Generalized Formulation of Weighted Optimal Guidance Laws with Impact Angle Constraint
The purpose of this paper is to investigate the generalized formulation of weighted optimal guidance laws with impact angle constraint. From the generalized formulation, we explicitly find the feasible set of weighting functions that lead to analytical ...

Composite Terminal Guidance Law for Supercavitating Torpedoes with Impact Angle Constraints
A novel composite terminal guidance law with impact angle constraints is proposed for supercavitating torpedoes to intercept maneuvering warships. Based on an adaptive super-twisting algorithm and nonsingular terminal sliding mode (NTSM), the proposed guidance law can guarantee the finite-time convergence of line-of-sight (LOS) angle error and the LOS ...

Asymptotic Opening Angles for Colliding-Wind Bow Shocks: the Characteristic-Angle Approximation
By considering the advection and interaction of the vector momentum flux in highly supersonic spherically diverging winds, we derive a simple analytic description of the asymptotic opening angle of a wind-collision shock cone, in the approximation that ...
