NewRocket: Developing advanced, environmentally friendly ("Green Propulsion"), rocket engines based on innovative gel-propellant technology.
Since the energetic materials used in high-performance propellants are often explosives, manufacturing the propellant is a complex technology involving special facilities and strict safety guidelines.
The analysis shows that, with current understanding of the available technology for propellant production, transportation systems, and the market for launch of vehicles between LEO-GEO, it is difficult to demonstrate that a viable commercial opportunity exists to serve that market with lunar propellant.
An in-space propellant depot not only requires technology development in key areas such as zero boil-off storage and fluid transfer, but in other areas such as lightweight structures, highly reliable connectors, and autonomous operations.
The objective of this study is to investigate the drag reduction effect of a new launch technology by utilizing propellant gases to drain off water in the front of the projectile inside the gunbarrel for submerged launch process of underwater gun.
Between them, the three companies are spending an initial $12 billion or so to create their platforms.All three services will exploit recent advances in satellite technology, such as lighter propellant systems and batteries with longer-lives, which cut both manufacturing and launch costs.
Long thought to be nothing more than a space dream, the EmDrive, a rocket propulsion technology that requires no propellant, has cleared peer review, the International Business Times reports.
These areas include air-compatible cathode technology, techniques to improve propellant utilization on atmospheric species, in-space compressor and liquefaction technology, improved hypersonic and hyperthermal free molecular flow inlet designs, and improved understanding of how design parameters affect system performance.
By the end of the 19th century, when black powder was supplanted by nitrocellulose-based propellants, steam power had become a mature technology, the scientific revolution was in full swing, and the age of electronics and the internal combustion engine was at hand.
