| Popis: | As the Reusable Launch Vehicle can reduce the launching cost, and improve the ability of Operationally Responsive Space (ORS), many aerospace powers in the world consider the Reusable Launch Vehicle as a main development tendency of space transportation system. Recently, Space Exploration Technologies Corporation (SpaceX), as the spokesman of private aerospace corporations, has attracted all the world’s attention to the Reusable Launch Vehicle. SpaceX has been developing technologies for rockets’ fully and rapid reusability, and several recovery tests have been conducted on technology-demonstrators and post-mission controlled-descent tests on Falcon 9 rockets’ first stages, both touchdown on the ocean platform and the land. On 22 December 2015, a Falcon 9 FT rocket of SpaceX, carrying 11 Orbcomm communications satellites, lifted off from Cape Canaveral. After cutoff and stage-separation, the Falcon 9s first stage flight back into the atmosphere and pulled off a powered landing on on Landing Zone 1, which is about 10 km far away from the Launch Site of SLC-40, settling to a smooth tail-first touchdown, making it a significant space “first”. After already celebrated a successful booster landing, SpaceX had decided to attempt a landing at sea on this flight despite available margins for a return to land. This decision was prompted by the need to master the landing sequence for sea-based recoveries which will be needed for about half of Falcon 9’s flights when lifting heavy satellites to high-energy orbits. On 8 April 2016, SpaceX’s Falcon 9 FT rocket, carrying CRS-8 Dragon cargo, lifted off from Cape Canaveral. The Falcon 9’s first stage has accomplished the first ever successful returning rocket on the Autonomous Spaceport Drone Ship (ASDS). This is considered a landmark accomplishment on the road to economical interplanetary and asteroid-to- planet space travel because it enables expensive launch vehicles to be reused. In this paper, based on the experiments of Falcon 9, and analyzing the main projects of the Reusable Launch Vehicle abroad in the past 60 years, the critical technologies will be researched and the results will provide references for the research of new type of space transportation systems. |
