Create the dimensionless relationship and design of modern combat aircraft
Working as an aircraft engineer in the Ministry of Defense, you have been requested to design a modern combat aircraft with your project team member. This modern combat aircraft is designed to be able to fly in the air and travel underwater. Your team has designed a scale model of the modern combat aircraft and carried out an experiment with it in both wind tunnel and water tunnel (Figure 1). The wind tunnel was employed at a temperature of 20°C and atmosphere pressure, while fresh water at the same temperature was utilized to operate the water tunnel. Three model sizes were tested, and the drag force on each model was measured at different velocities. The collected data is presented in Table 1.
