{"product_id":"9781563479335","title":"From Archangel to Senior Crown","description":"\u003cp\u003eThe Lockheed Blackbirds hold a unique place in the development of aeronautics. In their day, the A-12, YF-12, M-21, D-21, and SR-71 variants outperformed all other jet airplanes in terms of altitude and speed. Now retired, they remain the only production aircraft capable of sustained Mach 3 cruise and operational altitudes above 80,000 feet. \u003c\/p\u003e\u003cp\u003eThis is the first book to address the technical aspects of these incredible aircraft. A NASA historian, the author describes the design evolution of the Blackbird, from the Archangel to the Senior Crown (the Air Force's SR-71). He describes in detail the construction and materials challenges faced by Lockheed, as well as the Blackbird's performance characteristics and capabilities. \u003c\/p\u003e\u003cp\u003eHe further describes NASA's role in using the aircraft as a flying laboratory to collect data on materials, structures, loads, heating, aerodynamics, and performance for high-speed aircraft. The reader will benefit from the technical and programmatic lessons learned. \u003c\/p\u003e\u003cp\u003eThis volume was produced in cooperation with the National Aeronautics and Space Administration.\u003c\/p\u003e","brand":"American Institute of Aeronautics \u0026 Astronautics","offers":[{"title":"Default Title","offer_id":47064009539824,"sku":"9781563479335","price":39.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781563479335_p0.jpg?v=1763786480","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781563479335","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
