“…The purpose of this paper is to obtain its aerodynamic characteristics and determine the control ability of the grid rudder. At the same time, according to the American test of QuickReach [2], during the control process, due to the attenuation of velocity in horizontal direction and gravity acceleration in vertical direction, the velocity value attenuation of incoming flow is limited. And the compound control method of grid rudder and RCS is different from the control method of stable umbrella of QuickReach, and the attenuation of horizontal velocity will be less theoretically, so the flow velocity value can be regarded as a constant value in the future.…”

“…Therefore, it is of great significance to choose a suitable and effective attitude control method for the design and research of the rocket in the air. At present, there are several methods of pre-launch attitude control, such as the stable umbrella control method for American QuickReach [2],control method of "stable umbrella + CES" put forward by Japan [3] and RCS control method put forward by Northwest University of Technology [4], etc.…”

The pre-launch attitude control has an important influence on the success rate of rocket ignition and the precision of orbit. In order to realize the composite control method of direct force and aerodynamic force, based on the analysis of the advantages of grid rudder control, the layout design and rudder profile selection are carried out, and the role of grid rudder in the composite control of pre-launch attitude is analyzed. At the same time, the grid rudder is modeled and aerodynamic characteristic analyzed by SolidWorks, and the simulation data are processed and analyzed, so the control ability of the grid rudder is fully understood, and the feasibility of the compound control method is verified.

To ensure the security of the entire air-launched carrier rockets system is an important issue in the research work. As the most expensive part of the system, the numerical simulation of the dynamic characteristics of the aircraft plays an important role. Dynamic equations of aircraft and its cargo during flight are derived in detail and dynamic models are established in accordance to the basic principles of theoretical mechanics and flight dynamics. The dynamic models are then utilized for the simulation of the process of the system. By comparing the simulation results and the real flight test measurements, the models are verified to be correct and precise. The dynamic characteristic of the aircraft under various conditions is also analyzed.

“…В настоящее время для запуска ракет-носителей (РН) с космическими аппаратами активно разрабатываются проекты воздушных стартовых комплексов [1][2][3][4]. Среди существующих схем запуска РН из самолета-носителя (СН) наиболее эффективна схема воздушного старта из грузового отсека (ВСГО) СН [1,5]. Одной из важнейших задач анализа динамики ВСГО по такой схеме является обеспечение безопасного десантирования РН, особенно при использовании пилотируемого СН.…”

“…Экспериментальные данные показывают [1], что при проектировании систем с ВСГО без оценки влияния нестационарных аэродинамических нагрузок, вызываемых вихревым движением воздуха в спутном следе за СН, результаты расчетов динамики процесса десантирования могут оказаться некорректными или даже принципиально неверными. Особенно это касается учета случайного характера нагрузок, которые всегда возникают при взаимодействии тела с завихренным потоком.…”

Рассмотрена проблема безопасного десантирования ракеты космического назначения из фюзеляжа транспортного самолета в пространственный поток несжимаемой среды при воздушном старте. Исследовано влияние стохастических характеристик спутного следа за самолетом-носителем на динамику процесса десантирования. Решена сопряженная задача аэроупругости, нестационарные аэродинамические нагрузки определены методом вихревых элементов. Методом стохастического анализа при умеренной загрузке ресурсов машины получены границы областей разброса кинематических параметров движения ракеты: линейных и угловых перемещений. Вероятность попадания в эти границы соответствует практически достоверному событию. Результаты численного моделирования показали, что случайный разброс начального состояния спутного следа дает существенную ширину границ области разброса кинематических параметров движения ракеты не только в плоскости тангажа, но и в плоскости рыскания. Ключевые слова: воздушный старт, аэроупругость, метод вихревых элементов, динамика конструкций, стохастический анализ.
