US special forces will receive a parachute that allows you to fly almost 50 kilometers
Due to the fact that the parachute system allows you to carry cargo weighing up to two centners, a soldier can jump in full combat gear, including body armor. According to the Americans, their new parachute in its basic performance characteristics significantly exceeds the parachute of the previous model, which wore the designation MC-4, in no way inferior to it in reliability. According to the ITAR-TASS news agency, the new model of the American parachute will have to arrive in the troops already in the 3 quarter of the 2014 year. It is planned that they will be equipped with only small units of American special forces. The RA-1 parachute, which has enviable maneuverability, is not intended for a mass landing of paratroops, since maneuverability leads to the possibility of parachutists colliding in the air.
Unlike most conventional parachutes, the RA-1 is equipped with a seat - this is to ensure that the legs of the Special Forces do not get numb, and at the time of landing he was ready to fight. According to the publications that have appeared, the American army will have to equip its paratroopers with additional equipment: insulated clothing, oxygen masks, which are designed for a longer period of flight, and an improved navigation system. The parachute system officially submitted by the Americans is called the Military Free Fall Advanced Ram-Air Parachute System (the military system of the advanced paraglider for free-fall jumping).

As you might guess, the American parachute is made of the "wing" type. So, if a parachute in the shape of a dome can only fly down, in the shape of a dome with slots - down and forward, then the wing cannot fly forward. Such parachutes create lift force only due to the fact that they move with a certain horizontal speed. Due to the flight speed, it is possible to create a significant pressure difference on the lower and upper wing shells. This allows a much smaller area of the wing than a standard round parachute to create a similar lift. The shape of the wing is maintained due to the speed of decline. Horizontally, such parachutes can fly at a speed of 32 km / h, and go down at a speed of 0-6 km / h.
The wing is controlled using two control lines, as well as a dome. If you pull the left line, the wing turns to the right and vice versa. If the paratrooper pulls immediately behind both lines, there is a decrease in horizontal flight speed. If you pull the lines strongly enough, the speed will decrease to such an extent that the wing will practically cease to create lift force and at the same time will begin to lose its shape. This will force him to “part” with the lift, which will lead to the stalling effect - the wing will simply dive sharply down. Also, the wing has another feature. Before such a parachute goes to stall, its speed, both vertical and horizontal, will decrease by a very short time to almost 0 km / h. If the paratrooper lets go of the control lines, then after some time the wing will restore its original shape, and it will be able to continue its flight with the speed characteristic of the parachute.
The closest Russian analogue of the new American parachute is the famous Arbalet parachute system. Unfortunately, in the open access there is no information about how far the Russian paratrooper could fly on a parachute system “Arbalet-2”. At the same time, the “Crossbow-2” system ensures safe making of jumps with the flight mass of a paratrooper with all special equipment up to 150 kg. The parachute can be used in the temperature range from -35 to + 35 degrees Celsius at the speed of flight of the aircraft at the time of landing to 350 km / h. This parachute system has passed the entire cycle of state tests in the flight test center of the Russian Ministry of Defense and is currently in operation.
Until the middle of 2015, Russian paratroopers should receive 400 parachute systems "Crossbow-2". This parachute system is designed for landing special groups, paratroopers-specialists and parachutists-rescuers with a full range of necessary equipment and weapons, as well as performing training jumps from aircraft such as: IL-76, An-12, An-26 and An- 2, as well as Mi-8 type helicopters, which have the necessary equipment to drop personnel.
