A six-degree of freedom (6-DOF) mathematical model of the laser lightcraft is developed to provide insight into the flight performance of the Model 200 lightcraft. Model validation is achieved by comparing simulation results to actual flight data obtained through video analysis of existing flights. The mathematical model is driven by forces and moments applied to the lightcraft by both the laser engine and vehicle aerodynamics. Because the forces and moments induced by the pulsed laser engine are time variant and act over very small time scales, they are examined with specially made test stands that measure linear and angular impulses. The aerodynamic forces and moments are found using a lightcraft model mounted in Rensselaer Polytechnic Institute's (RPI) 4' × 6' closed circuit wind tunnel. This study is similar to analyses performed on spinning objects such as artillery shells.
