…to make the descent trajectory less steep, thus increasing the distance of the atmosphere flight and reducing acceleration stresses (or loads).Reentry was noticeable by the gradual increase in deceleration stresses (or loads) and flames in the windows.The controlled reentry glide-path makes it possible to reduce the stress-loads in the course of reentry down to 3-4 units.Such space-flight factors, as ionizing radiation, long-time absence of normal hygienic conditions, increased g-forces… -
