An experimental and analytical investigation of proprotor whirl flutter [PDF]
The results of an experimental parametric investigation of whirl flutter are presented for a model consisting of a windmilling propeller-rotor, or proprotor, having blades with offset flapping hinges mounted on a rigid pylon with flexibility in pitch and

Comparison of analytical and wind-tunnel results for flutter and gust response of a transport wing with active controls [PDF]
Two flutter suppression control laws wre designed and tested on a low speed aeroelastic model of a DC-10 derivative wing. Both control laws demontrated increases in flutter speed in excess of 25 percent above the passive wing flutter speed.

Building a Bridge Between Ambient MS and LC‐MS by Non‐Exhaustive Microdesorption
Angewandte Chemie International Edition, Accepted Article.Ambient mass spectrometry (AMS) offers rapid screening but faces challenges in analyzing complex samples due to high matrix effects and limited selectivity. The absence of a separation step can also lead to false positives due to the isomers or isobars.

Supersonic unstalled flutter [PDF]
Flutter analyses were developed to predict the onset of supersonic unstalled flutter of a cascade of two-dimensional airfoils. The first of these analyzes the onset of supersonic flutter at low levels of aerodynamic loading (i.e., backpressure), while ...
