7-section precision parachute Malva-24SK

Appointment
The parachute sports system “Malva-24SK” is designed to perform all types of jumps both by individual athletes – paratroopers, and groups of parachutists from airplanes and helicopters designed to perform parachute jumps, when it is put into operation immediately after separation from the aircraft or with a delay of opening valve knapsacks.

Technical details
The design of the Malva-24SK parachute sports system with a total weight of 105 kg provides the following tactical and technical data:

reliable operation with the introduction of the parachute system at an altitude of up to 2000 m above sea level at a flight speed of the aircraft from 39 to 62.5 m / s (140-225 km / h) from any aircraft designed to perform parachute jumps, both with immediate commissioning and with a delay in opening the knapsack valves;
overloads arising in the process of disclosure:
main parachute no more than 10 units;
reserve parachute no more than 12 units;
minimum safe altitude for use when leaving a horizontally flying aircraft at a flight speed of 50 m / s (180 km / h) with immediate effect:
the main parachute is 400 m, while the decrease in the parachute is controllable;
reserve parachute 150 m, with a decrease in a fully filled parachute for at least 10 seconds;
the average value of the vertical rate of descent with fully released control lines, reduced to the conditions of a standard atmosphere:
main substation no more than 5 m / s;
spare substation no more than 6 m / s;
stable operation in all planning modes with smooth retraction of control lines;
average parachute turn time by 3600 when pulling one of the control lines:
main SS no more than 8 s;
reserve substation no more than 5 s;
the average maximum value of the horizontal component of the planning speed with fully released control lines:
main substation – at least 8 m / s;
reserve substation – not less than 9 m / s;
safety of landing in the wind near the ground up to 10 m / s with the parachutist approaching the target against the wind;
detachment of the main parachute from the suspension system, both on the ground and in the air;
force required to bring the parachute system into action:
main parachute no more than 98N (10 kgf);
reserve parachute no more than 157N (16 kgf);
the effort to strike the annular locking devices of the main parachute is not more than 157N (16 kgf);
the use of a reserve parachute in case of abnormal operation of the main parachute when the main parachute is completely disconnected;
the introduction of a reserve parachute by the manual opening link when disconnecting the failed main parachute, or by devices: the PPK-U-405AD semiautomatic device and the Saipres machine gun if the main parachute is not put into operation.
the introduction of the main parachute into action only with the right hand with a soft exhaust parachute;
automatic disconnection of the semiautomatic device from the reserve parachute at the moment of pulling up the free ends of the main parachute;
PS performance at temperatures from minus 30 to plus 40 ° C;
assigned resource PS within technical specifications:
for the main substation – 600 applications;
for emergency substation – 10 applications.
NOTE. Based on the materials received from operating organizations, the development company will increase the assigned resource.
the mass of the parachute system without a parachute semiautomatic device, a portable bag, an athlete’s bag and a laying cloth is not more than 12.5 kg;
overall dimensions of the PS laid in a satchel:
height not more than 0.25 m;
width no more than 0.39 m;
length no more – 0.55 m.
