Ka-10. A photo. History. Characteristics.

 

Work on the design of the Ka-10 began on AKB them. NI Kamov in 1948 year. In general, rotorcraft continued the line, and the basis for it was the Ka-8.

Thanks to the coordinated work of the staff clearly KB, to develop Ka-10 took only a couple of months. Unlike its predecessor, the new helicopter got a little. Ceasing the engine that generates 55 hp - AI-4G. Its designed specifically for this model monoplane. Also 200 mm diameter was increased rotor. This was achieved by lengthening the blades, which is why decreased filling rate. The design of the blades remains the same as in the Ka-8, but control scheme is now rotors for changing the collective pitch to meet the movement of sleeves splined shaft.

It must be remembered that the design of the Ka-10 held immediately after the triumph of the Ka-8, so experts Kamov bureau tried to keep the design of the helicopter as close copying his predecessor. While once 4 KB (im. Yakovlev, Mil, Kamov and Bratukhina) engaged in the development of the first Soviet helicopter.

The jurisdiction of the Yakovlev Design Bureau. Kamov was a take-off test area at the airport Izmailovo, where he passed the first tests of the Ka-10.

30.08.1949 was made the first flight over the territory of a helicopter airfield Izmailovo. At the helm was a test pilot MD Gurov. The flight was not entirely smooth: identified errors in the collective pitch lever rotors.

The helicopter was equipped with a radio, and a compressed air tank rocket launcher to start the motor, brackets for buoys. It establishes a system bailout. The essence of her work was to Releasing the seatbelt pilots and pilots die and fall with parachute back after folding backrest.

One of the final flight during a test flight began on the duration, which is also performed Mikhail Gurov. The helicopter was lifted to a height of 200 m above Izmailovo airport. In order to increase the efficiency of the flight, the pilot decided to test drive a car at rated speed. The circumferential speed of the blades was not enough - the helicopter skabriroval, floating in the air and fell. On the way to the hospital died Gurov.

Gradually, problems with stalling the rotor blades began to repeat, and it caused a huge range of criticism of the Yakovlev Design Bureau. Kamov. In particular M. Miles said that Ka-10 not able avtorotirovat. Nikolai Ilyich Kamov cited in his defense overseas examples where such problems eliminated by changing the collective pitch of the rotor.

Fully refute arguments ML Lily was only in practice.

Since May 1950 years aboard Ka-10 to run the test program provided Kaderovskomu I., who was able in a short period of time to master control of the helicopter. In those days, a complete set of test aircrafts did not put a lot of recording devices at Ka-10 present only barospidograf, other indicators of devices and instruments were recorded in memory of the pilot.

It came down to check coaxial helicopter to the possibility of autorotation. To perform this procedure specifically derived parameters the engine speed and the rotor next to each other. The pilot deliberately unraveled the engine speed to rotor speed, that was a reserve power. Operation autorotation led Kaderovskogo successful, thereby completely denying the words of M. Mile.

In 1951 year it was decided to build a military version of the Ka-10 commissioned by the Soviet Navy. During the period of 1952-1953 years 9 made combat helicopters. They were divided into different sections to perform the tasks of the Navy. The military version of the Ka-10 took part in the observation of objects, searching for mines, submarine detection, conducting aimed fire. Raising the helicopter in the air even carried out the cruiser. Even in the wind in 26 nodes managed to raise Ka-10 and put him in the cruiser "Maxim Gorky". For example, the Ka-10 created basis for the use of helicopters on ships, helicopter carriers.

Given the technical operation of the aircraft, soon it developed the first modification of the Ka-10M. Differences from Ka-10 could find a great deal. In fact, it was a completely new coaxial helicopter. It introduced a new management system efforts rotors with intermediate sliders that will reduce the pressure on the lever and pedal control. To improve directional stability to the modified model set dvuhkilevoe plumage. Screws in diameter was increased to 6,12 m, which added traction and reduce the probability of failure of the air flow from the fan blades. The first flights of Ka-10M began in 1955 city, and the car immediately became popular thanks to the excellent performance maneuverability and ease of management.

Design Ka-10

Ka-10 is a structure built of metal tubes with a diameter of 8-18 mm. The central part of the design take-4G AI engine and the pilot's seat. On the sides are placed lodgements that serve fastening cylinders which are filled with air under pressure and perform a support function.

The container is divided into four sections, and is made of two-layer rubberized material. The lower part of the container glued rubber sheet thickness 1,5 mm. This feature allowed the landing gear to land a helicopter on virtually any surface (water, earth, the deck of the ship, etc.) and also successfully raise the machine in the air.

The front of the car takes a fuel tank 33 l. Just behind the pilot's seat placed struts tail. Nearby, in the lodgment of cylinders, two racks fixed antenna radar RCI-3M1. Ka-10 has dvuhkilevoe vertical tail fins with fabric covering.

The torque is transmitted from the engine to the propeller blades via two gearboxes: a motor (bottom) and distribution (top), which are connected to the main shaft. The upper and lower screws are rotated in opposite directions. They and transmits torque upper gear. The motor gearbox are devices that allow the engine is running without engaging the rotors, which helps to keep the car in the air in an emergency.

The installation angle helical blades vymerivaetsya by moving the lever control helicopter, pens a "step-gas" pedal and flight control. All components of the control system interconnected with the mechanical wiring and aggregates differential collective pitch. The inclination of the control lever causes the helicopter to tilt mechanisms and skew angles change rotor blades. As a result, one screw turns simultaneously increase, and the second - are reduced, allowing the helicopter to turn in the right direction. If the tap handle, "step-gas", it is possible to obtain an increase or decrease in thrust of the blades, due to changes in fuel supply quantity to the engine is lost or enhancing its capacity.

The equipment Ka-10 includes a number of flight and navigation equipment for operations in reduced visibility and devices, responsible for the operation of the engine. These groups include:

  • altimeter VD-12;
  • speed indicator DC-140;
  • Compass Key-11;
  • Vario BP-10;
  • Index rotor speed;
  • Index sliding.

Radio contact with the ground is provided by installed on board Ka-10 radio RSI-3M1 that worked on batteries.
