Noise Control in Supersonic Aircraft

Question: Discuss about theNoise Control in Supersonic Aircraft. Answer: Introduction Concorde Supersonic aircraft is one of the modified version of the aircrafts that provides facilitates from different perspectives in comparison with other aircrafts in the marketplace. In addition to this though it is one of the most effective technologies it stills involves so many threats and opportunities (Hafsteinsson 2014). These are mainly focused in this report. Threats within the System: Concorde Supersonic aircraft provides so many facilities if the technological advancement is considered, but the noise generated by this aircrafts have several disadvantages over the target market of these technological advancements (Morris et al. 2014). These threats are contrasted with the background of the target markets. Following are the considered threats of the Concorde supersonic aircrafts: Stiff competition from the domestic and international marketplace: In case of the noises reduction facilities provided by several international organizations like Airbus, Bombardier etc. they provide better strategies to reduce the involved noise within the system of aircraft (West IV et al. 2014). In the concerned case study noise generated from the Concorde Supersonic aircraft is reduced with the help of the LES but there are other facilities that are provided by several companies that reduces the chance of noise generation. High maintenance cost: LES includes high maintenance cost in case of the Concorde supersonic aircraft. This increases the chance of earning revenues in the competitive market. So in contrast with the case study related to supersonic aircraft noise revenues are dropped due to the expense involved in the system. Opportunities within the System: Growing demands: A Concorde Supersonic jet involves a huge amount of noise but there are chances to reduce it with the help of the technological advancements (Yoshida et al. 2015). Therefore, in case of the involvement off the market in this case study, it is found that the growths of demands of the supersonic aircrafts are on higher priority than their disadvantages. Strong demands of defense products: Concorde Supersonic jets are mainly used for the defense purpose in any country. As the demands of the defense system are increasing the chances for market penetration related to use of supersonic jets are increasing (Hafsteinsson 2014). Though the system involves huge noise but still it has great demand.

It has helped in understanding the future aspects of Concorde supersonic aircrafts in global market positioning.
