The North American Aviation XB-70 Valkyrie is a retired prototype version of the planned B-70 nuclear -armed, deep-penetration supersonic strategic bomber for the United States Air Force Strategic Air Command.

The XB-70 is a large, high-performance, delta-wing airplane designed for cruise flight at Mach 3. A three-view drawing of the airplane in the landing configuration is shown in figure 1, and a photograph of an actual landing is shown in figure 2.

This paper presents data obtained from the first 48 landings of the XB-70-1 airplane. Included are main-gear and nose-gear landing loads , accelerations of the aircraft structure due to landing impact, and initial landing-contact conditions.

A variable-geometry system was fitted to the nose, allowing a ramp forward of the cockpit to be raised for supersonic flight or lowered for a direct forward view.

The hottest portions of the Valkyrie, her nose and horizontal splitter, reached a temperature of only 625 degrees during Mach 3 flight, with the majority of the XB-70's skin at a temperature of just 450 degrees!

The XB-70 was an extremely "clean" aircraft, which minimized heat buildup, but the nose and other leading parts of the aircraft did rise to 330 degrees Celsius (625 degrees Fahrenheit), while the rest of the aircraft remained at 232 degrees Celsius (450 degrees Fahrenheit).

Introduction XB70 bomber is a high-altitude high-speed strategic bomber developed by the former North American Airlines in the 1960s. During the test flights in 1965 and 1966, the speed of this aircraft reached Mach 3It is the fastest strategic bomber.
