The plane which was not a multipurpose f26 stalma vigeneration (usa)

F-26 STALMA — South American VI-generation fighter. Developed by «Stavati» as a tactical substitution of F-16 Falcon. Title airplane reads for itself — STALMA (advanced multi-purpose light fighter with a small take-off). It was planned that he will enter the program from «DEM / VAL», which took place in 2004.

F-26 STALMA — integral triplane with a single engine, controlled by a single pilot. Wing sweep varies widely — 5-70 degrees. Provided great maneuverability and stealth capability for air defense. Has similar security and weapons to the F-117 Nighthawk, but the cost of the 1st plane is much smaller — about 25 million dollars. Start of project development — 1994. The final draft was ready by 1997. The company had hoped that after the creation of prototypes and test flight in 2006, will begin mass creation. Developers at the time said that the new plane will be delivered only South American allies.

Arrangement and design of F-26

The plane is sredneplanom with vastly varying wing sweep. Swept wing in flight is determined by automatic with manual control. The wing has a slightly altered profile of NACA 66-415 and is composed of titanium and the spirit of the 1st Special Alloys of the spar, ribs, and stringers of titanium and its alloys. On top of the wing is covered with titanium-filled casing consists of a graphite-epoxy composites. The interior of the wing — the fuel tank.

The edges of the wing is made of titanium and various composites. Leading edge slats is, back — the type of Fowler flaps. Management flaps and slats made using hydraulic cylinders developed by «Bertea / National».

To a set of supersonic speed, flight control is carried out by means of the ailerons. Spoilers, set in the central part of the wing provide lift control. Under the wing have four suspension assembly, allowing to carry up to 7,250 pounds of payload. At full load, the sweep is limited to 35 degrees.

The fuselage is made of three sections. The basic structure is made of alloys and composites. Feathering V-shaped type with angle of 55 degrees. In plumage provides cutouts for the console of the greatest sweep. The plumage is used when dialing supersonic, the lower end of the motionless and the top all-moving, is controlled in three axes. The moving part is inside the antenna and equipment, warning about radiation. The tail of the plane attached to the farm, which keeps the motor system.

The plane is set to hydraulic tricycle landing gear. The folding of the chassis — the frontal folds forward, the main — backwards. Landing speed less than 7 m / s. To control the supply of air fighter has 3 vozduhopoglotitelya. Ventral air intake is used at subsonic speeds, adjustable side are used only at supersonic speed.

The propulsion system — Turbofan F119-PW-100. Fuel loaded into the fuselage and wing tanks. Most of the fuselage-sealing tanks. Capacity of fuel a little more than 8 tons. To ensure fire safety mounted gas (inert) and fire system. Fuel is supplied from a single neck in one of the fuselage tanks. In the bow of the device has left refueling.

The cabin is designed for the 1st pilot and absolutely tight. For him, found a chair with a catapult «Aces II». Oxygen delivery is done by the system «Litton», for temperature control set kondyuk «AiResearch». One-piece canopy, drop-shaped, opening / closing is an electric motor or by hand. The cabin has a viewing angle of 13 degrees vertically, horizontally 40 degrees.

Control of the aircraft quad, elektrodistatsionnoe console installed. In the left part of the collected Communications, weapons, defense systems and navigation radar. In the right part of the collected motor control system, control system equipment, power systems, lighting, spare key systems and alarm system. Tsetr console is responsible for flight control. Apart from the control devices, with 3 LCD monitor. All monitors are interchangeable and show all the available information on the environment, weapons, the supplies of fuel. Right / left console with 2 LCD display radar data (front / rear hemisphere of the review).

Hydraulic cylinders provide the swing wings work from 2-hydro-independent with a working pressure of 275 atmospheres. In addition, the hydraulic system provide work chassis vozduhopoglotiteley, the brake system. The pressure in the system keeps the engine failed (due to a large turbofan appears quitting flight control). To overcome this pressure set batteries. In the aircraft is equipped with an additional power plant «Allied G250». It starts the engine and the main support system switched off the engine. Electrical generator is supplied with «Sunstrand» 90kW (10kW to spare). Power on the primary bus, it duplicates the spare tire (only the main system) motor run — a separate bus. Constant current is out with a 28 V converter. Four 24V BATTERY created to start the motor and the power of the central management console. On the starboard side of the fighter made connectors for ground equipment and supplies.

The fighter has developed radar «Hughes» AN/APG-73. Phased array antenna type. It is possible to install radar PS-05 / A or AN / APG 68ABR. In the navigation equipment includes laser gyros, integrated GPS, receiver equipment of different navigation systems. In equipment protective systems include transmitter EW equipment classified communications (voice) KY-58 TSEC, equipment defendant «friend or foe» AN/APX-109, equipment warning irradiation facilities traps AN/ALE-47/55. The DVR records the data and actions with HUD MFD, and data communications systems. In the black box is saved last 1.5 hours. As the payload can be suspended containers with additional equipment, such as navigational guidance station or stations.

The fate of the project

This aircraft is the work of a little-known project of the American company «Stavati», exhibited photos are 3D-modeling. Everyone who was interested in figuring out the truth on the F-26 STALMA, said that the company «Stavati» has no any relationship to the airlines, which really makes combat aircraft. The project is multi-purpose fighter had to intrigue European allies in the development of new and improved fighter with a small cost. The company’s website on the web is, it is on projects of various military and civilian aircraft designation unique designs. Pages with the F-26 STALMA no longer exists, although in 2000-2005 it was present on the website.

As they say military experts at, the cost of F-26 STALMA, or she could not be claimed by designers, creating the necessary components, the establishment of production, would eventually lead to a strong appreciation of the cost.

And in the end, even though the airplane structure is quite unique, but in general the plane is not very pleasant memory, because, as they say, just wonderful aircraft can fly perfectly.
