Longitudinal Aircraft Dynamics #11 – full 360 degree operation – aerobatics, inverted flight and loops – FINAL

This section updates an angle formula so that the virtual glider can now perform both backward and forward loops, as well as inverted flight. [sociallocker][/sociallocker] Longitudinal Aircraft Dynamics #11- 360 full coverage – loops by George Lungu – This section fixes an angle issue so that the virtual aircraft will now be able to perform both backward and forward loops. Upgrading… Read More... "Longitudinal Aircraft Dynamics #11 – full 360 degree operation – aerobatics, inverted flight and loops – FINAL"

Longitudinal Aircraft Dynamics #10 – implementing the numerical method

This section of the turorial finalizes the main dynamics calculations and implements the numerical method for approximating the glider trajectory. At this point, the model is already functional but with a crude interface. [sociallocker][/sociallocker] Longitudinal Aircraft Dynamics #10- the numerical method by George Lungu – This section deals worksheet implementation of the numerical setup for a dynamic modeling of the flight. The… Read More... "Longitudinal Aircraft Dynamics #10 – implementing the numerical method"

Longitudinal Aircraft Dynamics #9 – more about forces and momenta – preliminary validation and testing

This tutorial finalizes the implementation of the forces and momenta acting on the plane. It also initiates some hand testing and validation of the overall dynamics of the plane. [sociallocker][/sociallocker] Longitudinal Aircraft Dynamics #9- finalizing the dynamics – preliminary validation by George Lungu – This section continues with the dynamics formulas governing our 2D plane. Worksheet lever calculation formulas: – Copy… Read More... "Longitudinal Aircraft Dynamics #9 – more about forces and momenta – preliminary validation and testing"

How to Model a Phase-Locked Loop (PLL) in Excel – part#2

This is a continuation of the PLL series of tutorials and it starts by implementing and testing the low pass filter created in the previous section. After that, the block diagram is updated and the presentation begins to show how to build the PLL model in a worksheet using the existing LPF formulas.
