The design method presented in this paper is for utilizing, fast and easy system designing of orbital transfer block for transferring satellite from park orbit to destination orbit. The main purpose of this paper is system designing liquid propellant orbital transfer block with a new approach for ideal orbital transfer and presenting a simple interfered systematic method for designing aerospace products. Designing orbital transfer block consists of designing all subsystems and integrating all parts of design. Designing all subsystems can be achieved with a meaningful connection between all system and subsystem constraints. In addition to systematic design approach to each of the design sub algorithms, creating subsystem optimization environment according to physical performance of subsystem and also general integration of orbital transfer block system design in an optimized environment have been carried out. Final result of orbital transfer block design for a specific mission is through mass-dimension convergence of equations in integrated design. Design integration according to design matrix and optimizations and convergences of the design is discussed in the paper. According to presented method, which is scientific, functional and extensible to final design of the product, parametric process of results is briefly validated. So in this paper new method is provided for integrating the design in an optimized and collaborative convergence environment maintaining all systemic constraints and limitations to specify specifications of orbital transfer block systems and subsystems.

In this article the simulation of explosion and diffusion of debris consequent on explosion, in the space are studied. This method is simulated by the introduced code and the results are closely checked in accordance with different operational situations for the huge amounts of particles in different kinds of strategic orbits. Finally, the density distribution of debris that located in the same orbit is studied. The simulation examines the status of diffusion, trace settlement and also their location in orbits around the earth, during times that is wanted by user. Whatever satellite designing is immaculate, the satellite subsystems (such as batteries, propeller parts and etc) explosion and failing is possible, also smashing with the space masses is foreseeable. Regarding to the space orbits high expense and dedicating these orbits to each country; it is important to clean them from debris and necessary to understand this problem.
