Piranha

For a start, aerolodka or airboat, it's not a hovercraft with which they are often confused, this is a special kind of terrain vehicles not only the rivers, as well as on the ice, swamps, rapids, etc.

Planing - the movement of the water in which the object is held on the surface only at the expense of high-speed water flow, that is, he slips on the water surface. When planing a sharp decrease in the resistance movement. The force required to release onto the plane, much higher than the force required to maintain this regime. Planing is one example of movement at the point of equilibrium sverhneustoychivogo.
Here's what Wikipedia tells us. But it is better, as they say, to see once than hear a hundred times.

Today I will tell you about his trips to the factory for the production of just such aerolodok

50 photos





Such are unpretentious gates meet us



Production of boats starts with the cutting of the material



This sinenkaja fabric called "Arctic" the manufacturer says that it does not lose its properties up to -70 degrees Celsius.



All cylinders are fitted with bulkheads that kleyut for just such a brutal formochkam



Finished cylinders lie and stand up (checked for leaks)



I apologize for the delay, suddenly surged work, who would have thought that was possible during working time =)

more cylinders are glued together into something resembling a boat already



Weaknesses glued to 2 times



The ends are glued again



So glued side cylinders



...



...



Masking tape leaves a lot
oochen


Glued to the bottom of the boat eyelets



Here they



By eyelets prishnurovyvaetsya reinforcement plastic scales protecting the bottom of the boat and allows it to move not only on water but also on land



Scales made here of just such plastic sheets



If the grommets on the bottom of boats are used to fasten the scales, then to the eyelets on the floor prishnurovyvaetsya powerplant, but about it later



Again they



The plant does not only production but also repair, as well as the modernization of their boats. For example, this boat lengthened to 30cm, which allowed her to gain more speed.



...



Oh yeah, I forgot to add, everything is done in the glorious city of Irkutsk.



The company is not afraid to experiment, though not all experiments reach the "conveyor»
But nothing, nothing ventured not drink champagne!



Such is the beautiful cabin was rejected because of too high weight



And now for the most delicious, plant final assembly and testing



Housings blades also locally produced



The only thing that is not done within the walls of this great enterprise, the engines and blades.



Basically this brand new aircraft engines manufactured by the opposition Rotax



But most small boats such as Piranha Piranha-1 and 2 are set such that's 2-stroke motorcycle, 50 horsepower engine, reduction gear are equipped with all the same firm Rotax



The blades come otbalansirovanye numbered and put the blade to his seat is very important, the speed of their rotation during operation reaches 3000 r / min



To put aircraft engines and aircraft computer, he wrote in memory of all the engine performance: speed, temperature cylinder head temperature ohl.zhidkosti, oil temperature, fuel level. And why did you ask him to record it, but for those that do not break Rotax engines, they can only break. And if the owner of the boat said that the engine broke down, data from the recorder will show where and under what conditions the engine was operated improperly. And therefore if the breakdown was caused by the customer, the factory will incur no costs for warranty repairs.



I think everyone learned lobovuhu Zhigulevskaya classics.
And why is it here? Ask you ...



... And that's why!
Three new, experimental boats Piranha 6
One of them will fall into our hands, but more about that later ...



Weight: 800kg
Capacity: 1300kg
Cabin for 6 people
Record speed of the boat put on Baikal 140km / h



The movement of this crown is 4.2litrovym engineering, V-shaped 8-cylinder, 280-horsepower five production TOYOTA



The engine contract, ordered in Vladivostok.
Before installation on the boat it almost entirely capital (except piston)



In fact it is a normal car engine, but with a reduction gear.
To my question, "But it is also a turbocharged possible?" The chief engineer smiled enigmatically ...



Again, I apologize for the delay, we will continue.

Shop by cornfields



But some instruments Aviation



...



They work not only the wipers and washer and even a stove.



2 plastic tank 70 liters



But now it's time to say goodbye to the plant and go on a long journey to the 1000 kilometer Krasnoyarsk



Trailers for these boats from the boat refurbished by setting a plywood platform.



The road was long, in some places on the federal (!) There is no asphalt road ...
But here we are in Krasnoyarsk, get down the boat into the water of the Yenisei



This Piranha-4, it's a bit smaller, but also can accelerate over 100km / h



It may seem that we're going in the field of water =) feels the way the way it is. Heavy boat up to speed pretty quickly, easily breaking the 100km / h, so much so that in the seat imprints.



...



But from pokatushek piranha-4 completely different feeling, it is 2 times easier to jump over the waves, and in general, as a motorcycle, but on the water surface.



Actually everything!
