The Advanced Maneuverable Reentry Vehicle (AMaRV) was a prototype MARV built by McDonnell Douglas. Four AMaRVs were made and represented a significant leap in reentry vehicle sophistication. Three of the AMaRVs were launched by Minuteman-1 ICBMs on 20 December 1979, 8 October 1980 and 4 October 1981.
The concept has also been used to extend the reentry time for vehicles returning to Earth from the Moon, which would otherwise have to shed a large amount of velocity in a short time and thereby suffer very high heating rates. The Apollo Command Module also used what is essentially a skip re-entry, as did the Soviet Zond and Chinese Chang'e 5-T1.
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 ...
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.
In 2014, the U.S. Navy reported that images that have appeared on the internet showed similarities of a DF-21D re-entry vehicle to the American Pershing II missile's RV, which was withdrawn from service in 1988. The Pershing II's RV weighed 1,400 lb (640 kg) and was fitted with four control fins to perform a 25-G pull-up after reentering the ...
More specific statewide data from the California Highway Patrol says Honda Civics and Honda Accords made between 1992-2000 have the highest rates of theft in California in 2021.
China. Chinese DF-ZF hypersonic glide vehicle mounted on the DF-17 ballistic missile.. DF-ZF (developed and deployed) / Mach 5–10 [5]; GDF-600 (concept) In addition to a unified payload the Guangdong Aerodynamic Research Academy claims to be exploring fitting the conceptual weapon with various submunitions including what it calls a patrol projectile.
Its payload is believed to be 600 kg (1,300 lb) with a range of 900 km (560 mi) and improved accuracy of 30–45 m CEP. The DF-15B is a further upgraded variant with similar features, as well as an active radar seeker, laser rangefinder, and maneuverable reentry vehicle. It is capable of ranges between 50–800 km (31–497 mi) with greater ...
