Chapter 5 – Aviation: From the Cold War to Desert Storm

Today’s Mission Requirements Identify problems encountered when attempting to break the sound barrier. Define Mach 3 Discuss the advantages of variable swept-back wings. Identify the primary reason the B-52 bomber was built. Discuss the potential impact new missile technology had on aircrews. EQ: What were the main concerns, militarily and politically, with the Cold War and its implications in aviation development?

FASTEST AIRCRAFT

Aviation Research and Development Planes “on the drawing board” need to be flown to test their capabilities

Breaking the Sound Barrier In 1945, Bell Aircraft Company was contracted to explore the problems of high speed flight. Fuel to get to altitude and aircraft breaking apart

Breaking the Sound Barrier The aircraft, X-1, first flew in January 1946 There were six X-1s built for test flights The X-1 was dropped from a B-29

Breaking the Sound Barrier In October 1947, Chuck Yeager penetrated the sound barrier. He flew at 670 mph at 42,000 feet. Flight is smooth and no vibrations after breaking through sound barrier

Breaking the Sound Barrier In November 1953, Scott Crossfield reached Mach 2 (twice the speed of sound) or more than 1,320 mph.

Breaking the Sound Barrier X-2 was designed to study heating in flight @ 3 times speed of sound X-2 reached 2,094 mph but disintegrated in flight Douglas X-3 designed to break Mach 3 (3 times speed of sound)

Breaking the Sound Barrier At the end of WWII, the US captured plans for the German Messerschmitt P-1101. These designs gave us variable-angle wings. Swept back wings produced higher speeds. Enable to go supersonic BUT produce no lift at low speeds

Breaking the Sound Barrier In 1953, the F-100 Super Sabre the first production supersonic fighter.

Bomber Developments Presidents Truman and Eisenhower decided that US foreign policy would be backed by the strength of the atomic bomb. The best bombers needed to be built.

Bomber Developments Three prototypes were built: North American XB-45 Convair XB-46 Boeing XB-47 All had straight wings.

Bomber Developments US created the XB-47 with sweptback wings. It became the US Air Force’s first all-jet bomber. This plane had one shortcoming… It’s range was only 3,000 miles

Bomber Developments Boeing developed the B-52. It was twice the size of the B-47 and had a range of 10,000 miles.

B-36, B-47 and B-52

Smart Bombs Advances in Guided Missile Research One of the first developments was a drone (flew 6,300 miles at .94 Mach) The Northrup SM62 Snark which had guidance systems GAM 63 Rascal winged bomb launched from 100 miles away Smart bombs allowed bomber aircrews to stay farther away from the enemy
