Hindustan Aeronautics Limited (HAL), the Indian state-owned aerospace and defense company, has announced that it will replace the aluminium control rods in its Advanced Light Helicopters (ALH) with steel ones. This move is aimed at improving the safety and reliability of the helicopters, which are widely used by the Indian armed forces and civilian operators.
The ALH is a multi-role helicopter that can be used for a variety of missions, including transport, reconnaissance, search and rescue, and medical evacuation. It is powered by two engines and can carry up to 14 passengers or 2,500 kg of cargo. The helicopter has been in service since the 1990s and has undergone several upgrades over the years.
One of the key components of the ALH is its control system, which includes the control rods that connect the cockpit controls to the various mechanical systems that operate the helicopter’s rotor blades, engines, and other systems. These control rods are critical for ensuring that the helicopter responds correctly to pilot inputs and operates safely and reliably.
Until now, HAL has used aluminium control rods in its ALHs. However, the company has now decided to switch to steel control rods, which are stronger and more durable than aluminium ones. Steel control rods are also less prone to corrosion and fatigue, which can lead to failures and accidents.
According to HAL, the decision to switch to steel control rods was based on extensive testing and analysis of the ALH’s control system. The company conducted a series of tests on both aluminium and steel control rods to determine their strength, durability, and resistance to corrosion and fatigue. Based on these tests, HAL concluded that steel control rods were superior to aluminium ones in terms of safety and reliability.
The switch to steel control rods is expected to improve the overall performance of the ALH and enhance its safety and reliability. It will also reduce maintenance costs and increase the lifespan of the helicopter. HAL has already started retrofitting its existing ALHs with steel control rods and will use them in all future production of the helicopter.
The move to steel control rods is just one of several upgrades that HAL has made to the ALH in recent years. The company has also introduced new avionics, engines, and other systems to improve the helicopter’s performance and capabilities. These upgrades have helped to keep the ALH competitive in the global market and ensure that it remains a key asset for the Indian armed forces and civilian operators.
In conclusion, the decision by HAL to replace aluminium control rods with steel ones in its ALHs is a significant step towards improving the safety and reliability of these helicopters. The move is based on extensive testing and analysis and is expected to enhance the overall performance of the ALH. With this upgrade, HAL has once again demonstrated its commitment to providing world-class aerospace and defense solutions to its customers.
