【文章內(nèi)容簡介】 tial navigation system, navigation puter, and so on. Second generation fighter with all weather operation capability, equipped with mediumrange airtoair missile, and balanced ground attack, attack ability. Second generation fighters airborne electronic equipment and large improvements in the performance of weapons systems, heavy tendency clear of the aircraft. 三代機 第三代 ? 美國、前蘇聯(lián)等國在上世紀(jì)“越戰(zhàn)”之后開始研制第三代噴氣戰(zhàn)斗機。它的重點是強調(diào)格斗空戰(zhàn)能力和全天候作戰(zhàn)能力；重視飛機在亞、跨音速范圍內(nèi)的機動性；機載航電和武器系統(tǒng)的性能水平有了突破性進展。從實戰(zhàn)結(jié)果看，第三代戰(zhàn)斗機研制比較成功。這首先是由于設(shè)計師們們正確總結(jié)實戰(zhàn)經(jīng)驗教訓(xùn)，調(diào)整了戰(zhàn)機設(shè)計理念；其次是由于 20世紀(jì) 60年代末至 70年代初，航空科技在氣動理論、動力裝置、電子技術(shù)、機載武器、新型材料等方面的發(fā)展迅速，為戰(zhàn)斗機的研發(fā)創(chuàng)造了良好的條件。代表機型有： F1 F1蘇 2米格 29和殲 殲 11等。 ? United States, the former Soviet Union and other countries in the last century, the Vietnam war starts after the development of the third generation jet fighters. Its focus is on the representation of fighter dogfight bat capability and operational capacity around the clock。 importance of aircraft in Asia, mobility within the transonic range。 airborne avionics and weapon system39。s performance level has made progress. From the perspective of practical results, the thirdgeneration fighter development of the more successful. First of all, because the designers were correctly summing up the experience and lessons learned, adjusted the fighter design philosophy。 and secondly because early in the late 1960 of the 20th century, aviation theory, power plant technology in pneumatic, electronic technology, airborne weapons, new materials and other aspects of the rapid development of fighters has created good conditions for research and development. Representative models are: F15, F16, Su27, MiG29 and the Jian10, fighter, such as 11. ? 特點：具有高的機動性，要求飛機推重比（發(fā)動機推力 /飛機重量）大于 ，以往的戰(zhàn)斗機推重比均小為此要采用大量先進技術(shù)，特別是發(fā)動機的推重比（發(fā)動機推力 /發(fā)動機重量）要達到 。飛機能垂直上升，飛機的最大飛行 M=～ ，巡航 M=，作戰(zhàn)半徑 =800～ 2023km ? Features: high mobility requirements aircraft thrustweight ratio (engine thrust/weight) is greater than 1, fighter thrustweight ratio is smaller in the past through the use of a large number of advanced technologies, in particular the engine thrustweight ratio (engine thrust/weight of the engine) to reach 8. Aircraft vertical upward, the aircraft39。s maximum flight M=~ cruise M=, bat radius =800~2023km F16“戰(zhàn)隼” F15“鷹” 蘇 27“側(cè)衛(wèi)” 蘇 30 殲 10“猛龍” 米格 29“支點” FC1“梟龍” jas鷹獅 幻影 2023 蘇 35 四代機 第四代 ? 第四代戰(zhàn)斗機是目前正在研制的最先進的戰(zhàn)斗機，它的技術(shù)戰(zhàn)術(shù)指標(biāo)是根據(jù)現(xiàn)代高技術(shù)局部戰(zhàn)爭的實戰(zhàn)經(jīng)驗提出的。現(xiàn)代戰(zhàn)爭已經(jīng)由過去的單一兵器的對抗轉(zhuǎn)變?yōu)楹！㈥?、空軍三位一體全方位的較量，而其中最重要的則是制空權(quán)的爭奪。 ? 如美國的 F2 F35，俄羅斯的 蘇 20以及殲 31等。主要特點是具有突出的隱身性能、超音速巡航能力、超常規(guī)機動性和敏捷性、短起降能力（或全環(huán)境作戰(zhàn)能力），簡稱 4S。采用推重比 10一級的渦扇發(fā)動機、相控陣火控雷達、隱身技術(shù)和推力矢量技術(shù)等，以“發(fā)射后不管”空空導(dǎo)彈為主要武器。 ?
