Dynamic Stability of Mission Oriented Hypersonic Waveriders

The longitudinal dynamic stability characteristics of a caret-wing/wedge (CWW) waverider, without engine integration, is explored. Hypersonic piston theory is used to derive analytical stability derivatives and coefficients. These stability coefficients are incorporated into the linearized equations of motion for longitudinal dynamics. The stability and control characteristics of the system dynamics are investigated over a variety of mission trajectories including ascent, steady-state cruise and periodic cruise.
