A Review of Current Leading Edge Device Technology and of Options for Innovation Based on Flow Control
نویسندگان
چکیده
An innovative step change is required to improve or replace the current mechanically deployed leading edge high lift systems for civil transport aircraft. This paper provides a review of existing leading edge device technologies for high lift and possible future technologies based on flow control. There is an emphasis on those flow control technologies that will be sufficiently mature enough for implementation within the next decade. The characteristics of the flow control technologies are presented with regard to the practical implications of the implementation of a design. Nomenclature. CL Lift coefficient UC Cylinder surface velocity CLmax Maximum lift coefficient αstall Stall angle of incidence CD Drag coefficient αmax Max angle of incidence h Height (inches) ΔCL Change in CL Hz Hertz δ Boundary layer depth U Free stream velocity

Harmonic Reduction Technique Using Flying Capacitor Based Z Source Inverter for a DVR
The Dynamic Voltage Restorer (DVR) is a commercially available, popular device to eliminate voltage sags and swells in the distribution lines. Its basic function is to inject the voltage difference (difference between the pre-sag and sag voltage) to the power line and maintains the pre-sag voltage condition in the load side. The efficiency of the DVR depends on the performance of the efficiency...
متن کاملA Review on the Extent of Urban Design Intervention in Iran’s Architectural Structures for Interaction with Architectural Innovation
The intervention of urban design in Irans architectural structures has been for many years a challenging issue for architects and urban designers over their professional realm. The preservation of architectural structures in Iran has always resorted to extremes. This control and direction has sometimes resulted in exclusion of architecture position and has sometimes, once faced with lack of pro...
متن کاملExperimental Investigation of Asymmetry of Vortex Flow Over Single Delta Wings
It is generally believed that, on slender delta wings, there is a critical state at which strong asymmetric vortices are found along the leading edge on the lee-side of the delta wing. These asymmetric vortices can lead to high lateral forces even when slender delta wing is at the zero angle of yaw. Some experimental studies reported recently, cast considerable doubt as to the validity of the a...
