HAL Dhruv is an Indian multi-purpose helicopter developed by Hindustan Aeronautics Limited in 1992.
The development of the multi-purpose HAL Dhruv helicopter began to be carried out by aircraft manufacturers from the Indian company Hindustan Aeronautics Limited in 1984. Initially, the designers spent a very long time preparing the project, trying to create a high-quality, inexpensive, and modern design that allows the helicopter to be used both in the civilian sphere of aviation, for which it was initially planned and in the military sphere. Thanks to the qualitative approach, the helicopter acquired a good aerodynamic component in its shape and therefore turned out to be very maneuverable and at the same time very high-speed, which provides an aircraft of this class with all the necessary flight performance.
The first flight of a HAL Dhruv model helicopter took place in 1992, and even though all flight and technical tests of the aircraft were successful, and the helicopter went into serial production, the helicopter was presented to the general public only in 2002.
Initially, the HAL Dhruv helicopter was very interested in the military command of the Indian Armed Forces, which ordered the development of four military versions of this aircraft from the aircraft manufacturer Hindustan Aeronautics Limited. In fact, in its military use, the HAL Dhruv helicopter can be used to perform a wide variety of tasks, including reconnaissance, electronic warfare, as well as transporting people and goods. Also, the HAL Dhruv helicopter can be positioned as an independent combat unit, in particular, the armament of such a version of the aircraft consists of:
- 8 anti-tank guided missiles;
- A set of unguided missiles;
- A set of missiles to combat air targets;
- 2 anti-submarine torpedoes;
- A set of anti-ship missiles;
- A set of deep-sea charges;
Onboard, the HAL Dhruv helicopter, depending on the modification used, can carry up to 16 people, including two crew members and 14 passengers (military personnel). If necessary, the aircraft can also carry onboard various cargoes on its board, the only condition for which is compliance with the dimensions and not exceeding the maximum take-off weight established by the technical regulations.
The power plant of the HAL Dhruv helicopter consists of two Turbomeca TM 333-2B2 gas turbine aircraft engines, each of which can develop its thrust of 1000 hp, however, Shakti aircraft engines can be used, developing a total thrust of 2800 hp. Depending on the aircraft engines used, the helicopter can reach speeds of up to 290 km \ h. At the same time, the maximum distance over which this aircraft can fly is 830 kilometers (range).
