WebBlunt Body Entry Vehicles. These four shadowgraph images represent early reentry-vehicle concepts. A shadowgraph is a process that makes visible the disturbances that occur in … Practical development of reentry systems began as the range, and reentry velocity of ballistic missiles increased. For early short-range missiles, like the V-2 , stabilization and aerodynamic stress were important issues (many V-2s broke apart during reentry), but heating was not a serious problem. See more Atmospheric 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. There are two main types of atmospheric entry: uncontrolled entry, … See more When atmospheric entry is part of a spacecraft landing or recovery, particularly on a planetary body other than Earth, entry is part of a phase referred to as entry, descent, and landing, or EDL. When the atmospheric entry returns to the same body that the … See more There are several basic shapes used in designing entry vehicles: Sphere or spherical section The simplest axisymmetric shape is the sphere or spherical section. This can either be a complete sphere or a spherical section forebody … See more In 2004, aircraft designer Burt Rutan demonstrated the feasibility of a shape-changing airfoil for reentry with the sub-orbital See more The concept of the ablative heat shield was described as early as 1920 by Robert Goddard: "In the case of meteors, which enter the atmosphere with speeds as high as 30 miles (48 km) per second, the interior of the meteors remains cold, and the erosion is due, … See more Objects entering an atmosphere from space at high velocities relative to the atmosphere will cause very high levels of heating. … See more A thermal protection system, or TPS, is the barrier that protects a spacecraft during the searing heat of atmospheric reentry. A secondary goal may be to protect the spacecraft from the heat and cold of space while in orbit. Multiple approaches for the thermal protection … See more butane wall heaters

WebMar 2, 2024 · blunt body. b. slender body. Image source Ref [1]. Moving on, many other studies on the subject have shown that the wake characteristics scale with diameter. Behind slender bodies, the wakes close earlier and are much thinner. As a consequence, the dynamic pressure recovery is much faster compared to that for a blunt body.
