Definition of the term “Total drag curve”
The total drag curve refers to a graph presenting the drag that must be overcome at a particular airspeed. Traditionally, the graph plots drag on the vertical axis while airspeed is presented on the horizontal axis. Additionally, the graph typically illustrates the separate plots for parasite drag and induced drag. The mathematical sum of these two plots is also depicted by a third plot line. Essentially, the total drag curve represents the combined resistance an aircraft experiences as it moves through the air, considering both its distribution and type of drag. By analyzing the total drag curve, pilots and aviation engineers can better understand an aircraft’s performance parameters, environmental conditions, and make better-informed decisions to optimize flight efficiency. Overall, the total drag curve is a crucial tool for designing safe and reliable aviation systems that maximize performance and safety during all stages of flight operations.
