    fighting machine BM-14-17 (index 8u36) Fighting vehicle BM-14-17 (index 8u36) was intended to suppress manpower and fire weapons, destruction and suppression of artillery and mortar batteries , mechanized destruction of the enemy, destroying a tree light field-earthworks.

    Development BM-14-17 was carried out under the leadership of AI Yaskina and was completed in 1958. BM-14-17 created taking into account the experience gained in the design of other combat vehicles BM-14 family, and has been completely unified with them on the ammunition used.

    fighting vehicles of this type received, primarily for service connections podradeleny rocket artillery Marines Navy. BM-14-17 for a long time produced the Soviet defense industry was repeatedly modernized and adopted in many countries.

    Composition

    fighting machine BM-14-17 (index 8u36) Fighting vehicle BM-14-17 (BM-14-17M 8U36M index) is a self-propelled rocket launcher, consisting of artillery pieces and modified truck chassis.

    Artillery unit consists of seventeen trunks (upper row - 9, bottom row - 8), cot, with swivel base, lifting and balancing mechanisms and locking mechanism in its stowed position, sighting devices, electrical equipment and special equipment chassis. Cradle is used to mount trunk sighting devices and electrical equipment. Cradle - rigid welded box, connecting with the axes with the base forms part of a swinging combat vehicle. Base consists of a pin, the pin housing, rotating, lifting and counterbalancing mechanisms and locking mechanism in its stowed position. Pin mounted on bearings in a housing pin, along with the swinging part and twist mechanism, as well as lifting and balancing mechanism is a rotating part of the war machine.

    rotary mechanism of the worm, and Linkage screw type. Counterweight mechanism spring, push-type, serves to reduce stress on the handle actuator handwheel hoist. Locking mechanism in its stowed designed for locking the rotating and oscillating parts of the machine in the stowed position. With the guidance package guide mechanisms may be induced in a vertical plane in the range of angles from 0 ° to +50 °, the angle of horizontal firing is 140 ° (70 ° left and right of the longitudinal axis of the machine).

    sighting device consists of sight and panoramas. When shooting night sight range and pan covered with a special system, powered by the battery combat vehicle chassis.

    As a base for BM-14-17 used a modified truck chassis GAZ-63 and GAZ-63A. Modified chassis of GAZ-63 differed from the GAZ-63A only by the winch on the front end of the frame in front of the radiator and driven by the motor vehicle. Special equipment chassis combat vehicle consists of a seat, cab protection, front and middle decks, racks tent, box of spare parts, spare wheel bracket and jacks. Fighting vehicle BM-14-17M was placed on the chassis of GAZ-66 (see diagrams in combat and stowed).

    When translating

    launcher from traveling to combat sight glass cockpit closed folding armor panels and aft chassis hung above the ground with two poles with screw jacks. It takes about 1.5 minutes. Shooting from the launcher can be carried out by single shots, but the main firing mode - volleys. Volley duration is 7-10 seconds. Management of shooting carried out from the cabin or using the keypad up to 60 m from the war machine. Loading the launcher is done manually for about 1.5-2 minutes. Position is a crew of seven. On the march vehicle commander and driver are placed in the cockpit, and the rest of the calculation - the seats mounted behind the cab open. Fighting vehicle, charged 17 shells can make the march to 650 miles without refueling and additional opening salvo fire in 1-2 minutes after "To battle".

    main type of projectile for the BM-14-17 (BM-14-17M) was a 140-mm unguided missile turbojet M-14-PF (see description).

    In high-explosive projectile M-14OF ammunition in these combat vehicles were smoke burning shells of M-14D (see description).

    were developed and also produced a 140-mm turbojet with warhead curb warfare agents.
