HAL Chetak is an Indian military multi-purpose helicopter developed in 1992 by Hindustan Aeronautics Limited.
Indian aircraft manufacturers from Hindustan Aeronautics Limited began designing the HAL Chetak model aircraft at the end of the 80s of the last century. The new aircraft project was supposed to receive a wide and multi-purpose purpose, however, the helicopter itself was positioned exclusively as a military aircraft, and was practically not used in the civilian sphere.
As a basic principle, Indian aircraft developers when designing the HAL Chetak helicopter used the model of the French aircraft Aerospatiale SA-316 Alouette III, which could not gain due popularity in the territory of European countries, as it had several shortcomings. Nevertheless, Indian engineers carefully redesigned the aircraft design, improving its aerodynamic performance, improving operational characteristics and technical part, which in turn led to very good results – the HAL Chetak model helicopter manufactured since 1992 continues to be actively used by the armed forces of India and until today.
The first flight of the HAL Chetak helicopter took place in 1992, and since all test tests were very successful, the project was put into serial production the same year.
The HAL Chetak helicopter can be used as a vehicle for transporting small groups of military personnel, as a patrol and observation vehicle, and as a light transport helicopter capable of carrying cargo weighing up to 970 kilograms on board.
Onboard, a helicopter model HAL Chetak can accommodate up to 5 people, including a crew consisting of two pilots and three military personnel. Even though this aircraft cannot be operated as an independent combat unit. The aircraft has a fairly high demand in the armed forces of India, where according to 2012 there were 18 aircraft of this model.
The HAL Chetak multi-purpose aircraft is equipped with a gas turbine-type propulsion system consisting of one Turbomeca Artouste IIIB aircraft engine capable of developing a 570 hp thrust. With the relative ease of construction of the helicopter, the use of a sufficiently powerful propulsion system allows the aircraft to accelerate to a cruising speed of 185 km \ h., With overcoming distances at distances of 600 kilometers.
Today, the production of HAL Chetak model helicopters is officially discontinued.
