High-speed amphibious hovercraft PARMA 15 is designed to carry up to 1450 kg of cargo or up to 14 passengers. Hovercraft belongs to the class of “passenger” hovercraft and is designed to transport passengers across water bodies in summer or winter, including those with short-term shore exits. The boat is capable of overcoming smoothed ledges up to 80 cm high and not smoothed – up to 40 cm. The boat is capable of reaching a speed of about 70 km / h on water. Operation is permitted at an outside air temperature from -40 ° C to + 30 ° C and a maximum wind speed of up to 12 m / s at any time of the year during daylight hours. In all cases of load, the Hovercraft can be operated during daylight hours in water areas, with waves of no more than 1.2 m 1% security. Movement of the boat is allowed with the specified wave both in the air cushion mode and in the displacement mode. When driving on ice or snow-covered surfaces, operation is permitted on all bodies of water. Operation is allowed on any other flat solid surface, in extreme shallow water and swampy surface.

Main dimensions and characteristics

 

Housing

The hull of the vessel is made watertight, divided into 5 watertight compartments by 5 watertight bulkheads. As the material of the main body, set, foundations, sheet and profile rolled products from aluminum alloys are accepted. Flat products are used of the Amg5M brand, all-Union State Standard 21631-76. Profile rolled products of the Amg6M or D16T grade in accordance with all-Union State Standard 8617-75. The body of the hovercraft is riveted (with the exception of small parts made by welding). The tightness of the outer contour of the boat and the corresponding transverse bulkheads is ensured. The tightness test is carried out in accordance with the test scheme and table. Corrosion protection of the body is provided by the use of aluminum-magnesium alloys, which are resistant to corrosion in river and sea water. Additionally, it is envisaged to paint the outer and inner surfaces of the body with paint and varnish materials.

 

Salon

The passenger compartment is equipped in the front with two soft passenger seats, including one for the captain. Along the sides, there are six double lifting sofas-lockers, under which lifejackets and property are located. The covers of the sofas can be folded out, forming a sleeping place measuring 1800×2000 mm in the aft part of the cabin. The arrangement of armchairs and sofas is subject to change. There is an option with soft seats for all passengers. The deckhouse is made of a three-layer structure, the middle layer of which is insulation. The outer layer is made of fiberglass based on polyester resin with fiberglass reinforcing material, coated with a colored resin (gelcoat). The middle layer is made of tiled foam. The inner layer is made of fiberglass, pasted over with a lining – pile fabric

 

Engine

The hovercraft is equipped with two engines of the American brand Cummins ISF 2.8, 130 hp each. An increase in power up to 150 hp is possible. by increasing the maximum crankshaft speed. A four-stroke, four-cylinder, electronic Common Rail diesel engine with in-line cylinders and common crankshaft pistons, with single overhead camshaft. The engine has a closed-type forced circulation liquid cooling system. Combined lubrication system: under pressure and spray. The Kamins 2.8 (Cummins ISF 2.8L) engine is installed on vehicles manufactured by OJSC GAZ, in particular, on commercial vehicles of the GAZelle Business and GAZelle NEXT families. Due to its prevalence, the engine is well known to services, and spare parts and consumables for it are not expensive and can be easily found in stores. Today we can safely say that this engine is the most widespread commercial diesel in Russia. The engine is equipped with low temperature starting aids. An electric coil is provided for heating the air in the intake manifold. The fuel filter is also electrically heated. The Cummins ISF 2.8 engine has very low fuel consumption. The engines are standardly equipped with a turbocharger with an intercooler, that is, with pre-cooling of the air supplied to the charge. Thanks to the use of turbocharging, it was possible to provide high power and torque with a sufficiently small volume. At the same time, the presence of a turbine does not impair the efficiency of the engine – its fuel consumption per vehicle ranges from 8.5 to 10.3 l / 100 km, depending on the speed and operating mode. The engine has a traditional design. It is based on a one-piece cylinder block (made of gray cast iron) and a cast head; inserted milled liners are used in the block, which facilitates cylinder repair. The crankshaft is also made of gray cast iron and is integrated with the crankshaft position sensor pulley and toothed disk. The camshaft is one, located at the top. The motor has 16 valves (4 per cylinder), made of heat-resistant steel, their stems are additionally chrome plated. The valve drive is traditional, through rocker arms. Interestingly, all valves have the same design, but are not interchangeable. Timing drive – chain. The engine is equipped with Bosch Common Rail fuel equipment, the fuel injectors are top-mounted, they are installed in the central part of the cylinder. This solution has greatly simplified the engine without significantly degrading its performance. In general, the Cummins ISF 2.8 is a simple, reliable and unpretentious engine with good characteristics and adapted for operation in Russian conditions. Thanks to the design features, a simple device and the use of time-tested solutions, it was possible to achieve a high resource – the manufacturer claims an engine resource of up to 500 thousand km (for a car), in practice, the engine can last longer with proper operation and maintenance. The engine is currently being manufactured at the Cummins FOTON joint venture in China.
