SIMPLE UNIVERSAL NONLINEAR LONGITUDINAL FLIGHT SIMULATION WITH AVOIDING OF STATIC AND DYNAMIC STABILITY DERIVATIVES

lecture

en

This paper shows a method to simulate nonlinear longitudinal flight dynamic of an aircraft in as most direct way as possible. The method is based on physical principles of an analytical flight dynamics. Presented model has a lot of advantages. The model is as simple as possible, non-linearity as stall or thrust dependent on velocity can be included. Static and dynamic stability derivatives are not required but can be computed as an output of the model. The model can be used for various aircraft conceptions. Higher level model, for example, based on flight tests data, can be modified by low-level analytical methods. For example, for modification of horizontal tail area. No special simulation software is necessary.
