Supersonic flight and its effects on the pilot and residential areas

Abstract:   (12295 Views)
The first supersonic flight was performed in 1947, but flight with such speeds creates strong shock waves in the air surrounding the airplane that rises air resistance and temperature in the plane and can harm people and even constructions if the plane is close enough to the surface. The literature on the medical effects of supersonic flight can be classified in two domains: 1. medical effects on the pilot and possible crew 2. medical effects on people and their environment on the surface of the Earth. The major source of any medical harm to the pilot or the crew can be summarized in any kind of mechanical malfunction in the cockpit instruments and airtight seals. There are some minor affects due to high-altitude flight while flying supersonic speeds and in one case, the prevalence of hypercholesterolemia and hypertriglyceridemia were studied for supersonic pilots. The main concern on supersonic flight is the effects of its shockwaves on the people living on the surface of the Earth. One of the chief areas of study is the effect of the shockwaves on the sleep of residents, in some cases the studies have resulted in equations to predict the percent of people awakened by such noise. Sonic booms and aerial noise also have damaging effects on the potential of high school student’s learning.
