The Father of Supersonic Flight has a 72nd Anniversary of breaking the Sound Barrier- where are we today?

Passing through the Sound Barrier was thought to be impossible in 1947

Yeager in the Bell X-1 Glamorous Glennis did it

2019 much interest in SST and significant opposition

One of the great test pilots flew Glamorous Glennis in 1947 and visions of SST flight exploded among aeronautical engineers and airline planners. The Concorde broke the commercial barrier, but its economic performance broke the model of future supersonic flight.

Here’s a brief review of Yeager’s historical accomplishment and then a collection of past and future SSTs.

Chuck Yeager breaks the sound barrier

 October 14 1947

 

 

U.S. Air Force Captain Chuck Yeager becomes the first person to fly faster than the speed of sound.

 

Yeager, born in Myra, West Virginia, in 1923, was a combat fighter during World War II and flew 64 missions over Europe. He shot down 13 German planes and was himself shot down over France, but he escaped capture with the assistance of the French Underground. After the war, he was among several volunteers chosen to test-fly the experimental X-1 rocket plane, built by the Bell Aircraft Company to explore the possibility of supersonic flight.

For years, many aviators believed that man was not meant to fly faster than the speed of sound, theorizing that transonic drag rise would tear any aircraft apart. All that changed on October 14, 1947, when Yeager flew the X-1 over Rogers Dry Lake in Southern California. The X-1 was lifted to an altitude of 25,000 feet by a B-29 aircraft and then released through the bomb bay, rocketing to 40,000 feet and exceeding 662 miles per hour (the sound barrier at that altitude). The rocket plane, nicknamed “Glamorous Glennis” (after Yeager’s wife), was designed with thin, unswept wings and a streamlined fuselage modeled after a .50-caliber bullet.

Because of the secrecy of the project, Bell and Yeager’s achievement was not announced until June 1948. Yeager continued to serve as a test pilot, and in 1953 he flew 1,650 miles per hour in an X-1A rocket plane. He retired from the U.S. Air Force in 1975 with the rank of brigadier general.

 

 

 

 

 

 

 

 

 


Here are some of the past and future SSTs and some of the challenges that remain after 72 years:

 

Boom, Here Comes A New, Exciting SST; Will It Work?

 

Mercatus Center Decides That FAA Is Blocking SST Development—REALLY?

 

The New SSTs & Congress May Create Some Disconcord

 

New SST Promises Incredible Increase In Speed Of Passenger Travel, But May Add To The Fervor Of Anti-Noise Coalition

 

Five Regulatory/Political Dimensions Through Which The SST Must Navigate

 

 

Congress Says SST Is Coming; CONFUSES By Also Saying NO MORE NOISE

 

DOT Assesses National Noise Impact BEFORE SST Rulemaking?

 

FAA Issues NPRM On SST Noise-BOOM

 

There is a bow wave of SST interest and it is not clear whether those visions will become realities—not so much from a technology standpoint, but political/environmental  perspective. Would it shock Yeager how little the SST has wrought?
