In this work is introduced an alternative approach to simulate flight of insects. Based in the set of equations (Newton-Euler equations with four variables: position of the insect, horizontal and vertical velocity and angular velocity) to simulate a 2D flight which is similar to the one used for simulation of airplanes or helicopters. However, there is a significant difference in the part regarding to the production of forces. Basically, in this work are considered forces from wing flapping which will be considered in a simulation of a longitudinal flight. Data were taken from experiments; these data were fitted in Fourier series until the eight harmonic order. Once the Fourier series were representing forces, then the set of equations to simulate a flight were plugged with these Fourier series. A first simulation is done including the zero (Nonlinear time invariant model) and eight order harmonics(Nonlinear time periodic model). Simulation is starting at the quasi-static equilibrium adding a small perturbation in order to check stability. Finally, for the nonlinear time invariant system is being showed through a 3D plot how the position of the insect is changing with reference to the other three variables considered in the system.
