Question

В каком положении тела космонавту легче перенести перегрузки при выходе корабля на орбиту??? Почему??

Answer 1

В лежачем. Потому что тогда вес тела более равномерно распределяется по большой площади опоры...

Answer 2

The Best Body Position for Astronauts to Withstand G-forces During Launch

When launching a spacecraft into orbit, astronauts experience intense acceleration forces, commonly referred to as G-forces. These forces can put a significant strain on the human body, potentially causing discomfort, disorientation, and even injury. To mitigate the effects of G-forces, astronauts are trained to assume specific body positions during launch.

The most common body position for astronauts during launch is the supine position, lying flat on their backs. This position allows the body to distribute the G-forces more evenly, reducing the strain on specific body parts and minimizing the risk of injury. By lying flat, the body's weight is distributed along the entire length of the body, from head to toe, rather than being concentrated in specific areas.

The supine position offers several advantages for astronauts during launch:

1. Spinal Alignment: Lying flat on their backs helps maintain proper spinal alignment, reducing the risk of spinal compression and injury during the high G-forces experienced during launch.

2. Even Distribution of G-forces: By distributing the G-forces along the entire length of the body, the supine position helps prevent excessive strain on specific body parts, such as the head, neck, and lower back.

3. Reduced Blood Flow Redistribution: During high G-forces, blood tends to pool in the lower parts of the body, potentially leading to a decrease in blood flow to the brain. The supine position helps counteract this effect by allowing blood to flow more evenly throughout the body, including the brain.

4. Improved Breathing: Lying flat on their backs allows astronauts to breathe more easily during launch. The supine position helps maintain proper lung expansion and prevents the diaphragm from being compressed, ensuring a steady supply of oxygen to the body.

It's important to note that the supine position is not the only body position used during launch. Depending on the specific spacecraft and mission requirements, astronauts may also assume other positions, such as a semi-reclined or seated position. These positions may offer additional benefits, such as better access to controls and instruments, or improved visibility during ascent.

In conclusion, the supine position, lying flat on their backs, is the most common body position for astronauts during launch. This position helps distribute G-forces more evenly throughout the body, reducing strain on specific body parts and minimizing the risk of injury. It also helps maintain proper spinal alignment, blood flow, and breathing, ensuring the well-being of astronauts during the intense acceleration of launch.
