Noise Characteristics of a Turbulent Crosswind Jet
AIAA Journal, 1974The turbulent flow which results when a circular jet issues into a crosswind is a noise source which is encountered during take-off and landing of certain types of V/STOL aircraft. The acoustic intensity of the noise from this flow is calculated by extending the freejet model of Ribner 1'2 to those crosswind jets for which the ratio of jet velocity to ...

Technical Stability of an Aircraft in a Crosswind Run
International Applied Mechanics, 2001The paper deals with the problem of technical stability of an aircraft take-off at lateral wind. Reviewer's remark: The author does not refer to the papers by \textit{A. A. Kayande} and \textit{M. Rama Mohana Rao} [Notes Comun. Math., Recife 20, 1--18 (1969; Zbl 0231.34048)] and \textit{A. A. Martynyuk} [Kibern. Vychisl. Tekhn. 15, Slozhn. Sist. Upravl.

Optical crosswind profiling system
Annual Meeting Optical Society of America, 1987A wind-profiling system has been developed that uses zero-mean transmitting and receiving filters to shape and analyze the intensity scintillation produced by refractive-index irregularities along the light path. The method is a variation of a technique first proposed by Lee.

Field Testing Of A Crosswind Scintillometer
SPIE Proceedings, 1989Field tests have been performed on a prototype spatially-averaged filter scintillometer designed to measure wind components transverse to an optical path. Unlike previous scintillometers, the spatially-averaged filter design peaks weighting functions at five segments along the optical path, producing simultaneous cross-path wind readings from these ...

Crosswind Kite Power with Tower
2018Crosswind kite power replaces the tower and the support structure of a conventional wind turbine by a lightweight tether leading to a potentially lower levelized cost of electricity. However, in this chapter it is shown that tethering the kite to the top of a tower instead of to the ground can have advantages: Most notably, the “cosine loss” is reduced,

An Investigation of an Inclined Jet in a Crosswind
Aeronautical Quarterly, 1977SummaryWind-tunnel experiments were conducted to determine the interference characteristics of an inclined turbulent jet exhausting from a flat plate into a turbulent subsonic crosswind. The jet was not yawed with respect to the undisturbed free stream.
