Parachutes for NASAs Orion spacecraft passed key flight simulation test




Washington: NASA's next crewcraft parachutes, the Orion Capsule designed to carry people into space, have successfully passed a drop test, the US Space Agency said.

Orion's full parachute system consists of 11 parachutes – parachutes, two parachutes, three pilot parachutes and three main parachutes

These are designed to reduce the capsule's speed as it descends to the ground, thus enabling a safe landing in the ocean.

The Parachute System "On July 12, at the US Army's Yuma, Arizona proving ground, they were dropped off as planned from the area 1

0.6 kilometers away," NASA said.

Data from the seventh A total of eight tests "help NASA engineers certify Orion's parachutes for missions with astronauts" on Moon and Mars.

The test assessed parachute duty in conditions that exceeded the requirements for a crew-manned system.

Engineers dropped dropping the arrow-shaped test object from a height that allowed it to generate enough speed to simulate almost twice the force on the main chutes as would be expected under normal conditions.

Each of Orion's three main parachutes expands to one Diameter of 116 feet and contains enough fabric to cover 80 yards of a soccer field, but is in containers of the size of a large suitcase transported aboard the Orion.

For storage, the parachutes are compacted with hydraulic presses at forces of up to 80,000 pounds, baked for two days and vacuum-sealed.

After packaging, they have a density of about 40 pounds per cubic foot, which roughly corresponds to the wood of an oak.

The final test of the series, which is scheduled for September, will use a capsule form test article representative of the spacecraft NASA will use on Orion's upcoming missions.
