Lift and moment responses to penetration of sharp-edged traveling gusts, with application to penetration of weak blast waves
Year: 1957
Abstract: The lift and moment responses to penetration of sharp-edged traveling gusts are calculated for wings in incompressible and supersonic tow-dimensional flow, for wide delta and rectangular wings in supersonic flow, and for very narrow delta wings. By using the two-dimensional indicial-lift functions, some calculations of normal-acceleration response are made for two mass ratios.
The results of these calculations indicate that the forward speed of the gusts has a large effect on the lift- and moment-response functions. For incompressible flow, peaks exist in the early portion of the lift response, which may be much larger than the steady-state value. Some peaks also occur in the lift-response functions for supersonic speeds but are much less pronounced and exceed the steady-state value in only a few Instances
