Design
Yak-130 is an advanced pilot training aircraft, able to replicate characteristics of Russian 4th and 5th generation fighters. This is possible through the use of open-architecture digital avionics compliant with a 1553 Databus, a full digital glass cockpit, quadruplex-channel digital Fly-By-Wire System (FBWS) and Instructor controlled and variable FBWS handling characteristics and embedded simulation. The type also has a Head-Up-Display (HUD) and a Helmet-Mounted-Sighting-System (HMSS), with a double GPS/GLONASS receiver updating an Inertial Reference System (IRS) for highly accurate navigation and precision targeting. The developer estimates that the plane can cover up to 80% of the entire pilot flight training program.
In addition to its training role, the aircraft is capable of fulfilling Light Attack and Reconnaissance duties. It can carry a combat load of 3,000 kilograms (6,600 pounds), consisting of various guided and un-guided weapons, auxiliary fuel tanks and electronic pods. According to its chief designer Konstantin Popovich, during a testing phase that ended in December 2009, the plane was tested with "all airborne weapons with a weight of up to 500 kg that are in service in the Russian Air Force". Yak-130 has nine hard points: two wingtip, six under-wing and one under-fuselage.
The aircraft's twin engines are mounted under extended wing roots, which reach as far forward as the windscreen. Two Ivchenko Progress AI-222-25 Full Authority Digital Engine Control (FADEC) produce a combined total of 49 kilonewtons (11,000 pound-force) of thrust. An upgraded, "-28" engine is also on offer, increasing the thrust to 53 kN (12,000 lbf). At a normal Take-Off Weight of 7,250 kg (16,000 lb), a Thrust-to-Weight ratio of 0.70 is achieved with the "-25", or 0.77 with the "-28" engines. This compares with 0.65 for the BAE Systems Hawk 128 and 0.49 for the Aero Vodochody L-159B.
Maximum internal fuel capacity is 1,700 kg (3,700 lb). With two external combat fuel tanks the figure increases to 2,600 kg (5,700 lb). Maximum true airspeed is Mach 0.93 (572 knots), service ceiling is 12,500 metres (41,000 feet) and load factors are from -3 to +9 g. Typical Take-Off speed and distance in a "clean" configuration are 209 km/h (113 kn) and 550 m (1,800 ft), whilst landing figures are 191 km/h (103 kn) and 750 m (2,460 ft), respectively. Cross wind limit is 56 km/h (30 kn).
The Yakovlev Yak-130 is equipped with the FBWS controlled engine intake blanking doors, in order to prevent the aircraft's engines from sustaining Foreign Object Damage when operating from unpaved runways and grass strips.
The large canopies are sideways hinged.
Combat training suite on the Yak-130 includes simulated and real firing systems with air-to-air and air-to-surface missiles, bomb dropping, gun firing and on-board self-protection systems. The instructor can set and control "target behavior" from his seat in the aircraft. It has an automated on-board diagnostics and control system which makes the aircraft easy to operate and maintain. It has an improved airframe with a design lifetime of 10,000 flight hours and 20,000 flight cycles during a calendar lifetime of 30 years and can operate from unpaved airfields.

Famous quotes containing the word design:
“I begin with a design for a hearse.
For Christ’s sake not black—
nor white either—and not polished!
Let it be weathered—like a farm wagon—”
—William Carlos Williams (1883–1963)
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
“I always consider the settlement of America with reverence and wonder, as the opening of a grand scene and design in providence, for the illumination of the ignorant and the emancipation of the slavish part of mankind all over the earth.”
—John Adams (1735–1826)
