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.
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 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.
The first known example was the Alpha Draco tests of 1959, followed by the Boost Glide Reentry Vehicle (BGRV) test series, ASSET [16] and PRIME. [17] This research was eventually put to use in the Pershing II's MARV reentry vehicle. In this case, there is no extended gliding phase; the warhead uses lift only for short periods to adjust its ...
The weapon, known as a Multiple Independently-targetable Reentry Vehicle (MIRV), carries a series of warheads that can each target a specific location, allowing one ballistic missile to launch a ...
Gemini Orbit Attitude and Maneuvering System, and Reentry (mislabeled "Reaction” [4]) Control System. The Mercury space capsule and Gemini reentry module both used groupings of nozzles to provide attitude control. The thrusters were located off their center of mass, thus providing a torque to rotate the capsule. The Gemini capsule was also ...
Failure to deactivate the engines would cause a catastrophic build up of heat in the vehicle as the atmosphere becomes denser during reentry, prematurely destroying the vehicle. Therefore, the terminal phase of an HGV's re-entry is similar to that of a multiple independently targetable reentry vehicle. For instance, the Avangard would not hit ...
By definition, hypersonic describes ... And, to be fair, the reentry vehicles of these two related weapons possess limited maneuverability that they can use to improve precision, and potentially ...
