Rrab — Molotov Bread

For the introduction of small high-explosive, fragmentation, incendiary and chemical bombs weighing 1-25 kg in Russian Union have developed a variety of media — stationary tapes, containers and Rrab (Rotative-diffusing bombs). We can say that Rrab predecessors were air dropped cluster munitions. Ammunition installed tail at 45 degrees to the longitudinal axis of the core. By dropping ordnance gained rotational motion with increasing frequency. Upon reaching this speed rotary motion, the cable having a weakened section, pulling together the body, due to the centrifugal force acts began to burst, and small live ammunition began to dissipate in the fall hitting a huge area.
Rrab produced in 3 versions:
— to one thousand kg (Rwork-1);
— up to half a ton (Rrab-2);
— 250 kg (Rrab-3).
Structurally Rrab are wrapped with thin walls, which were placed small bombs, technology, right at the airport, just before use. All Rrab were of similar design:
— warhead;
— tail section;
— the cylindrical portion.

The head part (cone and dome head) fairing was stamped from sheet steel (1 mm thick), which are connected between an electric welding. The cylindrical portion — 4th housing shells made of corrugated steel (thickness 1.25 mm), which are bent by a circular arc cross section is a respective aerial bomb. We Rrab-3 thickness flaps was 1 mm. To increase the rigidity of the longitudinal wing had 6 zigov. Rrab-3 had 4 straight ridge. Strength of flaps provided in the rolled edge flaps 5 mm steel rods, valves on the inner sides were welded steel strip of lithium. The tail section — the fairing with a cone made of 1 mm steel sheet. Connections were solid sheets of electric welding seam. Tail cone is provided with 4 folding wings. They are set by the struts and supports. Rrab-3 has three folding wing. Wings themselves made of 1 mm steel. Wings provide additional hardness ridges formed on the wings in the form of various complex shapes. This sets the geometry Rrab ancient patina color.

Inside the Rrab were broken up into sections, broken special discs made of plywood 10 mm wide. Determined by the overall length of the bay features equips small bombs that were used for each Rrab personally. Rrab-half could be inside to 4 compartments Rrab-3 to 3 compartments. Before installation of small bombs in internal bays Rrab them head-set fuses. Laid low ammunition moderately warhead for / against the direction of flight. Every three Munitions set in a row, facing away fan fuses half-turned and tied together with wire plugs.

Russian bombs had low weight adjustment for length, often because compartments were filled with one hundred percent. When filling the compartments small guided munitions documents that are prescribed in such a case, leave blank the upper sections of the tail. So Makar, Rrab feel more stable on the trajectory of the flight. Prior to the 40s Rrab mans only one type of aircraft bombs, and 1-caliber. Ending the war with the Finns brought with it a revision of picking Rrab. It was possible to complete Rrab different ammunition, but only in each compartment had to be small bombs 1st caliber.

Any of the manned compartments tied up with 2 discontinuous rings. If a small ammunition were sufficiently high caliber, cut blew down by 4 rings burst type. Free space in the compartment with the Manning ammunition killed bars of wood bomb container. On equipped with a body dressed Rrab system implements of production, the tail and the head fairings, set the stabilizer wings in the folded position. When you reset Rrab the plane, pin holding the stabilizer rope, yanks, wings disclosed the flow of air into the firing position, which recorded the spetszamok.

One of the main problems in the development of Rrab was trouble-free release of bombs mounted system in the commission of bombing. Rods made of ropes, lock the bomb rack tore the retaining pins, opening it locks the suspension, and freed from unnecessary Rrab element. After which the remaining iron cables, tapes and suspension "loose" under the plane. It is not much influenced by low-speed aircraft, but the high-speed media is threatened of losing either bring into disrepair fuselage and wings. In 1940 Rrab-3 received an upgraded suspension system, which, after dropping Rrab-3 gun was separated from the castle bomb racks. Remained "unseparated" cables locks and suspension systems uncovering plumage. After about 10 seconds of free flight Rrab combat gear, experiencing enormous centrifugal forces tearing the ring and fly away, covering a large area of chosen target. Regardless of military equipment Rrab they can be used to destroy enemy personnel:
— in open areas;
— Field shelters;
— on motor vehicles;
— in armored vehicles.
Rrab with incendiary ammunition used for igniting buildings, warehouses, timber type. Regardless of staffing, and marvel at the height of the area was as follows:
— height of 3 km Rrab-1 — 230-950 square meters, Rrab-2 — 280-1300 square meters, Rrab-3 — 220 — 850 square meters;
— height up to 5 km Rrab-1 — up to 1200 square meters; Rrab-2 — up to 1700 square meters, Rrab-3 — up to 1,100 square meters;

According to the draft Rrab armed bombers TB-3-4M-17 and TB-1. But grown in popularity these munitions and adoption of a number of aircraft, allowing Rrab on other planes:
— Rrab-half — languid 3RN bombers TB and TB-3 bombers distant IL-4 and DB-3;
— Rrab-3 — far bombers IL-4 and SB (MN).
"Combat" baptism rotative-diffusing bombs were in the Finnish War of 1939-40. The main drawback was seen as staffing Rrab technicians on the ground that during the war involved in the preparation and repair of aircraft. This has a negative impact on the use of Rrab during WW2, where their use was conducted with even lower intensity.

Equipment Rrab sought enormous amount of time. Every small bomb had to cook and put in a drawer, like oranges or lemons in a box, and they placed more than one hectare. In case of cancellation of flights tape was necessary to discharge the same amount of time. Sharp-tongued our guys have deciphered Rrab in their own way — work, work, and useless … Although, actually, she acted quite well. ".

The Commission would consider military actions during the Finnish War, pointed out that for the successful implementation of Rrab requires a painstaking preparation, because the incorrect assembly Rrab led to a false detection and actuation. Small ammunition were unable to acquire the correct position and cock the fuses. Commission was also established and cause tremendous losses spacecraft during the Finnish War. How is the loss of machines were not only in the large air, and ground forces. Because many of the infantry commanders perceived for the downed plane Rrab part with th
eir fins as part of the tail was shot down / crashed / scorched aircraft.

The Finns called Rrab-3 "Molotov bread baskets" (Finnish Molotovin leipäkori), and the smallest bombs — "Molotov bread bins." According to one version, it was due to the fact that the Russian People's Commissar Molotov denied reports of the bombing of Helsinki, stating that with planes dropping bags of bread for the hungry Finnish workers. According to another version, this title could be an allusion to the Molotov cocktail.

By the early 40-ies Rrab-1 is removed from the production, Russian enterprises produced only sets Rrab-2/3. As it became clear the Germans were seriously interested in similar solutions. After the end of the Finnish war, German spies inspected the virtually all parts / dumped Russian Rrab and more worthy of their attention was taken to Germany.

Small bombs used to complete Rrab:
— Rrab-1 — ZAB-1E / 2,5 m, AO-8M2/8M3/8M4/8M6/10/20/25, AOH-8/10, AX-8, HUB-25, AP-32;
— Rrab-2 — ZAB-1E / 2,5 m, AO-8M2/8M3/8M4/8M6/10/20/25, AOH-8/10, AX-8, HUB-25, AP-32;
— Rrab-3 — ZAB-1E / 2,5 m, AO-8M2/8M3/8M4/8M6/10/20/25, AOH-8/10, AX-8, HUB-25, AP-32;
