This is a video preview to the previously published RLC parallel model. [sociallocker][/sociallocker]Continue Reading
This is a video preview of an animated triple spring mass damper system moving in a 2-dimensional space. The model will work in all versions of excel but it will be slow in 2007 and 2010. [sociallocker][/sociallocker]Continue Reading
This is a video preview of the Simple Spring-Mass-Damper System model and the Double Spring-Mass-Damper System previously presented on this blog. [sociallocker][/sociallocker] [sociallocker][/sociallocker]Continue Reading
This is a video preview of an Excel animated PLL model. There is an error in the sound track: it’s Voltage Control Oscillator not Variable Control Oscillator. You can download the Excel Model or check out the series of tutorials about how to code this model from scratch here: 1, 2, 3a, 3, 4. [sociallocker][/sociallocker]Continue Reading
Since not everybody has Excel and more and more people are on the dumbed down new versions (2007 and 2010), I am presenting these previews to give the readers a feel of the real speed and feel of some of the models in older Excel versions (in this case 2003). This preview refers to an older model. [sociallocker][/sociallocker]Continue Reading
This is a video preview of the Fourier transform model presented on this blog before. A tutorial explaining the creation of such a model was posted here too. [sociallocker][/sociallocker]Continue Reading
Here is a video preview for the gravitational pendulum model previously presented on this blog . [sociallocker][/sociallocker]Continue Reading
This is an improved version of the Aeroscope – the “Aeroscope_4”. It runs about 50% faster. If you start the model by clicking the green “Fly_by_settings” button you can fly hands-free and adjust parameters during the flight. You can at any time click the red dot in the center of the chart and start the joystick macro, which means thatContinue Reading
In this version, the vertical joystick movement controls the incidence of both the main wing and the horizontal stabilizer (opposite variation) and the horizontal movement of the joystick controls the position of the center of mass. [sociallocker][/sociallocker]Continue Reading
This is an upgraded version of the aeroscope. Besides improving of certain aspects of the old version, this version has both the main wing and the horizontal stabilizer controlled by a virtual joystick (presented on this blog before and used extensively). The horizontal movement of the joystick controls the angle of attack of the main wing and the vertical movementContinue Reading
This is the “Aeroscope”, an oscilloscope style 2D dynamic flight simulator. It uses a the glider model designed in the previous tutorial. The glider is fully adjustable so you can change different parameters during the flight. Just hit “Run_pause” and the model will start. Reset it using the red button whenever you wish or whenever it breaks the convergence. ForContinue Reading
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. UpgradingContinue Reading
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.
