Before the first H-bomb was exploded, there were only a few pounds of tritium-a triple-weight, radioactive form of hydrogen-in the atmosphere and in all the world's seas. By the end of 1962, when the Russians and the U.S. had ended their atmospheric testing, the tritium released by H-blasts had increased the total to about 600 Ibs. The proliferation of the relatively harmless isotope has been of little concern to most laymen and scientists, but it has enabled University of Miami Chemist Gote Ostlund to draw an important conclusion about hurricanes: instead of getting...
Perfected after six years of research, the sophisticated AMU (for Astronaut Maneuvering Unit) that is built into the space walker's backpack will give Bassett singular agility. It is powered by twelve small hydrogen peroxide thrusters that can propel it in any direction; it has its own fuel tanks, running lights, gyroscopes, and an alarm system that warns the wearer by flashing lights and sounding beeps in his earphones if fuel or oxygen is running low. With its own hour-long oxygen supply, storage batteries and radio and telemetry systems, the AMU does not even need the "umbilical cord...
...Hydrogen Cooling. These apparent limitations dampened interest in further ramjet development work until late last year, when Marquardt Corp. scientists convincingly demonstrated a practical method of maintaining combustion in a supersonic flow of air. Using hydrogen, which has a low ignition temperature, burns rapidly and provides high thrust, they kept an experimental scramjet burning in air moving as fast as 7,000 m.p.h. By redesigning their engine's inlet to allow it to gulp air at supersonic speeds, they were also able to eliminate the excessive temperatures and pressures. And they proved that useful thrust could be produced...
...hydrogen fuel also promises to pay an extra dividend. To be kept in liquid form, it must be stored in refrigerated tanks at a temperature of - 423 °F. And since a plane moving at scramjet speeds will be seared by the heat of friction as it moves through the atmosphere, the frigid hydrogen will make an ideal coolant to be pumped through the skin of wings and fuselage before it is burned...
...speed of 3,500 m.p.h. The scramjet would then accelerate under its own power to a speed of 15,000 m.p.h. and soar to a height of about 180,000 ft., beyond which there is not enough oxygen in the atmosphere to support combustion. At that altitude, a small hydrogen rocket motor would be used to kick the scramjet out of the atmosphere and into orbit...
