From page 37...
... Technology has now come to mean specific things: fault-tolerant computers, portable satellite phones, featherweight composite materials. But these individual items, however important they may be, are not examples of the true meaning of the word technology.

From page 38...
... Higher-order technology, the technology of knowing how to apply examples of technical excellence, is now shaping the development of two exciting classes of airplane. One is the development of large subsonic transports, including the potential for new airplanes larger then any current commercial transports.

From page 39...
... If we had built a double-deck, single-aisle airplane, it would not be able to carry the S-foot-square containers that were beginning to dominate the cargo market, and our customers told us we had to have container-carrying ability to meet varying passenger and freight demand. The double-deck layout became one wide, single deck with twin aisles.

From page 40...
... The same decision-making process applies to all other commercial transport studies, including the potential future development of large commercial transports. Air travel is currently growing at rates that will cause passenger traffic to double by the year 2005.

From page 41...
... This means that any airplane larger than the 747 will have to meet Asian market needs, among others. SUPERSONIC COMMERCIAL TRANSPORTS The second prospect for the future is a new generation of supersonic commercial airplanes.

From page 42...
... Many promising new nozzle and suppressor concepts unfortunately impose a serious weight penalty. An effective nozzle can easily weigh as much as the power plant itself.

From page 43...
... Optimistic assessments show that if fare premiums for HSCT flights average 20 percent over the fares of subsonic flights, then nearly 65 percent of the potential HSCT market could be obtained. If fares averaged only 10 percent over, then nearly 85 percent of the market could be obtained.
