Variations of the driptorch can be attached to off-road vehicles, such as tractors, to ignite a fire while driving slowly along the ignition line. Another variant of the driptorch is the helitorch , which is attached to a helicopter and is used to ignite fire from the air.
Helicopters with fly-by-wire systems allow a cyclic-style controller to be mounted to the side of the pilot seat. The cyclic is used to control the main rotor in order to change the helicopter's direction of movement. In a hover, the cyclic controls the movement of the helicopter forward, back, and laterally.
A wide variety of helicopters and fixed-wing aircraft are used for aerial firefighting. In 2003, it was reported that "The U.S. Forest Service and Bureau of Land Management own, lease, or contract for nearly 1,000 aircraft each fire season, with annual expenditures in excess of US$250 million in recent years".
However, the crash of a helicopter conducting aerial ignition on 19 April 1978 with the death of two forest officers and the pilot [43] profoundly shook the small "Fraternity of Foresters". But it led to better accident insurance for staff involved in air operations, the end of DAIDs and the wider adoption of the safer ping-pong ball aerial ...
In 1994, a fuel injection system with electronic ignition, and FADEC was added to the Exec 90, producing the Exec 162F. Unlike most U.S.-designed helicopters, the main rotor on the Exec 162F rotates clockwise, as seen from above. The Exec series was further developed into the RotorWay A600 Talon, which replaced the Exec in production. [2]
Today, on most modern aircraft the swashplate is above the transmission and the pushrods are visible outside the fuselage, but a few early designs, notably light helicopters built by Enstrom Helicopter, placed it underneath the transmission and enclosed the rotating pushrods inside the mainshaft. This reduces rotor hub drag since there are no ...
Lack of instructions to the crew and their failure to keep a lookout and communicate led two Japanese navy helicopters to collide during training, killing all eight people on board, a Japanese ...
Robinson Helicopter Tow Cart Connected to R22. R22’s are equipped with wheel mounts toward the rear of the skids, one on each side, for attachment of removable wheels. The wheels must be removed prior to flight. These brackets are slightly behind the helicopter center of gravity so when the wheels are installed, the helicopter sits nose low.
