"KAZAKH BASE FOR AVIATION PROTECTION OF FORESTS AND FOREST SERVICE"
Regular site version
The new helicopter had a larger cockpit and a larger take-off weight. The nose section of the fuselage was redesigned (taking into account the developments in EC 135), which reduced aerodynamic drag and improved visibility for the crew. The main rotor with an optimized profile and updated avionics became the distinctive features of the helicopter.
Model EC 145 - operated by a crew of 1-2 pilots and is designed to carry 9 passengers. Belongs to the class of light vehicles and weighs 1792 kg. Maximum takeoff weight 3585 kg, payload 1793 kg. The helicopter is equipped with a power plant consisting of two Tyrbomeca Arriel 1E2 turbo engines with a capacity of 738 hp. with., each. The maximum flight speed is 268 km / h. Flight range 680 km. The highest rise is 5240 km.
The EC 145, in contrast to the EC 135, has retained the classic single-screw design. Despite the original plans to equip the EC 145 with a tail rotor - a fenestron, the Eurocopter designers, after a series of experiments and analysis of the experience in the development and operation of the AS 365, abandoned this idea, considering the classic propeller safe enough for a helicopter with a takeoff weight of over 3.5 tons.
The maximum take-off weight in the process of modernization has increased markedly and reached 3585 kg or 3650 kg in the case of work with cargo on an external sling. The maximum carrying capacity has increased from 1590 kg (VK 117) to 1790 kg (EC 145). The diameters of the propellers remained the same as on the VK 117: the carrier - 11 m, the helmsman - 1.96 m, so the overall characteristic dimensions of the helicopter were kept the same. Only the overall height has increased by 10 cm due to the increase in chassis clearance.
When developing the EC 145 helicopter, the designers focused on increasing the carrying capacity and capacity of the helicopter, improving its flight performance and operational characteristics. The fuselage is almost completely new. While maintaining the overall layout, he received a much more streamlined shape. A nose section from an EC 135 helicopter was installed in front. It not only reduced harmful drag, but also significantly improved the pilot's view and comfort. The rear fuselage and cargo hatch flaps are also more streamlined. At the same time, the length of the fuselage increased by 20 cm.
In June 2001, the Eurocopter consortium demonstrated the EC 145 helicopter for the first time at an air show in Paris and collected the first export orders for the machine. Following the French government services, customers from other countries began to acquire a new car. The first were the Germans. The supply of EU helicopters to 145 customers began in April 2002. In total, the assembly shop in Donauworth has built 15 machines during this year. German helicopter builders delivered another 25 vehicles in 2003. In 2004, the consortium's press service announced the completion of the assembly of the fiftieth EU 145.
Thus, the deep modernization of the good old VK 117 carried out in 1997-2000 was crowned with success. It was replaced on the assembly line by a brand new EU 145. And although orders for the helicopter were still piecemeal, they were stable and encouraging. The revolution in the EU 145 helicopter market was made by the Americans.
After the EU 145 was certified in the USA in February 2002 and participated in the largest American helicopter exhibition Heli-Expo 2002, orders from the New World were poured on it. In September 2003, the first EU 145 went overseas. The main American customer for the EU 145 (UH-72A) was the Armed Forces. For the first time since World War I, the United States has adopted an aircraft of foreign design. This happened as a result of a series of failures that befell the Americans in the development of programs for light military helicopters.
Rescue Services welcomed the EC 145 with a great deal of appreciation for the improved performance and larger cabin. EC 145 has earned high praise in aviation divisions and emergency medical service companies. The helicopter cockpit can accommodate two stretchers, three medical specialists and all the necessary medical equipment, including those for intensive care.
Rear cargo doors allow - quickly and without problems - loading and unloading of patients and necessary medical equipment. Moreover, unloading of patients on a stretcher can be safely carried out with rotating main and tail rotor, which significantly speeds up the process of delivering the patient (wounded) to the operating table and increases the likelihood of his survival.
Good sound insulation of the cockpit, low vibration level and other features of the EC 145 provide doctors in flight with comfortable working conditions, and patients with relative comfort during the flight. The low noise level is also a very attractive feature of the EU 145 for security and law enforcement services, so the helicopter was purchased by the French Civil Security Administration (Securite Civile), the French gendarmerie, the Hesse police (land in Germany), etc.
As of the end of 2011, 87 operators from 32 countries operated more than 230 EU 145 helicopters.
The experience of using the EU 145 has been accumulated by the operators. In general, it is positive. One of the EU 145 even landed on the Mont Blanc peak (height 4810 m) in 2003. However, both European and American customers have received requests to increase the altitude performance of the helicopter, as well as flight performance when operating in hot climates.
In Kazavialesoohrana, the Eurocopter 145 helicopter is used to carry out forestry operations, as well as flights aimed at identifying and suppressing the facts of poaching, violations of hunting and fishing rules, carried out in conjunction with environmental authorities.
The main requirements for chainsaws used in the fight against forest fires are high reliability and low weight. The chainsaw "EFCO 136"is a portable, mechanical saw, the working part of which is a chain saw machine consisting of a chain closed in a ring, moving along a guide rail. The tire and chain are removable, so they are called a "headset". EFCO chainsaws are a product of the popular Italian concern EMAK Group, which appeared on the international market in 1992. The company is a manufacturer of high-quality gardening equipment, equipment and accessories. EFCO chainsaws in their quality and power characteristics are not much inferior to such well-known representatives as "Stihl" and "Husqvarna". A distinctive feature of all EFCO chainsaws is reliability and performance. Even in difficult working conditions and under high load, the tool motor provides high performance. The torque remains high even at low revs.
The EFCO 136 chainsaw weighs 4 kg. (without a headset) and belongs to the line of household tools. The two-stroke engine produces a rated power of 2.1 hp, the engine is started from the starting cable manually. A chain brake is provided, protecting the operator from vibration (vibration-damping handles). The tire is mounted up to 41 cm in size. The quick-release filter and the convenient cover easily fall into place. The amount of lubricating fluid to the headset is adjustable in the automatic mode. The controls are maximally placed on the handle.
The principle of operation of the unit is based on the effect of extinguishing with fine water under high pressure, while the water consumption is only 10-15 liters per minute.
The unit is equipped with a solid wetting agent supply system, thereby increasing the extinguishing efficiency. Mobility is provided by a lightweight and flexible high-pressure hose with a length of 50 m. With the help of the optional extension cables, the sleeve line can be extended by 50 or 75 m.
At a water consumption of UPVD of 10 l / min, a little more than 300 liters of water is enough to completely eliminate the edge of a fire on an area of 10 hectares.
The low weight and sufficient length of the high-pressure hose ensure high mobility when extinguishing multi-storey buildings. The device can be transported in cars, as well as permanently mounted on any truck or jeep.
All this makes the high-pressure fire-fighting system (UPVD) Ermak indispensable when equipping volunteer fire brigades and professional teams of municipalities, agricultural and forestry enterprises.

When extinguishing a grass-roots weak and medium intensity of burning forest fire (the flames on the edge of the fire 0,5 - 1,5 m.), forest fire with a gun-a gun moving at a distance of 3-5 meters along the edge of the fire, directing a jet of water under the base of the fire, which allows not only to extinguish the flames (to stop the fiery burning), but also to wash (to move on past the fire area) easy forest combustible materials, such as fallen leaves, pine needles, small twigs, etc., moisturize the remaining large forest materials (large branches, fallen trees, stumps, etc.) on the band width of 1-2 m of the perimeter of the fire. At the same time, the high pressure of the jet allows you to create not only a semi-cleared of forest combustible materials on the soil, but also to mineralize the soil (wash away the humus layer), which will completely localize the forest fire from combustible materials and eliminate the possibility of further spread of gorenje.
If necessary, the area passed by fire in the distance achieved by a water stream eliminates all visible heat sources.
Shipping UPWD "Ermak" to the place of work to extinguish a forest fire is usually on four-wheel vehicles, together with soft tanks (WFD) with a capacity of 100, 300, 600 and 1300 liters, which are filled with water at the exit to the fire or at work, if there are water sources, in the latter case, it is advisable to have a small forest a pump for filling water tanks soft. The ideal option is to deliver water to the work site in a tanker truck.
The transfer of the UPVD "Ermak" along the edge of a forest fire to extinguish the subsequent section, i.e., placement to a new position can be done manually by two workers.
The operation of the installation during extinguishing is provided by a group (fire brigade) of 6 people, of which:
1-one performs the duties of an engine driver;
2-the second provides extinguishing from the barrel-gun;
3-the third-provides the transfer of the pressure hose in the extinguishing zone and can replace the second one in the operation;
4 and 5 - the fourth and fifth-ensure the transfer of the RDV or other containers and filling them with water, as well as the transfer of the motor pump to a new position;
