In this paper, firstly the macro parameter of the series connection app was comprehensively analyzed, among which the trajectory location of the bullet emission and the terminal velocity of the bullet were mainly analyzed, and the feasibility of the series connection app to cope with explosive reactive armor was demonstrated. and then the macro design about the head of the series connection app was made, among which a particular analyse about the bullet " s launching process was made, from which we concluded the relation between the thickness of the airproof loop and the velocity of the bullet detached from the carrier and the relation between the length of the bullet and the velocity of the bullet detached from the carrier and the relation between the length of the bullet and the burning rate of the powder and the relation between the length of the bullet and the maximum pressure of the emission hole and the relation between the length of the bullet and the emitting time of the bullet, and the reasonable str ucture of the head of the carrier and bullet were designed, then the intensity of the head of the carrier was checked out using of the software of ansys
本文首先對子母式穿甲彈總體參量作了全面的計算分析,其中主要分析了子彈射出的彈道位置和必要的子彈著靶速度,論證了子母式穿甲彈對付爆炸式反應裝甲的可行性,然後對子母式穿甲彈彈頭部進行了總體設計,其中主要對子彈的發射過程進行了詳細的分析,得出了母彈彈頭部發射孔內閉鎖環厚度與子彈飛離母彈速度的關系、子彈長度與子彈飛離母彈速度的關系、子彈長度與火藥燃燒率的關系、子彈長度與母彈彈頭部發射孔內最大壓力的關系以及子彈的長度與子彈發射所需時間的關系,設計出了合理的母彈彈頭部結構和子彈的結構,並利用ansys有限元分析軟體對母彈彈頭部的強度進行了校核。Second, by computing the trajectory of the missile and the method of analyzing cep, influences that the fighter ' s height, speed, pitch angle, the deflection angle between fighter and target, and the target moving characters make on the times of fighter attack and missile launch are deeply developed. third, by relating the motion of the missile and the fighter, the influences that fighter ' s dive angle and the deflection angle between fighter and target make on the attack field of the fighter are discussed in this paper when the fighter perform vertical and horizontal attack. criterion of attack effect is proposed focusing on attack time of the fighter, trajectory of the missile and destruction probability to the target
本文主要完成了以下幾個方面的工作:對導彈可發射區和飛機可攻擊區進行建模,通過對導彈彈道的模擬計算,並運用典型的圓概率偏差精度分析方法,詳細討論了飛機實施攻擊時,飛機的飛行高度h 、速度v 、俯仰角、與目標的偏離角_ x及目標運動特性等對飛機攻擊時機和導彈發射時機的影響;因此,將飛機和導彈結合起來,詳細研究了飛機在垂直平面和水平平面內實施攻擊時,飛機俯沖角和與目標的偏離角_ x對飛機的攻擊范圍的影響;以飛機實施攻擊的時間t 、彈道特性和對目標的殺傷概率p來評判對地攻擊的效果;最後給出典型算例,通過對空地攻擊過程的模擬實現,對飛機飛行過載提出要求。This paper presents a wider research field - risk analysis. through the study of the effects that threat factors and error factors impact on the flight risk and adjusting performance rules, the horizontal safe corridor, threat avoidance, vertical altitude real - time modification and the fastest trajectory programming are progressed
總結前人在該方面的研究成果,提出一個更加廣義的研究角度? ?風險分析。通過對威脅因素、誤差因素對飛行風險的作用,調整性能準則而進行了水平安全走廊設計、威脅迴避、垂直離地高度實時修正以及最快速航跡規劃。Improvements in performance include reductions in specific fuel consumption ( 4 % ), take - off distance ( 10 - 20 % ), minimum speed ( 100 kias ), time to climb and increase in specific excess power, sustained load factor and sustained turn rate ( 15 % )
性能改進方面包括減少4 %的耗油率,縮短10到20 %的起飛距離,減少最低速度大約一百指示空速節,縮短爬升時間和增加單位剩餘功率,提升15 %的持續回轉率與持續負載系數。An on - line minimum - variance estimator was developed for thrust acceleration applied to orbit transfer using discrete - time radar measurements. the mass - flow - rate of propellant was selected as a state variant, which was estimated by employing an integral state model and ekf filter. the variation equations for measurement vector to mass - flow - rate have been established to linearize the discrete - time measurement equations. the algorithm has applied successfully to maneuver process in commanding satellite into geo - stationary orbit. the results show that the algorithm developed here can monitor and determine whether engine works well or failure precisely and quickly during orbit transfer process
飛行器軌道機動過程中,為跟蹤、定位機動目標和干預機動控制過程,需要統計處理離散的雷達觀測量實時估計推進發動機的推力,進而確定飛行器的瞬時軌道參數.本文所述演算法是該工程問題的探討和解決方案.文章建立了軌道機動過程中連續變質量運動模型和離散雷達量測模型,推進發動機的質量秒耗量作為表徵推力加速度的一個近似常量,應用擴展卡爾曼濾波對離散的雷達測量數據進行順序統計處理給出秒耗量的最小方差估計;文章詳細地推導了線性化量測模型的變分方程和觀測矩陣;模擬結果表明該演算法能快速、準確地估計推進發動機的質量秒耗量和向機動目標施加的實際推力The locomotive, which was slowly approaching with deafening whistles, was that which, having been detached from the train, had continued its route with such terrific rapidity, carrying off the unconscious engineer and stoker. it had run several miles, when, the fire becoming low for want of fuel, the steam had slackened ; and it had finally stopped an hour after, some twenty miles beyond fort kearney
它自從甩掉了列車以後,就以驚人的速度帶著半死不活的司機和司爐繼續向前飛馳,一直跑了好多英里,一小時之後煤燒得差不多了,火也小了,蒸氣也減少了,它才越走越慢,最後在離開克爾尼堡二十英里的路上停了下來。The faster an object moves, the greater difference it has between real existence and result of observation. deflection of space - time allows us to know the difference. when the airship is stationary, we say the real length of the ruler is the same as its measured length, however as long as the airship leaves the earth with a high speed, we can find there is error between its real length and measured length
我們還以飛船上的尺子為例,當飛船與地球相對靜止時,我們說這兩把尺子等長,尺子的真正的長度與我們看到的長度是相等的,但當飛船飛離地球時我們會發現,在飛船上的尺子的真正長度與我們所看到的尺子的長度有誤差,而且隨飛船速度的增加,這一誤差會越來越大。分享友人
