ANALYSIS OF AERODYNAMIC CHARACTERISTIC ON GLIDE BULLET TO INCREASE RANGE

INTRODUCTIONIn order to increase bullet′s range,a greatdeal work has already been made.The generalmethod to increase range usually adopts drag re-ducing.For example,to add up base bleed orpertinently modify the shape of bullet and so on.Then the base- bleed bullet and base- concave- bul-let are got,which use the modified flow field toincrease range. Besides drag reducing techniqueto increase range,the method of increasing lift-force to increase range can also been adopted,which can make …     

NUMERICAL STUDY OF TWO INTERFACE METHODS FOR COMPRESSIBLE MULTI-FLUID FLOWS

INTRODUCTIONThe direct numerical simulation of com-pressible multi- fluid flows is an important re-search topic with various key applications.Therelatively dominant difficulty of simulation lies intreatment of the moving material interface. Ingeneral,there are two basic approaches to treatcontact discontinuities.The first,front trackingmethod[1,2 ] ,explicitly characterize the interfacemotion by the motion of individual points on theinterface. The other approach is front capturingmethod[3…     

Eye light flashes on the Mir space station

The phenomenon of light flashes (LF) in eyes for people in space has been investigated onboard Mir. Data on particles hitting the eye have been collected with the SilEye detectors, and correlated with human observations. It is found that a nucleus in the radiation environment of Mir has roughly a 1% probability to cause an LF, whereas the proton probability is almost three orders of magnitude less. As a function of LET, the LF probability increases above 10 keV/micrometer, reaching about 5% at around 50 keV/micrometer.
