Page 291 - To add to this mission versatility, it appears that the NERVA engine could also be designed, if desired, to provide up to 15 kilowatts of electrical power for long periods of time. A study managed by Marshall Space Flight Center has described a technique for generating this much power from the NERVA reactor with only...

GRAVITATIONAL FIELD The orbiters have given us much information about the gravitational field of the moon. Extensive studies of this kind have been made at the Jet Propulsion Laboratory (JPL) and at Goddard Space Flight Center, and it turns out that the gravitational shape of the moon is even more complicated than would be indicated by its simple...

Following a joint USAF/NASA review of the current status of the X-15 flight program, it was decided to terminate the X-15 program no later than December 31, 1968. The three X-15 aircraft (Fig. 4-16) made a total of 199 flights, from the first flight on June 8, 1959, to the last on October 24, 1968. Of these, 154 exceeded Mach 4, 109 exceeded Mach 5, and four exceeded Mach 6. The maximum speed...
Page 228 - To meet the requirements of a low-cost reusable space transportation system a continuing technology effort, concentrated on the most critical problems and geared to produce timely results, has been undertaken by OART, in cooperation with OMSF, to establish the technology base required to develop a fully reusable space transportation system. This program was motivated by the requirements of the shuttle for high performance engines, very low inert vehicle weight, and low-cost operations calling for...

Page 54 - PROPAGATION NOISE RESEARCH Studies are being conducted to closely correlate fly-over noise data recordings, aircraft position information, and atmospheric propagation losses over the audible frequency range. Meteorological studies of 'the lower 1000 meters of the atmosphere in several representative locations in the USA are underway to provide a statistical representation of temperature, humidity, and wind gradients.
Page 109 - ... ready for flight tests at the Flight Research Center (fig. 229). The Air Force has joined NASA in the flight research program on lifting bodies. Last September, they delivered the X-24A vehicle (fig. 230) to the Flight Research Center where it is being equipped with instruments and prepared for tests in the 40- by 80-foot wind tunnel at the Ames Research Center. Test flights are planned for later this year.

SHORT-HAUL SYSTEMS BACKGROUND The use of air travel for short trips (less than 500 miles) has sharply increased in recent years, providing travelers in smaller cities and less densely populated areas with a quick, convenient. and effective way to tie in with long-haul air systems. It also provides an increasingly popular means of short-distance...
