Reviving the Reliability of HAL's ALH Dhruv
Around 300 ALHs { Advanced Light Helicopter } of various varieties, including the Mk1, Mk2, Mk3, and Mk4, also known as the Rudra Weapon System Integrated, are flying with the three forces and the Coast Guard. The Army operates around 145 indigenous ALH, 75 of which are Rudra, with another 25 ALH Mk-III on order and due to be inducted over the next two years. The Air Force has around 70 ALH in service, the Navy has 18, and the Coast Guard has 20 ALH.
The ALH is a critical fulcrum for the services, including the Army, Navy, and Air Force. It is a utility helicopter that was designed in 1983 and is utilised across the services for a variety of duties, including personnel and material transport.
Following three separate accidents of ALH Dhruv in quick succession , Bengaluru-based Hindustan Aeronautics Limited has decided to replace a key component of the Dhruv Advanced Lightweight Helicopter in order to improve the fatigue tolerance of the made-in-India chopper, which serves as the rotary-wing mainstay for the Indian armed forces.
According to sources, the state-owned aviation will replace an aluminum-made control rod in the gearbox with a much tougher and corrosion-resistant material. This improves both the copter's fatigue tolerance and the pilots' control of the aircraft.
Insiders said the state-owned aviation will replace an aluminum-made control rod in the gearbox with a much tougher material and corrosion resistance . This increases the copter's fatigue tolerance as well as they pilots' control of the aircraft.
HAL officials said that the ALH had an excellent safety record, having flown more than 3,75,000 hours in the last two decades, and that metallurgical improvements to the gearbox's control rod is being carried out to improve the aircraft's performance.
The mean time for helicopter checks, which was originally 600 hours, has been reduced to 300 hours, and it has been learned that it has been further reduced to between 100 and 150 hours of flying.
Function of Control Rod in Helicopter Gear Box : Explained
The control rod in a helicopter gearbox is a mechanical linkage that transmits the pilot's control inputs to the main rotor and tail rotor systems. The control rod is typically made of a strong, lightweight material such as aluminum or titanium. It is connected to the pilot's controls in the cockpit and to the main rotor and tail rotor gearboxes. When the pilot moves the controls, the control rod moves, which in turn causes the main rotor and tail rotor to change pitch. This change in pitch causes the helicopter to move in the desired direction.
The control rod is a critical component of the helicopter's flight control system. It must be strong enough to withstand the forces generated by the main rotor and tail rotor, and it must be able to transmit the pilot's control inputs accurately. A malfunction of the control rod can result in a loss of control of the helicopter, which can be a fatal accident.
Here are the specific functions of the control rod in a helicopter gearbox:
-
Transmits the pilot's control inputs to the main rotor and tail rotor systems.
-
Allows the pilot to control the pitch of the main rotor and tail rotor.
-
Enables the pilot to move the helicopter in the desired direction.
-
Is a critical component of the helicopter's flight control system.
Here are some of the common problems that can occur with the control rod in a helicopter gearbox:
-
Bending or breaking of the control rod.
-
Corrosion or wear of the control rod.
-
Binding or jamming of the control rod.
-
Looseness or misalignment of the control rod.
-
Damage to the control rod's bearings or bushings.
These problems can lead to a loss of control of the helicopter, which can be a fatal accident. It is important to have the helicopter's control rod inspected and repaired regularly by a qualified technician to prevent these problems from occurring.

Donald Trump sends Diwali greetings, condemns attacks on Hindus in Bangladesh
Washington, Oct 31: Sending Diwali greetings, former president Donald Trump, who is the Republican presidential candidate, on Thursday condemned the attack on Hindus in Bangladesh, vowed to strengthen ties with India and described Prime Minister Narendra Modi as his good friend.
Bangladesh, he said, remains in a total state of chaos and alleged that his Democratic rival Vice President Kamala Harris and her boss President Joe Biden have ignored Hindus across the world and in America.
“I strongly condemn the barbaric violence against Hindus, Christians, and other minorities who are getting attacked and looted by mobs in Bangladesh, which remains in a total state of chaos,” Trump said in a post on Truth Social.
This is for the first time that Trump has spoken on the issue of Bangladesh. Hundreds of Hindus were killed in July-August in Bangladesh when a students’ agitation turned into massive protests leading to then prime minister Sheikh Hasina to flee the country on August 5.
“It would have never happened on my watch. Kamala and Joe have ignored Hindus across the world and in America. They have been a disaster from Israel to Ukraine to our own Southern Border, but we will Make America Strong Again and bring back Peace through Strength,” he said.
“We will also protect Hindu Americans against the anti-religion agenda of the radical left. We will fight for your freedom. Under my administration, we will also strengthen our great partnership with India and my good friend, Prime Minister Modi,” Trump said.
“Kamala Harris will destroy your small businesses with more regulations and higher taxes. By contrast, I cut taxes, cut regulations, unleashed American energy, and built the greatest economy in history. We will do it again, bigger and better than ever before and we will Make America Great Again,” he said.
“Also, Happy Diwali to All. I hope the Festival of Lights leads to the Victory of Good over Evil,” said the former president, who is in a close fight with Harris for the November 5 presidential elections.
