Free-Flight Aerodynamic Characteristic of the LDGP MK-82 CF Bomb at Subsonic and Transonic Velocities
Abstract
Free-flight tests were conducted in the Defence Research Establishment Valcartier (DREV) aeroballistic range on a 18.6% scaled model of the Low Drag General Purpose (LDGP) MK82 CF (Conical Fin) bomb from subsonic to low supersonic velocities. All the main aerodynamic coefficients and dynamic stability derivatives, as well as nonlinear ones were determined using the six-degree-of-freedom single- and multiple-fit data reduction techniques. The pitch moment coefficient was highly nonlinear at low angles of attack in the subsonic and transonic regimes. Estimates of the aerodynamic coefficients from three analytical codes and from one computational fluid dynamic analysis were compared with the free-flight results.
