In terms of velocity range of the impacts, structural hazard at very large velocity of over a few km/s is much investigated. However, lower velocity impacts can also be encountered, with similar fatal effects to spacecraft. Examples are debris impacts in geostationary altitude and those onto ...
1. A projectile (10) comprising: a fuselage (12) having an outer surface; fins (14) hingedly coupled to the outer surface of the fuselage (12); and fillers (18) in spaces (16) between the fins (14) and the outer surface when the fins (14) are in a compact configuration, close ...
The determination of the active projectile velocity required for the correction computation and the correction of the disaggregation time (Tz(v) are performed in a projectile after it has been fired. The velocity measurement takes place in the form of a measurement of a first time (t) which is...
azimuthal symmetry, with the highest vulnerability on both sides, and the lowest vulnerability in the front and rear. The most vulnerable orientations of the satellite are(elevation angle) and∘(azimuth angle), with vulnerable areas for A-level and B-level damage measuring 5.731 m2and 6.466 m2...
a batting cage of this type of construction. In actual use this type of construction imposes several disadvantages. Balls may strike the rigid material resulting in damage over the long term. The rigid materials can also cause high energy rebounding of the ball resulting in a safety hazard or ...
shell falling back to the ground also cause a safety hazard to people on the ground who could be hit and injured by the fallout. Moreover, after detonation, portions of the shell can and often do fall back to the ground as burning debris. This causes a severe fire hazard in many areas...
to induce the break-up of the frangible projectile body which is already in a prestressed condition due to the spinning motion of the projectile. Subsequent to break-up, the resultant fragments are dispersed and are decelerated by aerodynamic drag to a degree where they cease to be a hazard...
