AD-2000 troop parachute
The AD-2000 troop parachute is intended for special duties troops, the tasks of which include stealthy flights at far distances. Thus the parachute was designed with two ramair canopies in back to back layout which, thanks to high glide ratio allow cruising at distances of up to 30 km, while high controllability ensures free selection of landing spot.
Tasks of the paratrooper require carrying of weapons and additional equipment container, while high altitude jumps - also of an oxygen system and protective clothing. That is why the AD-2000 parachute is delivered as a complete set, including a container which serves as a transport bag, and the harness with wide adjustment range. Due to extremely difficult conditions of operation of jumping (night, rarefied air, low temperatures, high weight and big size of the equipment, high drop speed due to the requirement of a short time of the aircraft presence in the drop zone), the AD-2000 parachute uses two reliable opening systems, one with a stabiliser and opening the main canopy with a ripcord or automatic device, and the other with automatic opening on the line. Using the stabilised opening system allows to significantly reduce the time of paratrooper training, by eliminating the need of flat fall training.
The AD-2000 uses two identical canopies, so that failure of the main canopy does not eliminate a group member, as he can immediately open the reserve canopy (with the same flying characteristics) and continue the flight towards the target with the entire team. Typical parachute systems have a smaller reserve canopy, so its use during a mission would require jettisoning of the entire additional equipment (the container), weapons, and the oxygen system, and thus failure to accomplish the mission by one of the team members.
Opening systems used in the AD-2000 make it suitable for instructor training. Modern parachute instructor training systems are based solely on ramair parachutes which provide much bigger opening.
The main problem lies in teaching the parajumper in flat fall. Upon leaving the aircraft the jumper must control his body so as to be in horizontal position when the main canopy opens. Positioning the body in a different way may interfere with the canopy opening and thus even pose the parajumper at the danger of losing his life. Thus much of the training is focused on learning the flat fall, which requires many sorties, thus increasing the training cost. Similar as it was the case with DEDAL troop parachute, co-operation was done with WSO at Wroclaw in order to perform flight testing of the prototypes of the new parachute. The AD-2000 parachutes are manufactured in co-operation with American companies.
DEDAL troop parachute is used by Polish Army.
