An experimental study of the sensitivity of helicopter rotor blade tracking to root pitch adjustment in hover
An experimental study of the sensitivity of helicopter
The sensitivity of blade tracking in hover to variations in root pitch was examined for two rotor configurations. Tests were conducted using a four bladed articulated rotor mounted on the NASA-Army aeroelastic rotor experimental system (ARES). Two rotor configurations were tested: one consisting of a blade set with flexible fiberglass spars and one with stiffer (by a factor of five in flapwise and torsional stiffnesses) aluminum spars. Both blade sets were identical in planform and airfoil distribution and were untwisted. The two configurations were ballasted to the same Lock number so that a direct comparison of the tracking sensitivity to a gross change in blade stiffness could be made. Experimental results show no large differences between the two sets of blades in the sensitivity of the blade tracking to root pitch adjustments. However, a measurable reduction in intrack coning of the fiberglass spar blades with respect to the aluminum blades is noted at higher rotor thrust conditions. Wilkie, W.

New Results in Numerical and Experimental Fluid Mechanics XI: Contributions to the 20th STAB/DGLR Symposium Braunschweig, Germany, 2016 (Notes on Numerical ... Mechanics and Multidisciplinary Design)
New Results in Numerical and Experimental Fluid Mechanics
This book gathers contributions to the 20th biannual symposium of the German Aerospace Aerodynamics Association (STAB) and the German Society for Aeronautics and Astronautics (DGLR). The individual chapters reflect ongoing research conducted by the STAB members in the field of numerical and experimental fluid mechanics and aerodynamics, mainly for (but not limited to) aerospace applications, and cover both nationally and EC-funded projects. Special emphasis is given to collaborative research projects conducted by German scientists and engineers from universities, research-establishments and industries. By addressing a number of cutting-edge applications, together with the relevant physical and mathematics fundamentals, the book provides readers with a comprehensive overview of the current research work in the field. Though the book’s primary emphasis is on the aerospace context, it also addresses further important applications, e.g. in ground transportation and energy.

Stockhausen: Helicopter String Quartet
Stockhausen: Helicopter String
Karlheinz Stockhausen's Helikopter-Streichquartett is one of the most controversial and talked-about works of art in recent years. Composed for the Arditti Quartet and premiered at the 1995 Holland Festival, it involves the four members of a string quartet playing in four different helicopters flying through the air. The music the quartet plays is then sent to a central space and mixed at a sound board. In his film Helicopter String Quartet, Frank Scheffer documents the complex preparations in the month leading up to the premiere of this work, as well as eliciting insights from the composer regarding how he conceived and executed it. Stockhausen tells Scheffer, for example, that the idea for the work came to him in a dream he had of musicians being able to fly. He then produced a fascinatingly original score in which each instrument is written in a different color, and in which the four string lines frequently jump from one staff to the other in order to imitate birds flying in different formations. Stockhausen also analyzes the content of the work for Scheffer, in particular showing how the writing for the quartet is meant to merge with the sonic characteristics of the helicopters. Scheffer goes behind the scenes and, stage by stage, shows the enormous production needed to reali...

Experimental assessment of helicopter rotor turbulence ingestion noise in hover
Experimental assessment of helicopter rotor turbulence ingestion noise
An experiment was conducted to assess the accuracy of a theory for non-isotropic turbulence ingestion. In order to generate non-isotropic turbulence in a controlled environment, a scale model rotor in a closed chamber was used so that the turbulence generated by the rotor was reingested by the recirculating flow. Simultaneous measurements of turbulence inflow properties and far field acoustics were acquired. Measurements confirmed that the inflow turbulence was highly non-isotropic. The measured aerodynamic properties were used as inputs for the noise prediction procedure. The general agreement between the non-isotropic noise prediction procedure and the experiment was good, although the procedure generally overpredicts the quasi-tonal low to mid range frequencies and underpredicts the higher broadband signals. The predicted sound power level as a function of polar angle was in close agreement with measurements, except near the rotor plane, which is not modeled by the present analysis. It is determined that the most sensitive parameter influencing the predicted noise was the turbulence intensity. Simonich, J. C. and Schlinker, R. H. and Amiet, R. K. Unspecified Center…
