Question

find out what happens to the respiratory system of pilot who is in the supersonic plane

Answer 1

Normally when we breathe in, air passes through our nostrils into the nasal cavity. Air then reaches the lungs, which are located in the chest cavity. The actual mechanism of breathing involves the movement of the rib cage  and the diaphragm, Which are located around and at the base of the chest cavity respectively. But jet fighter pilots were supplied a mixture of oxygen and air depending on the altitude the pilot is flying at. When flying at a higher altitudes more oxygen is added to the air so to compensate for lower air pressure whereas, a 100 percent mixture of oxygen is supplied if flying at high enough altitudes that to delivered at a high pressure. Here in such situation, the pilot breathes in by relaxing hisdiaphragm, and must forcibly expel air to breathe out this would unable the pilot to talk while breathing out, only while breathing in.
