In the 1950s, China supplied the Russian Alliance seaplanes Be-6. It was the only aircraft of this type, used in China's armed forces. After 15 years of using the Be-6 absolutely outdated and China takes the decision to start developing its own seaplane. Since then, China is neither technical nor scientific basis, the creation of aircraft, as well as many high-tech development, was not a strong point of the defense industry.
In the second half of 1960 began the design and development of a new seaplane. The main developer — CB Harbin Institute of Plant and hydroplanes. The military needed a multi-purpose seaplane kitted out strong and economical performance turboprop engines. He had to change in service seaplane "Be-6". Multipurpose seaplane gets the title of SH-5, translated means "sea bomber model 5."
Seaplane with board number 01 in the incomplete complete (housing), was used for static tests in the period 1970-1974. As previously noted, China embarked on a new path of development, experienced an acute shortage of prepared professionals and designers, because the first test aircraft SH-5 was built by the end of 1973, he received the board number 02. In the sky the first Chinese seaplane managed to climb into the sky in the spring of 1976. A major test of the seaplane was completed already in 1985. They participated 6 multi-purpose maritime bombers.
After completion of the test four planes of 6 (board number number 04, 05, 06, 07) are transferred to the use of naval aviation in China in September 1986. A fascinating feature are significant differences from those of pre-production prototypes for service seaplanes. Home base — and airfields Kuingdao Tuandao. According to the available disk imaging, in 1999 in the Chinese Navy flying boats on 7 SH-5. On this day, it is clear on the 3-operated seaplane SH-5 to carry out search and rescue operations and 1st seaplane (side number 06) to provide fire safety «PS-5".
Arrangement and design of Harbin SH-5
Chinese designers did not go too far in the construction of the Russian predecessor — the seaplane Be-6. There have also been applied to parts of the transporter «Y-8" (similar to the An-12). Chinese seaplane has a tighter aero scheme vysokoplana with straight wings. Base — the boat, ending a longish tail and feathers. To control a flying amphibian on the surface to the base of aqua boat steering wheel mounted controls. Stability of the aircraft on the water provide a non-retractable wing floats are running, they are installed on the N-shaped struts.
There are perceptible differences of the seaplane, which ultimately made it similar to the Russian "Be-12" and the Japanese «Shin Meiwa US-1A»:
— cockpit received teardrop-shaped;
— nose cone of the radar antenna is designed as a seaplane at the Be-12;
— retractable gear aircraft type.
Landing gear Chinese designers have been using a standard tricycle. The front two-wheel stand, the main — unicycles. Landing gear got pneumatic oil springs. Bow-hour after takeoff develops forward, the principal — a turning point in the niche boards. The peculiarity of the Chinese chassis is a small lumen in the commission of takeoff / landing with aqua surface.
As the customer ordered, equipped with amphibious flying strong engines WJ-5A1 "Dongan." These engines is a Russian analogue of AI-24. Four engine turboprop aircraft with capacity to provide 12,600 hp Three cargo compartment made in the bow of the boat. The middle part — it's equipment bays search, telecommunications and hardware compartments. Central compartment is the operator's compartment, where there are 3 operators that produce management board equipment. All internal compartments are connected by a corridor, locked compartments with watertight doors. In the structure of the onboard equipment includes an inertial navigation system, radio compass, the sensor definition of magnetic anomalies, radar altimeter, Doppler radar search. Full crew — 8 persons, consisting of the commander, copilot, navigator, engineer onboard, radio operator and technician-operators.
Armament seaplane SH-5 consists of:
— Remote installation barreled gun caliber 23mm «Type 23-1»;
— anti-ship missiles such as the C-101;
— compact ASW torpedoes;
— deep bobmy / mines of various calibers;
— resettable equipment for radiogidroakustiki;
— rescue / emergency equipment.
The total desired load multi seaplane — 6 tons. It is mounted on four nodes under the wing and is located in the aft compartment. Example, on a combat patrol seaplane flies armed multipurpose 2 C-101 anti-ship missiles and torpedoes 6 on the outer and inner pylons, bombs, ammunition / min (1h3000/3h1000/6h454 kilogram) radiogidroakusticheskie buoys, rescue and emergency equipment.
— 01 — pre-production layout. Was used for static tests;
— 02-03 — pre-production models. Used for flight testing;
— 04-07 — series models. Put into service.
— SH-5 — Multi-Purpose (basic version) seaplane;
— SH-5A — some of the series of prototypes have been converted to an electrical conducting reconnaissance;
— SH-5B (PS-5) — firefighting seaplane. Remodeled board number 06, the required load — 8,000 pounds of water.
The main features:

— ceiling height — 10.2 km;
— combat load / max — 6000/10000 pounds;
ent — RPC, torpedoes, mines, bombs, extra equipment.
The fate of multi-purpose seaplane SH-5
Normal production seaplane did not wait, of course, this prevented significant deficiencies avionics, and will not provide the design features of search and destroy surface ships and submarines. By the way, the RPC "S-101" also did not go into mass creation for similar reasons of technical nature.
Seaplanes operated at a given time are used in the «PLA Navy North Sea Fleet» on spetsbaze Kuingdao seaplanes. Main purpose — maritime patrol.
