The issue of deep modernization of the Mi-14 almost solved

 

Under the shortcomings that remain with Mi-14 and after the upgrade, it would be logical to start with the project «0».

  • 1. Former Deputy General Director Valery KHP Kartashov believes that "attention should be paid to issues of stability:" In the excitement of more than three points, if the screw is turned off, the car overturned. Such cases were in the North. "

  • 2. "As the capacity of the machine is not allowed to simultaneously carry detection means and necessary for the destruction of the submarine weapon, Mi-14 worked in pairs: one was looking for the submarine, the second of their attack."

  • 3. When the helicopter taking off from the water had a penchant for burying the nose of the helicopter into the water.

Hardly fit for something better as a naval helicopter, the helicopter except the transverse scheme for marine expanses of large scale two rotors does not matter, but the wings will provide reliable lateral stability. And not only!

And so in order: modern liners console wings are bent upward, the marine rotary wing should be bent down and at the ends to fix the transverse stability floats. Above are the screws from the Mi-38 serial helicopter, which will receive rotation from one D-136 engine (the future Russian PD-12V engine is only in the minds of the designers) installed on the fuselage and that will have the same speed in flight under any flight conditions . The sea version can allow to have instead of two engines only one! Why? Yes, because during the entire flight under the rotorcraft - amphibian there will always be a water surface, which in the land version is equivalent to the landing strip and if the engine fails, the device will easily land on the water. Again, this is possible even when this engine is one for the entire helicopter. But in this case there is a more reliable way out of the situation: to install on the tail fin stabilizers on the engine with pulling screws, with which the rotorcraft will be able to continue flying in the mode of the gyroplane. It should also be taken into account that the crew, with a small reserve of power of the TMD of the tail stabilizers, can use the air cushion like a ekranoplan, and the air cushion will exert its positive influence not only on the supporting screws, but also on the wings, which will generally facilitate the work of the pulling screws .

Moreover, if the main engine will give up the tail and one theater, the rotorcraft - amphibious mode boats will be able to sail with another tail and nose of the theater as opposed to single-rotor helicopter will not dig, and vice versa - to rise. It is for this reason "taxi speed Mi-14 limited to 20k / hr., And the rotorcraft will be able to steer at a speed speedboat, and this in turn will not wait for help after an emergency landing, but in the mode of boats to sail confidently to the base.

I think that Kazan Helicopter designers that previously produced helicopter - amphibian rotorcraft proposed version with one main engine and two theater on tail stabilizers would be on the shoulder. And designers of cost centers already be a lot of trouble: it's time to think about replacing obsolete Mi-26, A long-standing battle replacement helicopter landing Mi-24To continue work on the advertised speed helicopter PSV.

The author likes to cross pattern. Who has not found themselves in the implementation of serial helicopters. Maybe because it is not as effective as it would like the author?
And in general, thoughts about "rotorcraft - amphibious mode boats ..." give violent fantasy author, divorced from reality. In the middle Bartini projects.
