Crew Dragon Propulsion System Completes Development Testing

The propulsion system SpaceX would use to power its Crew Dragon out of danger has been test-fired 27 times as the company refines the design for the demands of operational missions carrying astronauts to the International Space Station for NASA’s Commercial Crew Program. SpaceX evaluated the system utilizing various thrust cycles on a test stand at its McGregor, Texas, rocket development facility.

Named SuperDracos, the engines are arranged in four pairs – SpaceX calls them ‘jetpacks’ – integrated around the outside of the Crew Dragon spacecraft. Firing all at once, the eight engines produce 120,000 pounds of thrust – enough power to accelerate a Crew Dragon from zero to 100 mph in 1.2 seconds. In the unlikely event of an emergency, that power means the ability to lift the crew a safe distance off the launch pad or far away from a booster failing on the way to orbit. That capability was demonstrated earlier this year in a pad abort test that confirmed the SuperDraco design in a flight-like condition.

A normal launch of the Crew Dragon atop a Falcon 9 rocket would not offer the SuperDracos anything to do during the mission since their only responsibility is to fire in an emergency to rescue the crew onboard. Eventually, SpaceX plans to use the SuperDracos in the place of a parachute during landing.

They use hypergolic propellants common in spacecraft thruster systems because the propellants ignite as soon as they contact each other. The engines are noteworthy for a number of reasons, including that they are built using 3-D printing methods instead of machining them from larger pieces.

After the development cycle, the propulsion system and SuperDracos will continue evaluations at the company’s test stand to qualify them for use on operational missions.

SpaceX and Boeing are developing a new generation of American-made, human-rated transportation systems capable of taking astronauts to the space station in partnership with NASA. The Crew Dragon and Boeing’s CST-100 Starliner will carry up to four NASA astronauts at a time, which ultimately adds another crew member to the space station and will allow twice as much time for astronauts to conduct research aboard the one-of-a-kind laboratory.

The magnet that moves only.

Download the experiment at the following link: http://www.mediafire.com/view/01ilu40sg0gfgm0/STEPS_TO_MAKE_THAT_THE_MAGNET_WILL_MOVE_ONLY.pdf

To build an electricity generator for cities and space travel in a perpetual manner.

To build a space engine that moves only. Not need electricity neither fuel.

It is a closed system.

CREATES MOVEMENT AND ELECTRICITY.
