This aircraft engine wing doesn’t have to be up in the air to fly through a cloud. Researchers at NASA Glenn can create a cloud on the ground at the Propulsion Systems Lab where they are investigating a rare type of icing that can form inside jet engines when flying through ice-crystal clouds at high altitude.

Bidwell. In January, NASA's Glenn Research Center began testing an aircraft engine in a high-altitude ice crystal environment, to explore a relatively new phenomenon called ice crystal : Kelly Heidman.

NASA’s icing research involves the development of tools and methods for evaluating and simulating the growth of ice on current and future aircraft surfaces or inside the engines and the effects that ice may have on the behavior of aircraft in flight.

At NASA Glenn Research Center, “We Freeze to Please”. Our icing research teams utilize a refrigerated wind. User’s Manual for the NASA Glenn Ice Accretion Code Lewice Version Available on Lewice release CD, ().

The de-icing ratio of Mode 4 was %, which was the maximum. The de-icing ratio of the electro-impulse de-icing system with four coils was %.Cited by: 1.

NASA’s Glenn Research Center has been a pioneer in the development of computational methods that estimate the collection of ice (or ice accretion) on an airfoil’s leading edge. This development included the implementation of these methods in a computer code called LEWICE (after the research center’s former name Lewis Research Center).

The method is first explained step by step with a practical example about snow accretion and then advanced usage examples of ice accretion are provided. Successively, the chapter includes examples of the application of mesh morphing in FEA for Fracture Mechanics demonstrating how crack update and propagation can be consistently by: 1.

LEWICE does not currently warn against using too many time steps. Based on the results in section 3, it is recommended that the user be warned against inputting too large a number of time steps.

Many groups also developed in-house icing codes. FENSAP-ICE: A Fully-3D In-Flight Icing Simulation System for Aircraft, Rotorcraft and UAVs automatic mesh adaptation module can be used to obtain optimal meshes that increase CFD accuracy without user intervention.

In this thesis, computational tools were used to better understand the flow over a large-scale, swept-wing, hybrid model mounted vertically in the NASA Glenn Icing Research Tunnel (IRT).

Fluent, a commercial CFD code, was used to calculate flows around the flapped-hybrid model in the IRT, mounted with the root at the floor and the tip at the.

The purpose of this book is only partly to record the engineering and scientific accomplishments of the men and women who made it possible for a human to step away from his home planet for the first time. The estimation of water droplet impingement is the first step toward a complete ice accretion assessment.

Predictions for the Annular Solar Eclipse of Aug 21 were generated using the VSOP87/ELP solar and lunar ephemerides and a value of ΔT = seconds.

The accuracy of the northern and southern edges of the eclipse path are limited to approximately kilometers due to the lunar limb profile.

Update The impact plumes of the Lunar CRater Observation and Sensing Satellite (LCROSS) and its Centaur rocket stage in Cabeus crater near the south pole of the Moon on 9 October showed the spectral signature of hydroxyl, a key indicator that water ice is present in the floor of the crater (1).

Analysis of the results indicates concentrations of roughly 6% water in the. Regarding a desire by NASA to possible find ice near the lunar poles in order to have an in situ source of water for a future moon base, would this be a finite source of this resource that could be exhausted, or could some analogy to a “hydrologic cycle” be established by the manner of natural resource utilization on the moon for ice/water or the other physical.
