Sikorsky HH-60 Pave Hawk
Helicopter Sikorsky HH-60 Pave Hawk was designed by American designers as a multipurpose unit and was adopted by the US Air Force. Before the designers had put the main task to develop machines to replace older models Bell UH-1.
History of helicopters Sikorsky HH-60 Pave Hawk
Draft helicopter Sikorsky HH-60 Pave Hawk started to be developed by American design engineers at the end of 70-ies of the last century. At the same time, aircraft manufacturers have tried to create on the basis of the existing models of other multi-purpose aircraft that can be used not only for carrying out special operations, but in fact, become a spacious transport and cargo aircraft.
External differences between the current model helicopters and helicopter of the same series there is little, over the next several elements is not technically affect, flight performance, but substantially improve the capabilities of this aircraft.
Initially, the US Air Force had planned to order a helicopter for rescue operations and to replace the old machine type HH-3. But the customer could not afford phones originally proposed. Sikorsky helicopter company prepared designation HH-60E, but due to the complex structure and the price of the machine it was abandoned in 1984 year. Instead, it was proposed helicopter HH-60A, which eventually was adopted.
This machine first flew in winter 84 years. A feature of the first cars was that they were obtained by the conversion of already existing transport helicopters UH-60A. The main differences were equipping cars refuel without landing system and improvement of stabilization in the hover. In addition, the designers have equipped the product with additional fuel tanks, which are placed in the cargo bay. A more perfect was the cockpit, namely its equipment. For the first time the helicopter began service in 83 year, it is mainly used to carry out rescue operations.
In the future, the Air Force Command has decided once again to upgrade the machines, which are now designated as the HH-60G. This product has turned out much cheaper in operation and under construction. In this modification has been installed a more powerful radar of the "Bendix-King 1400S." There was Doppler installation through which it was possible to carry out several modes of operation, using the satellite. To protect the signal has been found the best equipment. Avionics system was self-destruct mode. For flights at night pilots using infrared system that was associated with the pilot's helmet. Apparatus of this type was completed by 55-Squadron US Air Force 87 year.
This helicopter is mainly used for the transportation of military sabotage groups with a small composition in an amount of up to four people. Nevertheless, the device has the ability to transport ten soldiers with full gear. On arms 55-Squadron had ten machines of this type, four of them were constantly on the alert. They can quickly get to any place in the world to perform tasks due to the fact that they could carry cargo plane P-5 «Galaxy." This efficiency has been demonstrated in 89, when these machines were in Ethiopia in just 14 hours after the order. As for combat missions, this unit is also used in the conflict in the Persian Gulf and Yugoslavia.
Often in the literature there is the designation MH-60, but this is not a complete machine, because it has infrared system for the review of the front of the hemisphere. Typically, it is used to train pilots. At this time, the most relevant and useful for the army is a modification of the HH-60K.
Design features multi-purpose helicopter Sikorsky HH-60 Pave Hawk
For an overview of the front hemisphere device installed AN / AAQ-16, designed for pilots with a special helmet displays. The entire complex is integrated into a single system using the interface MilStd 1553B. For studies of meteorological conditions on board there is a system Bendix. To navigate using Doppler equipment, inertial navigation system installed. To improve the survivability of the helicopter has a system of warning of enemy missiles start. There is an active defense as a discharged reflectors are also used flares. This machine has the ability to transport goods using an external suspension.

As for weapons, the machine-type Sikorsky HH-60 equipped with two machine guns M134 brands that have a standard gauge in 7,62 millimeter. Machine guns mounted on the turret near the sliding doors on both sides of the body. This weapon can be changed on a large caliber machine guns. In addition to guns, the machine is equipped with two blocks of 19 missiles. They were attached to the outside of the helicopter hanger. Instead, you can also set the containers with large-caliber guns.

The cabin of the helicopter has a sufficiently large size, which in turn allows you to carry on board both people and all sorts of goods. In addition, to date, this model of aircraft is one of the most effective for use on the battlefield as a medical air tools.
If necessary, in the helicopter Sikorsky HH-60 Pave Hawk can accommodate up to 16 people (including crew members 4 and 12 marksmen armed soldiers), which is quite a good indicator for this helicopter. In addition, the aircraft can be placed on an equivalent volume, but limited by weight 2640 kilos number of payload, which in turn is most actively used for the carriage of ammunition, weapons and other goods.

Despite the fairly large for this type of helicopter load capacity, it uses the average in its power power plant, consisting of two turboshaft aircraft engine model General Electric T700-GE-700 / 701C capacity of 1630 hp each, which, nevertheless, provides a very acceptable speed helicopter displacement component up to a maximum at its 360 km \ h., which is comparable with the current models only aircraft of this type. Depending on the used fuel tanks, helicopter Sikorsky HH-60 Pave Hawk can travel a distance of up to 818 kilometers, which is also satisfactory indicator.
