In this book, Dr. Andras Sobester reviews the science behind high
altitude flight. He takes the reader on a journey that begins with
the complex physiological questions involved in taking humans into
the "death zone." How does the body react to falling ambient
pressure? Why is hypoxia (oxygen deficiency associated with low air
pressure) so dangerous and why is it so difficult to 'design out'
of aircraft, why does it still cause fatalities in the 21st
century? What cabin pressures are air passengers and military
pilots exposed to and why is the choice of an appropriate range of
values such a difficult problem? How do high altitude life support
systems work and what happens if they fail? What happens if cabin
pressure is lost suddenly or, even worse, slowly and unnoticed? The
second part of the book tackles the aeronautical problems of flying
in the upper atmosphere. What loads does stratospheric flight place
on pressurized cabins at high altitude and why are these difficult
to predict? What determines the maximum altitude an aircraft can
climb to? What is the 'coffin corner' and how can it be avoided?
The history of aviation has seen a handful of airplanes reach
altitudes in excess of 70,000 feet - what are the extreme
engineering challenges of climbing into the upper stratosphere?
Flying high makes very high speeds possible -- what are the
practical limits? The key advantage of stratospheric flight is that
the aircraft will be 'above the weather' - but is this always the
case? Part three of the book investigates the extreme atmospheric
conditions that may be encountered in the upper atmosphere. How
high can a storm cell reach and what is it like to fly into one?
How frequent is high altitude 'clear air' turbulence, what causes
it and what are its effects on aircraft? The stratosphere can be
extremely cold - how cold does it have to be before flight becomes
unsafe? What happens when an aircraft encounters volcanic ash at
high altitude? Very high winds can be encountered at the lower
boundary of the stratosphere - what effect do they have on
aviation? Finally, part four looks at the extreme limits of
stratospheric flight. How high will a winged aircraft will ever be
able to fly? What are the ultimate altitude limits of ballooning?
What is the greatest altitude that you could still bail out from?
And finally, what are the challenges of exploring the stratospheres
of other planets and moons? The author discusses these and many
other questions, the known knowns, the known unkonwns and the
potential unknown unknowns of stratospheric flight through a series
of notable moments of the recent history of mankind's forays into
the upper atmospheres, each of these incidents, accidents or great
triumphs illustrating a key aspect of what makes stratospheric
flight aviation at the limit.
