For studying the performance of solid rocket ramjet under the influence of different flight conditions , it ' s significant to simulate the integrated flow field of inlet and combustor 因此,开展超声速进气道/补燃室流场一体化数值模拟研究对于考查飞行状态对于火箭冲压发动机性能的直接影响具有重要的现实意义。
Fm sweeping and interpulse intervocal ranging from 23 . 6 ms to 443 . 8ms . myotis capaccinii use echolocation calls with short duration , long interpulse intervocal , wide fm sweeping and low duty cycle 6种蝙蝠飞行状态下的回声定位声波均为fm型，一般包括1 3个谐波，能量多集中于第1谐波，第2谐波和第3谐波较弱。
For the convenience of the design and experiment of cpcs , a sapc ( simulated atmospheric pressure cabin ) that can simulate the atmospheric situation when aircraft are at different flight states was necessary 座舱压力控制系统的研制和检验过程中,需要大气压力模拟舱,其主要功能是模拟飞行器各种飞行状态下所处大气压力环境。
The simulated estimation indicated that this observer not only have high estimated precise in kinds of maneuvering fly , but also have good robustness to atmosphere turbulence or the change of flight stat 经过理论分析和仿真验证，这种观测器不仅在各种机动飞行下具有很好的估计精度，而且具有很好的抗大气紊流干扰及飞行状态变化的鲁棒性。
Compared with non - slung - load flight , additional aerodynamic load , gravity load should be considered in the slung - load system . so the moment to the gravity center , flight mode and the natural frequency will change 直升机吊挂飞行,与直升机非吊挂飞行状态相比,增加了新的气动载荷、重力载荷,和因此产生的对直升机重心的力矩,其飞行运动模式、低频振荡固有频率均发生改变。
In order to determination the thrust , the thrust definition and many control parameters are analyzed discussed , which mass flow rate and flight altitude are involved . it is difficult to measure the flight thrust of solid rocket ramjet directly 通过讨论高空飞行推力与地面可测试参数的关系，得到了固体火箭冲压发动机高空飞行状态下推力折算方法，并开发相应的计算程序。
A couple statements i want to make before we open it up is , one , contrary to some releases , this aircraft was straight and steady , holding altitude , heading away from hainan island on auto - pilot when the accident occurred 在我们接受提问之前我想作两点声明，一，与一些报导所说的相反，在事故发生的时候，这架飞机是在直线平稳飞行，高度固定，处于自动驾驶飞行状态，向背离海南岛的方向飞行。
" the cnsatm has immense benefits in enabling aircraft to operate more frequently within their most optimum flight envelop , while minimising airspace constraints , and reducing traffic congestion . it also commensurates with achieving a marked increase in flight safety 该系统不但能容让航机在最佳的飞行状态范围增加飞行次数，把空域限制减至最少，纾缓航空交通挤塞，而且更可显著提高飞行安全。
This thesis ’ research goal is carrying on the simulation using the view simulation technology to the missile launch process , so we can both simulate the missile ’ s flight trajectory and blast effect real time , and reappear the entire testing process after experiment 本文的研究目的就是利用视景仿真技术对导弹的发射过程进行仿真,做到既可以实时地监控导弹的飞行状态,又可以在试后直观地重现整个试验过程。
