 hectares in each mission.
A team of Test Pilots and Test Engineers of Aircraft and Systems Testing Establishment, Bangalore have successfully carried out ground and airborne trials of ALCS on a modified Mi-17 helicopter, he added.
The system is being offered for use with Malathion for employment in the locust control operation.Being an indigenously developed system, the ALCS would offer inherent advantages of in-house maintenance, future upgradeability, saving of foreign exchange and help in making the country Self Reliant in aviation related technology, he said.(UNI)
