Helicopter AH-1G Huey Cobra. Description. Characteristics. A photo.
The experience of war in Korea, opened a huge potential in military helicopters. One aspect of such use of helicopters was an opportunity to use them as stormtroopers. The Americans have been an option UH-1, which is installed on a machine-gun armament and NAR. However, the designers and the military to understand that the army is needed not only an armed commando, but also an attack helicopter.
Creating a helicopter.
In the early 60-x number of aviation companies in the US began to develop the combat rotorcraft. Most impressed by the military YAH-56 "Cheyenne" firm "Lockheed", but because of the high cost and complexity of the design of its serial production was postponed indefinitely. There was a war in Vietnam, the US command decided not to play for time, and in December 1964, the company commissioned the "Bell" to develop an attack helicopter as soon as possible. The order was made in September of the same year began flight tests UH-1H, the helicopter was adopted under the designation AH-1G «Hugh Cobra".
The components of the helicopter.
In the development of the helicopter designers went the shortest way: "Cobra" is a deep modernization of the UH-1, coupled with some features of experienced helicopter design model 207 "Sioux Scout." Location of the engine, tail boom, transmission and rotor (with minor modifications) is completely borrowed from the UH-1. At the same time it becomes much narrower fuselage, which contributed to an increase in speed.
Significant changes were the front part. cockpit (rear) and the arrow (front) are arranged in tandem. lamp design ensures good visibility. After some doubts on the helicopter decided to leave ski gear, because thanks to the fuselage structure he had desired speed. Successful was the location of weapons. Sextuple M134 «Minigun" was placed in the turret under the cabin, and on the sides of the fuselage had four pylons on which it was possible to install additional machine guns, 20-mm guns, grenade launchers, ATGM and NAR.

In August, the first 1967 "Cobra" were taken in Vietnam. Their combat use started in October and was very productive. This recognition in the US military, they have received during the offensive Vietcong in January 1968 The main objectives of these helicopters was to destroy the enemy's manpower, combat boats, bunkers and light equipment.
"Cobra" is also engaged in accompaniment landing UH-1. With more firepower, they destroy air defenses in case of detection. Faced with the heavy armor of Soviet-made, American pilots felt the lack of effectiveness of the NAR and air guns. To remedy the situation helicopters equipped with ATGM "TOW".
Unpleasant surprise from the Viet Cong began Soviet MANPADS "Strela". Among the "Cobras", to distinguish good survivability, there were losses. To eliminate this threat, the designers have changed the design of the hot gas system. Now the bent pipe takes them up into the rotor strontium, where the strong airflow immediately dispelled them.

The maximum takeoff weight 4536 kg. Maximum speed 315 km / h. The maximum rate of climb 8,22 m / s. Static ceiling 3720 m.
