Summary
A simple finite wake model for free streamline flow past a split plate is considered. An inverse problem is solved analytically by Riemann-Hilbert techniques. Numerical results for drag/lift are compared with experimental data for spoilers and split flaps and with theoretical results by Elcrat & Wentz (1983). Wakes of zero drag and wake overpressure are discussed.
Sunto
Si studia un semplice modello a scia finita per l'analisi teorica di spoiler e split flap. Si risolve analiticamente un problema inverso mediante tecniche alla Riemann-Hilbert, e si confrontano i risultati numerici per la resistenza e la portanza con dati sperimentali e teorici dovuti a Elcrat & Wentz (1983). Viene messa in luce la presenza di scie con resistenza nulla e con sovrapressione.
