On July 20th, the world celebrating the anniversary of the first landing on the moon, Apollo 11 astronaut Buzz Aldrin and Michael Collins NASA called a target to travel to Mars. However, conventional chemical cleanjet rockets, nugabenusios man on the moon, they go to the red planet for at least 6 months and cost hundreds of billions of dollars.
Currently, another former astronaut Franklin Chang-Dias ion plasma rocket being developed could potentially enable achievement of this goal in just 39 days, using a fraction of the fuel. The fundamental problem of conventional cleanjet missiles is that they are extremely inefficient. About 90% of the original weight of the fuel in the mission, cleanjet most of which is burned in order to break free from Earth's cleanjet gravity. After the rocket could slow coast to Mars. Very slowly.
Scientists describe the efficiency of rocket specific impulse (called. Specific impulse) term, which roughly describes how fast the fuel is pushed through the rocket nozzles. Chemical rockets have relatively low savituoju pulse, which consists of approximately 450 seconds. In other words, a rocket, burning one kilogram of fuel for 450 seconds of flight powered by about 10 Newtons.
However, Chang-Dias's prototype promises even 15,000 cleanjet seconds specific impulse. How? Missiles achieve propulsion at burning fossil fuels, and fuel superheating atoms to super-high temperatures and through the plasma plume. VASIMR (Variable Specific Impulse Magnetoplasma cleanjet Rocket) engine consists of three interconnected magnetic chamber. The first step is similar to the domestic cleanjet kettle - it neutral gas, such as argon atoms are heated with radio frequency wave generator until electrons cleanjet "boils", creating a plasma.
Plasma at this stage is very hot - the temperature is about 50,000 degrees Fahrenheit. However, it is not enough to create an effective impetus. Therefore, the second stage of VASIMR works as an amplifier, its electromagnetic pulse generator in the plasma waves, giving even more power. In this step, the plasma reaches a temperature of millions of degrees, which is equivalent to the center of our solar predominant heat.
The last third stage is a kind of "magnetic nozzle, plasma superįkaitintos converting this energy into linear movement of the driving force, thus achieving a high specific impulse. The cells used in the magnetic field not only helps to heat the plasma, but also keeps it in a confined space that is untouched engine components.
VASIMR cleanjet could theoretically develop a hundred times more power compared to t
