摘要介紹了在滿足高超音速再入橫向機動航程,高超音速再入飛行時的升阻比,亞音速進場飛行時的升阻比,縱向靜穩定性裕度和水平著陸速度等飛行性能設計要求下,用罰函數法尋求使航天飛機機翼質量為最小的外形優化方法並給出了算例。In the range of flight mach number mo = 3 ~ 7, in order to take the advantage of ramjet and scramjet, a fix - shaped dual - mode scramjet, in which both subsonic and supersonic combustion can be obtained, is used for hypersonic vehicle
在飛行馬赫數m _ = 3 - 7的范圍內,為充分發揮沖壓發動機的性能優勢,高超聲速飛行器採用了既能在亞聲速燃燒模態,又能在超聲速燃燒模態下工作的固定幾何形狀的雙模態沖壓發動機。Both advantages of rocket engine and air - breathing engine are integrated into one kind of propulsion system, called rocket - based - combined - cycle ( rbcc ), which has multiple operating woke modes, including ejecting, subsonic combustion, supersonic combustion and rocket mode, with each mode operating at varying flying stage. rbcc has prominent potential of high efficiency and low cost, and so it is recognized as an advanced propulsion system of future single - stage - to - orbit reusable spacecraft and hipper - sonic missile. it has been broadly investigated in foreign countries and has been progressed into small and full - scale flying stage
火箭基組合動力循環( rbcc , rocketbasedcombinedcycle )將傳統的火箭發動機和吸氣式發動機的優點集中組合到一個具有多種工作模態(包括引射、亞燃、超燃及火箭模態)的發動機里,在不同的飛行階段啟用不同的工作模態,因此具有大幅提高航天推進系統經濟性與高效性的潛在優勢,並可能發展成為下一代單級可重復使用航天器以及高超聲速導彈武器的動力系統。Ramjet has been widely used in all kinds of supersonic and high - supersonic aircraft. it has caught more and more attention recently because there is no need for rotating impeller machine
而沖壓發動機不需轉動的葉輪機械,結構簡單,高速性能優良,被廣泛用於各類超音速和高超音速飛行器,愈來愈受到人們的關注。And when extreme agility is required, the limiting factor on an aircraft ' s performance is often the need to keep the pilot alive and conscious under high g - forces
此外,當超凡的敏捷度成為當務之急時,飛機性能的局限因素則通常是需要在高強度的地心引力下讓飛行員生存下來並保持清醒。Dsp56f805 samples the ultrasonic pulse coming back from the target, then measures the distance and shows it on led. tms320vc5509a is accomplished the detecting speed and the main control of the radar system, is 16 fixed dsp with high performance and low power produced by ti company. dsp5509a samples the wave coming from t / r module, then measures the target ’ s speed and send this information to the assistant control chip - p89v51 based on boost c51 core mcs produced by philips company, which controls the lcd
