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 ...
The ADS (Active Defence System), formerly known as AMAP-ADS, is a hard-kill active protection system (APS), developed by the German company ADS Gesellschaft für aktive Schutzsysteme, a subsidiary of Rheinmetall and IBD Deisenroth Engineering, [1] as part of their Advanced Modular Armor Protection concept.
The random nature of fragmentation required the military vest specification to trade off mass vs. ballistic-benefit. Hard vehicle armor is capable of stopping all fragments, but military personnel can only carry a limited amount of gear and equipment, so the weight of the vest is a limiting factor in vest fragment protection.
Atmospheric entry (sometimes listed as V impact or V entry) is the movement of an object from outer space into and through the gases of an atmosphere of a planet, dwarf planet, or natural satellite. Atmospheric entry may be uncontrolled entry, as in the entry of astronomical objects, space debris, or bolides.
