Do you know what happens when a spacecraft returns to the earth from space? There is a speed of 28000 km per hour. The spacecraft becomes a fireball. He has to face temperatures up to 7,000 degrees farehite. The astronauts sitting inside have four times more force than the gravitational force of the earth. All this needs to successfully need the world’s most advanced technology. A single lapse can be overshadowed here. You will ask why we are telling you this. In fact, Indian -origin astronaut Sunita Williams has left the International Space Station for the earth.
Let us tell you what is made of a dragon spacecraft that keeps the astronauts sitting inside completely safe despite turning into a fireball while coming into the atmosphere or atmosphere of the earth.
In the first pointors, you tell you the specialty of the dragon spacecraft-
- According to Spacex, the Dragon Spacecraft has completed 49 missions so far. It has gone to the International Space Station 44 times. After returning to Earth 29 times, he has traveled to space again.
- The Dragon Spacecraft is capable of taking 7 passengers from the orbit of the earth, ie orbit and beyond.
- It not only goes into space but it also comes back and can also be used again.
- The dragon has Drako thrusters who allow the dragon to change the direction while living in an orbit. It has 8 superdrecoses tomorrow which strengthens the launch of spacecraft.
What is the dragon made of?
Dragon capsules are made of many different materials. Each of them has been selected for its special qualities and benefits from it:
Carbon Fiber Reinforced Polymer (CFRP): The primary structure of the dragon capsules is made of CFRP, it has extraordinary strength in the ratio of weight, it has the power to prevent iris, corrosion and it provides durability to the capsule.
Aluminum alloy (alloy): Some of its parts, such as capsules frames and some structural elements, are made up of high -power aluminum alloys (eg, 2219 and 6061).
titanium alloy: Titanium alloys (for example, TI-6AL-4V) are used to create parts that require high strength, low density and corrosion resistance, such as fasteners and fittings.
Thermal Protection System (TPS): Dragon capsule’s heat shield is made up of a material called PICA-X, which is a type of phenolic impregnated carbon ablator (PICA) material. The thermal provides the thermal protection despite the pica-x dharki changes into a fire shell during re-entry.
Multilayer Insulation (MLI): The outer part of the capsule is wrapped with a MLI blanket, which includes several layers of reflective materials (eg, aluminalized milers) separated by low-conductity spacer. MLI helps reduce heat transfer and maintain stable internal temperature.
