Summary

Lifting surface computer programs now exist for calculating the air forces on oscillating wings of general planform. These have made it practicable to evaluate the transient forces on wings entering step gusts by using a long-established relation between oscillatory and indicial forces. As examples, the indicial forces on a low aspect ratio wing in incompressible flow and the indicial pressures on a delta wing at a low subsonic Mach number are calculated. In the latter case the calculated results, which are based on attached flow, are compared with measurements on the same wing in conditions of separated flow. Despite the differences in flow, surprisingly similar development histories are found.
