Eight of past and future

According to preliminary estimates, in 2011 the enterprises of JSC "Helicopters of Russia" produced about 260 vehicles, of which about 70% are Mi-8/Mi-17 helicopters of various modifications.

His contribution to the statistics of purchases "eights" have made the United States. In the spring of 2011, the U.S. Congress approved the deal between the command of the Army and the Armed Forces of the United States of "Rosoboronexport" for delivery of 21 new military transport helicopter Mi-17V5 for onward transmission to the Afghan army. The contract provided for the supply of spare parts, ground support, and the provision of services in logistics. The deal was the first project in the sphere of military-technical cooperation between Russia and the United States. At the end of last year, the Russian delegation headed by the Deputy Director of the Federal Service for Military-Technical Cooperation Anatoly Punchukom visited Huntsville (Alabama, USA), where the ceremony was held the Russian side of the certificate of recognition by the Ministry of Defense procedures for assessing the airworthiness of military transport helicopters operating in the Russian Federation for military transport helicopters. The helicopter, which became the world’s legend is still in great demand in the global aviation market. In June 2011, the 50th anniversary of the day when the test pilot B.Zemskov first raised to the sky-engine helicopter experienced V-8, which later became well-known to all the Mi-8.

Over the past five decades, the Mil Moscow Helicopter Plant. Mil (Mil Moscow Helicopter Plant) spent upgrading, creating new versions of "eight." Machines are equipped with new systems and complexes. Total has developed more than 200 models of legendary vehicles. They are produced in single units and large series. Over the years, the aircraft plants in Kazan and Ulan-Ude built more than 12 thousand "eights". The number of flight tasks performed on the Mi-8 is unlikely anyone will be able to accurately count. Operators in more than 100 countries around the world believe the car of one of the most reliable, undemanding and easy to use. SAFETY FIRST According to ICAO, in the world in all types of aviation because of erroneous actions aircrew is 60-80% aviaproicshestvy. In 2009, the International Helicopter Industry Exhibition «HeliRussia» conference "Safety and Security of Russian helicopters." It reported on "The human factor in accidents," made distinguished test pilot and Hero of the Soviet Union Gurgen Karapetyan. He read the statistics. In the 1985-2009 years, 72.8% of accidents associated with the operation of helicopters Mi-8/Mi-17 been due to crew errors. Karapetyan made no secret of the fact what factors are due to errors in the flight crew piloting technique and operation of aviation facilities. They have been listed. At least one of them was detected in almost any air crash: deficiencies in the training for the flight crew, ill-prepared to act in difficult situations; revaluation of its flight crew level of preparedness, insufficient interaction or omissions of crew members in flight; ignorance, non-compliance and violation of the rules of safety , airworthiness requirements and operational and technical documentation. The conference also examined in great detail and named other causes of accidents. At this event, manufacturers and operators talked about the need to take urgent measures to improve the quality of training of flight personnel helicopter aviation. It was suggested to create a specialized structure on the basis of flight test center STC "Helicopters of Russia" as a branch of the Center training of pilots and maintenance personnel LII. Gromov. Its purpose — practical preparation for action in emergency situations in flight crews of civil helicopters, state, and experimental aircraft to act in emergency situations in flight. On the Mil Moscow Helicopter Plant, work is continuing to improve, "eight". "Mil" in their work take into account trends in global aviation safety. Not so long ago, they tested the hardware anti-collision with the ground GPWS two companies: "Transas" and VNIIRA "Navigator." Such equipment is recommended to be installed on helicopters Mi-8. Concerned about safety issues and the Interstate Aviation Committee (IAC). It is based on the results of investigation of three accidents recommended work out and implement constructive solutions to protect the cargo cabin of the Mi-8 from non-localized destruction of free turbine engines. The pilots are very carefully examined the materials of final reports MAK Commission on these cases. Documented evidence that the factors act in which helicopters fall into the mode of a vortex ring or a spontaneous counter-clockwise rotation. In the vast majority of these cases develops into a catastrophic situation, if the crew does not have the necessary theoretical training. Training flights to test the skills of dealing with such situations are not provided because of their great danger. IAC offers a way to design changes. Strengthening the ceiling of the cabin will require alignment of the helicopter count, and actually change the design to completely redo the fuselage. The process is not only time consuming but also financially disadvantageous. This can lead to a halt the Mi-8T or irrational costs for the operators. According to a distinguished test pilot Sergei Barkov (MHF im.Milya) in our country are killed on the roads each year tens of thousands of people. A huge number of vehicles after a car accident like crumpled tin and burns to the ground. No one is recommended not to prohibit the operation of vehicles, until they are equipped with an automated, efficient sprinkler system, and their body will not have sufficient strength to prevent crease retention. When a person violates the rules of the road or the vehicle operates properly, no one expressed complaints about the car designers. On the engine TV2-117 is a "safety cushion" — a system of protection of turbine rotor (SZTV), which switches off the engine in case of promotion of the free turbine rotor speed up to 131 ≥ 3% (126 ≥ 3% of turnover HB). However, it is not a panacea for crew errors, unable to properly assess the weather conditions during approach and calculate the maximum takeoff weight, taking into account the negative factors. They lead to the so-called spontaneous rotation of the helicopter left on take-off or landing. In addition, in all the cases mentioned in the course of carrying out landing took place at a critical moment, followed by the destruction of a helicopter on the earth’s surface. Because of this, TV2-117 engines could not work SZTV. Given such a catastrophic scenario in helicopter pilots have a rule to a certain extent duplicate SZTV and minimize negative impacts. When you perform an emergency landing, almost in front of the helicopter touching the earth’s surface, board technician team, the aircraft commander closes the stop-valves, thereby turn off the engine through the fuel in them, but also turns off the helicopter. This helps prevent the destruction of the engine, where the blades may break and cause a fire. That is why in this case the helicopter is considered more optimal way to comply with the laws of aviation, when excluded to bring the situation catastrophic. THE FUTURE IS CREATED TODAY Nowadays designers head developer helicopter "Mi" brand is actively implementing a program of deep modernization of Mi-8. Work on a new program with the symbol "Mi-171M" began in 2009. When the car will receive certificati
on designation Mi-171A2. The helicopter is planned to install the VK-2500 engines. Expected widespread use of components and structural elements of composite materials. First of all, it’s rotor blades, similar to the blades of the Mi-38. It is interesting to note that on the Mi-8 helicopter, which was used as a flying laboratory "break-in" and tail rotor to be installed on the Mi-38, was registered an increase rotor thrust of about 800 kgs. The maximum range of 1200 km, but will remain the same weight of cargo. Created two versions of the rear cargo compartment: with wings and a ramp. The customer can then decide what is better for him. The car is equip with a new set of equipment — the so-called glass cockpit. As a result, the crew consists of two pilots. However, to preserve jobs for the third member of the crew — the operator, supervisor or examiner. With this planned reconfiguration of the cockpit in terms of ergonomics: the arrangement of controls, equipment and systems to be accessible and convenient for both pilots. Under the option plan to install a weather radar, observation stations, night vision systems. According to recent reports the first prototype of a new fuselage of the helicopter Mi-171A2 (article 171A-01) has already been constructed and handed over to the developer. At present, the designers say about the future of the helicopter only as a civilian vehicle. But there is no doubt that if the new helicopter interested in the military, it will be refined on the basis of their claims. The plans for a new modification of the Mi-171A2, and modernization of machines operated Mi-8/17, according to experts, will operate the "eight" for at least another 20-30 years.
