Numerical Study of a Novel Procedure for Installing the Tower and Rotor Nacelle Assembly of Offshore Wind Turbines Based on the Inverted Pendulum Principle

Current installation costs of offshore wind turbines(OWTs) are high and profit margins in the offshore wind energy sector are low, it is thus necessary to develop installation methods that are more efficient and practical. This paper presents a numerical study(based on a global response analysis of marine operations) of a novel procedure for installing the tower and Rotor Nacelle Assemblies(RNAs) on bottom-fixed foundations of OWTs. The installation procedure is based on the inverted pendulum principle. A cargo barge is used to transport the OWT assembly in a horizontal position to the site, and a medium-size Heavy Lift Vessel(HLV) is then employed to lift and up-end the OWT assembly using a special upending frame. The main advantage of this novel procedure is that the need for a huge HLV(in terms of lifting height and capacity) is eliminated. This novel method requires that the cargo barge is in the leeward side of the HLV(which can be positioned with the best heading) during the entire installation. This is to benefit from shielding effects of the HLV on the motions of the cargo barge, so the foundations need to be installed with a specific heading based on wave direction statistics of the site and a typical installation season. Following a systematic approach based on numerical simulations of actual operations, potential critical installation activities, corresponding critical events, and limiting(response) parameters are identified. In addition, operational limits for some of the limiting parameters are established in terms of allowable limits of sea states. Following a preliminary assessment of these operational limits, the duration of the entire operation, the equipment used, and weather-and water depth-sensitivity, this novel procedure is demonstrated to be viable.

Morphed Vertical Tailplane Assessment for Certification Requirements

Journal of Aerospace Science and Technology 2016年第1期2卷 34-41页

作者： Miguei A. Castillo-acero Cristina Cuemo-Rejado Miguel A. Gomez-Tierno ETSIAE- UPM Pza. Cardenal Cisneros 328040 Madrid Spain

The successful development of new high performance materials and actuators enable the controlled deformation of aerodynamic profiles for wing like type of structures. This paper presents the studies and conclusions of incorporating a novel morphing rudder for a commercial transport aircraft from the certification conditions perspective. This study provides the static directional-lateral stability evaluation of a two jet engined wing podded commercial transport aircraft when changing its conventional rudder configuration to a more aerodynamic efficient morphing configuration. The lateral force at morphed rudder deflection is set to increase 15% in relation to conventional configuration. The analysis is focused on the engine-out condition at take off which is critical for certification purposes. The analysis concludes the new configuration control surfaces trimming and slippage angle from static directional- lateral stability for this critical load case. The increment on heading moment available is also estimated for the new configuration. This augmentation is translated into minimum control speed requirements and its benefits are assessed.

＜正＞ We report our recent work on noise-robust large-vocabulary speech recognition. Three key innovations are developed and evaiuated in this work: 1) a new model learning paradigm that comprises a noise-insertion process followed by noise reduction2) a noise adaptive training algorithm that integrates noise reduction into probabilistic multi-styte system training: and 3)a next, algorithm （SPLICE） for noise reduction that makes no assumptions abort noise stationarity, Evaluation on a largevocabulary speech recognition task demonstrates signifieant and consistent error rate reduction using these techniques. The resulting error rate is shown to be lower than that achieved by the matched-noisy condition for both stationary and nonstationary natural, as well as simulated, noises.
