Numerical Simulations of the Adverse Effects of Rain on Airfoil And Rotor Aerodynamic Characteristics
Autor: Aishwerya S. Gahlot, Ritu M. Eshcol, Lakshmi N. Sankar, Richard E. Kreeger
Publikováno v: Journal of the American Helicopter Society. 68:33-41
There is a significant interest in improving the performance of rotors under adverse operating conditions. However, there is a very limited understanding of the performance implications on two-dimensional (2D) airfoils and rotor blades under adverse

Super-Cooled Large Droplet Experimental Reproduction, Ice Shape Modeling, and Scaling Method Assessment
Autor: Richard E. Kreeger, Jose Palacios, Edward T. Rocco, Yiqiang Han
Publikováno v: AIAA Journal. 59:1277-1295
Super-cooled large droplets (SLDs) present a unique experimental challenge for conventional horizontal spray icing wind tunnels due to gravity effects on the droplets and coalescence between the pa...

Experimental evaluation of the impact behavior of partially melted ice particles
Autor: Richard E. Kreeger, Miguel Alvarez, Jose Palacios
Publikováno v: International Journal of Impact Engineering. 123:70-76
Operations in ice crystals conditions are a threat to commercial aviation. The ingestion of ice crystals can affect different aircraft probes but can also affect jet engines. As fully frozen ice crystals enter an engine, partial melting occurs on the

Application of Extended Messinger Models to Complex Geometries
Autor: Richard E. Kreeger, Avani Gupta, Lakshmi N. Sankar
Publikováno v: SAE Technical Paper Series.
Since, ice accretion can significantly degrade the performance and the stability of an airborne vehicle, it is imperative to be able to model it accurately. While ice accretion studies have been performed on airplane wings and helicopter blades in ab

Measured Interfacial Residual Strains Produced by In-Flight Ice
Autor: Rebekah G. Douglass, Richard E. Kreeger, Andrew H. Work, Jonathan A. Salem, Eric H. Baker, Ernestina Schirmer
Publikováno v: SAE Technical Paper Series.
The formation of ice on aircraft is a highly dynamic process during which ice will expand and contract upon freezing and undergoing changes in temperature. Finite Element Analysis (FEA) simulations were performed investigating the stress build up in

Collaborative Experiments and Computations in Aircraft Icing
Autor: Richard E. Kreeger, Andy P. Broeren
Publikováno v: 2018 Applied Aerodynamics Conference.
The formation of ice over lifting surfaces can affect aerodynamic performance. The ability to predict ice accumulation and the resulting degradation in vehicle performance is essential to determine the limitations of aircraft in icing encounters. The
