Abstract With regard to the space field, number of sensors has grown for a middle-sized spacecraft from more than 500 at beginning twenty-first century [1] several thousands nowadays applications. Meanwhile, Reusable Launch Vehicles (RLVs) moved their steps demonstrators commercial working systems. As result, Health Monitoring (HM) is conquered its own in field and are primary elements required...
The resource levels required for operation and support of reusable launch vehicles are typically defined through discrete event simulation modeling. Minimizing these resources constitutes an optimization problem involving discrete variables and simulation. Conventional approaches to solve such optimization problems involving integer valued decision variables are the pattern search and statistic...
One of NASA’s goals is to enable commercial access to space at a cost of $1000/lb (an order of magnitude less than today’s cost) by approximately 2010. Based on results from the 1994 Congressionally mandated, NASA led, Access-to-Space Study, an all rocket-powered single-stage-to-orbit reusable launch vehicle was selected as the best option for meeting the goal. To address the technology develop...
Polymer Matrix Composite (PMC) hydrogen tanks have been proposed as an enabling technology for reducing the weight of Single-Stage-to-Orbit reusable launch vehicles where structural mass has a large impact on vehicle performance. A key development issue of these lightweight structures is the leakage of hydrogen through the composite material. The rate of hydrogen leakage can be a function of th...
SpaceX's successful development of reusable rockets and the realization low-cost operations have significantly impacted space industry, institutions, companies. Price competitiveness has become a hot topic for launch vehicle development. A hydrogen-fueled rocket engine can be its solution. The developed countries are attempting to improve performance reliability engines using hydrogen-fuel. Thi...
JAXA, CNES and DLR have decided to join their force develop fly a scaled reusable VTVL rocket stage called CALLISTO (Cooperative Action Leading Launcher Innovation in Stage Toss - back Operations). This vehicle will pave the way for future launch vehicles. One of its main goals is demonstrate mastering key techniques technologies that be needed later by operational Indeed frame numerous challen...
