Helicopter Rope Suspension Technique
Helicopter Rope Suspension Technique (HRST) is a military term for techniques and methods of rappelling, fast roping, Special Patrol Insertion/Extraction (SPIE) and Jacob's Ladder operations. Helicopter Rope Suspension was developed as a means to insert and/or extract, by helicopter, ground forces (primarily reconnaissance teams) into or from rough terrain, urban areas or water. HRST is designed to be used in situations wherein aircraft landings are impractical due to terrain or tactical situation.

Helicopter SA 330 Puma 007
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most ...

Rappelling
Abseiling ( ; ), also known as rappelling ( ; ), is the controlled descent of a steep slope, such as a rock face, by moving down a rope. When abseiling the person descending controls their own movement down the rope, in contrast to lowering off in which the rope attached to the person descending is paid out by their belayer. This technique is used by climbers, mountaineers, cavers, canyoners, search and rescue and rope access technicians to descend cliffs or slopes when they are too steep and/or dangerous to descend without protection. Many climbers use this technique to protect established anchors from damage. Rope access technicians also use this as a method to access difficult-to-reach areas from above for various industrial applications like maintenance, construction, inspection and welding. To descend safely, abseilers use a variety of techniques to increase the friction on the rope to the point where it can be controlled comfortably. These techniques range f ...

Fast Roping
Fast-roping is a technique for descending a thick rope, allowing troops to deploy from a helicopter in places where the aircraft cannot touch down. The person holds onto the rope with gloved hands (with or without using their feet) and slides down it. Several people can slide down the same rope simultaneously, provided that there is a gap of about between them, so that each one has time to get out of the way when they reach the ground. Fast roping is quicker than abseiling (rappelling), although more dangerous, particularly if the person is carrying a heavy load, because the rope is not attached to them with a descender. The technique is particularly useful for naval infantry, who can use it to board ships at sea. History The technique was first developed by the UK with British rope manufacturer Marlow Ropes, and first used in combat during the Falklands War. The original rope was made of thick nylon that could be used in a manner akin to a fireman's pole. The special ropes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Special Patrol Insertion/Extraction
The Special Patrol Insertion/Extraction (SPIE) system was developed as a means to rapidly insert and/or extract a reconnaissance patrol from an area that does not permit a helicopter to land. SPIE has application for rough terrain as well as water inserts/extracts. It is an adaptation of the Vietnam War-era STABO rig. Generally, the SPIE rope is lowered into the pickup area from a hovering helicopter. Patrol personnel, each wearing a harness with an attached carabiner, hook up to a D-ring inserted in the SPIE rope. A second safety line is attached to a second D-ring located above the first. The helicopter lifts vertically from an extract zone until the rope and personnel are clear of obstructions, then proceeds in forward flight to a secure insert zone. The rope and personnel are treated as an external load and airspeeds, altitudes, and oscillations must be monitored.FMFM 7-40 Helicopter Rope Suspension Training (HRST) Operations The United States Coast Guard uses a simi ...

Fulton Surface-to-air Recovery System
The Fulton surface-to-air recovery system (STARS) is a system used by the Central Intelligence Agency (CIA), United States Air Force and United States Navy for retrieving persons on the ground using aircraft such as the MC-130E Combat Talon I and Boeing B-17. It involves using an overall-type harness and a self-inflating balloon with an attached lift line. An MC-130E engages the line with its V-shaped yoke and the person is reeled on board. Red flags on the lift line guide the pilot during daylight recoveries; lights on the lift line are used for night recoveries. Recovery kits were designed for one and two-man retrievals. This system was developed by inventor Robert Edison Fulton, Jr., for the Central Intelligence Agency in the early 1950s. It was an evolution from a similar system that was used during World War II by American and British forces to retrieve both personnel and downed assault gliders following airborne operations. The earlier system did not use a balloon, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STABO
The STABO (STA''bilized'' BO''dy'') extraction harness was a device which allowed military personnel to be rescued (by helicopter) from field locations which prevented the conventional landing and boarding of a helicopter. It was designed and developed by U.S. Army Special Forces personnel stationed in Vietnam during the Vietnam War, and became a widely used and highly successful extraction device employed during the Vietnam War. History Sergeant First Class Clifford L. Roberts, U.S. Army, Special Forces, drew up the first design on a napkin, after a wounded Special Forces Soldier fell out of a McGuire extraction rig, during a combat extraction mission. SFC Roberts used the unit's parachute loft, and made the first prototype on the sewing machines used to service and repair parachutes. He was then sent to present the design. The design was approved and 500 rigs were ordered. SFC Roberts was awarded a Bronze Star for the design.According to 'U.S. Army Uniform of the Vietnam W ...
