The Flometrics Pistonless rocket fuel pump is a highly reliable pump that uses two pumping chambers alternatively filled with fluid and pressurized in sequence to maintain a steady flow of pressurized propellant to a rocket engine. Because of its reliable and innovative technology, it is both cost...
A new system is proposed for the low-cost launching of large quantities of rocket fuel into Earth orbit and the storage and transfer of the fuel to the NASA Space Station. The system consists of an electromagnetic launcher that fires heat-shielded fuel tanks into high Earth orbit, where they...
The cost of a shopping basket of food has rocketed by 12.6 percent during the past year,according to researchers.It is further bad news for the nation, which has recently suffered the fastest increase in the cost of food and fuel (燃料) since the 1970s,the Daily Mail revealed last week...
Hybrid rocket propulsion has been incorporated in the development of a micro launch vehicle for space launch and flight experiment applications of Taiwan. With the proposed hybrid rocket launch vehicle design in this research using an enhanced-mixing combustion method, hybrid rocket engines can also de...

Since then, Palestinian militants have launched “tens of thousands” of rocket and mortar attacks into Israel. On October 7, Hamas fired between 2,200 and 3,000 rockets into Israel in 20 minutes, overwhelming the Iron Dome defense system. ...
Work so far has been done with Prometheus mounted in an early prototype of a reusable rocket stage, called Themis, which is being developed in parallel with the engine under contract from ESA. While engine testing continues, work is also underway to prepare a more advanced Themis prototype for...
But RDX has accomplished the difficult task of developing a hybrid rocket engine that solves the issue with the oxidizer-to-fuel ratio to keep the combustion efficiency high enough to get into orbit. Crucially, as the propulsion system is much simpler than traditional rocket engines, manufacturing...
