US special forces will receive a parachute that allows you to fly almost 50 kilometers

American special forces will have at their disposal a new model of the parachute. According to the information from the Army Times, this parachute will allow jumping from a height of about 7,3 thousands of meters, carrying loads weighing up to 204 kg and reaching a target located approximately 47 kilometers from the trooper's dropping point. With a certain preparation, you can jump from a height of thousands of meters into 10,6. According to published data, the novelty received the designation RA-1.

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.

Russian parachute system "Crossbow"

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.

    No need to look for a black cat in a dark room when she is not there. The military of the Russian Federation and the Pentagon, the developers were given the same tech. tasks, as a result of which almost identical objects were obtained, or do you think that the laws of aerodynamics in the Pentagon are different?

      As for the parachute, it's a paraglider. By the way, the paraglider is, in fact, very unfinished and "raw". Due to the fact that it can "add up", but it can be very easily avoided.

        I certainly am not keeping back. Do you know why waterfowl have a wet body surface? Because there is no resistance between the liquid layers. The flow distribution vector is such that there is no accumulation of ionization polarization on the outflow surface. And of course the submarine builders "know it" and do the opposite. What you say is abstraction and rhetoric. In mathematical language, everything is explainable. Only not in the language of integrals and differentials and the Stokes equation, but in the language of the knowledge that is still little known.
        We are now positioning, for example, without a cavitation screw and controlled principles of the process called supercavitation, and on those devices that abroad, for example, have the name of the "Barracuda" project, but the scientists-traditionalists really do not even want to enter into a dialogue.
        By the way, scales are needed in order to prevent the accumulation of email. magnetic potential so that there is no cavitation. A muscle wave is an interesting fantasy!

            Of course, the interrelation of laminar and turbulent outflows is in such an algorithmic dependence of the process change that cannot be described by the methods of modern mat. analysis. Nevertheless, it is possible to construct a comprehensive solution to the question of how the polarization is distributed on any surface of the outflow at any point of this object. In other words, the mathematical system should be built as dynamic in its transformation, equivalent to how the parameters of the change in the entire set of the process of body movement in the medium and changes in the medium itself on the outflow surface change. By simplicity, it is possible to give a well-grounded decision that it is precisely the "ionic" (well, there is no other word yet) polarization of the outflow surface of each flake or part of the body should accumulate only such a part of the potential difference distributed over its surface that provides the most efficient without cavitation outflow of the flow, relative outflow surfaces.

    Is there at least one parachutist among the participants in the discussion? Well, let it be with the initial landing experience of jumping on round canopies from a height of 800-1000 meters, with the AN-2 (Mi-8), with the forced deployment of the parachute or the delay in the deployment of up to 5 seconds on the device? My experience is a little wider, and concerns not only the parachute, but also the paraglider. There are many very naive comments. On one such - "On business, but how realistic is it to land loaded with 200kg of cargo?" - I will answer.

    "Carry a load weighing up to 204 kg" - here, apparently, the total weight of the paratrooper and the load is meant. So that we are talking about a man weighing under a hundred and his "backpack" of approximately the same weight. Landing with this cargo is real, because he is not loaded onto the paratrooper, but is suspended from the parachute system independently (separately) from him. Upon landing, the weight of the load does not affect the paratrooper's legs. The paratrooper only controls the entire parachute system, but this does not mean that all the loads acting in this system go through him.

    Much more difficult is the question of separation from the plane. A person must independently pull a hundred-kilogram load to the exit and separate from the plane. Well, a trained man will probably cope with the movement of one hundred kilograms to the exit. And the only way out is the tail ramp (through the side door, punching the air flow, it is impossible to separate with such a load). The paratrooper, as it were, falls off the ramp, and does not ferociously burst into the stream through the side door.

      It is worth talking about the complex of solutions associated with such flights and the very organization of the flight. In response, I note that there is a very big difference between the fact that the parachutist himself weighs 200 kg and the fact that the weight is unbalanced by one hundred kg. This is especially important in such unstable and changing flight conditions as on a paraglider. And then it is worthwhile to understand that an entertainment flight adjusted to entertainment tasks and flight in a combat situation are strikingly different complex conditions. Let me remind you once again that the paraglider is completely uncontrollable with all directed vectors of air flows. In addition, he himself loses his shape and is unstable in maintaining it. Therefore, combat flight systems must necessarily change their configuration depending on the flight conditions and dynamic flows of different strengths and vectors of the direction of impact. In a word, like birds. Of course there are developments, but there is no systemic development program. In general, such flights are not based on "wing theory"

    I will continue the "explanatory work" on the issues raised here a little later, but first of all, one must firmly understand that it is impossible to have fun with a parachute and a paraglider, because "to cut the air with your body is not to solve problems, you can put your head down not for ... the dog's" ... The parachutist (paraglider) is always a fighter, not a consumer of entertainment.
