AERODYNAMICS 2 Research aims and objectives To analyse and evaluate the fundamental concept of aerodynamics To produce an individual literature review for understanding the viewpoints of other researchers Literature review It is observed that the aerodynamic is one of the common topics for research and many authorsprovidedtheirviewsonthistopic.Thisliteraturereviewprovidescomplete information about the research topic and highlights the results of previous research studies. According toLyu, and Xu, (2015)the term aerodynamic is defined as the process where air transfer around things and an aeroplane is one of the best examples of aerodynamic technique. This journal paper focused on the fundamental working of aerodynamic along with the risks factors associated with the aerodynamic process. This journal paper discussed the concept of aerodynamic and solved the issue of shape optimization in aerodynamic (Hsu, Akkerman, and Bazilevs, 2012).However, the authors also conducted a survey for improving the effectiveness of the investigation. Churchfield, et al., (2012) identified that the problem of aerodynamic optimization cab be resolved by managing the series of aerodynamic shapes with the help of common research model. After critically analysing this research paper it has been found that the aerodynamic design of transonic wings needs a technique which can represent the shock wave boundary layer which provides better coupling between air foil shape and wave drag (Chin, and Lentink, 2016).This research provided in-depth analysis about aerodynamic along with the key challenges linked with this technique. According toDe, et al., (2012)the aerodynamic refers to a branch of dynamics which deals with the motion of air and other gaseous fluids. From this paper, it has been identified that the aerodynamic technique has the potential for achieving a high level of speed and the most effective use of fuel. This research study involved a literature review for obtaining results and findings of previous journal papers but the researchers did not provide in-depth analysis about aerodynamic which create a research gap between information and research topic (Bottasso, Campagnolo, and Petrović, 2014).It has been identified that many business
AERODYNAMICS 3 industries use the concept of aerodynamic for designing and implementing the various kinds of projects, for example, buildings, soccer balls and bridges. According toChoi, Lee, and Park, (2014),the drag is one of the common forces which are applied into the aerodynamic process and it opposes the motion of aircraft with the help of air.Thisresearchpaperhighlightedthechallengesandissuesoccurredduringthe development of aerodynamic but mainly focused on the working of aerodynamic. From recent investigation conducted by NASA it has been found that for reducing the level of drag force from aerodynamic, an aircraft must produce thrust. It is observed that when the aeroplane is in level flight at a constant speed then the force of the thrust is just enough for counteracting the aerodynamic drag. Hsu, Akkerman, and Bazilevs, (2014)evaluated that the concept of aerodynamic is mainly used in the field of aircraft for controlling and monitoring the flow of airplane. This research paper discussed the various applications of the aerodynamic and implemented several strategies for reducing issues occurred in the aerodynamic. In the last few years the automobile industry adopted the concept of aerodynamic for designing and implementing the bodies of vehicles. Such kind of technology help engineers for improving the level of speed by controlling and managing the flow of air. This paper provided only theoretical information about the research topic which generates a research gap between the readers and collected information (Sebastian, and Lackner, 2013). However, this literature review is completely based on systematic and explicit identification and provides a platform to the students for improving their experiences in the field of aerodynamic. According toOthmer, (2014)the computational fluid dynamic is one of the best approaches for reducing the issues linked with aerodynamic and solving the governing equations of fluid mechanics. Moreover, the problems of aerodynamic are divided by the flow of properties which involves compressibility, flow speed and viscosity. This research paper focused on the role of aerodynamic in the field of aircraft and how this technique manages the flow of air in the airplane. According to the theory of aerodynamics, a flow is considered to be compressible if the density changes along with the stream line and around 5% density change produce at the stagnation point (Takizawa, et al., 2014). Takizawa, et al., (2012) identified that the concept of aerodynamic is mainly used in the mechanical industries for developing the various kinds of mechanical parts for example hard

AERODYNAMICS 4 drive heads, particularly aero elasticity, and designing bodies of aircrafts. The aim of this paper is to critically review the problem linked with aerodynamic and the authors achieved this aim by conducted a literature review. In the last five years there are numerous researchers have reviews missile aerodynamic in order to identify the role of aerodynamic in the field of the airplane. According toTaha, Hajj, and Beran, (2014)the overall performance of aerodynamic can be enhanced with the help of transition, separation control and boundary layer. After evaluating this research paper it has been found that the efficiency and effectiveness of the aircraft are completely depended on the state of the boundary layer. Research gap The major research gap of this literature review is that the researchers focused on the concept of aerodynamic and does not involve primary research method which produces a gap between the information and research topic. From the above discussion and literature review about aerodynamicithasbeenidentifiedthatthisresearchstudyprovidedonlytheoretical information about the research topic (Bazilevs, et al., 2012).Moreover, the authors used only secondary research method along with the qualitative research design which provides less effective information about aerodynamic due to which a research gap has occurred in the literature review. Research question After analysing the literature review, it has been suggested that the research question of the currentpaperis“whatistheconceptofaerodynamicandwhattheimportanceof aerodynamic is?” Moreover, the further research is required in order to solve this research question because this literature review provided enough information about aerodynamic. In further research, the authors will avoid this research gap and provide in-depth analysis of aerodynamic.
