Sukhoi Su-37 Terminator

The SU-37 Terminator is a Russian Fourth generation Fighter Jet made by Sukhoi Avionics

Description
Su-37 Terminator - multipurpose fighter based at the multipurpose fighter Su-35. A further increase in flight characteristics of the machine was only possible when you install the engine with variable in-flight thrust vectoring. Work in this direction for several years were in the Yakovlev Design Bureau. AM Pipes, and prototype testing conducted in the spring of 1989 T-10-26 Victor Pugachev. Then the plane set up only one engine, the nozzle which is likely to change their position in the vertical plane, for which the pilot switched the toggle switch in the cockpit. To prepare the demo fighter with a deviating thrust vector took one of the Su-35, installed on it, two AL-31FP engine, put in the cockpit side handle control plane and tenzorud (a new kind of handles the engine management). After appropriate modifications control systems and aircraft engines, machine name was changed to Su-37. April 2, 1996 test pilot EDO EI Frolov picked up a plane in the sky, and on 18 August of that year, the Su-37 was first shown at the air show in Tushino in Moscow.

During flight tests of Su-37 has demonstrated the unique maneuvering capabilities. For the first time were worked out new maneuvers associated with access to very large angles of attack and near-zero skorosti.Tehnicheskie solutions implemented in the construction of a new fighter, provided:

the possibility of preemptive strikes against any enemy aircraft (including aircraft and unobtrusive);

multichannel and algorithmic security of all information and sighting systems;

attack ground targets without entering the zone of enemy air defenses;

low-altitude flight with a flyby of the ground and bypass obstacles;

automated group actions on air and ground targets;

resistance radioelektornnym and opto-electronic means;

automation of all phases of flight and combat use.

The plane is made under the "unstable integral triplane", combining normal aerodynamic configuration with canards. The design of the airframe as a whole is similar to the Su-27, but when you create Su-35/37 used new aluminum-lithium alloys, greatly expanded the use of composite materials. For aircraft designed a new wing with increased relative thickness, accommodating a larger volume of fuel.

The horizontal tail is differentially deflected stabilizer, each console has the proper high-speed electro-hydraulic actuator. PGO is included in the total digital-wire flight control system and can vary in the range of angles of -50 / +10 °. In addition to improving stability and controllability at high angles of attack (in particular, Su-35/37 almost completely failed to eliminate shaking, very difficult for piloting and aiming at the fighters of other types of similar modes), PGO carries out a number of other important functions. In particular, it helps shift the focus forward aerodynamic plane, which leads to a significant reduction of static stability.

Through the PGO may "control" the degree of instability of the aircraft, which varies depending on the load on the external nodes of the suspension. When flying at low altitude in the turbulent atmosphere PGO is an active and passive damper longitudinal vibrations and jolts that improves safety, reduces the load on the airframe and increases comfort, and, hence, combat effectiveness of pilot in buffeting conditions. Aerodynamic enhancements applied by plane, allowed to reduce loads on the fuselage and wing root, which, in turn, will permit the achievement of steady overload of 10 units. without amplification of airframe (the maximum steady-overload has been reached on other types of fighters, does not exceed the current 9 units.).

Compared to the Su-27 increased slightly the height and chord vertical tail fighter. Caisson keels, made of carbon fiber are used, as well as fuel tanks. Stoics strengthened chassis (which is due to the increased takeoff weight of aircraft), nose base is equipped with two wheels. Under the wing added two nodes external suspension (the total number brought to 14), which increased the weight of the weapons from 6000 to 8000 kg. Airplane ejection seat equipped with a CD-36DM with seat back angle of 30 °. Compared to the Su-27 increased oxygen supply, installed containers with supplies of food and water, and waste disposal unit.

The prototype Su-37 (known as the board "711") set AL-31FP engines with thrust vector control systems for pitch control. TRDTSF equipped with a digital electronic control system, integrated with the control system aircraft. Axisymmetric controlled nozzle deviates in the vertical plane at an angle of ± 15 ° with two pairs of hydraulic cylinders, fed by hydraulic obschesamoletnoy (angular velocity of the nozzle - 30 ° / s).

Serial Su-37 is planned to fit upgraded engines AL-37FP (2 x 14500kgs), is a further development of AL-31 turbofans. In TRDTSF provide cooling turning the nozzle on full-Forsazh and the maximum angle of rotation. As the working fluid in the hydraulic cylinders used in aviation fuel. Thrust vector control systems can control the aircraft in the plane of the pitch and yaw, is achieved by a mismatch of the direction of thrust of the right and the left engine. The aircraft is equipped with a retractable rod toplivopriemnika system in-flight refueling.

Su-37 is equipped with a digital control system elektrodistantsionnoi (EDSU) plane. It is made by chetyrehkanalnoi an arrangement in the longitudinal channel and trehkanalnoi scheme - in the canals of lateral movement. To increase the reliability of all calculators EDSU working in parallel. Automated control of the aircraft provides all control surfaces, as well as the deviation of the thrust vector engines by moving the control stick plane. At the same flight safety achieved by the automatic constraint overloads aircraft, depending on the flight weight and flight regimes. There is automatic withdrawal from a spin. Installing a new set of airborne equipment with increased power required to increase the power of electricity and gidropitaniya. Compared to the Su-27 set new generators and pumps. At Su-37 is installed side malohodovaya control handle and the stationary strain gauge ORE.

Avionics aircraft include systems that use elements of artificial intelligence and proactively engage air targets (including unobtrusive) at distances guaranteeing the possibility of retaliation of the enemy. Automate all phases of flight, including the combat use of air targets, the attack ground objects without entering the zone of enemy air defenses, resistance to radio-and opto-electronic means of electronic warfare. According to information received from navigatsionnnoy system, ACS solves the problems en route to the programmed flyby of the intermediate points of the route, return to the airfield, prelanding maneuvering and approach to a height of 60m. There is automatic flight control at extremely low altitude, with a bypass or overflights of ground obstacles. An automatic target designation during operations both in air and ground targets.

Su-37 is equipped with a complex, including pulse-Doppler radar with a fixed phased-array radar and rearview. Enhanced optoelectronic sighting system includes a thermal imager fighters, combined with a laser range finder-designator. Provides detection, identification and automatic tracking of multiple aerial targets simultaneously at long range. Optical radar system combined with radar and advanced Helmet sight of the pilot in a single complex. The airplane is Automatic secure data exchange system on order to better coordinate the actions of several fighters, leading a group fight. The complex includes optical sensors defense warning attacking enemy missiles, electronic intelligence station, a new generation, active suppression system operating in the optical and radar ranges, as well as means setting passive radar and IR interference. The Su-37 has a new information-control field cockpit with four large-format color LCD (unlike the Su-35, where inlikatory monochrome) multifunction displays and a wide-angle indicator on the windshield. In the indicators used in liquid crystal matrix. Communication equipment includes radio VHF and HF-band equipment telecode secure communications, and satellite communication system.

Armament includes the traditional fighter for a family of aircraft "Su" gun GSH-301 (30mm). At the 14 sites external suspension may be placed different weapons total weight of 8000 kg. All possible options for more than 70 foreign suspension, including missiles, air-to-air medium-range F-77 with active radar homing missiles for air-to-air medium-range family of R-27 active radar or the passive infrared-guided, highly maneuverable missiles air-to-air short-range F-73 with TGS, missiles X-31 air-to-ship and air-to-radar, missiles, air-to-surface family of X-29, bombs and cluster bombs caliber up to 500kg
