From the manned space engineering ,safety difinition,safety model,and relationship betwinn reliability and safety of the manned space flyer have deeply been discussed in this paper.
With the aid of event tree analysis of all states,this paper has advanced a safety analysis modol of the manned space flyer ,and devived from this model a formula for probabilistic approach to safety of the manned space flyer.
Reliability quote of total and subsystem of X- space station is designed based on reliability index and statistical data of manned space flyer fault in a literature from Russia.
Objective The analytic solution of the overall pressure and o xy gen partial pressure in the sealed module of manned space vehicle was deduced,it can be used by ECLSS overall engineering designer to predict the pressure contr ol parameters when space flight or ground test is operating.
To precisely determine the integrated orbit of the Chinese manned spacecraft mission, a smoother and Bayesian filter based technique for optimum semi-codeless tracking of the P(Y) code on dual-frequency GPS signals has been advanced.
Among the hazards that accompany the penetration of a pressurized manned spacecraft are critical crack propagation in the module wall, crew hypoxia, and uncontrolled thrust due to air rushing out of the module wall hole.
By a combination of multi-spectral, remotely sensed data, visual observations from manned spacecraft, and ocean data gathered by ship and aircraft, the oceanography off southwest Spain has been determined as never before (Fig.
