Earth’s gravity is essentially the reason why airplanes cannot fly in
space. Moreover, NASA, despite new technology, sometimes encounters different
problems in being able to operate its shuttle in space.
The first attempt to put a human in space was not made using an airplane, but
with a rocket. According to NASA, any object designed to escape gravity must have the
ability to exceed a speed of 7 miles per second (11 kilometers per second). The disadvantage
of subsonic commercial airplanes is that they cannot fly nearly as fast and their engines
cannot produce the thrust necessary to propel them at these speeds.
Also, there is a fuel problem. The shortest distance between Earth and space is
about 62 miles (100 kilometers) up, which by general agreement is where the planet’s
boundary ends and suborbital space begins.
To get shuttles into space, NASA uses a combination of two solid
fuel boosters with approximately 140,500 liters of fuel, along with an external
liquid fuel tank, to launch a space shuttle that can exceed a weight of 100 tons and
propel it into space in less than 9 minutes.
Flying horizontally, it would require a volume of fuel so large that the probe would not even be
capable of carrying it.
Airplanes could theoretically be capable of flying into orbit, if they were specially
designed to do so. All conventional airplanes produced today that are used for commercial
flight use the airfoil effect to stay in the air, which requires relatively
low speeds. However, the airfoil effect has no use in space.
The fact that the space shuttle has wings has nothing to do with flight in space, but rather that they
are used upon re-entry into Earth’s atmosphere to fly in the same way as airplanes,
so that the space shuttles would be reusable.
To this end, I strongly invite you to follow me. I will be very delighted to meet you there and
to share with you new articles in the form of videos addressing the subject of aeronautical
science and aerospace.
