The components of a satellite falling to the ground is a crucial problem, since titanium tanks are one of the component causing most damage to the ground in satellites. To replace titanium tanks, JAXA has researched a Melting Promotion Type Tank whic

The compositions with tie-lines between the », ·, £, i, and Nb(Cr,Re)2 phases in a ternary ReCrNb system were investigated at 1500°C by heat-treating various ternary ReCrNb alloys in vacuum for either 2 or 220h. The microstructures of the

Most mono-propellant thruster technologies were developed in the 1960s and the basic principles and fundamental structures, such as the catalyst and propellant, have remained in use without major technical innovation. Conversely, much remains to be i

Because the titanium tank is one of the greatest ground-damaging component when a low-Earth orbit satellite falls to ground, we plan to replace the general titanium propellant tank with a reentry melting promotion-type tank to reduce the ground hazar

Monopropellant Hydrazine Thrusters are widely used in many satellites and explorers propulsion systems and launch vehicle RCSs due to their simple and low cost features. The first generation Japanese 1N thruster design is based on the US TRW 1970s de
