Stability derivatives for a hypersonic caret-wing waverider

Analytical expressions for the longitudinal and lateral stability derivatives of caret-wing waveriders flying on-design are calculated using linear piston theory. The calculations are extended to off-design conditions with an attached shock wave using tangent wedge theory. The experimental work of Kipke is used to validate the lift and pitch stiffness coefficients. Agreement within 8% is achieved at a Mach number of 7.9 and a Reynolds number of 2.7 x 10(6). Good agreement is also found with the analytical work done by Hui. The stability derivatives of a Mach 6 waverider are computed, and it is found to have negative pitch and yaw stiffness with the c.g. at the center of volume.
