Experimental steady and unsteady aerodynamic and flutter results for HSCT semispan models

Identification of Nonlinear Aeroelastic Systems Based on the Volterra Theory: Progress and Opportunities

“…To this end, experiments designed to measure the unsteady aerodynamic response of various configurations provide significant and valuable information [64,71,86,99]. Experimental results are compared to various types of numerical analyses (such as CFD) to provide insight into the underlying physics of the problem.…”

“…Flutter of thin wings at subsonic conditions is typically independent of angleof-attack within the linear flow region. Figure 11.8 Silva et al [49] shows a summary of the flutter and high dynamic response regions for the RSM. Squares indicate conditions where forced response measurements due to trailing edge control surface oscillations were made.…”

“…The [48] acquired unsteady pressure data due to pitching oscillations and the RSM/PAPA test acquired flutter boundary data for simple pitching and plunging motions. The FSM test Silva et al [49] involved an aeroelastically-scaled model and was mounted to the TDT sidewall. The test acquired unsteady pressure data and flutter boundary data.…”

Transonic Dynamics Tunnel Aeroelastic Testing in Support of Aircraft Development

“…These two models were tested in the TDT a total of six times from 1994 to 1998, using both air and heavy gas as test mediums. Large steady and unsteady force and pressure databases 39 were obtained on these models in the form of angle-ofattack polars, steady control-surface de ection polars, and forced dynamic response caused by control-surface de ections.…”
