Machine of intercept of Su Huoyi Su-15, north makes an appointment with "(Flagon) of bottle of fine mouth of code name " , it is machine of intercept of a when Russia begins to enlist in army from 1967 double engine, in order to replaces the Su-11 intercept machine that enlists in army at that time. Revive - 15 be before the round-the-clock intercept machine that the first kind of function perfects Russia quite, use compound triangle limb (archetypal machine is pure triangle ala) , two side enter pointed nose angry total position, give attention to two or morethings low speed and the need that high speed flies, in the airframe of stabilizer ahead at the same time two side contain two decelerate board, use in sky to reach ground decelerate. Pilot: 21.4 meters, machine is expensive: 5.0 rice, the ala is exhibited: 10.53 meters, wing area: 37.2 square metre. Empty weight: 11.34 tons. The biggest heavy: 18.14 tons. Cruise speed per hour: 980 kilometers, the biggest speed per hour: 2540 kilometers, fight radius: 725 kilometers. Turn a range: 1500 kilometers, practical ceiling: 20000 meters, the biggest climb is led: 225 meters / second, take off slippery run distance: 800 meters. Machine of double-barreled of a 23 millimeter prepares Chinese medicine by roasting it in a pan, play 200 hair fully. Outside 4 next commonage, wing registers a drop, can hang " of cloth of accept of outfit AA-3" A infra-red control and guide or sky of radar control and guide are right infra-red control and guide of " of aphid of empty missile, " is apart from nearly sky is right weapon of empty missile, other or auxiliary tank. Dynamical system 2 P-13 Ф - 300 turbine reaction engine, the biggest thrust makes an appointment with only station 40 1000 oxen, thrust augmentation thrust is 70 1000 oxen. Plane hold in esteem is compared big, alar load is smaller, have better flight and motor-driven property. With the west congener plane photograph is compared, its defect is range shorter, electronic equipment is not perfect, cockpit eyeshot is poorer, inchoate model do not prepare Chinese medicine by roasting it in a pan without outfit machine. Mixed 1978 1983, before of Russia revive - the civil aviaton plane that 15 battleplan once atttacked Korea twice, caused casualties the serious accident of nearly 300 people, On July 18, 1981, an Iran (also have saying is Argentina) CL-44 small plane in the sky enters Gelujiya from Iran, defend air man revive - 15 act under orders intercept, requirement crash not after fruit, revive - 15 inbreak the airlines bumped to come down, air man parachute survives. Revive - 15 also because of this " notorious " . Revive - all respects do not accord with the army to ask the function of 15. The mission that plane modernization plans should improve the problem of existence namely. In a few files at that time, improved plane name is " the 2nd Dai Su - 15" . The decision changed airborne radar of " eagle " in March 1968 for radar of " typhoon " . Does modernization change his costume or dress is cent two phase: ? Show off calls out?R-98 of envy of instrument of steel of  of  of  of cover with a straw mat of awl danger  to experiment integratedly at referring a country in November 1968; the 2nd phase, 1969 the 3rd quarter, the R-98M that plane along with already improved refers a country to experiment integratedly. Finished at the beginning of September 1968 revive - the design draft of 15T, plan to install R-13-300 engine on the plane, and perfect electric power and hydraulic pressure system. Of the 2nd phase revive - 15 went up to install system of new R-832M radio, wireless feed to wait at the same time. On January 4, 1969 early morning, base is machined after improved plane carried test-fly is mixed. Seventies evening, revive - 15 be before the machine with Russia confidential height is planted one of, configure only in Russia mainland, did not garrison China make an appointment with other country, also did not export. Su-15 is after cold war end, retire at defending air man from Russia in the round 1993.
