Abstract
Free-flight tests were conducted in the Defence Research Establishment Valcartier (DREV) aeroballistic range on a full-scale MPB-LD (DBU-5002/B MOD 1) bomb from subsonic to transonic velocities. All the main aerodynamic coefficients and dynamic stability derivatives were very well determined using the six-degree-of-freedom single- and multiple-fit data reduction techniques. The cubic pitch moment and the cubic normal force coefficients terms, the yaw axial force term as well as induced moments were also reduced. Indraft wind tunnel and open jet facility experimental results were compared with the free flight ones. Estimates of the aerodynamic coefficients from two analytical codes and from one computational fluid dynamic analysis were compared with the free-flight results.
