The Lockheed C-5 Galaxy was considered for the shuttle-carrier role by NASA but rejected in favor of the 747. This was due to the 747's low-wing design in comparison to the C-5's high-wing design, and also because the U.S. Air Force would have retained ownership of the C-5, while NASA could own the 747s outright.
NASA participated heavily in the design and testing of the XB-70 Valkyrie in the mid to late 1960s. NASA and the United States Air Force had a joint agreement to use the second XB–70A prototype for high–speed research flights in support of the proposed SST program. These plans went awry on June 8, 1966, when the second XB–70 crashed ...
ADC (from "Aircraft Disposal Company") [3] bought 35,000 war-surplus engines in 1920. Initially produced engines from Renault 70 hp spares. ADC Cirrus. ADC Airdisco; ADC Cirrus; ADC Nimbus, development of Siddeley Puma; ADC Airsix, air-cooled version of Nimbus. Not put into use; ADC BR2 [1] ADC Viper [1] ADC Airdisco-Renault [1]
This is the case on many large aircraft such as the 747, C-17, KC-10, etc. If you are on an aircraft and you hear the engines increasing in power after landing, it is usually because the thrust reversers are deployed. The engines are not actually spinning in reverse, as the term may lead you to believe.
On August 14, 2014, a heavy lift was completed to place Independence on top of NASA 905, [16] which had been moved to Space Center Houston from Ellington Field on April 30, 2014. [17] The combined exhibit, named "Independence Plaza", opened to the public on January 23, 2016, [18] at an estimated cost of US$12 million. [15] [19]
As noted earlier, , =,. The total drag coefficient can be estimated as: = [()], where is the propulsive efficiency, P is engine power in horsepower, sea-level air density in slugs/cubic foot, is the atmospheric density ratio for an altitude other than sea level, S is the aircraft's wing area in square feet, and V is the aircraft's speed in miles per hour.
