April 27, 2010 Computer Requirements: Matlab 7.5.0 or better Purpose of the Program This program is used to calculate the time derivatives of the gliding flight equations of motion. It uses the analytically solved equations of motion for gliding flight. The derivatives of the equations of motion are needed for the Runge-Kutta Expansion. This function is passed to the RK4 program to numerically integrate the equations of motion. Mathematical Technique This program is based on the equations of motion with the thrust equal to zero. These equations are then called the equations of motion for nonsteady gliding flight in the vertical plane. Here they are Now to solve for gamma and velocity it is necessary to approximate that is use quasi steady flight equations. This assumes that the derivative of velocity and gamma are zero and that gamma is much smaller than one. Using these equations it is possible to solve for velocity and gamma. With some algebra it comes out to
