Multi-purpose reconnaissance and attack helicopter Rah-
Multi-purpose reconnaissance and attack helicopter RAH-66 Comanche, Boeing and Sikorsky companies for exploration positions the most important goals and data about them on the command centers in real-time, anti-aircraft and armored ground targets, fire support of ground forces.
Helicopter created in the early 90s in accordance with the requirements of the competition program of the creation of reconnaissance and attack helicopter of the US Army under the program LHX (Light Helicopter Experimental), the main purpose of the helicopter is to conduct exploration and transmission of intelligence information in real-time search and defeat armored targets , conducting air combat support and combat and troop-transport helicopters. The first flight of a prototype helicopter took place January 4, 1996 goda.Osobennosti design. The design of the helicopter put the traditional scheme with maximum use of technology "stealth", with a five-blade main rotor and tail rotor type fenestron, two turbine engines and retractable tricycle landing gear in flight with a tail wheel. The helicopter has a fuselage of an aircraft type, made entirely of composite materials.
The configuration of the fuselage is somewhat unusual: most of the panels and fin are inclined relative to the vertical order of 30-45 °. This is due to the desire to provide reflected radar signals up and down and reduce the formation of flow of electromagnetic energy directed on the irradiated radar. To ensure the stealth helicopter, and to achieve a high maximum speed of the fuselage there are internal compartments for placing weapons. The closing of these compartments flaps on their inner surfaces have three assembly for the suspension arms. In a combat situation leaves open and take the form of conventional weapons to the pylons. Located in front of the fuselage cockpit and arrow-operator airborne weapons basically identical. Both crew members are located in armored, secure damaged chairs, which together with a specially designed floor cabs absorb most of the impact energy in a crash. Equipment.
ENCLOSURE equipped with modern appliances. The main place on the dashboard occupy two liquid crystal display: a monochrome display shows information from the systems review the forward hemisphere, and color - a three-dimensional digital maps with the representation of her tactical situation. In addition, information about the altitude, heading, speed and flight of the helicopter position relative to the horizon on the helmet-mounted display is displayed, allowing crew members to carry out their functions without looking down at the dashboard.
To accommodate the avionics in the fuselage includes a front compartment (under the seat of the arrow operator) and two compartments in the rear fuselage. The main component of the avionics is the main complex unit of equipment for combat missions, including two computers and high-speed data bus. With the main unit complex interact unified sighting-navigation and communication systems, automated targeting systems, life support system (protection against weapons of mass destruction) and the system of self-control, and troubleshooting of electronic systems. The presence of computers block the main complex of spare capacity will in the future be connected to the block of the new system, thus increasing the combat capabilities of the helicopter.
Power point. The power plant consists of two helicopter turboshaft gas turbine engines with free turbine LHTEC T800-LHT-801 with a capacity of 1430 hp, created especially for this helicopter. Motor control is carried out via a digital control system. To reduce the visibility of the helicopter in the infrared hot engine exhaust gases are mixed with cold ambient air and is discharged through two downward dvuhmetrovye panels mounted on each side of the tail boom. The capacity of the central fuel tank is L 1142. The helicopter has a five-blade rotor, the blades of which are made entirely of composite materials. The tail rotor is installed in the annular channel in Kiel T-tail.
Armament. Built helicopter armament consists of a 20 mm caliber trehstvolnoypushki GE Gatling, mounted on the turret at the bottom of the forward fuselage. Rate gun at ground targets is 750 rounds per minute, and in the air - 1500 rounds per minute. Ammunition - 320 rounds of ammunition. Suspended arms placed on six hardpoints on opening shutters (three suspension brackets on each side). If necessary, the suspension of additional fuel tanks or weapons by helicopter can be set small wings. Because of this on the external load can be set 8 anti-tank missiles "Hellfire", 8 containers of 32 or 16 unguided rockets missiles "Stinger" to fight against air targets. Under the detachable wings can be set as 2 fuel tank capacity of 1627 liters each, or 871.
