12017-07-12. SSTL продемонстрировала видео со своего экспериментального аппарата.
Компания SSTL продемонстрировала видеоряд, который был снят космическим аппаратом CARBONITE-1. Целью демонстрации являлась реклама возможностей компании по бустрому проектированию и сборке космических аппаратов ДЗЗ (срок создания КА составил 6 месяцев). В компании также отметили, что аппарат работает на несколько более высокой орбите чем планировалось изначально, а следовательно компания получила дополнительные возможности по тестированию как оптической системы так и Х диапазонной линии связи. Масса спутника составляет более 50 кг.Тэги: SSTLCBNT 1
22017-11-08. Военное ведомство Великобритании обнародовало свои планы.
На проходящей ежегодной конференции Global Milsatcom, официальные представители министерства обороны Великобритании сделали ряд заявлений из которых следует, что:
1. Стоимость проекта по созданию КА серии Skynet 6 будет составлять около $8 млрд и он будет иметь протяженность более 20 лет.
2. Военное ведомство страны рассчитывает на то, что новая группировка КА геостационарной связи позволит не только увеличить скорость передачи информации, но и привнесет ряд новшеств в существующие бизнес-модели по коммерциализации орбитального ресурса.
3. Первый запуск КА нового поколения состоится в середине 2025 года. При этом текущий контракт с Airbus по поддержанию существующей группировки в работоспособном состоянии истекает в 2022 году.
4. Министерство обороны подтвердило информацию о том, что оно владеет 60 процентами запущенного в 2015 году спутника Carbonite-1 (CBNT 1), однако до сих пор не понимает что он ему дает. Тэги: ВеликобританияСерия Skynet 6Серия Skynet 5CBNT 1

Second-order Godunov-type scheme for reactive flow calculations on moving meshes Boris N. Azarenok a, Tao Tang b a Computing b Department Center of Russian Academy of Sciences, Vavilov str. 40, GSP-1, Moscow, 119991, Russia of Mathematics, The Hong Kong Baptist University, Kowloon Tong, Hong Kong Abstract The method of calculating the system of gas dynamics equations coupled with the chemical reaction equation is considered. The flow parameters are updated in whole without splitting the system into a hydrodynamical part and an ODE part. The numerical algorithm is based on the Godunov’s scheme on deforming meshes with some modification to increase the scheme-order in time and space. The variational approach is applied to generate the moving adaptive mesh. At every time step the functional of smoothness, written on the graph of the control function, is minimized. The grid-lines are condensed in the vicinity of the main solution singularities, e.g. precursor shock, fire zones, intensive transverse shocks, and slip lines, which allows resolving a fine structure of the reaction domain. The numerical examples relating to the Chapman-Jouguet detonation and unstable overdriven detonation are considered in both one and two space dimensions. Key words: Moving mesh, Detonation wave, Reactive flow, Second-order Godunov-type scheme 1 Introduction Modeling detonation wave motion in gases has started in 1940s, see, e.g., [59,26]. The study has been based on the theory of steady one-dimensional detonation, referred to as Email addresses: azarenok@ccas.ru (Boris N. Azarenok), ttang@math.hkbu.edu.hk (Tao Tang). Preprint submitted to Journal of Computational Physics 16 December 2004 the Zeldovich-Neuman-Doering (ZND) model. The early computations were rather rough giving only a qualitative estimate to the solution. The main difficulty of the numerical simulation is due to the different scales of the flow domain and chemical reaction zone. Thus, the simulation for the real objects requires using more powerful computers or more sophisticated numerical algorithms. Developing the numerical algorithms is executed in several ways. In the first group the burning zone is not resolved by the grid points. Instead in [16] the chemical heat release is put into the Riemann problem. This idea is used in [28] as well. In [15], the chemical reaction term is present only to the energy equation, the kinetic equation is omitted and the Riemann problem is formulated for the nonreactive gas. Although the detonation wave speed is obtained rather inaccurately, the calculations of the real industrial objects with complex geometry are found satisfactory. In the second group of the algorithms, the burning zone is resolved by putting there several grid points in the normal direction. This requires to use very fine quasiuniform meshes. In the most of these algorithms one applies the fractional step approach (also referred to as the Strang splitting schemes). At each time step, first, the system of conservation laws is treated and then the ODE to the kinetic equation is solved, e.g. see [8,17,30,44,45,54]. Although the convergence of the fractional step method was justified theoretically for scalar conservation laws with source terms [19,53,52], the application for this approach for hyperbolic system with stiff source terms generally produces the nonphysical solution, e.g. see [17]. Another way is to treat the system of conservation laws coupled with the reactive equation as a whole, i.e. using the unsplit schemes. In this approach the heat release term in the right part of the system is treated as a source term. In [7], the generalized Riemann problem is introduced for the reactive equations to provide the second order approximation in time. In [20], the detonation process is simulated on the Lagrangian mesh. Space-time paths are introduced in [43] on which the equations are reduced to the canonical form about the ”new” Riemann invariants. All the above methods are of Godunov-type (except [16], where the random choice method is used), i.e. include solution of the Riemann problem that allows obtaining the narrow wave front rather precisely. In contrast to it, the random projection method is used in [6] where the Riemann problem is omitted from the consideration. However, justification of such a simplification is still under the question. Some other non-Godunovtype algorithms can be found in [42]. In this work, we present an unsplit scheme for calculating the reactive flow equations on the moving meshes. For this we utilize the idea of the Godunov’s scheme on the deforming meshes (see the monographs [1,32]), when the conservation laws are written in the integral form using the so-called generalized formulation in R3 space (x, y, t) (t is time). This allows updating the flow parameters directly on the moving curvilinear mesh without using interpolation. An implementation of the first-order Godunov’s method on 2 the moving mesh with front tracking was ...
