Book An Airport Wind Shear Detection and Warning System Using Doppler Radar

Download or read book An Airport Wind Shear Detection and Warning System Using Doppler Radar written by John McCarthy and published by . This book was released on 1981 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: A feasibility study was conducted to determine whether ground based Doppler radar could measure the wind along the path of an approaching aircraft with sufficient accuracy to predict aircraft performance. Forty-three PAR approaches were conducted, with 16 examined in detail. In each, Doppler derived longitudinal winds were compared to aircraft measured winds; in approximately 75 percent of the cases, the Doppler and aircraft winds were in acceptable agreement. In the remaining cases, errors may have been due to a lack of Doppler resolution, a lack of co-location of the two sampling volumes, the presence of eddy or vortex like disturbances within the pulse volume, or the presence of point targets in antenna side lobes. It was further concluded that shrouding techniques would have reduced the side lobe problem. A ground based Doppler radar operating in the optically clear air, provides the appropriate longitudinal winds along an aircraft's intended flight path. (NTRL site)

Book A High Resolution Spatial and Temporal Multiple Doppler Analysis of a Microburst and Its Application to Aircraft Flight Simulation

Download or read book A High Resolution Spatial and Temporal Multiple Doppler Analysis of a Microburst and Its Application to Aircraft Flight Simulation written by and published by . This book was released on 1987 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiple Doppler radar data collected during the Joint Airport Weather Studies (JAWS) Project are used to synthesize the three-dimensional wind in the region of a microburst. The particular microburst used in this study is the strongest one to date for which three-dimensional winds have been recovered. As a diagnostic tool, a six-degree-of-freedom numerical aircraft model having characteristic similar to Boeing 727 series aircraft is used to investigate jet transport aircraft response to observed microburst winds during simulated approaches and departures. Simple pilot control laws are used to adjust thrust, pitch, roll, and yaw so as to maintain given approach or departure path is 0.01 per sec greater, the model is unable to maintain the desired approach path and suffers a significant reduction in climb performance during a go-around or departure. Although the mean wind shear along a path gives a good qualitative measure of the wind shear threat to a jet transport, different paths with similar mean shears can yield markedly different results, as do the same paths through the microburst at different times. These findings are a direct consequence of the fine temporal and spatial scale of microburst winds. During any given modelled aircraft traverse through the region of highest horizontal shear, time variations in the microburst wind field are shown to have an insignificant effect on the modelled flight path. This is because the traverse period is short (30 s) compared to the lifetime of a microburst (300-600 s). (Author).
