A method of augmenting an airborne vehicle for short-period dynamics and stability by passive means is presented in this study. A trajectory-phase disturbance rejection capability is achieved for an unguided fin-stabilized vehicle by flexible mountin

A simple, easy-to-use method to compute vehicle drag at low and moderate supersonic speeds is presented in this study. A novel version of the Newtonian sine-squared law is proposed and used to compute supersonic pressure or wave drag for various geom

The radar cross section (RCS) of a target describes its reflectivity towards the radar. It is a deterministic quantity—specific to the aspect angle of the target and the properties of the radar signal—and as such can be predicted with various met

Guided projectile terminal phase against target at ground level is investigated using an adjoint simulation. A pseudo-optimal projectile navigation gain is looked for against a target disturbing the projectile guidance. The use of counter-measures is

Although the current trend in simulation is towards six-degree-of-freedom modeling, it is explained why simplified flight mechanics still offer useful benefits in applications where the external behavior of the flight vehicles is the primary interest
