Sukhoi Su-38. Photo. Story. Characteristics.


The Su-38 is an agricultural machine, which was developed by the Sukhoi Design Bureau to facilitate agricultural work, namely it is made for spraying chemical liquids and solids for fertilizer or soil pest control. Sukhoi Design Bureau designed the first plane of this type before it is engaged in manufacturing of military and sports planes. To date, the aircraft such as Su-38 no longer manufactured.

Design features of the Su-38

The aircraft is designed for the type of freely carrying monoplane, which controls one pilot. On the wings of the lower arrangement is hung standard equipment that produces spraying chemicals. Spray System is made by the American firm, and has the name "Translend." But 2002 years started to equip the aircraft spray system, which is designed in the Sukhoi design bureau. The new system is inexpensive and does not yield to the American counterpart.


To reduce the weight of the machine designers have used a large number of composite materials that enhance the vitality of the device and are reasonably high rigidity body. In addition, these materials will improve comfort, fire safety, corrosion resistance of the device.

The whole design of the Su-38 designers thought sufficient detail. The aircraft has a set of systems that enhance safety, because this farm machine operating at very low altitudes, which increases the percentage of accidents. Due to the fact that the machine operates mainly at altitudes of up to 1 15 meters, there is a danger of collision with trees or poles and power lines. The global accident statistics indicates that more than 70% of agricultural aircraft accidents occur because of collisions with objects placed on the ground.

To increase the safety of the pilot cockpit is equipped with a special frame, which does not allow the body to crush the cab and cause damage to the pilot. It is also equipped with a cockpit seat which absorbs shocks during the emergency landing. Before the cab windshield installed special metal bump that prevents shocks branches or other objects. Buffer is connected to a cable car with a tail part of the machine, namely the keel. This allows you to throw the rope through the device wire of power lines that can get in the way of the car. The cockpit is completely sealed, allowing you to avoid getting chemicals in the body of the pilot in the processing field. The air enters the cabin after the pass through the filtration system, and is clean, non-hazardous.


Aircraft of this type has 3 thousand flight hours or 10 years of operation. This was achieved due to the fact that all components of the machine design are made through computer analysis and modeling.

In addition to the initial version of the aircraft as an agricultural machine, Su-38 can also be used in other assignments. But almost all the machines are intended for use in the field.

Characteristics of the aircraft Su-38

This agricultural machine has been equipped with an engine of Czech production, which gave power 235 horsepower. Engine Single row, which includes 6 cylinders. This powerplant cooling air during flight. Motor drives the screw, which consisted of three blades, a step he changed the rotation during the flight. The good quality of the engine can be called is that it runs on gasoline, aviation fuel which is much cheaper and much more widespread. Also in operation for years 3-4 aircraft need small repairs and adjustments due to the reliability of the power plant.

The aircraft is equipped with a tricycle landing gear, tail stand - casters. All gear wheels are braking system, which controls the hydraulic unit. With regard to the fuel system, it is represented by two fuel tanks which are placed in the caisson system. They can fill 130 liters of fuel. The machine is made mechanics, only the elevator is equipped with electric drive and all mechanical flaps.

For more efficient use of agricultural work aircraft equipped with the system of GPS-navigation.

The Su-38 is equipped with outboard equipment, which consists of a tank of chemicals, and the bar with nozzles. Tank chemicals can be removed. As to the spray bars, it is fastened to the pylons and wings also can be removed if necessary. To remove these systems and customize them to another type of spray chemicals will only have half an hour. When filling the tank chemicals contact personnel to hazardous substances completely excluded.

To date, the project is actively developing. Aircraft such as Su-38 is popular among customers because it is reliable and cheaper to maintain. This project is quite new aircraft, since only his first flight of the Su-38 2001 carried out in the year.

Sukhoi most known for its military development, but the designers and engineers to create aircraft for civil aviation. One of the bold, innovative and ambitious projects was the creation of an aircraft capable of speed up and simplify the work of the people, leading agriculture on an industrial scale. To do this in the KB began developing the Su-38 - airplane with a tank for chemicals 500 liters capacity and the ability to install any spray equipment. The plane created essentially of composite materials, which ensures a proper lightness and safety, as well as satisfactory while flying at low cost fuel. For this class of aircraft equipment inherent protection against ingress of harmful substances in the cockpit. The Su-38 to achieve this goal using pressurized inflating. Since the aircraft is flying at very low altitude, there is a risk of collision with obstacles, such as with a pillar, so below the cockpit is equipped with an additional frame stiffness. Overall, the aircraft meets the requirements of pilots involved in this area, but the project was commercially viable because of the rapid deterioration of the shell plating and engine, so the plane did not go into production, and not finding the consumer.
