The relatively small and – compared to NASA’s shuttle system – cheap craft was tested in the Mojave desert. It reached an altitude of 360,000 feet. Using a hybrid rocket engine, SpaceShipOne used both liquid and solid propellant to propel it into space. However, after making two groundbre...
ReFEx uses an “inverse” 2 + 2 hybrid protoflight model philosophy on system level to cover the boundary conditions implied by the sounding rocket launch vehicle, combining 2 stripped-down qualification models, one protoflight- and one ground reference model. Final launcher integration will take ...
temperatures. This process is surprisingly easy, due to the rocket’s tanks storing propellant at relatively high pressure, usually three-to-six bars. Because of this, some valves can just be opened, and the pressure from the tanks will ensure propellant flows from the tanks through the engine...

The cathode uses a tungsten filament for electron emission and can be seen mounted in Fig. 4 and Fig. 9 on the bottom side of the image, it can be seen more clearly in the neon discharge. This is not a space grade cathode and requires non-negligible mass flow rate of propellant to ...
During the initial stage of firing (T=7 ms), after the initial ignition of the propellant generates extremely high chamber pressure, the projectile bottom experiences propulsion, and the mass block recoil initiates bottle breaking. For rifled guns, the projectile undergoes both forward and rotational...
