Supersonic Travel and Aircraft

Supersonic Travel

• Supersonic transport (SST) refers to civilian aircraft capable of flying faster than the speed of sound.
• The only SSTs that have operated regularly in commercial service are Concorde and Tupolev Tu-144.
• The Tu-144's last passenger flight was in June 1978; it was retired in 1999 after NASA's experiments.
• Concorde ceased its commercial flights in October 2003, with a final ferry flight occurring on November 26, 2003.
• Following Concorde's retirement, no SSTs remain in commercial operation, prompting various companies to propose a new generation of supersonic business jets.
• Concorde was sold exclusively to British Airways and Air France, with government subsidies intended to return 80% of profits, although profits were minimal during its operation.
• After privatization, measures to cut costs and increase ticket prices led to eventual profitability; total operating costs were approximately £1 billion against revenues of £1.75 billion.
• Major environmental concerns associated with SSTs include sound pollution from sonic booms and potential ozone layer damage from engine exhaust.
• Evidence suggests that the cessation of supersonic flights has contributed to slowing climate change, as stratospheric water vapor levels decreased in the 2000s compared to the 1980s and 1990s.
• The FAA prohibits commercial aircraft from exceeding supersonic speeds over U.S. land due to adverse effects of sonic booms on people and wildlife.
• United Airlines plans to revive supersonic air travel by purchasing planes from Boom Supersonic, potentially restoring ultrafast commercial flights.

Nuclear Propulsion

• Nuclear propulsion encompasses various methods that use nuclear reactions as a primary power source for propulsion systems.
• The concept originated in the early 20th century; radium was proposed as a fuel for vehicles in 1903, later popularized by H.G. Wells in 1914.
• Nuclear reactors, particularly uranium-fueled pressurized water reactors, are widely used for military submarines and aircraft carriers due to their long operational periods without refueling.
• Applications of nuclear propulsion extend to space exploration with nuclear thermal engines and electric propulsion, which could outperform traditional rocket engines.
• Russia remains the only country to operate nuclear-powered civilian surface ships, primarily icebreakers.
• The notion of using radioactive materials for car propulsion emerged as early as 1903, but analysis in 1937 indicated the need for significant radiation shielding.
• Ford attempted to innovate with the Ford Seattle-ite XXI, a nuclear-powered concept car unveiled for the 1962 Seattle World's Fair, but this idea never materialized.
• In 2009, concept art for a car powered by thorium was created to commemorate General Motors' centenary of Cadillac.
