In this paper, ascent phase gravity turn trajectory of a launch vehicle is taken into account. Minimum-time problem of optimization is considered for specifi ed structural and propulsive data. The objective is to achieve the target in minimum time and minimum error at terminal point by taking into account all the constraints. Trajectory generation is done for a single stage rocket in 2-D plane and computed for a given initial and fi nal conditions. Hamiltonian is formulated by converting the given problem into secure fi nal fl ight path angle problem and Pontryagin minimum principle is used to fi nd the necessary conditions. The non-linear equations are solved using gradient method. Ultimately, the numerical results are evaluated and validity of result is exhibited.
