a Raytheon engineer who has printed working rocket motors. achines making machines. The user could print on demand.
And we demonstrated a printed rocket motor. Wee already printed 80 percent of what would go into a missilesaid Danforth. 3d printing of missiles
Now NASA has proved that even rocket motors can be made this way. Engineers led by Tyler Hickman in the Game Changing Technology Program at NASA's Glenn Research center in Cleveland Ohio worked together with rocket motor maker Aerojet Rocketdyne of Sacramento California.
They wondered if additive layer manufacturing the engineer's name for 3d printing could make a precision part called a rocket injector in less time than the year it takes using conventional methods.
because rocket motor designs are covered by US laws that prevent them from being exported revealed to non-Americans.
a rocket motor for rapid acceleration; and ramjets for high-altitude cruising. The turbojets and rocket motor fold into the body of plane
when not in use and the plane also has adjustable fins to make it more aerodynamic. It would be fuelled by hydrogen and liquid oxygen.
A rocket motor would take it to an altitude of 100, 000ft (30,000 metres. The wing-mounted ramjets would then take control to push the jet to its final speed.

which is currently studying the dwarf planet Ceres. Ion thrusters are considerably more efficient than conventional rocket motors.
but once in the air, an open door in the stern of the plane reveals a rocket motor. When this fires, it sends the aircraft into a near vertical trajectory,
000 ft). The rocket motor shuts down and is concealed again as the aft door slides shut to reduce drag.
and only the rocket motor requires special maintenance. According to its specifications, it could carry two or three tons of cargo,
