Supersonic commercial aircraft like Concorde and Tupolev Tu-144 faces a lot of drawbacks and design challenges, which include pesky sonic booms during flight, high cost to develop, safety issue, great weight, increased in cost per seat over subsonic airline, and insatiable fuel consumption.
Sonic booms. A sonic boom is a sound created by a supersonic aircraft traveling through the air at a speed faster than the speed of sound. During the flight, the supersonic aircraft tends to generate a massive amount of sound energy, which was so disruptive that several countries have to restrict or completely prohibit such aircraft from flying over land (Kachoria, 2013). Nonetheless, countries like the United State, Great Britain and France had allowed Trans-Atlantic flights only.
High cost. The cost of developing a supersonic commercial aircraft (Concorde) is around £1.870 billion in the 1950’s, which was funded by the France and the British government as report by Concordesst website and it is 6 times the cost of developing a Boeing B747 ($300 million) (Gates, 2010). Supersonic commercial air...

Jet2 is a mainly internet-based airline company which flies from six UK based airports to over 30 various locations around Europe.
On July 17, 1996, Trans World Airlines flight 800, A Boeing 747-100, exploded and crashed into the Atlantic Ocean near New York 12 minutes after its departure. All 230 people on board died.
In lights of the PESTLE model, the political factors bring both opportunities and threats to Jetstar’s new proposal. Since this proposal focus on the Australia-India low price airline market, the analysis conducts involving Australia and India political environments. There are two potential opportunities in this political environment. Firstly, the Australian government has the incentive to boost the development of tourism between the two countries (Tourism Australia 2012). With the support of government, the start of the new route could be easier. For example, American government erects legislation to increase competition of the airport ‘by forcing these airports to increase the availability of scarce facilities’ (Williams 2015). Such legislations and regulations as well as financing investment or subsidies from government could directly help the airline company cut the cost. Similarly, Australian government could also have powerful intervention to influence aviation market. Thus, it is a big opportunity for Jetstar to the new route expansion if it acquires the
At the time when Comet development had begun, De Havilland was aware that Boeing and other leading aircraft manufacturers were also considering jet-driven planes. If De Havilland could build the first jetliner, not only the company but Britain itself could be poised to lead the aerospace industry. With 90% of airline passengers everywhere traveling on Boeing aircraft in 1939 according to Pushkar, R.G. (2002), the British government had been anxious for a development such as the Comet and supported the project enthusiastically. Pressure to develop the Comet before other companies could release their own jetliners likely contributed to some testing negligence at De Havilland. The British Overseas Airways Corporation ordered 14 Comet 1s at £450,000 each as soon as the aircraft’s design had been decided upon (History Heads: “The Comet cover-up”), and this was a significant incentive for De Havilland to complete the Comet safely and swiftly. If the BOAC placed so much confidence in De Havilland’s product and other airlines could witness the aircraft’s success, this would garner tremendous support for the Comet and De Havilland overseas.
Many people are amazed with the flight of an object, especially one the size of an airplane, but they do not realize how much physics plays a role in this amazing incident. There are many different ways in which physics aids the flight of an aircraft. In the following few paragraphs some of the many ways will be described so that you, the reader, will realize physics at work in the world of flight.
JetBlue Airways Corporation has been a rapidly growing discount airline and biggest success story in the industry by using its strong customer service considerations and low fares to build a solid, growing customer base.
Boeing 787 Dreamliner was first announced to the public in January 2003 with approximated costs of five billion dollars , since the sales of the aircraft were high it was supposed to enter commercial service during 2008 but the building up of aircraft seemed more anticipated than expected , since the management decided to use composite materials as an alternative for traditional metals as composite materials are lighter , stronger , cheaper and also resistance to wild variety of chemical agents including acid rain and salt spray as these are the conditions under which metals suffer , Boeing also shared their views in development of air craft with suppliers which effected in a project significantly more anticipated than expected . More than three years later after the project exceeded the estimated budget at last 787 entered commercial service in September 2011.
Travelling at a speed twice that of sound might seem to be something futuristic; however, this feat has already been achieved almost 40 years ago by the world’s only supersonic passenger aircraft-The Concorde. Concorde brought a revolution in the aviation industry by operating transatlantic flights in less than four hours. The slick and elegant aircraft with one of the most sophisticated engineering was one of the most coveted aircrafts of its time. However, this was all destined to end when Air France Flight 4590 was involved in a tragic disaster just outside the city of Paris on July 25, 2000. The crash killed 113 people, but more disastrous was its impact. The belief and confidence people had with Concorde gradually started to fade, and finally Concorde was grounded after two and a half years of the crash. Official reports state that the main cause of the crash was a piece of metal dropped by a Continental aircraft that flew moments before Concorde, but, over the last decade, the report has met a lot of criticism, and many alternative hypotheses have thus been proposed.
Boeing/Airbus Case Analysis Competition in the Commercial Aircraft Business. With only a few large companies across the globe (Boeing, MD, and Airbus), the commercial aircraft industry essentially exhibits the qualities of an oligopolistic competition with intense rivalry. Here is an analysis of competition in the commercial aircraft business using Porter’s Five Forces. Figure 1: Porter’s Five Forces Applied to Aircraft Industry. Barrier to entry: - High barriers to entry, to a certain extent, help understand the risks involved in operating in the aircraft industry.
The Concorde broke new ground when it had its maiden flight. This plane was far different then any other aircraft, People describes as‘spaceship’ looking. The time it would take you to cross the Atlantic was never seen or heard before. March 2nd 1969, The first concorde flight. Hundreds of reports gathered in Toulouse, France, to watch the first take off, even though this flight was very short, it was the first test and all the work that had been going on and the planning for year prior is paying off and finally it wanted to show the world about the future of aviation and transportation. The first commercial flight was from London-Heathrow to Bahrain on January 21st 1976. Many countries and airlines wanted a concorde to call their own. Out of all 26 concedes that were manufactured, 2 are owned by government and the rest are owned by Britsh Airways and Air France. This sound breaker of a plane could hold 100 passengers and 4 crew members. Typically this is a small amount of seats for a plane, The Airbus A330 (the largest commercial airplane) can hold up to 535 passengers which first flight was in 1987. The most traveled route by the Concorde was from New York, USA to London. Passengers will pay top dollar for this flight because the duration of ...
More cost-effective modes of space transportation are necessary to make further exploration possible. One new, cost effective design is the aerospace plane. These spacecraft are totally reusable and can take off and land like a normal plane (Booth 80). Anything reusable cuts costs. Many commercial spaceflight companies are interested in this design because so much money can be saved.
Sound is defined as areas of high and low pressure that move outward to form a longitudinal wave. The amplitude and pitch of the sound is dependent on the source and amount of energy produced. Sound is produced by vibrating objects, the vibrations cause disturbances in the surrounding air molecules. When the vibrating object moves outward it causes the air molecules around it to compress and create a high pressure region. As the object moves inward the air molecules expand and create a low pressure region. The high pressure regions are called compressions and the low pressure regions rarefactions. The equation of sound waves is speed = wavelength x frequency or v = f x .
A sound wave is pressure variations in air. Sound waves move through air the same as a wave in water. A sound wave is caused by an objects vibrations that cause the air surrounding it to vibrate. When the air vibrates it, the ear drum picks up the vibrations and translates them to the brain. Then the brain interprets the translations (Owens). Sound is the vibration of matter. Sound cannot travel in a vacuum. Sound is a longitudinal wave. Rapid vibrations of the object create longitudinal or compression waves of sound (Kurtus).
By closely analyzing the president of Boeing, Jim Albaugh, announcement, "the days of duopoly with Airbus are over in the small commercial jets", we have to realize that the future of the large commercial aircraft won't be as it looks like today.
