Rocket Interceptor Solutions

ការប្រើកាំភ្លើង ២០មម បាញ់ការពារអាកាស (ប្រឆាំងកាំភ្លើងធំ ៧០មម)

Baumann compares the use of both gun and rocket interceptor solutions against a notional RAM type target in Figure 7. The red curve shows the intercept velocity versus intercept range for a notional gun firing a 20 mm projectile with a muzzle exit velocity of about 1100 m/s. The black curve shows the same profile for a notional 70 mm bore, 11 kg hypervelocity rocket (HVR). The straight blue curve gives a postulated lethality requirement achieved with a kinetic energy delivered at 800 m/s.

Baumann concludes that a gun or rocket system would provide the necessary kinetic energy to destroy this notional target at the shorter range SRIT requirements (0-2 km). From the notional velocity profiles, note that a gun solution is especially better than a rocket at delivering kinetic energy at very short range, since the rocket requires a certain distance after launch to achieve maximum velocity, where as a gun fires its projectiles at maximum velocity. However, the rapid velocity decay of a bullet as soon as it leaves the gun muzzle severely limits the amount of kinetic energy it can deliver at longer ranges such as those dictated by the LRIT requirement (2-10 km). In fact, the 20 mm gun solution appears to be able to deliver that required kinetic energy up until about 2 km (the boundary of the SRIT/LRIT requirements), and the rocket delivers the required kinetic energy up until about 3.5 km. A self propelled solution such as a rocket may be required to maintain a certain velocity profile at a ceratin range, depending on the amount of kinetic energy required at an intercept​range. This clearly shows how the required defendable radius for a single solution drives the weapon design requirements.
