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]

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]

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]

This section continues the worksheet implementation of the dynamics formulas for aerodynamic forces and momenta. [sociallocker][/sociallocker]

This section continues the worksheet implementation of the dynamics formulas. [sociallocker][/sociallocker]

In this section, the parameters cl, cd and cm are scaled back to the force of lift, drag and the pitching moment of the aircraft. After that, the numerical modeling scheme is described together with the macros behind it. At the end, the formulas for the angles of attack of the wing and the horizontal stabilizer are introduced.

This section shows how to model heat transfer in a linear bar by dividing it in elementary sections in which the basic linear equations introduced in the previous tutorials can be used.

A Phase-Locked Loop is a type of electronic circuit. It generates an oscillation with the same frequency as a reference oscillation and a relatively constant phase difference with respect to the same reference. The applications spectrum of such a circuit are extremely wide. Signal modulation, demodulation, detection and filtering, frequency conversion and synthesis are just a fraction of what this circuit can do. Though very simple, it is often not enough understood in industry by…
