J125T "TENRAI" ( 天 雷"Heavenly Thunder" ) first entered service in 1984 during the great anti-communist war known as "The Red Monsoon". During said conflict, various Nifonese aircraft found themsleves underperforming against the cheap Wenchuani copies of old soviet MiG moodels. Designed purely as interceptors, 3rd generation aircraft were engaged at close range where Mig's capability of near instant turn put them at a serious disadvantage.
The Tenrai project was a brainchild of Col. Arata Shosuke, a decorated Nifonese fighter ace. After having been rendered unable to fight due to being shot down, col. Shosouke was employed as a consultant by Tsukumo Heavy Industries. There he laid project of a versatile aircraft built around maximizing trust and wing loading. His proposal won the navy's new fighter contest, and soon was accepted by the Air Arm too.
In the later years of the red moonsoon initial versions of Tenrai rose to acheive 7 to 1 kill ratio against Wenchuani air force. The aircraft has been developed by the Nifonese ever since, with the fifth upgrade Tenrai - Ne, being offered here.
Design:
- The aircraft is divided into three sections: pilot compartment at the front, fighting compartment in the middle and engine compartment at the rear.
- Tenrai follows a conventional design featuring a blended wing body, with a pair of canards mounted at the front, mid- mounted, swept back wings, and horizontal stabilizers. Two large canted vertical stabilizers decorate the rear of the fighter. Wing's trailing edge features manoeuvring flaps and wing tip ailerons responsible for control.
- A small canards were included to provide post-stall control and to eliminate buffeting at high angles of attack and allowed the airframe to sustain manoeuvres in vicinity of 10G. J125T is also a relaxed stability design allowing it to perform complex manoeuvrers like Pugachev's cobra or J-turn.
- Semi-circular air intakes similar to those found on Mirage 2000.
- The wings feature broad, continuos leading edge extensions.
- Dual air brake.
- Despite considerable size, A125T is light in terms of weight which was achieved by using durable, yet light materials such as carbon fiber, aluminum - lithium or aluminum - titanium alloy to build majority of it's hull.
- Refuelling probe to the right of the cockpit allowing for mid-air refuelling.
- Unlike earlier variants J125T features a fully digital, glass cockpit. " cockpit features three liquid crystal displays; one to the right portraying aircraft status, emissions and electronic warfare; while the one to the left acts as a fire control system. Steering is accomplished through a single centrally mounted joystick argumented by fly by wire system.
Propulsion:
- Propulsion is provided by twin Kojima K135 afterburning turbofan engines, each providing 80 kN kN dry trust and 134 kN trust with afterburner. K135 features 3D trust vectoring allowing it to deflect its nozzle to a maximum of ±15° at a rate of 30°/sec. This technology is primarily used in post-stall situations.
- 6 300 kg of fuel can be carried internally. In addition to that underwing fuel tanks can be included.
Avionics:
- Main sensor of this fighter is a Ta - ki 48 radar - a solid-state, active electronically scanned array (AESA) radar composed of 1956 transmit/receive modules, generating peak power of 20 kW. It is capable of tracking 62 targets and attacking 16 simultaneously, guiding 8 missiles at once with horizontal scan area of 180* and estimated vertical scan area of 55*. 4 targets can be simultaneously engaged on the ground. Maximum scanning area is 400 km with narrow pulse and 250km with wide pulse.
- Two flank arrays of L-band radars were incorporated in the wings. Those arrays give the pilot more complete views, increase anti-stealth capabilities and can be used not only for target detection, but for EW and IFF also. Their drawback is a poor resolution and limited range of 150 km.
- J125T features advanced display core processor capable of processing 87 billion instructions per second, granting "Tenrai" data fusion capability on par with fifth generation aircraft.
- Tenrai includes state of the art Washi Wa-17 strapdown inertial navigation system built around three laser gyroscopes and three quartz accelerometers.
- Additional capabilities are supported by Multifunctional Information Distribution System (MIDS), allowing for quicker data exchange. All sensor systems aboard Tenrai are directly integrated with aircraft's VHF - UHF link to support sharing of information between aircraft.
- To properly guide the missiles, Tsukumo's aircraft uses To - Ga helmet mounted display, providing 20* FoV for the pilot's right eye and fully capable of displaying every data from the aircraft's own sensors, alongside electromagnetic position sensing technology employed.
- To further add to it's sensor capability, a Washi 15 - 87 - 9 optronic system was mounted on the aircraft. Linked to helmet mounted display, Washi 15 - 87 - 9 features Washi - 15 IRST mounted to the left that operates within spectrum of 3–5 and 8–11 micrometers and is fully capable of detecting air targets at range of 100km and surface targets at range of 6km, while to the right is a TV/IR system with up to 40km range used for purpose of target identification.
- All electronic support measures (ESM), radar warning receivers (RWR) and electronic warfare (EW) functions were connected to a single system called "Kozane-2" after first type of lamellar armour worn by the Nifonese samurai, aimed at increasing survival ability of the aircraft, created from earlier "Kozane-1" mounted on lighter fighters. "Kozane" family series is specifically optimized for aircraft it is placed on, due to open-end architecture allowing it to integrate various systems depending on requirements placed on it. "Kozane-2" integrates as well fighter's powerful AESA radar to be used for electronic warfare functions.
- Washi 3-17 Radar warning receiver. Possessing over 30 antennas that have been blended into the fuselage and wings and with range reaching up to 500km, A125T pilot can quickly react to any surprise attack by any possible foe. The system can automatically inform pilot to release countermeasures and can be used for passive detection and targeting of hostile forces. It allows as well the emissions to be reduced to narrow beam (2*/2* in azimuth/elevation). Washi 3-17 can as well be used to passively target enemy combatants.
- Washi 4-15 laser warning receiver was designed to counter emergent threat by laser - guided missiles (SACLOS). The system automatically detects laser beam and informs the pilot, including direction from which the beam is being emitted.
- Washi 5-11 missile approach warning system (MAWS) consists of 4 sensors and electronic control unit (ECU), using ultra violet signature emitted by the missile engine for detection of hostile missile attacks. Each unit has 110* field of view. The sensor is fully passive, and the false alarm rate has been proven to be low due to incorporation of advanced system of pattern recognition algorithms that operate on defined wavelengths. Once a hostile missile is detected, Washi 5-11 provides full range of information such as attitude, speed and positioning, allowing for better discernment of errors from true attacks.
- Another important countermeasure is "SML" countermeasures disperser, capable of dispersing chaff and IR countermeasures, housing over 160 packs of various kinds. Release occurs via non-pyrotechnic mechanism using electromagnetism to push the countermeasures weighting from 7 kg to 9 kg depending on type into the airstream. Fully integrated with internal avionics, two such packs were mounted at both wings. New generation of materials allowed to create an extremely effective countermeasure system which, when coupled with extreme manoeuvrability and jamming, allow to successfully evade attack by newest missiles.
- Washi W-21 are pair of wing-tip pods especially designed to provide self defense electronic warfare capability by using digital radio frequency memory (DFRM) jamming. "W-21" is capable of jamming targets between 6 GHz to 18 GHz spectrum, +/- 90 degree in azimuth and +/- 60 degree in altitude around the aircraft with power of 50 Watt per module.
- Fujita Type F-12 is a towed decoy designed to, rather than than traditional decoys, work directly integrated with aircraft's own EW systems. Towed on a fiber optic cable of length up to 100 meters, F-12 has a conversion device that converts the data into light to be transported and analyzed by main EW unit inboard the fighter. F-12 can work in variety of modes including deception, suppression and seduction of enemy missiles.
- "Tenrai" started purely as an air superiority fighter, however growing requirements caused inclusion of new air to ground capabilities via optional pylon mounted "Horo" targeting pod which incorporates it's own FLIR, HDTV, laser spot tracker, laser marker, video data link, and a digital data recorder, capable of guiding bombs even through smoke and clouds and with low - light / no - light conditions.
Armaments:
- 12 hardpoints, 6 under wing, 6 under the fuselage.
- Aside from rockets this plane can count on a single Ryu-92 gattling gun. Ryu-92 is a six barrelled rifled gattling gun shooting 23x115 rounds. Being one of cannons possessing the highest rate of fire in the world, Ryu-92 is gas-operated (requiring no external power source to operate, reloading itself by recoil of the floating barrels) and fed by linkless feed system, with electrical fire control (this new computer-managed system allows the pilot to manage the size of the salvos) and 10 pyrotechnic cocking charges. While it can not match the sustained rate of fire of electric-powered gattling guns, the initial rate of fire of Ryu-92 is far higher. The gun is capable of shooting up to almost 8 500 rounds per minute, which permits it to rip to shreds any target unlucky enough to find itself within it's range. 500 rounds of ammunition are carried, allowing Ohka expend it's ammunition in less than 2 sec, turning whatever the target into a Swiss cheese.
