  1. Aerospace Medicine Objective Know the history of aerospace medicine and human engineering.

  2. Overview • Beginnings of Aerospace Medicine • Care of Flyers • Man and Machine • Research on the Fringe of Space

  3. Beginnings of Aerospace Medicine • Established in 1918 with the founding of the Army Aviation Medical Research Laboratory at Hazelhurst Field in New York. • Research was conducted to support flyers in WW I.

  4. Beginnings of Aerospace Medicine • The study of flight physiology started with the balloon ascension of Joseph and Etienne Montgolfier. • In 1783 they sent up a hot-air balloon in a demonstration for Louis XVI of France and his court at Versailles. This was an unmanned flight made with a sheep, a rooster, and a duck. • The balloon rose to an altitude of 1,500 feet and returned to the Earth with the animals unharmed.

  5. Beginnings of Aerospace Medicine • French physicist Jacques Charles made a flight in a hydrogen balloon that floated freely. • When he ascended to an altitude of 9,000 feet, he suffered a severe pain in his right ear. • He correctly attributed his pain to gas trapped in the middle ear. • In about 1787 he defined Charles’s Law: the volume of a gas is directly proportional to the temperature of that gas.

  6. Beginnings of Aerospace Medicine • In 1785 the American doctor John Jeffries and French balloonist Jean-Pierre Blanchard became the first to cross the English Channel in hydrogen balloon. • However, the journey….

  7. Beginnings of Aerospace Medicine • Coxwell and Glaisher made a flight of special scientific interest in 1862. • When they reached an altitude of 18,000 feet they became weak because of a lack of oxygen. • In total darkness at 29,000 feet they lapsed into unconsciousness. He later regained consciousness and continued to observe his symptoms. • Coxwell was finally able to grasp the balloon cord with his teeth and release enough gas to allow the balloon to descend.

  8. Beginnings of Aerospace Medicine • The Father of Aviation Medicine-Paul Bert • Conducted over 700 experiments with barometric pressure. • Proved the principle effects of altitude on the body. • Made the first low-pressure altitude chamber. • Schools of Aviation Medicine • The Signal Corp established an Aeronautical Division in 1907.

  9. Care of Flyers • The Armed Forces have doctors with special training in the care of flyers. • Flight surgeons perform periodic examinations on fliers to evaluate their physical and mental fitness. • The flight surgeon is not only concerned about the pilot but also the conditions the pilot finds in the cockpit.

  10. Man and Machine • The matching of man and machine is constantly under study by human engineering. • Every control and instrument in the aircraft must be developed with regard to the pilots needs. • Another area of importance in human engineering is in designing protective equipment for flight.

  11. Research on the Fringe of Space Balloons: • In 1931, Auguste Piccard perfected the oxygen-pressure gondola for balloons. • In 1935, Captains Anderson and Stevens ascended to 72,395 feet. • In 1957 Major Simons ascended to 102,000 feet. • In 1959, Captain Kittinger ascended to 102,000 feet and jumped safely to test high altitude parachute procedures • Then in 2012…..

  12. Research on the Fringe of Space • Research Aircraft: X-1 • The first U.S. rocket aircraft. • Chuck Yeager became the first man to fly faster the speed of sound in 1947

  13. Research on the Fringe of Space • Research Aircraft: X-15 • The X-15 reached a speed of 4,534 mph and an altitude of 354,200 feet. • Several pilots received astronaut ratings.

  14. Research on the Fringe of Space • Research Aircraft: X-24B • Wingless with a flat undersurface. • X-24B research program was conducted with NASA. • Altitudes: 70,000 ft at Mach 1.57

  15. Research in Space • Animal Astronauts • Mice and other small animals were used for the early experiments. • As rockets became more powerful, larger payloads could be sent into space. • Before American astronauts were rocketed into space, two chimpanzees (Ham and Enos) were used to test the mercury spacecraft and the flight plan.
