JAS-39 Gripen



Multi-purpose combat aircraft JAS-39 Grippen company SAAB / British Aerospace is a single-engine monoplane with a simple delta wing and a fully floating adjustable slats - aerodynamic configuration "duck" (horizontal rudders handed down before draining).

The aircraft is characterized by the natural (deliberate) no wind resistance, to achieve high maneuverability. Through-wire control system (Fly-by-Wire) from three-channel redundant system ensures the aerodynamic resistance of the aircraft in flight. Also in emergency situations provided analog system backup management.

Since the aircraft was developed in Sweden, where a limited number of plains, that for this reason, the plane has an excellent takeoff and landing performance, allowing take off and land on short runways. Brake pads with slats provide sufficient aerodynamic braking during landing.

About 30% of the airframe is made of composite materials. The horizontal surface of the wing control, the slats are made of carbon fiber. The fuselage is made of aluminum alloy, an alloy of titanovovogo wings.

Engine JAS-39


The JAS-39 uses the RM12 power plant as the engine. This engine is a turbojet two-loop engine with an afterburner (TRDDF) manufactured by Volvo Aero Corporation. This is a modified version of the engine by the American company General Electric F-404-400, which is used in the American F / A-18. RM12 from F404 features increased traction. 54кН in RM12 against 48,9кН in F404 without forcing and 80,5кН against 78,7кН, respectively, with afterburner. Other differences are greater resistance to ingestion of foreign objects and higher reliability, so that the engine meets the safety criteria for use as one aircraft engine. The engine operation, including automatic traction control, is controlled by a special computer, ensuring maximum engine performance, which makes it possible to adapt to specific conditions with maximum efficiency. The JAS-39C / D uses a modified Volvo Aero RM12UP engine.


Avionics JAS-39


The aircraft is equipped with a pulse Doppler radar PS-05 / A, operating in the frequency range 8-10 GHz. Radiated power 1 kW radar to detect targets up to 120 km. Radar can automatically tracking multiple targets in the upper and lower hemisphere, on land, on water and in the air, and in all weather conditions. It can also simultaneously inducing to 4 missiles "air-air" in the 4 different purposes.

Electronic equipment is characterized by a high degree of integration and automation of many functions, allowing the aircraft to conduct combat operations in all weather conditions, day and night.


Armament JAS-39


The main armament is the 27-mm air gun Mauser BK27 with a rate of fire from 1100 to 1700 shots per minute with a stock of 120 cartridges (not available in the JAS 39B double model). JAS-39 has 8 suspension points and is capable of carrying a combat load of a total weight of 4200 kg. The export version of JAS-39NG has 10 suspension points. The carrying capacity in this version is increased to 5200 kg. In the class of air-to-air missiles, it is capable of carrying to the 6 missiles such as AIM-9 Sidewinder or 4 missiles AIM-120 AMRAAM. In the air-to-surface class, the aircraft is capable of carrying up to the 4 missiles AGM-65 Maverick or to 2 long-range missiles TAURUS KEPD 350 / 150, designed to defeat high-security targets. Also JAS-39 is capable of carrying up to two anti-ship missiles RBS-15, developed by the Swedish firm SAAB Bofors Dynamics.

Bombings armament includes up to 4 guided bombs, laser-guided GBU-12 PAVEWAY II or up to 8 laser-guided bombs without Mark 82. It is also capable of carrying and cluster bombs.

Grippen is in service with the following countries: Sweden, Hungary to 2006 years old, United Kingdom, Czech Republic, Thailand, South Africa to 2007 years
