An-22PLO Antei Cock
In 1965, at various levels, a number of resolutions were adopted on the development of antisubmarine defense means. According to the Decree of the CPSU CENTRAL COMMITTEE and USSR COUNCIL of 10/26/1965, the Antonov DESIGN BUREAU on the basis of the An-22 was developed the draft long-range aircraft for anti-submarine defense with a low-power nuclear-power-plant - the An-22-TPS.
Employees of the design bureau DC Antonov ordered with the brain's internal volumes gruzootsekah "Anthea". Immediately behind the cabin crew is a compartment for the motivated equipment and its operators, followed by domestic premises provided for relaxation, then "pasted" compartment for the rescue boat in the event of an emergency water landing, and at the rear of the cargo compartment positioned reactor protection. With all of this virtually no room for weapons. Mines and torpedoes offered to put in enhanced chassis fairings. But after the preparatory work for the assembly was revealed severe discrepancy: ready plane went very weary. Nuclear NK-14A engines with a capacity of 8900 hp simply could not provide the required flying characteristics. This dilemma decided by the design configuration of the reactor protection. Revised its mass is palpable decreased, but the level of protection is not only not injured, but even slightly increased.
The reactor was created under the control of AP Alexandrov. In contrast to previous designs, the new aircraft reactor equipped with their own control systems, automatic protection, etc. To control the reaction of a new nuclear plant control system was refreshed carbon rods. In the event of a critical situation provided a special mechanism, almost catapulting these rods into the reactor core. A nuclear power plant mounted on the aircraft #01-07.
It included acompact reactor developed under the leadership of A.P.Alexandrov, with cabinets, electrical, piping system and site specific designs of H.D.Kuznetsova. On takeoff and landing, conventional fuels were used, in flight power was provided by the reactor. These engine had a maximum power of 13000 and 8900 h.p. respectively. Estimated flight duration and flight range was 27 500 km.
Since the An-22 had the same engines as the Tu-95 (with other screws), the power plant repeated the Tu-119: the nuclear reactor and the combined turboprop NK-14A, all four. Takeoff and landing had to be carried out on kerosene (engine power 4 x 13000 hp), cruising flight - at atomic energy (4 x 8900 hp). The estimated flight time is 50 hours, the flight range is 27500 km.
The fuselage of the 6-meter diameter (the base aircraft has dimensions of a cargo cabin of 33.4 x 4.4 x 4.4 m) was to contain not only an atomic reactor in circular biosecurity, but also search and sight equipment, a complex of anti-submarine weapons and a considerable crew, required to service all this.
In 1970, the An-22 # 01-06, was equipped with a source of neutron radiation power of 3 kW and a multi-layer protective barrier, made in accordance with the later versions of the An-22PLO. The crew of the Kurlina made 10 flights with the source. In the course of 10 test flights revealed that the new version of one hundred percent protection was justified.
As part of the An-22PLO flights program was carried out in 1970, "Anthea" ["Stork"] with a neutron source, and in 1972 - 23 flight with small-size nuclear reactor on board. Crew V. Samovarova and s. Gorbika made 23 flights to Semipalatinsk, which had received the necessary data on the effectiveness of biosecurity. As in the case of Tu-95LAL, radiation protection was checked first of all. The reasons for the termination of work have not yet been made public. It can be assumed that the combat stability of the aircraft in the conditions of domination over the sea of aviation (first of all, deck) of the potential enemy caused the doubts.
In August 1972, the aircraft No. 01-07 had a small nuclear reactor in a lead sheath. The Office of nuclear reaction was carried out by carbon rods from the reactor and pumping the water into the outer contour, and in an emergency the rods were fired in an active zone. In the case of flight accident the reactor with the primary circuit thermal Exchange (and they have been implemented as a standalone unit) were separated from the airplane and parachute made a soft landing. Developers ensured that even if the plane crashed, the danger of radiation contamination would be minimal.
The only problem of techno touches connector of the 1st of the functional units. Because of the departed contact during the 1st flight of the reactor could not be included. Small repairs "in the field" has permitted to continue these flights. After the 23rd flight tests of AN-22 with a working nuclear reactor on board recognized the successful test aircraft delivered to the fleet and continued research and development work on the project of An-22PLO.
But in time the complexity of the design flaws of nuclear power plant led to the closure of the project. Outbound antisubmarine aircraft went super expensive and a Rocket. In the middle of the 1970s AN-22PLO project was closed. An-22 (No. 01-07) in 1973 was sent (without the reactor) back to the air force (CCCP-08838).
In addition to ASW variant, designers had the idea to create an anti-submarine variant by installing the missiles with nuclear warheads. However, the implementation of these plans, as well as the launch of a series of An-22PLO, was prevented by the end of the cold war and the collapse of the Soviet Union.
