To reveal the effects of hypersonic flow field on the scattering characteristics of a reentry vehicle
in wide wave bands, backward RCSs of a reentry vehicle
enveloped by a hypersonic flow field are analyzed using a high-order auxiliary differential equation finite-difference time-domain (ADE-FDTD) method in this paper, where the hypersonic flow field is established by solving the NS equations numerically under different flight conditions.
[[??].sub.s] indicates the heating rate at a specified point on the surface of the reentry vehicle
, which normally chooses the stagnation point on the nose.
(2.) Since the entire V-2 impacted the target, there was no true separable reentry vehicle
. (3) The original design called for the use of a lightweight alloy of magnesium and aluminum but wind tunnel tests indicated that from an altitude of 43 nautical miles, the operational maximum altitude, reentry into the lower atmosphere at 3,345 miles per hour would result in a warhead compartment skin temperature of 1,250 degrees Fahrenheit.
many tests to develop reliable solid-fueled ICBMs and their requisite warhead reentry vehicle
As the reentry vehicle
is at low altitude, where the air density is larger, increasing the lift-drag ratio can slow down the speed of the vehicle descent rate.
During the hypersonic reentry stage of a space mission, the shock in front of the reentry vehicle
leads to aerothermal heating on the gas around the vehicle.
The Zolfaqar also claims advanced guidance technology as well MIRV (a multiple independently targetable reentry vehicle
) capabilities, allowing for multiple warheads to strike different targets.
Along with other contributors, he describes the use of reconnaissance cameras in space, the Hexagon camera system, the Perkin-Elmer organization, the early days of Hexagon, production and design aspects, reliability aspects, manufacturing and testing, field operations, the characteristics of the film used, the electronics, the sunken reentry vehicle
, and the explosion that caused its end in 1986.
"We are working on increasing our missiles' precision and want to make them impenetrable to electronic warfare and interception, " adding that long-range ballistic missiles with multiple reentry vehicle
payloads have been domestically produced, saying, "we are after turning our ground-based missiles into air-launched missiles."
explosion, the reentry vehicle
from a ballistic missile would have to be
Generally, the hypersonic reentry vehicle
enters the atmosphere of the Earth at an altitude of about 100~120 km.
Pyongyang has yet to develop a nuclear warhead small enough to fit atop its missile, experts say, and it has not tested a reentry vehicle
that can withstand the heat of the atmosphere.
