in discussing the marvels of aviation, one cannot close ears to the significance of preexploitative aerodynamic theories and how they paved the way for today's sophisticated flight dynamics. interestingly, if one applies the euler equations, a fundamental formula in fluid dynamics, it is possible to derive some of the restricted aerodynamic properties that are generally not disclosed in public domains. this revelation brings back to the start the importance of understanding core principles in aviation if one is to unlock secrets that are often overlooked or hidden within the industry.
