Non-ballistic atmospheric entry is a class of atmospheric entry trajectories that follow a non-ballistic trajectory by employing aerodynamic lift in the high upper atmosphere. It includes trajectories such as skip and glide. [1] [2] Skip is a flight trajectory where the spacecraft goes in and out the atmosphere.
Ablative armor is armor which prevents damage through the process of ablation, the removal of material from the surface of an object by vaporization, chipping, or other erosive processes. In contemporary spacecraft, ablative plating is most frequently seen as an ablative heat shield for a vehicle that must enter atmosphere from orbit, such as ...
Prior to this, the FSBE series replaced the older Close Quarters Battle Equipment Assault Vest (CQBE AV) that had been used by Force Recon since 1996. This kit is available to civilians, with prices for the FSBE vest body starting at US$500. This price does not include any ancillary pouches or soft armor or hard ballistic armor inserts.
The company began as a regular clothing line, and later changed its focus to ballistic clothing, an idea that Haider and Davis developed for a 2011 university class at the University of Mary Washington. The two met with a ballistics producer and built a prototype suit, and began fielding queries from government agencies within a few months.
Intercept: Most systems can be used in different phases of ballistic missile flight, i.e., boost [72] (where surface or air-launched anti-aircraft missiles might also be effective because the ballistic missile is moving relatively slowly at low altitude), requiring proximity to the launch site and immediate response, mid-course/exo-atmospheric ...

Iron armor could be carburized or case hardened to give a surface of harder steel. [9] Plate armor became cheaper than mail by the 15th century as it required much less labor and labor had become much more expensive after the Black Death, though it did require larger furnaces to produce larger blooms. Mail continued to be used to protect those ...
