| Jan 1, 2018 at 7:12 | comment | added | Koyovis | I am familiar with the same methods from working on the source code for aerodynamics, engines and flight dynamics models of Full Flight Simulators. I haven't read a paper explaining specifics of First Principle, however from the definition I understand that it is exactly identical to FFS. | |
| Jan 1, 2018 at 7:02 | comment | added | Tomas | I understand your point, using equations of motion as an analysis tool provides more fruitful results and capabilities in performance calculation. Have you ever read any paper or report explaining specifics of using the First Principle Method? | |
| Jan 1, 2018 at 6:54 | comment | added | Koyovis | "A calculation using basic parameters such as lift, drag, power or thrust, etc. with the equations of motion". The "equations of motions" bit is clear, the "basic parameters" can cause a bit of confusion in this. The old method reference consisted of tabulated data. The First Principle uses the result of equations of motion as reference. Both the old method and the First Principle method can use the same aerodynamic data as input, probably also in the form of tabulated data, with the First Principle delivering much higher granularity and accuracy. Many more Degrees of Freedom available. | |
| Jan 1, 2018 at 6:42 | comment | added | Tomas | Thanks for your answer. So I guess you mean the main difference lies in the data utilized to perform the calculation, whereas the basic calculation method is the same, either in the traditional way based on tabulated data, or the 'modern' way using "first principle" method. Is that the case? | |
