Two successful NASA Langley Research Center led sub-orbital flight demonstrations of HIAD technology have occurred; Inflatable Reentry Vehicle Experiment 2 (IRVE-2) [7] and IRVE-3 [8] were flown in 2009 and 2012 respectively. LOFTID is the first orbital flight of a HIAD and the largest blunt bunt aeroshell entry to date.
Early reentry-vehicle concepts visualized in shadowgraphs of high speed wind tunnel tests. 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, to a large extent, to chipping or cracking of ...
The X-38 is an experimental re-entry vehicle designed by NASA to research a possible emergency crew return vehicle (CRV) for the International Space Station (ISS). The 1995–2002 program also developed concepts for a crew return vehicle design that could be modified for other uses, such as a possible joint U.S. and international human spacecraft that could be launched on the French Ariane 5 ...
4. About 180 seconds after launch, the third-stage thrust terminates and the post-boost vehicle (D) separates from the rocket. 5. The post-boost vehicle maneuvers itself and prepares for re-entry vehicle (RV) deployment. 6. While the post-boost vehicle backs away, the RVs, decoys, and chaff are deployed (this may occur during ascent). 7.
The path of the reentry vehicle is the upper streak of light, with the booster tanks immediately below. Lights from the Kwajalein Atoll in the Pacific can be seen in the lower right corner. The Advanced Maneuverable Reentry Vehicle (AMaRV) was a prototype MARV built by McDonnell Douglas.
Instead, the vehicle would be heavily modified externally into an ASSET-like lifting-reentry configuration. Post-reentry, a pair of stowed swing-wings would be deployed, giving the spacecraft sufficient lift-to-drag ratio to make a piloted glide landing on a concrete runway using a skid-type landing gear (reinstated from the planned, but ...
A reentry capsule is the portion of a space capsule which returns to Earth following a spaceflight. The shape is determined partly by aerodynamics ; a capsule is aerodynamically stable falling blunt end first, which allows only the blunt end to require a heat shield for atmospheric entry .
Such objects are often completely destroyed by reentry heating, but large enough objects or components can survive. Most of the objects which reenter are relatively small; larger objects have survived but usually break up into smaller pieces during reentry. [1] [2] [3]
