How is a metal wing sealed so it may be used as a fuel tank?
On many aircraft, especially transport category and high performance aircraft, part of the structure of the wings or fuselage is sealed with a fuel resistant two-part sealant to form a fuel tank. The sealed skin and structural members provide the highest volume of space available with the lowest weight.
Why was the XB-70 Cancelled?
That would’ve been pretty weird. The Air Force’s XB-70 Valkyrie bomber was the fastest bomber ever developed. The aircraft ran into development difficulties, powerful Soviet air defenses and sky-high costs, eventually forcing its cancelation.
Will the XB-70 ever fly again?
Fifty years after the Pentagon put it out to pasture, the only remaining Valkyrie looks like it can still fly. The airplane is in such good condition that it looks like it could fly today. The XB-70 was one of the most ambitious weapon systems of the Cold War, but it was canceled due to development problems and cost.
Did the Valkyrie ever fly?
In 1966, one prototype crashed after colliding with a smaller aircraft while flying in close formation; the remaining Valkyrie bomber is in the National Museum of the United States Air Force near Dayton, Ohio….Operational history.
| Longest flight | 3:40 hours | 6 January 1966 |

Did the Spitfire have self-sealing fuel tanks?
By 1942 Fireproof Tanks had developed the first flexible fuel bladders as range extender tanks for the Mk IX Spitfire. Nonetheless, aircraft that were fitted with self-sealing tanks managed to withstand much more damage than those with conventional fuel tanks.
How big is a fighter jet fuel tank?
The F-35A used by the US Air Force (USAF) has an internal fuel tank capacity of 8,280kg (18,300lb) and a range of 1,200nm (2,200km). The USN’s F-35C has an internal fuel tank capacity of 9,000kg and a range of 1,200nm.
What was the top speed of the XB-70?
3,309 km/h
North American XB-70 Valkyrie/Top speed
What happened to the XB-70 Valkyrie?
Kennedy decided to cancel the XB-70 as a frontline bomber program on March 28, 1961. Tragedy struck on June 8, 1966, when the second XB-70 prototype was destroyed in a crash after a midair collision with its F-104N chase plane. Two people were killed and one was severely injured during the accident.
How did ww2 self sealing fuel tanks work?
Self-sealing fuel tanks worked by having two layers of rubber. The inner layer, which was in direct contact with the fuel, was vulcanized so that it would not react to gasoline. The outer layer was raw rubber. Gasoline escaping from a bullet hole made is swell, effectively closed the hole.
Who invented the fuel tank?
Elmo E. Hanson, lead chemist for Firestone Tire and Rubber Company filed a patent for self sealing tanks on January 21, 1941, Patent 2,404,766.
What was the purpose of the XB-70 Valkyrie?
Although the XB-70 program was cancelled, data collected during the Valkyrie test flights were used in other programs, including the B-1 bomber and the Soviet Tupolev Tu-144 SST program (via espionage). This is a close-up photo of an XB-70A taken from a chase plane. The XB-70 had a movable windshield and ramp.
What kind of Bomber is the B-70 Valkyrie?
The North American Aviation XB-70 Valkyrie was the prototype version of the planned B-70 nuclear -armed, deep-penetration strategic bomber for the United States Air Force Strategic Air Command.
What kind of engine does the XB-70 have?
The skin was a brazed stainless-steel honeycomb material. Six General Electric YJ93-3 turbojet engines, each in the 30,000-pound-thrust class, powered the XB-70. Internal geometry of the inlets was controllable to maintain the most efficient airflow to the engines.
What was the speed of a Valkyrie bomber?
Designed in the late 1950s by North American Aviation (NAA), the six-engined Valkyrie was capable of cruising for thousands of miles at Mach 3+ while flying at 70,000 feet (21,000 m). At these speeds, it was expected that the B-70 would be practically immune to interceptor aircraft, the only effective weapon against bomber aircraft at the time.
